Lymphoid organs and immune protection
Lymphoid tissues play a vital role in adaptive immunity. Secondary lymphoid organs are involved in the spatial and temporal arrangement of immune cells, which facilitates cellular interactions and the timely production of pathogen-specific responses.
T and B lymphocytes are distributed in distinct regions of lymphoid tissues; however, these cells are not present within germinal centers (GCs). In general, GC B-cells obtain antigens from follicular…
