Fv-4 is a mouse gene that dominantly confers resistance to infection by ecotropic murine leukemia virus (MuLV). We previously demonstrated that mixed radiation bone marrow chimeras containing Fv-4r-bearing BALB/c-Fv-4Wr (C4W) bone marrow and Fv-4r-bearing C3H/He (C3H) bone marrow grafted into C3H recipient mice (C4W+C3H-->C3H) were resistant to Friend(More)
An experiment was conducted to reexamine earlier observations that lymphomas could develop from lymphocytes present in nonirradiated thymuses grafted into thymectomized, fractionally (170 R, 4 doses) irradiated mice by using B10. Thy 1 congenic donor-host combinations. The results indicated that: (a) 37 of 91 thymectomized, fractionally irradiated B10. Thy(More)
Fv-4 is a mouse gene that dominantly confers resistance to infection by ecotropic murine leukemia virus (MuLV). We demonstrated previously that the Fv-4 resistant (Fv-4r) gene product, Fv-4r env antigen, is released from Fv-4r-bearing BALB/c-Fv-4Wr (C4W) mouse-derived cells into serum in vivo and binds to cells expressing surface receptors for ecotropic(More)
Immunohistochemical studies were made on the regeneration of T cells of host- and donor-type in the thymus and spleen of radiation bone marrow chimeras by using B10- and B10.BR-Thy-1 congenic mice. Both the thymic cortex and the medulla were first repopulated with thymocytes of irradiated host origin, restoring the normal histologic appearance by days 11 to(More)
The I-J determinant of membrane glycoprotein is known to be expressed exclusively on suppressor T cells (TS), which have a crucial role in the regulation of immune responses. I-J also comprises part of the soluble factor (TSF) with suppressor activity which is secreted from TS. Gene-mapping experiments have indicated that the I-J gene lies between the I-A(More)
A striking difference in radiosensitivity was noted between C3H/He (H-2k) and C57BL/6J (H-2b) strain mice when assessed by primary anti-SRBC PFC response of intact animals and primary cell-mediated lympholysis (CML) response of spleen cells to allogeneic cells in vitro, the C3H strain being more radioresistant. On the other hand, when C3H and B6 mice were(More)
Fv-4 is a mouse gene that dominantly confers resistance to infection by ecotropic murine leukemia virus (MuLV). We have demonstrated previously that bone marrow chimeras in which hematopoietic cells were replaced with cells expressing Fv-4 resistant (Fv-4r) gene product became refractory to Friend leukemia virus (FLV)-induced leukemogenesis. To induce in(More)
We established several H-2-restricted lymphocytic choriomeningitis virus (LCMV)-specific cytotoxic T cell clones from spleens of virus-primed C57BL/6 or C57BL/10 (H-2b) and B10.BR (H-2k) mice and from allogeneic C57BL/10----B10.BR and B10.BR----C57BL/10 bone marrow chimeras. Two T cell clones of H-2b origin and restricted to H-2b, 3 of H-2k origin and(More)
Bone marrow transplantation (BMT) experiments were conducted using B10.Thy 1 congenic mice to explore the nature of bone marrow-thymus interactions during thymic lymphomagenesis induced by fractionated whole-body X-irradiation (FX). BMT from normal Thy 1 congenic donors into FX-treated recipients one day after FX-treatment resulted in the suppression of(More)
