text: 'Summary: Regulatory CD4+ T cells, enriched in the CD25 pool of healthy individuals,
mediate natural tolerance and prevent autoimmune diseases. Despite their fundamental
and potential clinical significance, regulatory T (TR) cells have not yet been
incorporated in a coherent theory of the immune system. This article reviews experimental
evidence and theoretical arguments supporting a model of TR cell dynamics, uncovering
some of its most relevant biological implications. According to this model, the
persistence and expansion of TR cell populations depend strictly on specific interactions
they make with antigen-presenting cells (APCs) and conventional effector T (TE)
cells. This three-partner crossregulation imposes that TR cells feed on the specific
autoimmune activities they suppress, with implications ranging from their interactions
with other cells to their repertoire selection in the periphery and in the thymus,
and to the relationship between these cells and the innate immune system. These
implications stem from the basic prediction that the peripheral dynamics sort
the CD4+ T-cell repertoire into two subsets: a less diverse set of small clones
of autoreactive effector and regulatory cells that regulate each other’s growth,
and a more diverse set of barely autoreactive TE cell clones, whose expansion
is limited only by APC availability. It is argued that such partitioning of the
repertoire sets the ground for self–non-self discrimination. '

text: Gene expression from both parental alleles is beneficial by masking the effects
of deleterious recessive mutations and by reducing the noise in gene expression
in diploid organisms. However, a class of genes are expressed preferentially or
strictly from a single allele. The selective advantage of avoiding biallelic expression
is clear for allelic-excluded antigen receptor and odorant receptor genes, genes
undergoing X-chromosome inactivation in females and parental genomic imprinted
genes. In contrast, there is no clear biological rationale for the predominant
and stochastic monoallelic expression of cytokine genes in the immune system,
and the underlying mechanism is elusive and controversial. A clarification of
the mechanism of predominant monoallelic expression would be instrumental in better
understanding its eventual biological functional. This prompted the development
of a quantitative framework that could describe the dynamics of the pattern of
allele expression of the IL-10 gene, from which general quantitative insights
could be gained. We report that the experimental observations on these patterns
of allelic expression cannot be easily reconciled with a simple model of stochastic
transcriptional activation, in which the two alleles are, at any time, equally
competent for transcription. Instead, these observations call into action a general
model of eukaryotic transcriptional regulation according to which the locus competence
for transcription is dynamic, involving multiple, cooperative and stochastic modification
steps. In this model, the probability that an allele becomes transcriptionally
active is a function of the number of chromatin modifications that it accumulated.
On the basis of the properties of this model, we argue that predominant monoallelic
expression might have had no adaptive role, and may have evolved under indirect
selection for low frequency of expressing cells.

Directional transport of the phytohormone auxin is established primarily at the point of cellular afflux and is required for the establishment and maintenance of plant polarity. Studies in whole plants and heterologous systems indicate that PIN-FORMED (PIN) and P-glycoprotein (PGP) transport proteins mediate the cellular efflux of natural and synthetic auxins. However, aromatic anion transport resulting from PGP and PIN expression in nonplant systems was also found to lack tha high level of substrate specificity seen in planta. Furthermore, previous reports that PGP19 stabilizes PIN1 on the plasma membrane suggested that PIN-PGP interactions might regulate polar auxin efflux. Hare, we show that PGP1 and PGP19 colocalized with PIN1 in the shoot apax in Arabidopsis thaliana and with PIN1 and PIN2 in root tissues. Specific PGP-PIN interactions were seen in yeast two-hybrid and colmmunoprecipitation assays. PIN-PGP interactions appeared to enhance transport activity and, to a greater extent, substrate/inhibitor specificities when coexpressed in heterologous systems. By contrast, no interactions between PGPs and the AUXIN1 influx carrier were observed. Phenotypes of pin and pgp mutants suggest discrete functional roles in auxin transport, but pin pgp mutants exhibited phenotypes that are both additive and synergistic. These results suggest that PINs and PGPs characterize coordinated, Independent auxin transport mechanisms but also function interactively in a tissue-specific manner.

