B cell activation process. Humoral immunity. T cell-dependent activation. Adaptive immunity. Vector illustration. Medical poster. Schematic diagram
T-cell dependent b-cell activation. B lymphocyte binds an antigen, receive help from a T helper, and differentiate into a plasma cell that secretes of antibodies. Receptors on surface of white blood cells. Human immune system. Vector poster
Lymphocyte B and T-cell. Cells of immune system (immune response). Vector illustration on white background. Didatic illustration.
Activation of T-cell leukocytes. T-cell encounters its cognate antigen on the surface of an infected cell. T cells direct and regulate immune responses and attack infected or cancerous cells.
T and B Cell binding to elicit a response to a T cell-dependent antigen, the B and T cells must come close together. B cell must receive two signals from the native antigen and the T cells cytokines

Steps of phagocytosis. antigen presenting cell in human immune response. Antigen-presenting cell engulf antigens and process them so that they can be recognized by lymphocytes.
