In mice, but not in humans, the bone-derived hormone osteocalcin is O-glycosylated, a post-translational modification controlling its half-life in vivo.
Skin epithelium can tolerate oncogene-expressing clones through a novel cellular mechanism of inter-clonal competition between renewing progenitors along the clone's edge and differentiating progenitors within the clone's core.
Kinesin-4 KIF21B promotes rapid reorientation of the microtubule network during formation of immunological synapse in T cells by acting as a pausing and catastrophe-inducing factor that keeps microtubules short.
Optogenetic and electrical low-frequency stimulation in the sclerotic hippocampus prevents the emergence of spontaneous focal and evoked generalized seizures in a mouse epilepsy model.
Post-acute or long-COVID is associated with bystander T-cell activation and a recurring antimicrobial resistant, bacterial ventilator-associated pneumonia.
Combination of experimental mouse models with single-cell RNA-sequencing creates a detailed map of medullary thymic epithelial cell development and identifies a transit-amplifying population as the immediate precursor to Aire-expressing mTECs.
Selective activation of FZD7 signaling with an engineered WNT mimetic promotes early developmental programs, including endodermal lineage specification, in human pluripotent stem cells.