text: Polarized transport of the plant hormone auxin influences multiple growth
processes in plants and is regulated by plasma-membrane-localized efflux and uptake
carriers. The PGP (P-glycoprotein) ABC transporters (ATP-binding-cassette transporters),
PIN (pin-formed) subfamily of major facilitator proteins and members of AUX/LAX
families have been shown to independently transport auxin both in planta and in
heterologous systems. However, PIN- and PGP-mediated transport in heterologous
systems exhibits decreased substrate specificity and inhibitor-sensitivity compared
with what is seen in plants and plant cells. To determine whether PIN-PGP interactions
enhance transport specificity, we analysed interactions of the representative
auxin-transporting PGPs with PIN1 and AUX1 in planta and in heterologous systems.
Here, we provide evidence that PINs and PGPs interact and function both independently
and co-ordinately to control polar auxin transport and impart transport specificity
and directionality. These interactions take place in protein complexes stabilized
by PGPs in detergent-resistant microdomains.

endocytosis [2, 3]. In plants, endocytosis is poorly defined, and no molecular
mechanism for cargo internalization has been demonstrated so far [4, 5], although
the internalization of receptor-ligand complexes at the plant plasma membrane
has recently been shown [6]. Here we demonstrate by means of a green-to-red photoconvertible
fluorescent reporter, EosFP [7], the constitutive endocytosis of PIN auxin efflux
carriers [8] and their recycling to the plasma membrane. Using a plant clathrin-specific
antibody, we show the presence of clathrin at different stages of coated-vesicle
formation at the plasma membrane in Arabidopsis. Genetic interference with clathrin
function inhibits PIN internalization and endocytosis in general. Furthermore,
pharmacological interference with cargo recruitment into the clathrin pathway
blocks internalization of PINs and other plasma-membrane proteins. Our data demonstrate
that clathrin-dependent endocytosis is operational in plants and constitutes the
predominant pathway for the internalization of numerous plasma-membrane-resident
proteins including PIN auxin efflux carriers.

text: 'Cytokinesis ensures proper partitioning of the nucleocytoplasmic contents
into two daughter cells. It has generally been thought that cytokinesis is accomplished
differently in animals and plants because of the differences in the preparatory
phases, into the centrosomal or acentrosomal nature of the process, the presence
or absence of rigid cell walls, and on the basis of ‘outside‐in’ or ‘inside‐out’
mechanism. However, this long‐standing paradigm needs further reevaluation based
on new findings. Recent advances reveal that plant cells, similarly to animal
cells, possess astral microtubules that regulate the cell division plane. Furthermore,
endocytosis has been found to be important for cytokinesis in animal and plant
cells: vesicles containing endocytosed cargo provide material for the cell plate
formation in plants and for closure of the midbody channel in animals. Thus, although
the preparatory phases of the cell division process differ between plant and animal
cells, the later phases show similarities. We unify these findings in a model
that suggests a conserved mode of cytokinesis.'

text: The plant hormone auxin is frequently observed to be asymmetrically distributed
across adjacent cells during crucial stages of growth and development. These auxin
gradients depend on polar transport and regulate a wide variety of processes,
including embryogenesis, organogenesis, vascular tissue differentiation, root
meristem maintenance and tropic growth. Auxin can mediate such a perplexing array
of developmental processes by acting as a general trigger for the change in developmental
program in cells where it accumulates and by providing vectorial information to
the tissues by its polar intercellular flow. In recent years, a wealth of molecular
data on the mechanism of auxin transport and its regulation has been generated,
providing significant insights into the action of this versatile coordinative
signal.

text: In plants, each developmental process integrates a network of signaling events
that are regulated by different phytohormones, and interactions among hormonal
pathways are essential to modulate their effect. Continuous growth of roots results
from the postembryonic activity of cells within the root meristem that is controlled
by the coordinated action of several phytohormones, including auxin and ethylene.
Although their interaction has been studied intensively, the molecular and cellular
mechanisms underlying this interplay are unknown. We show that the effect of ethylene
on root growth is largely mediated by the regulation of the auxin biosynthesis
and transport-dependent local auxin distribution. Ethylene stimulates auxin biosynthesis
and basipetal auxin transport toward the elongation zone, where it activates a
local auxin response leading to inhibition of cell elongation. Consistently, in
mutants affected in auxin perception or basipetal auxin transport, ethylene cannot
activate the auxin response nor regulate the root growth. In addition, ethylene
modulates the transcription of several components of the auxin transport machinery.
Thus, ethylene achieves a local activation of the auxin signaling pathway and
regulates root growth by both stimulating the auxin biosynthesis and by modulating
the auxin transport machinery.

