Cell biology is the discipline of biological sciences that studies the structure, physiology, growth, reproduction and death of cells. Research in cell biology uses microscopic and molecular tools and examines all cell types, from unicellular organisms such as protozoa to the specialised cells that consitutute multicellular organisms.
Targeted biologics delivery requires programming multicomponent protein nanomaterials to enable selective targeting and response to environment changes in a single unified framework. A novel protein nanoparticle platform has been designed to modulate cell-surface target specificity, cargo packaging, and pH-dependent release of encapsulated cargo, providing exciting possibilities in biologics delivery.
Ferroptosis, a cell death mechanism induced by lipid peroxidation, is pivotal in tumor suppression. A recent study shows that tumor repopulating cells evade ferroptosis and develop resistance to therapy via subverting a lipid metabolism enzyme.
Stabilization of a branch structure would intuitively suggest a direct connection between trunk and bough, but in actin filament networks, cortactin clamps the branching Arp2/3 complex to the daughter filament. This has fundamental consequences for mechanistic understanding of actin branch turnover and cortactin biology.
MSCs-exo-mediated delivery of miR-1403p ameliorates cognitive impairment in mice with SAE by HMGB1-related microglial pyroptosis and S-lactoylglutathione metabolism.

Two new landmark studies use innovative and complementary lineage tracing approaches in human cerebral organoids to reveal symmetric stem cell division and direct neurogenesis of basal radial glial cells to enable cortical growth, expansion and differentiation.
