text: During apoptosis, caspases degrade 8 out of ~30 nucleoporins to irreversibly
demolish the nuclear pore complex. However, for poorly understood reasons, caspases
are also activated during cell differentiation. Here, we show that sublethal activation
of caspases during myogenesis results in the transient proteolysis of four peripheral
Nups and one transmembrane Nup. ‘Trimmed’ NPCs become nuclear export-defective,
and we identified in an unbiased manner several classes of cytoplasmic, plasma
membrane, and mitochondrial proteins that rapidly accumulate in the nucleus. NPC
trimming by non-apoptotic caspases was also observed in neurogenesis and endoplasmic
reticulum stress. Our results suggest that caspases can reversibly modulate nuclear
transport activity, which allows them to function as agents of cell differentiation
and adaptation at sublethal levels.

text: Although budding yeast has been extensively used as a model organism for studying
organelle functions and intracellular vesicle trafficking, whether it possesses
an independent endocytic early/sorting compartment that sorts endocytic cargos
to the endo-lysosomal pathway or the recycling pathway has long been unclear.
The structure and properties of the endocytic early/sorting compartment differ
significantly between organisms; in plant cells, the trans-Golgi network (TGN)
serves this role, whereas in mammalian cells a separate intracellular structure
performs this function. The yeast syntaxin homolog Tlg2p, widely localizing to
the TGN and endosomal compartments, is presumed to act as a Q-SNARE for endocytic
vesicles, but which compartment is the direct target for endocytic vesicles remained
unanswered. Here we demonstrate by high-speed and high-resolution 4D imaging of
fluorescently labeled endocytic cargos that the Tlg2p-residing compartment within
the TGN functions as the early/sorting compartment. After arriving here, endocytic
cargos are recycled to the plasma membrane or transported to the yeast Rab5-residing
endosomal compartment through the pathway requiring the clathrin adaptors GGAs.
Interestingly, Gga2p predominantly localizes at the Tlg2p-residing compartment,
and the deletion of GGAs has little effect on another TGN region where Sec7p is
present but suppresses dynamics of the Tlg2-residing early/sorting compartment,
indicating that the Tlg2p- and Sec7p-residing regions are discrete entities in
the mutant. Thus, the Tlg2p-residing region seems to serve as an early/sorting
compartment and function independently of the Sec7p-residing region within the
TGN.

text: Predicting function from sequence is a central problem of biology. Currently,
this is possible only locally in a narrow mutational neighborhood around a wildtype
sequence rather than globally from any sequence. Using random mutant libraries,
we developed a biophysical model that accounts for multiple features of σ70 binding
bacterial promoters to predict constitutive gene expression levels from any sequence.
We experimentally and theoretically estimated that 10–20% of random sequences
lead to expression and ~80% of non-expressing sequences are one mutation away
from a functional promoter. The potential for generating expression from random
sequences is so pervasive that selection acts against σ70-RNA polymerase binding
sites even within inter-genic, promoter-containing regions. This pervasiveness
of σ70-binding sites implies that emergence of promoters is not the limiting step
in gene regulatory evolution. Ultimately, the inclusion of novel features of promoter
function into a mechanistic model enabled not only more accurate predictions of
gene expression levels, but also identified that promoters evolve more rapidly
than previously thought.

text: Elevation of soluble wild-type (WT) tau occurs in synaptic compartments in
Alzheimer’s disease. We addressed whether tau elevation affects synaptic transmission
at the calyx of Held in slices from mice brainstem. Whole-cell loading of WT human
tau (h-tau) in presynaptic terminals at 10–20 µM caused microtubule (MT) assembly
and activity-dependent rundown of excitatory neurotransmission. Capacitance measurements
revealed that the primary target of WT h-tau is vesicle endocytosis. Blocking
MT assembly using nocodazole prevented tau-induced impairments of endocytosis
and neurotransmission. Immunofluorescence imaging analyses revealed that MT assembly
by WT h-tau loading was associated with an increased MT-bound fraction of the
endocytic protein dynamin. A synthetic dodecapeptide corresponding to dynamin
1-pleckstrin-homology domain inhibited MT-dynamin interaction and rescued tau-induced
impairments of endocytosis and neurotransmission. We conclude that elevation of
presynaptic WT tau induces de novo assembly of MTs, thereby sequestering free
dynamins. As a result, endocytosis and subsequent vesicle replenishment are impaired,
causing activity-dependent rundown of neurotransmission.

