text: Drosophila melanogaster plasmatocytes, the phagocytic cells among hemocytes,
are essential for immune responses, but also play key roles from early development
to death through their interactions with other cell types. They regulate homeostasis
and signaling during development, stem cell proliferation, metabolism, cancer,
wound responses and aging, displaying intriguing molecular and functional conservation
with vertebrate macrophages. Given the relative ease of genetics in Drosophila
compared to vertebrates, tools permitting visualization and genetic manipulation
of plasmatocytes and surrounding tissues independently at all stages would greatly
aid in fully understanding these processes, but are lacking. Here we describe
a comprehensive set of transgenic lines that allow this. These include extremely
brightly fluorescing mCherry-based lines that allow GAL4-independent visualization
of plasmatocyte nuclei, cytoplasm or actin cytoskeleton from embryonic Stage 8
through adulthood in both live and fixed samples even as heterozygotes, greatly
facilitating screening. These lines allow live visualization and tracking of embryonic
plasmatocytes, as well as larval plasmatocytes residing at the body wall or flowing
with the surrounding hemolymph. With confocal imaging, interactions of plasmatocytes
and inner tissues can be seen in live or fixed embryos, larvae and adults. They
permit efficient GAL4-independent FACS analysis/sorting of plasmatocytes throughout
life. To facilitate genetic analysis of reciprocal signaling, we have also made
a plasmatocyte-expressing QF2 line that in combination with extant GAL4 drivers
allows independent genetic manipulation of both plasmatocytes and surrounding
tissues, and a GAL80 line that blocks GAL4 drivers from affecting plasmatocytes,
both of which function from the early embryo to the adult.

text: Although much is known about the physiological framework of T cell motility,
and numerous rate-limiting molecules have been identified through loss-of-function
approaches, an integrated functional concept of T cell motility is lacking. Here,
we used in vivo precision morphometry together with analysis of cytoskeletal dynamics
in vitro to deconstruct the basic mechanisms of T cell migration within lymphatic
organs. We show that the contributions of the integrin LFA-1 and the chemokine
receptor CCR7 are complementary rather than positioned in a linear pathway, as
they are during leukocyte extravasation from the blood vasculature. Our data demonstrate
that CCR7 controls cortical actin flows, whereas integrins mediate substrate friction
that is sufficient to drive locomotion in the absence of considerable surface
adhesions and plasma membrane flux.

text: We show that a rather simple, steady modification of the streamwise velocity
profile in a pipe can lead to a complete collapse of turbulence and the flow fully
relaminarizes. Two different devices, a stationary obstacle (inset) and a device
which injects fluid through an annular gap close to the wall, are used to control
the flow. Both devices modify the streamwise velocity profile such that the flow
in the center of the pipe is decelerated and the flow in the near wall region
is accelerated. We present measurements with stereoscopic particle image velocimetry
to investigate and capture the development of the relaminarizing flow downstream
these devices and the specific circumstances responsible for relaminarization.
We find total relaminarization up to Reynolds numbers of 6000, where the skin
friction in the far downstream distance is reduced by a factor of 3.4 due to relaminarization.
In a smooth straight pipe the flow remains completely laminar downstream of the
control. Furthermore, we show that transient (temporary) relaminarization in a
spatially confined region right downstream the devices occurs also at much higher
Reynolds numbers, accompanied by a significant local skin friction drag reduction.
The underlying physical mechanism of relaminarization is attributed to a weakening
of the near-wall turbulence production cycle.

text: Turbulence is the major cause of friction losses in transport processes and
it is responsible for a drastic drag increase in flows over bounding surfaces.
While much effort is invested into developing ways to control and reduce turbulence
intensities, so far no methods exist to altogether eliminate turbulence if velocities
are sufficiently large. We demonstrate for pipe flow that appropriate distortions
to the velocity profile lead to a complete collapse of turbulence and subsequently
friction losses are reduced by as much as 90%. Counterintuitively, the return
to laminar motion is accomplished by initially increasing turbulence intensities
or by transiently amplifying wall shear. Since neither the Reynolds number nor
the shear stresses decrease (the latter often increase), these measures are not
indicative of turbulence collapse. Instead, an amplification mechanism measuring
the interaction between eddies and the mean shear is found to set a threshold
below which turbulence is suppressed beyond recovery.

