text: All metazoan cells carry transmembrane receptors of the integrin family, which
couple the contractile force of the actomyosin cytoskeleton to the extracellular
environment. In agreement with this principle, rapidly migrating leukocytes use
integrin-mediated adhesion when moving over two-dimensional surfaces. As migration
on two-dimensional substrates naturally overemphasizes the role of adhesion, the
contribution of integrins during three-dimensional movement of leukocytes within
tissues has remained controversial. We studied the interplay between adhesive,
contractile and protrusive forces during interstitial leukocyte chemotaxis in
vivo and in vitro. We ablated all integrin heterodimers from murine leukocytes,
and show here that functional integrins do not contribute to migration in three-dimensional
environments. Instead, these cells migrate by the sole force of actin-network
expansion, which promotes protrusive flowing of the leading edge. Myosin II-dependent
contraction is only required on passage through narrow gaps, where a squeezing
contraction of the trailing edge propels the rigid nucleus.

text: Recent in vitro studies have suggested a role for sialylation in chemokine
receptor binding to its ligand (Bannert, N., S. Craig, M. Farzan, D. Sogah, N.V.
Santo, H. Choe, and J. Sodroski. 2001. J. Exp. Med. 194:1661-1673). This prompted
us to investigate chemokine-induced leukocyte adhesion in inflamed cremaster muscle
venules of alpha2,3 sialyltransferase (ST3Gal-IV)-deficient mice. We found a marked
reduction in leukocyte adhesion to inflamed microvessels upon injection of the
CXCR2 ligands CXCL1 (keratinocyte-derived chemokine) or CXCL8 (interleukin 8).
In addition, extravasation of ST3Gal-IV(-/-) neutrophils into thioglycollate-pretreated
peritoneal cavities was significantly decreased. In vitro assays revealed that
CXCL8 binding to isolated ST3Gal-IV(-/-) neutrophils was markedly impaired. Furthermore,
CXCL1-mediated adhesion of ST3Gal-IV(-/-) leukocytes at physiological flow conditions,
as well as transendothelial migration of ST3Gal-IV(-/-) leukocytes in response
to CXCL1, was significantly reduced. In human neutrophils, enzymatic desialylation
decreased binding of CXCR2 ligands to the neutrophil surface and diminished neutrophil
degranulation in response to these chemokines. In addition, binding of alpha2,3-linked
sialic acid-specific Maackia amurensis lectin II to purified CXCR2 from neuraminidase-treated
CXCR2-transfected HEK293 cells was markedly impaired. Collectively, we provide
substantial evidence that sialylation by ST3Gal-IV significantly contributes to
CXCR2-mediated leukocyte adhesion during inflammation in vivo.

text: Neutrophil granulocytes form the body's first line of antibacterial defense,
but they also contribute to tissue injury and noninfectious, chronic inflammation.
Proteinase 3 (PR3) and neutrophil elastase (NE) are 2 abundant neutrophil serine
proteases implicated in antimicrobial defense with overlapping and potentially
redundant substrate specificity. Here, we unraveled a cooperative role for PR3
and NE in neutrophil activation and noninfectious inflammation in vivo, which
we believe to be novel. Mice lacking both PR3 and NE demonstrated strongly diminished
immune complex-mediated (IC-mediated) neutrophil infiltration in vivo as well
as reduced activation of isolated neutrophils by ICs in vitro. In contrast, in
mice lacking just NE, neutrophil recruitment to ICs was only marginally impaired.
The defects in mice lacking both PR3 and NE were directly linked to the accumulation
of antiinflammatory progranulin (PGRN). Both PR3 and NE cleaved PGRN in vitro
and during neutrophil activation and inflammation in vivo. Local administration
of recombinant PGRN potently inhibited neutrophilic inflammation in vivo, demonstrating
that PGRN represents a crucial inflammation-suppressing mediator. We conclude
that PR3 and NE enhance neutrophil-dependent inflammation by eliminating the local
antiinflammatory activity of PGRN. Our results support the use of serine protease
inhibitors as antiinflammatory agents.

text: Live imaging of the actin cytoskeleton is crucial for the study of many fundamental
biological processes, but current approaches to visualize actin have several limitations.
Here we describe Lifeact, a 17-amino-acid peptide, which stained filamentous actin
(F-actin) structures in eukaryotic cells and tissues. Lifeact did not interfere
with actin dynamics in vitro and in vivo and in its chemically modified peptide
form allowed visualization of actin dynamics in nontransfectable cells.

