The realization of essential cellular'interactions in the immune response convokes a better understandin of the fixed and free cellular components of lymphatic tissue. Ger inal centers of lymphatic tissue have long been considered to have a funda ental role in the immune reaction, and have been suspected of being topographic regions where so e of these essential cellular inter- actions may occur. The physiological significance of these topo- graphic regions in lynphatic tissue is only now becoming clarified from recent studies of antigen localization, but the histo2enic relation of the...
