Figure: B cell receptors: B cell receptors are embedded in the membranes of B cells and bind a variety of antigens through their variable regions, or antibodies. The signal transduction region transfers the signal into the cell.
WebThe process starts by the molecule binding to specific receptors on the surface of the cell membrane, triggering the cell membrane to reshape, surrounding the molecule. The receptors allow this process to be specific, controlling what can enter the cell.
