Innate Immunity (Non-specific immunity): The body's first line of defense against pathogens, providing rapid but non-specific responses. It involves physical barriers, phagocytes, and various molecular mechanisms.
Adaptive Immunity (Specific immunity): A highly specific immune response that develops over time, characterized by memory. It involves lymphocytes (B and T cells) recognizing specific antigens.
Antigen (Ag): Any molecule capable of eliciting an immune response. It is recognized by immune receptors such as immunoglobulins and T cell receptors.
Epitope (Determinant): The specific part of an antigen recognized by immune receptors. It is a distinct molecular structure on the antigen.
Lymphocytes: White blood cells involved in adaptive immunity, including B cells (produce antibodies), T cells (mediate cellular responses), and natural killer (NK) cells (innate-like cytotoxic cells).
Hematopoiesis: The process of blood cell formation from hematopoietic stem cells, occurring mainly in the bone marrow, producing various immune cells.