text: The t-haplotype, a mouse meiotic driver found on chromosome 17, has been a
model for autosomal segregation distortion for close to a century, but several
questions remain regarding its biology and evolutionary history. A recently published
set of population genomics resources for wild mice includes several individuals
heterozygous for the t-haplotype, which we use to characterize this selfish element
at the genomic and transcriptomic level. Our results show that large sections
of the t-haplotype have been replaced by standard homologous sequences, possibly
due to occasional events of recombination, and that this complicates the inference
of its history. As expected for a long genomic segment of very low recombination,
the t-haplotype carries an excess of fixed nonsynonymous mutations compared to
the standard chromosome. This excess is stronger for regions that have not undergone
recent recombination, suggesting that occasional gene flow between the t and the
standard chromosome may provide a mechanism to regenerate coding sequences that
have accumulated deleterious mutations. Finally, we find that t-complex genes
with altered expression largely overlap with deleted or amplified regions, and
that carrying a t-haplotype alters the testis expression of genes outside of the
t-complex, providing new leads into the pathways involved in the biology of this
segregation distorter.

text: Clathrin-mediated endocytosis (CME) is a cellular trafficking process in which
cargoes and lipids are internalized from the plasma membrane into vesicles coated
with clathrin and adaptor proteins. CME is essential for many developmental and
physiological processes in plants, but its underlying mechanism is not well characterised
compared to that in yeast and animal systems. Here, we searched for new factors
involved in CME in Arabidopsis thaliana by performing Tandem Affinity Purification
of proteins that interact with clathrin light chain, a principal component of
the clathrin coat. Among the confirmed interactors, we found two putative homologues
of the clathrin-coat uncoating factor auxilin previously described in non-plant
systems. Overexpression of AUXILIN-LIKE1 and AUXILIN-LIKE2 in A. thaliana caused
an arrest of seedling growth and development. This was concomitant with inhibited
endocytosis due to blocking of clathrin recruitment after the initial step of
adaptor protein binding to the plasma membrane. By contrast, auxilin-like(1/2)
loss-of-function lines did not present endocytosis-related developmental or cellular
phenotypes under normal growth conditions. This work contributes to the on-going
characterization of the endocytotic machinery in plants and provides a robust
tool for conditionally and specifically interfering with CME in A. thaliana.

text: 'The hippocampus is a key brain region for spatial memory and navigation and
is needed at all stages of memory, including encoding, consolidation, and recall.
Hippocampal place cells selectively discharge at specific locations of the environment
to form a cognitive map of the space. During the rest period and sleep following
spatial navigation and/or learning, the waking activity of the place cells is
reactivated within high synchrony events. This reactivation is thought to be important
for memory consolidation and stabilization of the spatial representations. The
aim of my thesis was to directly test whether the reactivation content encoded
in firing patterns of place cells is important for consolidation of spatial memories.
In particular, I aimed to test whether, in cases when multiple spatial memory
traces are acquired during learning, the specific disruption of the reactivation
of a subset of these memories leads to the selective disruption of the corresponding
memory traces or through memory interference the other learned memories are disrupted
as well. In this thesis, using a modified cheeseboard paradigm and a closed-loop
recording setup with feedback optogenetic stimulation, I examined how the disruption
of the reactivation of specific spiking patterns affects consolidation of the
corresponding memory traces. To obtain multiple distinctive memories, animals
had to perform a spatial task in two distinct cheeseboard environments and the
reactivation of spiking patterns associated with one of the environments (target)
was disrupted after learning during four hours rest period using a real-time decoding
method. This real-time decoding method was capable of selectively affecting the
firing rates and cofiring correlations of the target environment-encoding cells.
The selective disruption led to behavioural impairment in the memory tests after
the rest periods in the target environment but not in the other undisrupted control
environment. In addition, the map of the target environment was less stable in
the impaired memory tests compared to the learning session before than the map
of the control environment. However, when the animal relearned the task, the same
map recurred in the target environment that was present during learning before
the disruption. Altogether my work demonstrated that the reactivation content
is important: assembly-related disruption of reactivation can lead to a selective
memory impairment and deficiency in map stability. These findings indeed suggest
that reactivated assembly patterns reflect processes associated with the consolidation
of memory traces. '

and feedback inhibition, network oscillations, and pattern separation. Fast lateral
inhibition mediated by GABAergic interneurons may implement a winner-takes-all
mechanism in the hippocampal input layer. However, it is not clear whether the
functional connectivity rules of granule cells (GCs) and interneurons in the dentate
gyrus are consistent with such a mechanism. Using simultaneous patch-clamp recordings
from up to seven GCs and up to four PV+ interneurons in the dentate gyrus, we
find that connectivity is structured in space, synapse-specific, and enriched
in specific disynaptic motifs. In contrast to the neocortex, lateral inhibition
in the dentate gyrus (in which a GC inhibits neighboring GCs via a PV+ interneuron)
is ~ 10-times more abundant than recurrent inhibition (in which a GC inhibits
itself). Thus, unique connectivity rules may enable the dentate gyrus to perform
specific higher-order computations

