text: The next steps of deep space exploration are manned missions to Moon and Mars.
For safe space missions for crew members, it is important to understand the impact
of space flight on the immune system. We studied the effects of 21 days dry immersion
(DI) exposure on the transcriptomes of T cells isolated from blood samples of
eight healthy volunteers. Samples were collected 7 days before DI, at day 7, 14,
and 21 during DI, and 7 days after DI. RNA sequencing of CD3+T cells revealed
transcriptional alterations across all time points, with most changes occurring
14 days after DI exposure. At day 21, T cells showed evidence of adaptation with
a transcriptional profile resembling that of 7 days before DI. At 7 days after
DI, T cells again changed their transcriptional profile. These data suggest that
T cells adapt by rewiring their transcriptomes in response to simulated weightlessness
and that remodeling cues persist when reexposed to normal gravity.

text: Regulation of the Arp2/3 complex is required for productive nucleation of
branched actin networks. An emerging aspect of regulation is the incorporation
of subunit isoforms into the Arp2/3 complex. Specifically, both ArpC5 subunit
isoforms, ArpC5 and ArpC5L, have been reported to fine-tune nucleation activity
and branch junction stability. We have combined reverse genetics and cellular
structural biology to describe how ArpC5 and ArpC5L differentially affect cell
migration. Both define the structural stability of ArpC1 in branch junctions and,
in turn, by determining protrusion characteristics, affect protein dynamics and
actin network ultrastructure. ArpC5 isoforms also affect the positioning of members
of the Ena/Vasodilator-stimulated phosphoprotein (VASP) family of actin filament
elongators, which mediate ArpC5 isoform–specific effects on the actin assembly
level. Our results suggest that ArpC5 and Ena/VASP proteins are part of a signaling
pathway enhancing cell migration.

text: The generation of a correctly-sized cerebral cortex with all-embracing neuronal
and glial cell-type diversity critically depends on faithful radial glial progenitor
(RGP) cell proliferation/differentiation programs. Temporal RGP lineage progression
is regulated by Polycomb Repressive Complex 2 (PRC2) and loss of PRC2 activity
results in severe neurogenesis defects and microcephaly. How PRC2-dependent gene
expression instructs RGP lineage progression is unknown. Here we utilize Mosaic
Analysis with Double Markers (MADM)-based single cell technology and demonstrate
that PRC2 is not cell-autonomously required in neurogenic RGPs but rather acts
at the global tissue-wide level. Conversely, cortical astrocyte production and
maturation is cell-autonomously controlled by PRC2-dependent transcriptional regulation.
We thus reveal highly distinct and sequential PRC2 functions in RGP lineage progression
that are dependent on complex interplays between intrinsic and tissue-wide properties.
In a broader context our results imply a critical role for the genetic and cellular
niche environment in neural stem cell behavior.

text: The sculpting of germ layers during gastrulation relies on the coordinated
migration of progenitor cells, yet the cues controlling these long-range directed
movements remain largely unknown. While directional migration often relies on
a chemokine gradient generated from a localized source, we find that zebrafish
ventrolateral mesoderm is guided by a self-generated gradient of the initially
uniformly expressed and secreted protein Toddler/ELABELA/Apela. We show that the
Apelin receptor, which is specifically expressed in mesodermal cells, has a dual
role during gastrulation, acting as a scavenger receptor to generate a Toddler
gradient, and as a chemokine receptor to sense this guidance cue. Thus, we uncover
a single receptor–based self-generated gradient as the enigmatic guidance cue
that can robustly steer the directional migration of mesoderm through the complex
and continuously changing environment of the gastrulating embryo.

text: Sequence-specific oligomers with predictable folding patterns, i.e., foldamers,
provide new opportunities to mimic α-helical peptides and design inhibitors of
protein-protein interactions. One major hurdle of this strategy is to retain the
correct orientation of key side chains involved in protein surface recognition.
Here, we show that the structural plasticity of a foldamer backbone may notably
contribute to the required spatial adjustment for optimal interaction with the
protein surface. By using oligoureas as α helix mimics, we designed a foldamer/peptide
hybrid inhibitor of histone chaperone ASF1, a key regulator of chromatin dynamics.
The crystal structure of its complex with ASF1 reveals a notable plasticity of
the urea backbone, which adapts to the ASF1 surface to maintain the same binding
interface. One additional benefit of generating ASF1 ligands with nonpeptide oligourea
segments is the resistance to proteolysis in human plasma, which was highly improved
compared to the cognate α-helical peptide.

