Resumen: | The authors made an immunocytochemical examination of the germinal centers (GCs) of (1) lymph follicles in physiological lymph nodes and (2) extra-nodal tissues of divergent diseases including thyroid disorders, rheumatoid arthritis, Warthin's tumor and Kimura's disease (Eosinophilic lymphfolliculoid granuloma). In these germinal centers, the presence of immunoglobulins (IgG and IgM), early acting complement components (Clq, C4, C3c,C3d), receptors for C3b and C3d and dendritic reticulum cell-l was demonstrated in lace-like network patterns which were proven electron-microscopically to coincide with the surface of follicular dendritic cells. IgE was distributed in a lace-like pattern in the GCs of proliferating follicles of Kimura's disease, in which the lysis of follicles was frequently observed. This lysis appeared to be related to the presence of complement components. In the germinal centers of extra-nodal tissues, including the thyroid tissues accompanying the lymph follicles, rheumatoid arthritis synovial tissues as well as Warthin's tumors, thyroglobulin, rheumatoid factor and salivary amylase were detected as specific antigens, occurring in lacelike patterns. It is possible that follicular dendritic cells may play a role in the genesis of GCs and be responsible for the immune response through C3 receptors. |