text: 'Gene regulatory networks evolve through rewiring of individual components—that
is, through changes in regulatory connections. However, the mechanistic basis
of regulatory rewiring is poorly understood. Using a canonical gene regulatory
system, we quantify the properties of transcription factors that determine the
evolutionary potential for rewiring of regulatory connections: robustness, tunability
and evolvability. In vivo repression measurements of two repressors at mutated
operator sites reveal their contrasting evolutionary potential: while robustness
and evolvability were positively correlated, both were in trade-off with tunability.
Epistatic interactions between adjacent operators alleviated this trade-off. A
thermodynamic model explains how the differences in robustness, tunability and
evolvability arise from biophysical characteristics of repressor–DNA binding.
The model also uncovers that the energy matrix, which describes how mutations
affect repressor–DNA binding, encodes crucial information about the evolutionary
potential of a repressor. The biophysical determinants of evolutionary potential
for regulatory rewiring constitute a mechanistic framework for understanding network
evolution.'

text: The Wnt/planar cell polarity (Wnt/PCP) pathway determines planar polarity
of epithelial cells in both vertebrates and invertebrates. The role that Wnt/PCP
signaling plays in mesenchymal contexts, however, is only poorly understood. While
previous studies have demonstrated the capacity of Wnt/PCP signaling to polarize
and guide directed migration of mesenchymal cells, it remains unclear whether
endogenous Wnt/PCP signaling performs these functions instructively, as it does
in epithelial cells. Here we developed a light-switchable version of the Wnt/PCP
receptor Frizzled 7 (Fz7) to unambiguously distinguish between an instructive
and a permissive role of Wnt/PCP signaling for the directional collective migration
of mesendoderm progenitor cells during zebrafish gastrulation. We show that prechordal
plate (ppl) cell migration is defective in maternal-zygotic fz7a and fz7b (MZ
fz7a,b) double mutant embryos, and that Fz7 functions cell-autonomously in this
process by promoting ppl cell protrusion formation and directed migration. We
further show that local activation of Fz7 can direct ppl cell migration both in
vitro and in vivo. Surprisingly, however, uniform Fz7 activation is sufficient
to fully rescue the ppl cell migration defect in MZ fz7a,b mutant embryos, indicating
that Wnt/PCP signaling functions permissively rather than instructively in directed
mesendoderm cell migration during zebrafish gastrulation.

text: 'A major challenge in neuroscience research is to dissect the circuits that
orchestrate behavior in health and disease. Proteins from a wide range of non-mammalian
species, such as microbial opsins, have been successfully transplanted to specific
neuronal targets to override their natural communication patterns. The goal of
our work is to manipulate synaptic communication in a manner that closely incorporates
the functional intricacies of synapses by preserving temporal encoding (i.e. the
firing pattern of the presynaptic neuron) and connectivity (i.e. target specific
synapses rather than specific neurons). Our strategy to achieve this goal builds
on the use of non-mammalian transplants to create a synthetic synapse. The mode
of modulation comes from pre-synaptic uptake of a synthetic neurotransmitter (SN)
into synaptic vesicles by means of a genetically targeted transporter selective
for the SN. Upon natural vesicular release, exposure of the SN to the synaptic
cleft will modify the post-synaptic potential through an orthogonal ligand gated
ion channel. To achieve this goal we have functionally characterized a mixed cationic
methionine-gated ion channel from Arabidopsis thaliana, designed a method to functionally
characterize a synthetic transporter in isolated synaptic vesicles without the
need for transgenic animals, identified and extracted multiple prokaryotic uptake
systems that are substrate specific for methionine (Met), and established a primary/cell
line co-culture system that would allow future combinatorial testing of this orthogonal
transmitter-transporter-channel trifecta. Synthetic synapses will provide a unique
opportunity to manipulate synaptic communication while maintaining the electrophysiological
integrity of the pre-synaptic cell. In this way, information may be preserved
that was generated in upstream circuits and that could be essential for concerted
function and information processing. '

text: Solid-state qubit manipulation and read-out fidelities are reaching fault-tolerance,
but quantum error correction requires millions of physical qubits and therefore
a scalable quantum computer architecture. To solve signal-line bandwidth and fan-out
problems, microwave sources required for qubit manipulation might be embedded
close to the qubit chip, typically operating at temperatures below 4 K. Here,
we perform the first low temperature measurements of a 130 nm BiCMOS based SiGe
voltage controlled oscillator at cryogenic temperature. We determined the frequency
and output power dependence on temperature and magnetic field up to 5 T and measured
the temperature influence on its noise performance. The device maintains its full
functionality from 300 K to 4 K. The carrier frequency at 4 K increases by 3%
with respect to the carrier frequency at 300 K, and the output power at 4 K increases
by 10 dB relative to the output power at 300 K. The frequency tuning range of
approximately 20% remains unchanged between 300 K and 4 K. In an in-plane magnetic
field of 5 T, the carrier frequency shifts by only 0.02% compared to the frequency
at zero magnetic field.