text: The blood-brain barrier is made of polarized brain endothelial cells (BECs)
phenotypically conditioned by the central nervous system (CNS). Although transport
across BECs is of paramount importance for nutrient uptake as well as ridding
the brain of waste products, the intracellular sorting mechanisms that regulate
successful receptor-mediated transcytosis in BECs remain to be elucidated. Here,
we used a synthetic multivalent system with tunable avidity to the low-density
lipoprotein receptor–related protein 1 (LRP1) to investigate the mechanisms of
transport across BECs. We used a combination of conventional and super-resolution
microscopy, both in vivo and in vitro, accompanied with biophysical modeling of
transport kinetics and membrane-bound interactions to elucidate the role of membrane-sculpting
protein syndapin-2 on fast transport via tubule formation. We show that high-avidity
cargo biases the LRP1 toward internalization associated with fast degradation,
while mid-avidity augments the formation of syndapin-2 tubular carriers promoting
a fast shuttling across.

text: Coordinated conformational transitions in oligomeric enzymatic complexes modulate
function in response to substrates and play a crucial role in enzyme inhibition
and activation. Caseinolytic protease (ClpP) is a tetradecameric complex, which
has emerged as a drug target against multiple pathogenic bacteria. Activation
of different ClpPs by inhibitors has been independently reported from drug development
efforts, but no rationale for inhibitor-induced activation has been hitherto proposed.
Using an integrated approach that includes x-ray crystallography, solid- and solution-state
nuclear magnetic resonance, molecular dynamics simulations, and isothermal titration
calorimetry, we show that the proteasome inhibitor bortezomib binds to the ClpP
active-site serine, mimicking a peptide substrate, and induces a concerted allosteric
activation of the complex. The bortezomib-activated conformation also exhibits
a higher affinity for its cognate unfoldase ClpX. We propose a universal allosteric
mechanism, where substrate binding to a single subunit locks ClpP into an active
conformation optimized for chaperone association and protein processive degradation.

text: The study of parallel ecological divergence provides important clues to the
operation of natural selection. Parallel divergence often occurs in heterogeneous
environments with different kinds of environmental gradients in different locations,
but the genomic basis underlying this process is unknown. We investigated the
genomics of rapid parallel adaptation in the marine snail Littorina saxatilis
in response to two independent environmental axes (crab-predation versus wave-action
and low-shore versus high-shore). Using pooled whole-genome resequencing, we show
that sharing of genomic regions of high differentiation between environments is
generally low but increases at smaller spatial scales. We identify different shared
genomic regions of divergence for each environmental axis and show that most of
these regions overlap with candidate chromosomal inversions. Several inversion
regions are divergent and polymorphic across many localities. We argue that chromosomal
inversions could store shared variation that fuels rapid parallel adaptation to
heterogeneous environments, possibly as balanced polymorphism shared by adaptive
gene flow.

text: Chaperonins are ubiquitous protein assemblies present in bacteria, eukaryota,
and archaea, facilitating the folding of proteins, preventing protein aggregation,
and thus participating in maintaining protein homeostasis in the cell. During
their functional cycle, they bind unfolded client proteins inside their double
ring structure and promote protein folding by closing the ring chamber in an adenosine
5′-triphosphate (ATP)–dependent manner. Although the static structures of fully
open and closed forms of chaperonins were solved by x-ray crystallography or electron
microscopy, elucidating the mechanisms of such ATP-driven molecular events requires
studying the proteins at the structural level under working conditions. We introduce
an approach that combines site-specific nuclear magnetic resonance observation
of very large proteins, enabled by advanced isotope labeling methods, with an
in situ ATP regeneration system. Using this method, we provide functional insight
into the 1-MDa large hsp60 chaperonin while processing client proteins and reveal
how nucleotide binding, hydrolysis, and release control switching between closed
and open states. While the open conformation stabilizes the unfolded state of
client proteins, the internalization of the client protein inside the chaperonin
cavity speeds up its functional cycle. This approach opens new perspectives to
study structures and mechanisms of various ATP-driven biological machineries in
the heat of action.

text: Motility is a basic feature of living microorganisms, and how it works is
often determined by environmental cues. Recent efforts have focused on developing
artificial systems that can mimic microorganisms, in particular their self-propulsion.
We report on the design and characterization of synthetic self-propelled particles
that migrate upstream, known as positive rheotaxis. This phenomenon results from
a purely physical mechanism involving the interplay between the polarity of the
particles and their alignment by a viscous torque. We show quantitative agreement
between experimental data and a simple model of an overdamped Brownian pendulum.
The model notably predicts the existence of a stagnation point in a diverging
flow. We take advantage of this property to demonstrate that our active particles
can sense and predictably organize in an imposed flow. Our colloidal system represents
an important step toward the realization of biomimetic microsystems with the ability
to sense and respond to environmental changes.
