Overview: Diffuse lymphoid tissue
Diffuse lymphoid tissue consists of scattered immune cells (lymphocytes and macrophages) that monitor the tissue fluid around them for the presence of foreign antigens. Antigen detection initiates an adaptive immune response as well as recruitment of additional B and T lymphocytes, leading to the formation of lymphoid nodules, discrete clusters of lymphocytes in the lamina propria.
