WebThe tube is formed from polymerized dimers of α-tubulin and β-tubulin, two globular proteins. These proteins form long chains that comprise the microtubuleʼs walls. The assembly is slow and occurs from the plus end, which is designated by a row of β-tubulin. Disassembly can occur rapidly at the plus end. (Note the minus end has a row of α-tubulin.) WebThe BBB is formed by brain endothelial cells (BEC) lining the cerebral microvasculature, together with perivascular elements such as closely associated astrocytic end-feet processes, perivascular neurons and pericytes [6,7].Two tightly controlled pathways for molecules and cells to cross the BBB exist: (a) A transcellular pathway across the …
