Excitatory recurrent synapses in the upper pyramidal layer of the prefrontal cortex exhibit delayed short-term facilitation, despite very high vesicular fusion probability, through synaptotagmin 7-dependent overfilling of release sites.
Drug repurposing analyses show that citalopram exerts anti-tumor effects by targeting C5aR1 on tumor-associated macrophages to enhance phagocytosis and CD8+ T cell immunity.

Mouse primary motor and somatosensory cortices contain detailed information about the many time-varying arm and paw joint angles during reaching and grasping, implying a 'low-level' role in controlling these movements.
Three newly developed biosensors demonstrate that the C-terminal tail of α-tubulin does not freely extend from the microtubule surface as widely thought, but rather is inaccessible along most microtubules in cells.

Metabolic imaging of the Drosophila mushroom body reveals distinct profiles among Kenyon cell subtypes and detects a subtle learning-associated metabolic change.
Muscle stem cells repurpose the tenogenic factor Scx to establish a muscle-specific transcriptional program that sustains stem cell expansion, migration, differentiation, fusion, self-renewal, and survival.
A multidisciplinary approach demonstrates that glycolysis orchestrates fungal morphogenesis and virulence by regulating the de novo biosynthesis of sulfur-containing amino acids, thereby establishing a novel metabolic paradigm.
Mir195 enables Ebf1-deficient hematopoietic progenitor cells to mature into B cells, suggesting some miRNA can substitute for transcription factors in differentiation.
Upregulated expression of transcription factors promoting cone identity in late-stage retinal progenitors drives development of the cone-dominant retina of 13-lined ground squirrels.
