Plasma membrane segregation during T cell activation: probing the order of domains.
T cell activation leads to a segregation of plasma membrane domains to form TCR signalling clusters and eventually immunological synapses. At these T cell activation sites signalling protein networks reside in plasma membrane regions which adopt a highly ordered physical state. Studies of reconstituted model membranes suggest that aggregation of lipid raft-favouring membrane components may trigger this lipid ordering and condensation of membrane domains in T cells. Activation-induced protein-...Expand abstract