text: Polar transport of the phytohormone auxin controls numerous growth responses
in plants. Molecular characterization of auxin transport in Arabidopsis thaliana
has provided important insights into the mechanisms underlying the regulation
of auxin distribution. In particular, the control of subcellular localization
and expression of PIN-type auxin efflux components appears to be fundamental for
orchestrated distribution of the growth regulator throughout the entire plant
body. Here we describe the identification of two Arabidopsis loci, MOP2 and MOP3
(for MODULATOR OF PIN), that are involved in control of the steady-state levels
of PIN protein. Mutations in both loci result in defects in auxin distribution
and polar auxin transport, and cause phenotypes consistent with a reduction of
PIN protein levels. Genetic interaction between PIN2 and both MOP loci is suggestive
of functional cross-talk, which is further substantiated by findings demonstrating
that ectopic PIN up-regulation is compensated in the mop background. Thus, in
addition to pathways that control PIN localization and transcription, MOP2 and
MOP3 appear to be involved in fine-tuning of auxin distribution via post-transcriptional
regulation of PIN expression.

text: In plants, cell polarity and tissue patterning are connected by intercellular
flow of the phytohormone auxin, whose directional signaling depends on polar subcellular
localization of PIN auxin transport proteins. The mechanism of polar targeting
of PINs or other cargos in plants is largely unidentified, with the PINOID kinase
being the only known molecular component. Here, we identify PP2A phosphatase as
an important regulator of PIN apical-basal targeting and auxin distribution. Genetic
analysis, localization, and phosphorylation studies demonstrate that PP2A and
PINOID both partially colocalize with PINs and act antagonistically on the phosphorylation
state of their central hydrophilic loop, hence mediating PIN apical-basal polar
targeting. Thus, in plants, polar sorting by the reversible phosphorylation of
cargos allows for their conditional delivery to specific intracellular destinations.
In the case of PIN proteins, this mechanism enables switches in the direction
of intercellular auxin fluxes, which mediate differential growth, tissue patterning,
and organogenesis.

text: In Arabidopsis thaliana, lateral roots are formed from root pericycle cells
adjacent to the xylem poles. Lateral root development is regulated antagonistically
by the plant hormones auxin and cytokinin. While a great deal is known about how
auxin promotes lateral root development, the mechanism of cytokinin repression
is still unclear. Elevating cytokinin levels was observed to disrupt lateral root
initiation and the regular pattern of divisions that characterizes lateral root
development in Arabidopsis. To identify the stage of lateral root development
that is sensitive to cytokinins, we targeted the expression of the Agrobacterium
tumefaciens cytokinin biosynthesis enzyme isopentenyltransferase to either xylem-pole
pericycle cells or young lateral root primordia using GAL4-GFP enhancer trap lines.
Transactivation experiments revealed that xylem-pole pericycle cells are sensitive
to cytokinins, whereas young lateral root primordia are not. This effect is physiologically
significant because transactivation of the Arabidopsis cytokinin degrading enzyme
cytokinin oxidase 1 in lateral root founder cells results in increased lateral
root formation. We observed that cytokinins perturb the expression of PIN genes
in lateral root founder cells and prevent the formation of an auxin gradient that
is required to pattern lateral root primordia.

text: Accumulation of specific proteins at synaptic structures is essential for
synapse assembly and function, but mechanisms regulating local protein enrichment
remain poorly understood. At the neuromuscular junction (NMJ), subsynaptic nuclei
underlie motor axon terminals within extrafusal muscle fibers and are transcriptionally
distinct from neighboring nuclei. In this study, we show that expression of the
ETS transcription factor Erm is highly concentrated at subsynaptic nuclei, and
its mutation in mice leads to severe downregulation of many genes with normally
enriched subsynaptic expression. Erm mutant mice display an expansion of the muscle
central domain in which acetylcholine receptor (AChR) clusters accumulate, show
gradual fragmentation of AChR clusters, and exhibit symptoms of muscle weakness
mimicking congenital myasthenic syndrome (CMS). Together, our findings define
Erm as an upstream regulator of a transcriptional program selective to subsynaptic
nuclei at the NMJ and underscore the importance of transcriptional control of
local synaptic protein accumulation.

