Antigen-binding receptor

An antigen-binding receptor is a cellular receptor that recognizes certain antigens and participates in the body's immune response to them.

An antigen is a foreign substance that can be dangerous to the body and trigger an immune response. Antigen-binding receptors are capable of recognizing this antigen and triggering an immune response that can lead to the destruction of the antigen or its neutralization.

Antigen-binding receptors are composed of several components, including proteins that bind to antigens and signaling proteins that convey information about antigen binding into the cell. These proteins may vary depending on the cell type and the type of antigen, but they are all involved in recognizing and responding to antigen.

Antigen binding receptors (ARB or RB) are cells of the immune system that play an important role in protecting the body from infectious agents. These cells are able to bind to antigens, which allows them to detect foreign particles such as bacteria, viruses and other microorganisms.

Antigen-binding receptors are like real “professionals”, always on duty and ready to protect the body. They function as the first line of defense against infections and more. Deprived of immune plasma, some people gain immunity naturally through RSR. This means that RSBs not only have a protective function, but also serve as the basis for human immunity.

Regarding the functioning of the SSR, several key points can be mentioned here. Elements such as the MHC complex molecule (MHC, Major Histocompatibility Complex) and antigens allow the attachment of RSB in the zone of the MHC molecule. As a result, an exchange of RSB cells occurs. Direct interaction between RSBs gives them the opportunity to recognize each other. It is this mechanism that underlies the formation of antibodies by B cells and their integration into the immune system. Notably, RBP synthesis is co-regulated by immune pressure generated by other immunocompetent cells, which include various types of T cells. The amount of RBP is determined by the content of cytokines, for example, IFN-γ, IL-4, IL-5 or IL-13, as well as other factors. As a result, recognition of harmful microorganisms requires a large number of antigen-related receptors on blood cells. However, in the presence of infection, most RSB cells quickly convert into plasma cells that produce antibodies. A typical reaction resulting from an increase in the number of antibodies, as indicated by an increase in the concentration of circulating immunoglobulins. Antibodies are usually either monoclonal antibodies (play an important role in immune memory, providing a rapid response to repeated infections
