Excitatory synapses that occur further away from the postsynaptic cell soma exhibit greater neurotransmitter release probability, which appears to improve signal transfer fidelity for high-frequency afferent firing.
A molecular atlas of the chick retina provides a comprehensive classification and characterization of 136 cell types, yielding novel insights into retinal structure, function, development, and evolution.
The mechanism underlying Shprintzen–Goldberg syndrome is solved and reveals that missense mutations in the transcriptional repressor SKI abolish ligand-induced SKI degradation, which results in attenuation of TGF-β transcriptional responses.
The first-in-class kinase inhibitor, Ibrutinib, destabilizes its autoinhibited Bruton’s tyrosine kinase (BTK) target, and a remote resistance mutation causes global structural changes that activate BTK catalytic activity.
Asymmetric forward and backward swimming speeds reveal that the rotational bias, and not reversal frequencies, is an appropriate measure of chemotaxis signaling in Helicobacter pylori..
Although Rad51 is the central protein involved in recombinational DNA repair, multiple auxiliary factors potentiate its activity by binding to a single, evolutionarily conserved motif.
In mice, but not in humans, the bone-derived hormone osteocalcin is O-glycosylated, a post-translational modification controlling its half-life in vivo.
A combination of animal models reveal how the molecular mechanisms of exosome secretion (RalA/B-dependent) are linked to their cargo content and their function in breast cancer pre-metastatic niche formation.
