The primary cilia polycystin proteins, polycystin-1 and polycystin-2, affect cilia length in the kidney collecting duct epithelia, but only polycystin-2 is required for the functional ion channel in this organelle.
Antitumor (natural killer) NK cell responses are negatively regulated by interactions between NK cells and endogenous NKG2D ligands constitutively expressed on lymph node endothelial cells and super-induced on tumor-associated endothelium.
A new approach using combination of electron microscopy (EM) and high-speed atomic force microscopy (HS-AFM) clearly demonstrates dynamics of dynamin-amphiphysin complexes during membrane constriction and fission suggesting a novel 'clusterase' model of the dynamin-mediated membrane fission.
Population output variability in a motor control system varies across levels (CPG, motor neurons, muscles) and can be ascribed to life history differences among animals and in some cases to differences between bilaterally homologous elements.
In oligodendrocyte progenitor cells, lipid metabolism and peroxisome biogenesis are regulated by the low-density lipoprotein related-receptor-1, and if disrupted, impair proper white matter development and adult repair.
