A few circadian ‘evening’ neurons within the Drosophila brain play a key role in driving activity as well as keeping time, whereas the well-known PDF-containing morning cells are likely involved in integrating and transmitting light information.
Advances in techniques for analysing single cells and tissues have inspired an international effort to create comprehensive reference maps of all human cells - the fundamental units of life - as a basis for both understanding human health and diagnosing, monitoring and treating disease.
β-adrenergic receptors at the Golgi apparatus activate a local signaling pathway, not accessed by cell surface receptors, to drive cardiac hypertrophy and could represent a target for heart failure therapy.
Genetics, in vivo imaging, and unbiased chemical biology screens reveal that Trpv6 functions as a cellular quiescence regulator and delineates a Trpv6-mediated Ca2+ signaling pathway maintaining the quiescent state.
The substrate for evolutionary divergence does not lie in changes in neuronal cell number or targeting, but rather in sensory perception and synaptic partner choice within invariant, prepatterned neuronal processes.
