Antigen presentation is the process by which cells display antigen fragments on their surface, allowing T lymphocytes (T cells) to recognize and respond to them. This mechanism is crucial for initiating an adaptive immune response against pathogens or infected cells.
congrats on reading the definition of antigen presentation. now let's actually learn it.
A set of cell surface proteins essential for the immune system to recognize foreign molecules in vertebrates, playing a critical role in antigen presentation.
T Lymphocytes (T Cells): A type of white blood cell that plays a central role in cell-mediated immunity, differentiating into various types upon activation to perform specific immune functions.
The response of antigen-specific lymphocytes, including both T cells and B cells, to foreign pathogens or internal abnormalities, characterized by immunological memory and specificity
