the antigen must bind to the receptor
The function of an antigen-presenting cell depends on the presence of major histocompatibility complex (MHC) molecules, which provide a platform for presenting antigens to T cells. Additionally, the presence of co-stimulatory molecules is crucial for activating T cells and initiating an immune response.
The O antigen is not an antigen that may be found on the surface of an erythrocyte. A and B antigens are present in the ABO blood group system, while the Rh antigen is part of the Rh blood group system. O blood type individuals lack A and B antigens on their red blood cells.
An antigen is a substance that can invoke an immune response. While an antibody is the immune system's response to an antigen. Antibodies, act by directly neutralizing the antigen and/or bind to the antigen and signaling marcophages to phagocytose the antigen.
An antigen is a protein made in response to a specific antigen.