text: Langerhans cells and dermal dendritic cells migrate to the draining lymph
nodes through dermal lymphatic vessels. They do so in the steady-state and under
inflammatory conditions. Peripheral T cell tolerance or T cell priming, respectively,
are the consequences of migration. The nature of dendritic cell-containing vessels
was mostly defined by electron microscopy or by their lack of blood endothelial
markers. Selective markers for murine lymph endothelium were hitherto rare or
not available. Here, we utilised recently developed antibodies against the murine
hyaluronan receptor, LYVE-1, to study the lymph vessel network in mouse skin in
more detail. In hairless skin from the ears, lymph vessels were spread out in
a horizontal plane. They formed anastomoses, and they possessed frequent blind
endings that were occasionally open. Lymph vessels were wider than blood vessels,
which were identified by their strong CD31 expression. In body wall skin LYVE-1
reactive vessels did not extend laterally but they dived straight down into the
deeper dermis. There, they are connected to each other and formed a network similar
to ear skin. The number and width of lymph vessels did not grossly change upon
inflammatory stimuli such as skin explant culture or tape stripping. There were
also no marked changes in caliber in response to the TLR 7/8 ligand Imiquimod.
Double-labelling experiments of cultured skin showed that most of the strongly
cell surface MHC II-expressing (i.e. activated) dendritic cells were confined
to the lymph vessels. Langerin/CD207(+) cells within this population appeared
later than dermal dendritic cells, i.e. langerin-negative cells. Comparable results
were obtained after stimulating the skin in vivo with the TLR 7/8 ligand Imiquimod
or by tape stripping. In untreated skin (i.e. steady state) a few MHC II(+) and
Langerin/CD207(+) cells, presumably migrating skin dendritic cells including epidermal
Langerhans cells, were consistently observed within the lymph vessels. The novel
antibody reagents may serve as important tools to further study the dendritic
cell traffic in the skin under physiological conditions as well as in conditions
of adoptive dendritic cell transfer in immunotherapy.

text: Persistent homology is an algebraic tool for measuring topological features
of shapes and functions. It casts the multi-scale organization we frequently observe
in nature into a mathematical formalism. Here we give a record of the short history
of persistent homology and present its basic concepts. Besides the mathematics
we focus on algorithms and mention the various connections to applications, including
to biomolecules, biological networks, data analysis, and geometric modeling.

text: 'While genome-wide gene expression data are generated at an increasing rate,
the repertoire of approaches for pattern discovery in these data is still limited.
Identifying subtle patterns of interest in large amounts of data (tens of thousands
of profiles) associated with a certain level of noise remains a challenge. A microarray
time series was recently generated to study the transcriptional program of the
mouse segmentation clock, a biological oscillator associated with the periodic
formation of the segments of the body axis. A method related to Fourier analysis,
the Lomb-Scargle periodogram, was used to detect periodic profiles in the dataset,
leading to the identification of a novel set of cyclic genes associated with the
segmentation clock. Here, we applied to the same microarray time series dataset
four distinct mathematical methods to identify significant patterns in gene expression
profiles. These methods are called: Phase consistency, Address reduction, Cyclohedron
test and Stable persistence, and are based on different conceptual frameworks
that are either hypothesis- or data-driven. Some of the methods, unlike Fourier
transforms, are not dependent on the assumption of periodicity of the pattern
of interest. Remarkably, these methods identified blindly the expression profiles
of known cyclic genes as the most significant patterns in the dataset. Many candidate
genes predicted by more than one approach appeared to be true positive cyclic
genes and will be of particular interest for future research. In addition, these
methods predicted novel candidate cyclic genes that were consistent with previous
biological knowledge and experimental validation in mouse embryos. Our results
demonstrate the utility of these novel pattern detection strategies, notably for
detection of periodic profiles, and suggest that combining several distinct mathematical
approaches to analyze microarray datasets is a valuable strategy for identifying
genes that exhibit novel, interesting transcriptional patterns.'

text: The Reeb graph is a useful tool in visualizing real-valued data obtained from
computational simulations of physical processes. We characterize the evolution
of the Reeb graph of a time-varying continuous function defined in three-dimensional
space. We show how to maintain the Reeb graph over time and compress the entire
sequence of Reeb graphs into a single, partially persistent data structure, and
augment this data structure with Betti numbers to describe the topology of level
sets and with path seeds to assist in the fast extraction of level sets for visualization.

text: There have been several attempts to build a unified framework for macroecological
patterns. However, these have mostly been based either on questionable assumptions
or have had to be parameterized to obtain realistic predictions. Here, we propose
a new model explicitly considering patterns of aggregated species distributions
on multiple spatial scales, the property which lies behind all spatial macroecological
patterns, using the idea we term ‘generalized fractals’. Species’ spatial distributions
were modelled by a random hierarchical process in which the original ‘habitat’
patches were randomly replaced by sets of smaller patches nested within them,
and the statistical properties of modelled species assemblages were compared with
macroecological patterns in observed bird data. Without parameterization based
on observed patterns, this simple model predicts realistic patterns of species
abundance, distribution and diversity, including fractal-like spatial distributions,
the frequency distribution of species occupancies/abundances and the species–area
relationship. Although observed macroecological patterns may differ in some quantitative
properties, our concept of random hierarchical aggregation can be considered as
an appropriate null model of fundamental macroecological patterns which can potentially
be modified to accommodate ecologically important variables.