text: A key attribute of persistent or recurring bacterial infections is the ability
of the pathogen to evade the host’s immune response. Many Enterobacteriaceae express
type 1 pili, a pre-adapted virulence trait, to invade host epithelial cells and
establish persistent infections. However, the molecular mechanisms and strategies
by which bacteria actively circumvent the immune response of the host remain poorly
understood. Here, we identified CD14, the major co-receptor for lipopolysaccharide
detection, on mouse dendritic cells (DCs) as a binding partner of FimH, the protein
located at the tip of the type 1 pilus of Escherichia coli. The FimH amino acids
involved in CD14 binding are highly conserved across pathogenic and non-pathogenic
strains. Binding of the pathogenic strain CFT073 to CD14 reduced DC migration
by overactivation of integrins and blunted expression of co-stimulatory molecules
by overactivating the NFAT (nuclear factor of activated T-cells) pathway, both
rate-limiting factors of T cell activation. This response was binary at the single-cell
level, but averaged in larger populations exposed to both piliated and non-piliated
pathogens, presumably via the exchange of immunomodulatory cytokines. While defining
an active molecular mechanism of immune evasion by pathogens, the interaction
between FimH and CD14 represents a potential target to interfere with persistent
and recurrent infections, such as urinary tract infections or Crohn’s disease.

text: 'Polygenic adaptation is thought to be ubiquitous, yet remains poorly understood.
Here, we model this process analytically, in the plausible setting of a highly
polygenic, quantitative trait that experiences a sudden shift in the fitness optimum.
We show how the mean phenotype changes over time, depending on the effect sizes
of loci that contribute to variance in the trait, and characterize the allele
dynamics at these loci. Notably, we describe the two phases of the allele dynamics:
The first is a rapid phase, in which directional selection introduces small frequency
differences between alleles whose effects are aligned with or opposed to the shift,
ultimately leading to small differences in their probability of fixation during
a second, longer phase, governed by stabilizing selection. As we discuss, key
results should hold in more general settings and have important implications for
efforts to identify the genetic basis of adaptation in humans and other species.'

text: To understand the function of neuronal circuits, it is crucial to disentangle
the connectivity patterns within the network. However, most tools currently used
to explore connectivity have low throughput, low selectivity, or limited accessibility.
Here, we report the development of an improved packaging system for the production
of the highly neurotropic RVdGenvA-CVS-N2c rabies viral vectors, yielding titers
orders of magnitude higher with no background contamination, at a fraction of
the production time, while preserving the efficiency of transsynaptic labeling.
Along with the production pipeline, we developed suites of ‘starter’ AAV and bicistronic
RVdG-CVS-N2c vectors, enabling retrograde labeling from a wide range of neuronal
populations, tailored for diverse experimental requirements. We demonstrate the
power and flexibility of the new system by uncovering hidden local and distal
inhibitory connections in the mouse hippocampal formation and by imaging the functional
properties of a cortical microcircuit across weeks. Our novel production pipeline
provides a convenient approach to generate new rabies vectors, while our toolkit
flexibly and efficiently expands the current capacity to label, manipulate and
image the neuronal activity of interconnected neuronal circuits in vitro and in
vivo.

text: Together, copy-number and point mutations form the basis for most evolutionary
novelty, through the process of gene duplication and divergence. While a plethora
of genomic data reveals the long-term fate of diverging coding sequences and their
cis-regulatory elements, little is known about the early dynamics around the duplication
event itself. In microorganisms, selection for increased gene expression often
drives the expansion of gene copy-number mutations, which serves as a crude adaptation,
prior to divergence through refining point mutations. Using a simple synthetic
genetic reporter system that can distinguish between copy-number and point mutations,
we study their early and transient adaptive dynamics in real time in Escherichia
coli. We find two qualitatively different routes of adaptation, depending on the
level of functional improvement needed. In conditions of high gene expression
demand, the two mutation types occur as a combination. However, under low gene
expression demand, copy-number and point mutations are mutually exclusive; here,
owing to their higher frequency, adaptation is dominated by copy-number mutations,
in a process we term amplification hindrance. Ultimately, due to high reversal
rates and pleiotropic cost, copy-number mutations may not only serve as a crude
and transient adaptation, but also constrain sequence divergence over evolutionary
time scales.

text: Peptidoglycan is an essential component of the bacterial cell envelope that
surrounds the cytoplasmic membrane to protect the cell from osmotic lysis. Important
antibiotics such as β-lactams and glycopeptides target peptidoglycan biosynthesis.
Class A penicillin-binding proteins (PBPs) are bifunctional membrane-bound peptidoglycan
synthases that polymerize glycan chains and connect adjacent stem peptides by
transpeptidation. How these enzymes work in their physiological membrane environment
is poorly understood. Here, we developed a novel Förster resonance energy transfer-based
assay to follow in real time both reactions of class A PBPs reconstituted in liposomes
or supported lipid bilayers and applied this assay with PBP1B homologues from
Escherichia coli, Pseudomonas aeruginosa, and Acinetobacter baumannii in the presence
or absence of their cognate lipoprotein activator. Our assay will allow unravelling
the mechanisms of peptidoglycan synthesis in a lipid-bilayer environment and can
be further developed to be used for high-throughput screening for new antimicrobials.

