摘要: In the unperturbed state, lymphocyte plasma membrane is fluid with most constituent proteins and lipids randomly distributed free to move relative one another in plane of membrane. However, under certain conditions, contractile actinomyosin–like cytoplasmic components appear be able interact molecules influence their distribution mobility. This microfilament network may also microtubules. Multivalent ligands which bind cross-link or lipidscan induce them passively cluster into patches, following they are actively carried pole lymphocyte. some cases, ligand binding induces pinocytosis ligand-receptor complex. Some functional implications nature discussed.