text: The zyxin-related LPP protein is localized at focal adhesions and cell-cell
contacts and is involved in the regulation of smooth muscle cell migration. A
known interaction partner of LPP in human is the tumor suppressor protein SCRIB.
Knocking down scrib expression c uring zebrafish embryonic development results
in defects of convergence and extension (C&E) movements, which occur during
gastrulation and mediate elongation of the anterior-posterior body axis. Mediolateral
cell polarization underlying C&E is regulated by a noncanonical Writ signaling
pathway constituting the vertebrate planar cell polarity (PCP) pathway. Here,
we investigated the role of Lpp during early zebrafish development. We show that
morpholino knockdown of Ipp results in defects of C&E, phenocopying noncanonical
Wnt signaling mutants. Time-lapse analysis associates the defective dorsal convergence
movements with a reduced ability to migrate along straight paths. In addition,
expression of Lpp is significantly reduced in Wnt11 morphants and in embryos overexpressing
Wnt11 or a dominant-negative form of Rho kinase 2, which is a downstream effector
of Wnt11, Suggesting that Lpp expression is dependent on noncanonical Wnt signaling.
Finally, we demonstrate that Lpp interacts with the PCP protein Scrib in zebrafish,
and that Lpp and Scrib cooperate for the mediation of C&E. (C) 2008 Elsevier

text: This study provides direct functional evidence that differential adhesion,
measurable as quantitative differences in tissue surface tension, influences spatial
positioning between zebrafish germ layer tissues. We show that embryonic ectodermal
and mesendodermal tissues generated by mRNA-overexpression behave on long-time
scales like immiscible fluids. When mixed in hanging drop culture, their cells
segregate into discrete phases with ectoderm adopting an internal position relative
to the mesendoderm. The position adopted directly correlates with differences
in tissue surface tension. We also show that germ layer tissues from untreated
embryos, when extirpated and placed in culture, adopt a configuration similar
to those of their mRNA-overexpressing counterparts. Down-regulating E-cadherin
expression in the ectoderm leads to reduced surface tension and results in phase
reversal with E-cadherin-depleted ectoderm cells now adopting an external position
relative to the mesendoderm. These results show that in vitro cell sorting of
zebrafish mesendoderm and ectoderm tissues is specified by tissue interfacial
tensions. We perform a mathematical analysis indicating that tissue interfacial
tension between actively motile cells contributes to the spatial organization
and dynamics of these zebrafish germ layers in vivo.

text: Handedness of the vertebrate body plan critically depends on transient embryonic
structures/ organs that generate cilia-dependent leftward fluid flow within constrained
extracellular environments. Although the function of ciliated organs in laterality
determination has been extensively studied, how they are formed during embryogenesis
is still poorly understood. Here we show that Kupffer's vesicle (KV), the zebrafish
organ of laterality, arises from a surface epithelium previously thought to adopt
exclusively extra-embryonic fates. Live multi-photon confocal imaging reveals
that surface epithelial cells undergo Nodal/TGF beta signalling-dependent ingression
at the dorsal germ ring margin prior to gastrulation, to give rise to dorsal forerunner
cells (DFCs), the precursors of KV. DFCs then migrate attached to the overlying
surface epithelium and rearrange into rosette-like epithelial structures at the
end of gastrulation. During early somitogenesis, these epithelial rosettes coalesce
into a single rosette that differentiates into the KV with a ciliated lumen at
its apical centre. Our results provide novel insights into the morphogenetic transformations
that shape the laterality organ in zebrafish and suggest a conserved progenitor
role of the surface epithelium during laterality organ formation in vertebrates.

text: Understanding the factors that direct tissue organization during development
is one of the most fundamental goals in developmental biology. Various hypotheses
explain cell sorting and tissue organization on the basis of the adhesive and
mechanical properties of the constituent cells(1). However, validating these hypotheses
has been difficult due to the lack of appropriate tools to measure these parameters.
Here we use atomic force microscopy ( AFM) to quantify the adhesive and mechanical
properties of individual ectoderm, mesoderm and endoderm progenitor cells from
gastrulating zebrafish embryos. Combining these data with tissue self-assembly
in vitro and the sorting behaviour of progenitors in vivo, we have shown that
differential actomyosin-dependent cell-cortex tension, regulated by Nodal/ TGF
beta-signalling ( transforming growth factor beta), constitutes a key factor that
directs progenitor-cell sorting. These results demonstrate a previously unrecognized
role for Nodal-controlled cell-cortex tension in germ-layer organization during
gastrulation.