text: The synaptic connection from medial habenula (MHb) to interpeduncular nucleus
(IPN) is critical for emotion-related behaviors and uniquely expresses R-type
Ca2+ channels (Cav2.3) and auxiliary GABAB receptor (GBR) subunits, the K+-channel
tetramerization domain-containing proteins (KCTDs). Activation of GBRs facilitates
or inhibits transmitter release from MHb terminals depending on the IPN subnucleus,
but the role of KCTDs is unknown. We therefore examined the localization and function
of Cav2.3, GBRs, and KCTDs in this pathway in mice. We show in heterologous cells
that KCTD8 and KCTD12b directly bind to Cav2.3 and that KCTD8 potentiates Cav2.3
currents in the absence of GBRs. In the rostral IPN, KCTD8, KCTD12b, and Cav2.3
co-localize at the presynaptic active zone. Genetic deletion indicated a bidirectional
modulation of Cav2.3-mediated release by these KCTDs with a compensatory increase
of KCTD8 in the active zone in KCTD12b-deficient mice. The interaction of Cav2.3
with KCTDs therefore scales synaptic strength independent of GBR activation.

text: The ubiquitous Ca2+ sensor calmodulin (CaM) binds and regulates many proteins,
including ion channels, CaM kinases, and calcineurin, according to Ca2+-CaM levels.
What regulates neuronal CaM levels, is, however, unclear. CaM-binding transcription
activators (CAMTAs) are ancient proteins expressed broadly in nervous systems
and whose loss confers pleiotropic behavioral defects in flies, mice, and humans.
Using Caenorhabditis elegans and Drosophila, we show that CAMTAs control neuronal
CaM levels. The behavioral and neuronal Ca2+ signaling defects in mutants lacking
camt-1, the sole C. elegans CAMTA, can be rescued by supplementing neuronal CaM.
CAMT-1 binds multiple sites in the CaM promoter and deleting these sites phenocopies
camt-1. Our data suggest CAMTAs mediate a conserved and general mechanism that
controls neuronal CaM levels, thereby regulating Ca2+ signaling, physiology, and
behavior.

text: Synaptic transmission, connectivity, and dendritic morphology mature in parallel
during brain development and are often disrupted in neurodevelopmental disorders.
Yet how these changes influence the neuronal computations necessary for normal
brain function are not well understood. To identify cellular mechanisms underlying
the maturation of synaptic integration in interneurons, we combined patch-clamp
recordings of excitatory inputs in mouse cerebellar stellate cells (SCs), three-dimensional
reconstruction of SC morphology with excitatory synapse location, and biophysical
modeling. We found that postnatal maturation of postsynaptic strength was homogeneously
reduced along the somatodendritic axis, but dendritic integration was always sublinear.
However, dendritic branching increased without changes in synapse density, leading
to a substantial gain in distal inputs. Thus, changes in synapse distribution,
rather than dendrite cable properties, are the dominant mechanism underlying the
maturation of neuronal computation. These mechanisms favor the emergence of a
spatially compartmentalized two-stage integration model promoting location-dependent
integration within dendritic subunits.

text: Cell division orientation is thought to result from a competition between
cell geometry and polarity domains controlling the position of the mitotic spindle
during mitosis. Depending on the level of cell shape anisotropy or the strength
of the polarity domain, one dominates the other and determines the orientation
of the spindle. Whether and how such competition is also at work to determine
unequal cell division (UCD), producing daughter cells of different size, remains
unclear. Here, we show that cell geometry and polarity domains cooperate, rather
than compete, in positioning the cleavage plane during UCDs in early ascidian
embryos. We found that the UCDs and their orientation at the ascidian third cleavage
rely on the spindle tilting in an anisotropic cell shape, and cortical polarity
domains exerting different effects on spindle astral microtubules. By systematically
varying mitotic cell shape, we could modulate the effect of attractive and repulsive
polarity domains and consequently generate predicted daughter cell size asymmetries
and position. We therefore propose that the spindle position during UCD is set
by the combined activities of cell geometry and polarity domains, where cell geometry
modulates the effect of cortical polarity domain(s).

