The B-cell receptor includes both CD79 and the immunoglobulin. The plasma membrane of a B cell is indicated by the green phospholipids. The B cell receptor extends both outside the cell (above the plasma membrane) and inside the cell (below the membrane).The B-cell receptor or BCR is a transmembrane receptor protein located on the outer surface of B-cells.he plasma membrane of a B cell is indicated by the green phospholipids.

Purinergic receptors, also known as purinoceptors, are a family of plasma membrane molecules that are found in almost all mammalian tissues. Broadly, purinergic receptors and signaling have been implicated in learning and memory, locomotor and feeding behavior, and sleep.he term purinergic receptor was originally introduced to illustrate specific classes of membrane receptors that mediate relaxation of gut smooth muscle as a response to the release of ATP or adenosine. P2 receptors have further been divided into five subclasses: P2X, P2Y, P2Z, P2U, and P2T.
