Successful engraftment of hematopoietic stem cells requires a supportive hematopoietic stromal microenvironment (HSM). Defects in the HSM associated with aplastic anemia, myelofibrosis, or caused by intensive ionizing radiation and chemotherapy gener

Intravenous injection of 200 μg of Vi-antigen into adult mice induces a state of short-term (10–12 days) areactivity in the animals. The observed depression of the immune response is due to blockage of the immunocompetent cells and not to masking

Immune response and suppressor cell activity of CBA (H-2k) mice made tolerant to allogeneic C57B1/6 (H-2b) heart graft were studied in graft-versus-graft reaction (GvGR). Intact CBA spleen cells inhibited response of (CBA X C57B1/6)F1 cells to antige

Treatment with Vi antigen followed after 46–48 h by cyclophosphamide induces a state of specific areactivity in mice which persists through adoptive transfer. Only trace amounts of Vi antigen were found in the blood and spleen of the tolerant mice

The role of T suppressors in the regulation of the immune response toSalmonella typhi Vi-antigen was studied by comparing the immune response to this antigen in T cell deprived mice (B mice) with the immune response in intact animals. Deprivation of

A preparation of the T-antigen of virus SV-40 was isolated from an extract of golden hamster tumors by precipitation with ammonium sulfate followed by fractionation on DEAE-cellulose. Despite 100-fold purification of the preparation it contained trac

Intravenous injection to adult mice of Vi-antigen (200 microgram) induces in them the state of a short-term (10--12 days) unresponsiveness. This is due to the block of immunocompetent cells, not to masking the antibodies production by the excess of f

(CBA X C57B1/6)F1 mice immunized three times with rat erythrocytes produced antibodies both to this antigen and to autologous erythrocytes. Most of the antibodies to rat erythrocytes belonged to IgM isotype while antibodies to autologous red cells we

Comparison of immune response to Vi-antigen in thymetomized letally irradiated and reconstituted with fetal liver cells mice and in control animals revealed no difference between the two groups. The absence of enchancement of antibody formation in T

SV40 T-antigens were isolated from an extract of golden hamster tumours by precipitation with ammonium sulphate with subsequent fractionation on DEAE cellulose. The degree of purification of the preparation proved to be about 100-fold; it, however, c