text: Evolutionary adaptation is a major source of antibiotic resistance in bacterial
pathogens. Evolution-informed therapy aims to constrain resistance by accounting
for bacterial evolvability. Sequential treatments with antibiotics that target
different bacterial processes were previously shown to limit adaptation through
genetic resistance trade-offs and negative hysteresis. Treatment with homogeneous
sets of antibiotics is generally viewed to be disadvantageous, as it should rapidly
lead to cross-resistance. We here challenged this assumption by determining the
evolutionary response of Pseudomonas aeruginosa to experimental sequential treatments
involving both heterogenous and homogeneous antibiotic sets. To our surprise,
we found that fast switching between only β-lactam antibiotics resulted in increased
extinction of bacterial populations. We demonstrate that extinction is favored
by low rates of spontaneous resistance emergence and low levels of spontaneous
cross-resistance among the antibiotics in sequence. The uncovered principles may
help to guide the optimized use of available antibiotics in highly potent, evolution-informed
treatment designs.

text: 'The developmental strategies used by progenitor cells to endure a safe journey
from their induction place towards the site of terminal differentiation are still
poorly understood. Here we uncovered a progenitor cell allocation mechanism that
stems from an incomplete process of epithelial delamination that allows progenitors
to coordinate their movement with adjacent extra-embryonic tissues. Progenitors
of the zebrafish laterality organ originate from the surface epithelial enveloping
layer by an apical constriction process of cell delamination. During this process,
progenitors retain long-term apical contacts that enable the epithelial layer
to pull a subset of progenitors along their way towards the vegetal pole. The
remaining delaminated progenitors follow apically-attached progenitors’ movement
by a co-attraction mechanism, avoiding sequestration by the adjacent endoderm,
ensuring their fate and collective allocation at the differentiation site. Thus,
we reveal that incomplete delamination serves as a cellular platform for coordinated
tissue movements during development. Impact Statement: Incomplete delamination
serves as a cellular platform for coordinated tissue movements during development,
guiding newly formed progenitor cell groups to the differentiation site.'

text: Mechanistic modeling in neuroscience aims to explain observed phenomena in
terms of underlying causes. However, determining which model parameters agree
with complex and stochastic neural data presents a significant challenge. We address
this challenge with a machine learning tool which uses deep neural density estimators—trained
using model simulations—to carry out Bayesian inference and retrieve the full
space of parameters compatible with raw data or selected data features. Our method
is scalable in parameters and data features and can rapidly analyze new data after
initial training. We demonstrate the power and flexibility of our approach on
receptive fields, ion channels, and Hodgkin–Huxley models. We also characterize
the space of circuit configurations giving rise to rhythmic activity in the crustacean
stomatogastric ganglion, and use these results to derive hypotheses for underlying
compensation mechanisms. Our approach will help close the gap between data-driven
and theory-driven models of neural dynamics.

text: In plants, clathrin mediated endocytosis (CME) represents the major route
for cargo internalisation from the cell surface. It has been assumed to operate
in an evolutionary conserved manner as in yeast and animals. Here we report characterisation
of ultrastructure, dynamics and mechanisms of plant CME as allowed by our advancement
in electron microscopy and quantitative live imaging techniques. Arabidopsis CME
appears to follow the constant curvature model and the bona fide CME population
generates vesicles of a predominantly hexagonal-basket type; larger and with faster
kinetics than in other models. Contrary to the existing paradigm, actin is dispensable
for CME events at the plasma membrane but plays a unique role in collecting endocytic
vesicles, sorting of internalised cargos and directional endosome movement that
itself actively promote CME events. Internalized vesicles display a strongly delayed
and sequential uncoating. These unique features highlight the independent evolution
of the plant CME mechanism during the autonomous rise of multicellularity in eukaryotes.

text: Cytosine methylation regulates essential genome functions across eukaryotes,
but the fundamental question of whether nucleosomal or naked DNA is the preferred
substrate of plant and animal methyltransferases remains unresolved. Here, we
show that genetic inactivation of a single DDM1/Lsh family nucleosome remodeler
biases methylation toward inter-nucleosomal linker DNA in Arabidopsis thaliana
and mouse. We find that DDM1 enables methylation of DNA bound to the nucleosome,
suggesting that nucleosome-free DNA is the preferred substrate of eukaryotic methyltransferases
in vivo. Furthermore, we show that simultaneous mutation of DDM1 and linker histone
H1 in Arabidopsis reproduces the strong linker-specific methylation patterns of
species that diverged from flowering plants and animals over a billion years ago.
Our results indicate that in the absence of remodeling, nucleosomes are strong
barriers to DNA methyltransferases. Linker-specific methylation can evolve simply
by breaking the connection between nucleosome remodeling and DNA methylation.
