antigénprezentálást
Antigénprezentálás is a fundamental process in immunology that enables the adaptive immune system to recognize and respond to foreign invaders such as bacteria and viruses. It involves specialized cells, primarily antigen-presenting cells (APCs), which capture, process, and display fragments of these foreign substances, known as antigens, on their surface. The main types of APCs include dendritic cells, macrophages, and B cells.
Dendritic cells are particularly important as they are highly efficient at capturing antigens in peripheral tissues
The antigens are typically presented on the surface of APCs bound to molecules called major histocompatibility
This presentation of antigens by MHC molecules is crucial for the activation of T lymphocytes. Naive T
