| Abstract: | The authors have conducted electron microscopic and ultracytochemical studies of blood lymphocytes of healthy individuals containing Gall bodies (GB) which are typical for CD4+ cell subpopulation. It has been established that GB have quite a complex submicroscopic structure and together with its derivates, granules-satellites, as well as mitochondria, microfilaments, rough endoplasmic reticulum canaliculi, and Golgi complex it forms a unique active functional complex. GB show a high activity of acid phosphatase and positive reaction to glycogen. The data obtained suggest the leading role of GB in the production of cytokins and other biologically active substances. |