text: During vertebrate gastrulation, cells forming the prechordal plate undergo
directed migration as a cohesive cluster. Recent studies revealed that E-cadherin-mediated
coherence between these cells plays an important role in effective anterior migration,
and that platelet-derived growth factor (Pdgf) appears to act as a guidance cue
in this process. However, the mechanisms underlying this process at the individual
cell level remain poorly understood. We have identified miles apart (mil) as a
suppressor of defective anterior migration of the prospective prechordal plate
in silberblick (slb)/wnt11 mutant embryos, in which E-cadherin-mediated coherence
of cell movement is reduced. mil encodes Edg5, a sphingosine-1-phosphate (S1P)
receptor belonging to a family of five G-protein-coupled receptors (S1PRs). S1P
is a lipid signalling molecule that has been implicated in regulating cytoskeletal
rearrangements, cell motility and cell adhesion in a variety of cell types. We
examined the roles of Mil in anterior migration of prechordal plate progenitor
cells and found that, in slb embryos injected with mil-MO, cells migrate with
increased motility but decreased directionality, without restoring the coherence
of cell migration. This indicates that prechordal plate progenitor cells can migrate
effectively as individuals, as well as in a coherent cluster of cells. Moreover,
we demonstrate that Mil regulates cell motility and polarisation through Pdgf
and its intracellular effecter PI3K, but modulates cell coherence independently
of the Pdgf/PI3K pathway, thus co-ordinating cell motility and coherence. These
results suggest that the net migration of prechordal plate progenitors is determined
by different parameters, including motility, persistence and coherence.

text: The controlled adhesion of cells to each other and to the extracellular matrix
is crucial for tissue development and maintenance. Numerous assays have been developed
to quantify cell adhesion. Among these, the use of atomic force microscopy (AFM)
for single-cell force spectroscopy (SCFS) has recently been established. This
assay permits the adhesion of living cells to be studied in near-physiological
conditions. This implementation of AFM allows unrivaled spatial and temporal control
of cells, as well as highly quantitative force actuation and force measurement
that is sufficiently sensitive to characterize the interaction of single molecules.
Therefore, not only overall cell adhesion but also the properties of single adhesion-receptor-ligand
interactions can be studied. Here we describe current implementations and applications
of SCFS, as well as potential pitfalls, and outline how developments will provide
insight into the forces, energetics and kinetics of cell-adhesion processes.

text: Animal body plan arises during gastrulation and organogenesis by the coordination
of inductive events and cell movements. Several signaling pathways, such as BMP,
FGF, Hedgehog, Nodal, and Wnt have well-recognized instructive roles in cell fate
specification during vertebrate embryogenesis. Growing evidence indicates that
BMP, Nodal, and FGF signaling also regulate cell movements, and that they do so
through mechanisms distinct from those that specify cell fates. Moreover, pathways
controlling cell movements can also indirectly influence cell fate specification
by regulating dimensions and relative positions of interacting tissues. The current
challenge is to delineate the molecular mechanisms via which the major signaling
pathways regulate cell fate specification and movements, and how these two processes
are coordinated to ensure normal development.

text: 'Morphogen concentration gradients provide positional information by activating
target genes in a concentration-dependent manner. Recent reports show that the
gradient of the syncytial morphogen Bicoid seems to provide precise positional
information to determine target gene domains. For secreted morphogenetic ligands,
the precision of the gradients, the signal transduction and the reliability of
target gene expression domains have not been studied. Here we investigate these
issues for the TGF-beta-type morphogen Dpp. We first studied theoretically how
cell-to-cell variability in the source, the target tissue, or both, contribute
to the variations of the gradient. Fluctuations in the source and target generate
a local maximum of precision at a finite distance to the source. We then determined
experimentally in the wing epithelium: (1) the precision of the Dpp concentration
gradient; (2) the precision of the Dpp signaling activity profile; and (3) the
precision of activation of the Dpp target gene spalt. As captured by our theoretical
description, the Dpp gradient provides positional information with a maximal precision
a few cells away from the source. This maximal precision corresponds to a positional
uncertainly of about a single cell diameter. The precision of the Dpp gradient
accounts for the precision of the spalt expression range, implying that Dpp can
act as a morphogen to coarsely determine the expression pattern of target genes.'

text: This paper presents a new approach to optimization of an energy-constrained
modulation scheme for wireless sensor networks by taking advantage of a novel
bio-inspired optimization algorithm. The algorithm is inspired by Wrightpsilas
shifting balance theory (SBT) of evolution in population genetics. The total energy
consumption of an energy-constrained modulation scheme is minimized by using the
new SBT-based optimization algorithm. The results obtained by this new algorithm
are compared with other popular optimization algorithms. Numerical experiments
are performed to demonstrate that the SBT-based algorithm could be used as an
efficient optimizer for solving the optimization problems arising from currently
emerging energy-efficient wireless sensor networks.