text: 'The maximum flow algorithm for minimizing energy functions of binary variables
has become a standard tool in computer vision. In many cases, unary costs of the
energy depend linearly on parameter lambda. In this paper we study vision applications
for which it is important to solve the maxflow problem for different lambda''s.
An example is a weighting between data and regularization terms in image segmentation
or stereo: it is desirable to vary it both during training (to learn lambda from
ground truth data) and testing (to select best lambda using high-knowledge constraints,
e.g. user input). We review algorithmic aspects of this parametric maximum flow
problem previously unknown in vision, such as the ability to compute all breakpoints
of lambda and corresponding optimal configurations infinite time. These results
allow, in particular, to minimize the ratio of some geometric functional, such
as flux of a vector field over length (or area). Previously, such functional were
tackled with shortest path techniques applicable only in 2D. We give theoretical
improvements for "PDE cuts" [5]. We present experimental results for
image segmentation, 3D reconstruction, and the cosegmentation problem.'

text: Many computer vision applications rely on the efficient optimization of challenging,
so-called non-submodular, binary pairwise MRFs. A promising graph cut based approach
for optimizing such MRFs known as "roof duality" was recently introduced
into computer vision. We study two methods which extend this approach. First,
we discuss an efficient implementation of the "probing" technique introduced
recently by Boros et al. [5]. It simplifies the MRF while preserving the global
optimum. Our code is 400-700 faster on some graphs than the implementation of
[5]. Second, we present a new technique which takes an arbitrary input labeling
and tries to improve its energy. We give theoretical characterizations of local
minima of this procedure. We applied both techniques to many applications, including
image segmentation, new view synthesis, superresolution, diagram recognition,
parameter learning, texture restoration, and image deconvolution. For several
applications we see that we are able to find the global minimum very efficiently,
and considerably outperform the original roof duality approach. In comparison
to existing techniques, such as graph cut, TRW, BP, ICM, and simulated annealing,
we nearly always find a lower energy.

text: 'Optimization techniques based on graph cuts have become a standard tool for
many vision applications. These techniques allow to minimize efficiently certain
energy functions corresponding to pairwise Markov Random Fields (MRFs). Currently,
there is an accepted view within the computer vision community that graph cuts
can only be used for optimizing a limited class of MRF energies (e.g., submodular
functions). In this survey, we review some results that show that graph cuts can
be applied to a much larger class of energy functions (in particular, nonsubmodular
functions). While these results are well-known in the optimization community,
to our knowledge they were not used in the context of computer vision and MRF
optimization. We demonstrate the relevance of these results to vision on the problem
of binary texture restoration. '

text: 'A (k, ℓ)-robust combiner for collision-resistant hash-functions is a construction
which from ℓ hash-functions constructs a hash-function which is collision-resistant
if at least k of the components are collision-resistant. One trivially gets a
(k, ℓ)-robust combiner by concatenating the output of any ℓ - k + 1 of the components,
unfortunately this is not very practical as the length of the output of the combiner
is quite large. We show that this is unavoidable as no black-box (k, ℓ)-robust
combiner whose output is significantly shorter than what can be achieved by concatenation
exists. This answers a question of Boneh and Boyen (Crypto''06). '

text: 'Many aspects of cryptographic security proofs can be seen as the proof that
a certain system (e.g. a block cipher) is indistinguishable from an ideal system
(e.g. a random permutation), for different types of distinguishers. This paper
presents a new generic approach to proving upper bounds on the information-theoretic
distinguishing advantage (from an ideal system) for a combined system, assuming
upper bounds of certain types for the component systems. For a general type of
combination operation of systems, including the XOR of functions or the cascade
of permutations, we prove two amplification theorems. The first is a product theorem,
in the spirit of XOR-lemmas: The distinguishing advantage of the combination of
two systems is at most twice the product of the individual distinguishing advantages.
This bound is optimal. The second theorem states that the combination of systems
is secure against some strong class of distinguishers, assuming only that the
components are secure against some weaker class of distinguishers. A key technical
tool of the paper is the proof of a tight two-way correspondence, previously only
known to hold in one direction, between the distinguishing advantage of two systems
and the probability of winning an appropriately defined game. © International
