Plasma membrane of immune cell

The **plasma membrane of immune cells** functions as a dynamic, biophysical, and biochemical platform essential for immune cell signaling, antigen recognition, migration, and effector function[1][4][7]. It is composed of a lipid bilayer enriched with diverse proteins—including immune receptors (such as the T cell receptor, B cell receptor, Fc receptors), transporters, and cell adhesion molecules—that collectively orchestrate the immune response[1][4]. The membrane’s composition, fluidity, and organization modulate how immune cells sense the environment, communicate with other cells, and execute defense against pathogens or tumors. Membrane properties such as lipid rafts and tension play crucial roles in localizing signaling molecules and adjusting immune responses. While not a direct therapeutic target itself, the membrane context is critical for the activity of membrane-resident immune receptors and druggable cell surface proteins[1][4][7].
