A novel F-actin-binding motif consisting of an α-helix hairpin from a Legionella pneumophila lysine fatty acyltransferase has the potential to be developed as an F-actin probe.
Intrinsic conformational flexibility of a solute transporter is restrained by substrates, resulting in Na+ allosterically enhancing primary substrate binding through cooperative constraints on the dynamics of the cytoplasmic inner barrier.
Developmental electrophysiological adaptations and heat-sensitive proteins, such as TRPV3, in cortical excitatory neurons help maintain stable activity levels when brain temperature rises by 2–3°C during fever.

Anatomical and behavioral characterization of inhibitory neurons in the Drosophila ventral nerve cord shows their critical, diverse roles in limb coordination.
A microglia replacement approach demonstrates that brain macrophages with patient mutations from Aicardi–Goutières syndrome, a genetic, brain predominant interferonopathy, are sufficient to drive interferon responses.
Bidirectional modulation of the activity of the synaptic protein mGluR5 alters spontaneous mouse motor behavior and produces correlated changes in co-activity patterns among direct pathway neurons in the dorsal striatum.

Developmentally-based directed differentiation from cortical progenitors sets a foundation for in vitro mechanistic and therapeutic disease modeling, and toward regenerative neuronal repopulation and circuit repair.
Upregulation of the β subunit of translation initiation factor eIF2 underlies autophagy suppression and premature aging caused by disruption of axonal transport of mitochondria.
Deep behavioral phenotyping reveals that performance readouts from single-valence conditioning are biased by baseline sex differences in exploration, and mixed-valence conditioning provides a clearer assessment of learning in both sexes.

In individuals who started antiretroviral therapy during acute HIV infection, the proliferative capacity of HIV-specific CD8+ T-cells at 24 weeks of therapy predicted the subsequent reduction in the viral reservoir.
