Growth of immunogenic skin tumors: Infiltrating leukocytesChen, HwuDauRw, 1958- January 1989 (has links)
Subpopulations of tumor infiltrating leukocytes in immunogenic skin tumors were identified with monoclonal antibodies. The tumors studied included primary UV-induced tumors and JB/MS melanomas, which survive in the host by immunosuppression of the immune response. The proportions of nucleated cells in primary UV-induced tumor cell suspensions which reacted with monoclonal antibodies were: 52% Mac-1+, 21% Lyt-1+, 13% Lyt-2+, 7% L3T4+, and 8% IL-2R+. Thus there was a high proportion of cells of the macrophage lineage in the growing UV-induced tumors. In JB/MS melanoma cell suspensions the mean proportion of macrophages was 6.4%, and total T lymphocytes (Lyt-1) averaged only 5.5%. Thus, there was little leukocytes infiltration into JB/MS melanoma, suggesting that chemotaxis was defective. The high level of macrophages and T cells in the primary UV-induced tumors indicates that chemotaxis was intact. Therefore, either the tumorcidal capacities of the macrophages and Tc were insensitive to activated macrophages and to Tc cells.

Studies on a soluble immunosuppressive factor produced by Leishmania donovani infected macrophagesFielding, Mark January 1994 (has links)
The role of a parasite-produced or -induced soluble immunosuppressor in experimental kala azar was examined. It was found that in vivo infections with Leishmania donovani in the hamster (Mesocricetus auratus) produce a soluble immunosuppressor, which appears in the serum of the host and which reduces the proliferation of responding populations of murine splenocytes in a one-way mixed leukocyte reaction (MLR). The production in vitro infections of murine splenic macrophages from C57BL/6J ($Lsh sp{ rm s}$), C57L/J ($Lsh sp{ rm R}$) and BALB/c strains, the suppressive activity was not contained in either parasite-conditioned culture medium or in parasite extracts or from macrophages which have internalized killed parasites or inert particles and it is not blocked by the action of 2-mercaptoethanol or indomethacin in the culture medium. The suppressor was found to be able to selectively inhibit or reduce the proliferation of splenocytes of both the C57BL/6J and C57LN strains in a one way MLR, with the level of suppression being significantly greater upon splenocytes of the susceptible $Lsh sp{ rm s}$ strain. The suppression was dependent upon the genotype of the macrophages present in the responding population. The suppressor was also able to significantly inhibit the processing of human serum albumin by macrophages, to reduce the number of Ia ligands on the surfaces of macrophages and the production by these cells of IL-1 upon silica stimulation. / Significant reduction was also seen in the production of IL2 and in the expression of its receptor by PHA-stimulated T cells exposed to the suppressor. Partial purification and identification of the suppressor demonstrated that the suppressive activity was present in fractions between 30 and 50 kDa in size; the suppressor was also heat labile and freeze-thaw sensitive. The suppressive molecule(s) may therefore play a significant role in the establishment and pathology of L. donovani infections.
