Adaptive Immunity

The adaptive immune system is composed of highly-specialized systemic cells and processes that eliminate or prevent pathogenic growth.

The adaptive immune response is mediated by B and T cells and creates immunity memory.

T cells originate from hematopoietic stem cells in the bone marrow and undergo positive and negative selection in the thymus to mature.

A lymphocyte is a type of white blood cell in the vertebrate immune system.

Antigen presentation is a process where immune cells capture antigens and then enable their recognition by T-cells.
