Mitogenic activity of Mycoplasma pulmonis. I. Stimulation of rat B and T lymphocytes. 1979

Y Naot, and S Merchav, and E Ben-David, and H Ginsburg

The mitogenic activity of Mycoplasma pulmonis towards both rat B and T lymphocytes has been demonstrated. The data summarized in this report show that spleen cells obtained from T X BM rats were extensively activated by M. pulmonis. Furthermore, M. pulmonis has been demonstrated to induce the development of antibody producing cells, as attested by the appearance of direct plaque forming cells against SRBC and TNP-SRBC in spleen cultures exposed to this mitogen. It was also demonstrated that rat thymus cells and a part of the lymph node T-cell population responding to either Con A or PWM, were stimulated by M. pulmonis, the response being weaker than that of rat B-cell populations. It was thus concluded that M. pulmonis activates both rat B and T lymphocytes. This mitogenic stimulation, however, is not equally exerted on both these populations, being strongly effective upon B cells and less so on T cells.

UI MeSH Term Description Entries
D008213 Lymphocyte Activation Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell

D008934 Mitogens Substances that stimulate mitosis and lymphocyte transformation. They include not only substances associated with LECTINS, but also substances from streptococci (associated with streptolysin S) and from strains of alpha-toxin-producing staphylococci.

D009174 Mycoplasma A genus of gram-negative, mostly facultatively anaerobic bacteria in the family MYCOPLASMATACEAE. The cells are bounded by a PLASMA MEMBRANE and lack a true CELL WALL. Its organisms are pathogens found on the MUCOUS MEMBRANES of humans, ANIMALS, and BIRDS.

D006462 Hemolytic Plaque Technique A method to identify and enumerate cells that are synthesizing ANTIBODIES against ANTIGENS or HAPTENS conjugated to sheep RED BLOOD CELLS. The sheep red blood cells surrounding cells secreting antibody are lysed by added COMPLEMENT producing a clear zone of HEMOLYSIS.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
