Abstract:
A series of monoclonal antibodies have been used to study the distribution of T and B lymphocytes and their subsets in human spleen (5 from normal human and 2 from patients with portal hypertension). The results indicate that the T cells are mostly located in the periarterial lymphatic sheath, and in which a few B lymphocytes can be seen. The B cells are concentrated in lymphoid follicles, but also contain some T lymphocytes such as Leu 1, Leu 3a and Leu 4 positive T cells, these cells are necessary for forming of germinal center. Whereas the marginal zone, is composed of a mixture of T and B cells as well as the T_(ac) positive cells. The red pulp is composed of a mixture of T and B ceils, but the T and B cells are distributed randomly. In this report, the LN-2 monoclonal antibody is used first to study the B lymphocytes in human spleen. So far it is a unique antibody to react with nuclear membrane of B lymphocytes, the activity of LN-2 antigen do not influenced by B-5 fixation and paraffin embedding. From our data, there is no difference in staining feature and charateristic distribution between the normal human spleen and spleen of portal hypertensive patients. Although the periarterial lymphatic sheath in cases with portal hypertension seems to be narrower than the normal.