text: Indirect reciprocity explores how humans act when their reputation is at stake,
and which social norms they use to assess the actions of others. A crucial question
in indirect reciprocity is which social norms can maintain stable cooperation
in a society. Past research has highlighted eight such norms, called “leading-eight”
strategies. This past research, however, is based on the assumption that all relevant
information about other population members is publicly available and that everyone
agrees on who is good or bad. Instead, here we explore the reputation dynamics
when information is private and noisy. We show that under these conditions, most
leading-eight strategies fail to evolve. Those leading-eight strategies that do
evolve are unable to sustain full cooperation.Indirect reciprocity is a mechanism
for cooperation based on shared moral systems and individual reputations. It assumes
that members of a community routinely observe and assess each other and that they
use this information to decide who is good or bad, and who deserves cooperation.
When information is transmitted publicly, such that all community members agree
on each other’s reputation, previous research has highlighted eight crucial moral
systems. These “leading-eight” strategies can maintain cooperation and resist
invasion by defectors. However, in real populations individuals often hold their
own private views of others. Once two individuals disagree about their opinion
of some third party, they may also see its subsequent actions in a different light.
Their opinions may further diverge over time. Herein, we explore indirect reciprocity
when information transmission is private and noisy. We find that in the presence
of perception errors, most leading-eight strategies cease to be stable. Even if
a leading-eight strategy evolves, cooperation rates may drop considerably when
errors are common. Our research highlights the role of reliable information and
synchronized reputations to maintain stable moral systems.

text: The rapid auxin-triggered growth of the Arabidopsis hypocotyls involves the
nuclear TIR1/AFB-Aux/IAA signaling and is accompanied by acidification of the
apoplast and cell walls (Fendrych et al., 2016). Here, we describe in detail the
method for analysis of the elongation and the TIR1/AFB-Aux/IAA-dependent auxin
response in hypocotyl segments as well as the determination of relative values
of the cell wall pH.

text: 'Autism spectrum disorders (ASD) are a group of genetic disorders often overlapping
with other neurological conditions. Despite the remarkable number of scientific
breakthroughs of the last 100 years, the treatment of neurodevelopmental disorders
(e.g. autism spectrum disorder, intellectual disability, epilepsy) remains a great
challenge. Recent advancements in geno mics, like whole-exome or whole-genome
sequencing, have enabled scientists to identify numerous mutations underlying
neurodevelopmental disorders. Given the few hundred risk genes that were discovered,
the etiological variability and the heterogeneous phenotypic outcomes, the need
for genotype -along with phenotype- based diagnosis of individual patients becomes
a requisite. Driven by this rationale, in a previous study our group described
mutations, identified via whole - exome sequencing, in the gene BCKDK – encoding
for a key regulator of branched chain amin o acid (BCAA) catabolism - as a cause
of ASD. Following up on the role of BCAAs, in the study described here we show
that the solute carrier transporter 7a5 (SLC7A5), a large neutral amino acid transporter
localized mainly at the blood brain barrier (BBB), has an essential role in maintaining
normal levels of brain BCAAs. In mice, deletion of Slc7a5 from the endothelial
cells of the BBB leads to atypical brain amino acid profile, abnormal mRNA translation
and severe neurolo gical abnormalities. Additionally, deletion of Slc7a5 from
the neural progenitor cell population leads to microcephaly. Interestingly, we
demonstrate that BCAA intracerebroventricular administration ameliorates abnormal
behaviors in adult mutant mice. Furthermore, whole - exome sequencing of patients
diagnosed with neurological dis o r ders helped us identify several patients with
autistic traits, microcephaly and motor delay carrying deleterious homozygous
mutations in the SLC7A5 gene. In conclusion, our data elucidate a neurological
syndrome defined by SLC7A5 mutations and support an essential role for t he BCAA
s in human bra in function. Together with r ecent studies (described in chapter
two) that have successfully made the transition into clinical practice, our findings
on the role of B CAAs might have a crucial impact on the development of novel
individualized therapeutic strategies for ASD. '

text: Plant hormones as signalling molecules play an essential role in the control
of plant growth and development. Typically, sites of hormonal action are usually
distant from the site of biosynthesis thus relying on efficient transport mechanisms.
Over the last decades, molecular identification of proteins and protein complexes
involved in hormonal transport has started. Advanced screens for genes involved
in hormonal transport in combination with transport assays using heterologous
systems such as yeast, insect, or tobacco BY2 cells or Xenopus oocytes provided
important insights into mechanisms underlying distribution of hormones in plant
body and led to identification of principal transporters for each hormone. This
review gives a short overview of the mechanisms of hormonal transport and transporters
identified in Arabidopsis thaliana.

