The primary functions of immunoglobulins

Immunoglobulins are antigen-specific antibodies synthesized by B cells and secreted into the serum or lymphatic system. They serve as a crucial component of beneficial natural immune responses and play an important role in protecting the body's immune function. The main functions of immunoglobulins are: 1. Participating in antigen-antibody reactions, they can activate specific immune responses to block the entry and latency of pathogens. 2. Capturing and eliminating pathogens by binding to antigens and specifically attaching to particular pathogens, forming complexes that promote deposition of antibodies and pathogens, thereby assisting other cells in destroying infected pathogens. 3. Regenerating immune function—coagulation reactions can activate thrombin, prevent blood leakage, and promote wound healing. 4. Regulating immune responses by suppressing harmful immune reactions that damage cells, balancing immune activity, and preventing excessive responses.
