The Timothy syndrome mutation in Cav1.2 gives rise to defects in neuronal differentiation by preventing a developmental switch in channel splicing and elevating calcium signaling in differentiating cells.
Pancreatic α and β cells have different cell autonomous signatures; this explains why α but not β cells can clear infections by potentially diabetogenic viruses.

Optogenetic techniques, whereby light is used to activate neuronal cells, are quickly becoming widely used in neuroscience; but excessive exposure to light can actually silence certain types of neuronal cells.
Genome editing to insert a light-sensitive dimerization module directly into the EB1 microtubule plus end adaptor gene in human induced pluripotent stem cells enables local and acute optogenetic EB1 inactivation highlighting microtubule functions in developing neuronal growth cones.

Neuronal Ia-2 and glial Kon coordinate an injury-response insulin relay that restores glial cell populations and induces neural stem cells from glia, enabling central nervous system regeneration.
During neurotransmitter release, calcium-induced membrane insertion of the C2B domain of Synaptotagmin re-orients the bound SNARE complex which dilates the fusion pore in a mechanical lever action.
Mid-gestational exposure to maternal immune activation drives a sequence of transcriptional signatures and developmental pathology in embryonic mouse cortex, culminating in altered lamination and cellular lineage specification.