text: 'In the here presented thesis, we explore the role of branched actin networks
in cell migration and antigen presentation, the two most relevant processes in
dendritic cell biology. Branched actin networks construct lamellipodial protrusions
at the leading edge of migrating cells. These are typically seen as adhesive structures,
which mediate force transduction to the extracellular matrix that leads to forward
locomotion. We ablated Arp2/3 nucleation promoting factor WAVE in DCs and found
that the resulting cells lack lamellipodial protrusions. Instead, depending on
the maturation state, one or multiple filopodia were formed. By challenging these
cells in a variety of migration assays we found that lamellipodial protrusions
are dispensable for the locomotion of leukocytes and actually dampen the speed
of migration. However, lamellipodia are critically required to negotiate complex
environments that DCs experience while they travel to the next draining lymph
node. Taken together our results suggest that leukocyte lamellipodia have rather
a sensory- than a force transducing function. Furthermore, we show for the first
time structure and dynamics of dendritic cell F-actin at the immunological synapse
with naïve T cells. Dendritic cell F-actin appears as dynamic foci that are nucleated
by the Arp2/3 complex. WAVE ablated dendritic cells show increased membrane tension,
leading to an altered ultrastructure of the immunological synapse and severe T
cell priming defects. These results point towards a previously unappreciated role
of the cellular mechanics of dendritic cells in T cell activation. Additionally,
we present a novel cell culture based system for the differentiation of dendritic
cells from conditionally immortalized hematopoietic precursors. These precursor
cells are genetically tractable via the CRISPR/Cas9 system while they retain their
ability to differentiate into highly migratory dendritic cells and other immune
cells. This will foster the study of all aspects of dendritic cell biology and
beyond. '

text: Auxin is unique among plant hormones due to its directional transport that
is mediated by the polarly distributed PIN auxin transporters at the plasma membrane.
The canalization hypothesis proposes that the auxin feedback on its polar flow
is a crucial, plant-specific mechanism mediating multiple self-organizing developmental
processes. Here, we used the auxin effect on the PIN polar localization in Arabidopsis
thaliana roots as a proxy for the auxin feedback on the PIN polarity during canalization.
We performed microarray experiments to find regulators of this process that act
downstream of auxin. We identified genes that were transcriptionally regulated
by auxin in an AXR3/IAA17- and ARF7/ARF19-dependent manner. Besides the known
components of the PIN polarity, such as PID and PIP5K kinases, a number of potential
new regulators were detected, among which the WRKY23 transcription factor, which
was characterized in more detail. Gain- and loss-of-function mutants confirmed
a role for WRKY23 in mediating the auxin effect on the PIN polarity. Accordingly,
processes requiring auxin-mediated PIN polarity rearrangements, such as vascular
tissue development during leaf venation, showed a higher WRKY23 expression and
required the WRKY23 activity. Our results provide initial insights into the auxin
transcriptional network acting upstream of PIN polarization and, potentially,
canalization-mediated plant development.

text: Intercellular distribution of the plant hormone auxin largely depends on the
polar subcellular distribution of the plasma membrane PIN-FORMED (PIN) auxin transporters.
PIN polarity switches in response to different developmental and environmental
signals have been shown to redirect auxin fluxes mediating certain developmental
responses. PIN phosphorylation at different sites and by different kinases is
crucial for PIN function. Here we investigate the role of PIN phosphorylation
during gravitropic response. Loss- and gain-of-function mutants in PINOID and
related kinases but not in D6PK kinase as well as mutations mimicking constitutive
dephosphorylated or phosphorylated status of two clusters of predicted phosphorylation
sites partially disrupted PIN3 phosphorylation and caused defects in gravitropic
bending in roots and hypocotyls. In particular, they impacted PIN3 polarity rearrangements
in response to gravity and during feed-back regulation by auxin itself. Thus PIN
phosphorylation, besides regulating transport activity and apical-basal targeting,
is also important for the rapid polarity switches in response to environmental
and endogenous signals.
