چکیده

LP-BM5 retrovirus complex-infected C57BL/6 mice develop immunodeficiency, somewhat analogous to AIDS, termed murine AIDS (MAIDS). After secondary stimulation with syngeneic B-cell lymphomas from LP-BM5-infected mice, C57BL/6 mice produced vigorous CD8+ cytotoxic T lymphocytes specific for MAIDS-associated tumors. An anti-LP-BM5 specificity was suggested because spleen and lymph node cells from LP-BM5-infected mice served as target cells in competition assays, and cells from LP-BM5, but not ecotropic, virus-infected mice functioned as secondary in vitro stimulators to generate cytotoxic T lymphocytes to MAIDS tumors.

B cells are required for induction of T cell abnormalities in a murine retrovirus-induced immunodeficiency syndrome

The role of B cells in induction of phenotypic and functional abnormalities of T cells in a murine retrovirus-induced immunodeficiency syndrome, MAIDS, was evaluated in mice depleted of mature B cells from birth with anti-IgM antibodies (mu-suppressed) and infected at 4 wk of age. Multicolor FACS analyses of CD4+ T cell subsets showed that development of phenotypic abnormalities of these cells ...

BACKGROUND Murine leukemia virus, LP-BM5, induces severe immunodeficiency with abnormal lymphoproliferation in susceptible C57BL/6 mice. In a previous study, it was shown that a Sjögren's syndrome-like systemic exocrinopathy is induced in the virus infected mice. AIMS To examine lymphocyte functions of the virus infected mice. METHODS Four-week old mice were inoculated with the virus and th...

Introduction: Multiple sclerosis (MS) has been recognized as a common neurodegenerative disease that occurs after an Auto reactive T cells against myelin antigens.  Demyelination and inflammation are the main features of this disease. The anti-inflammatory and neuroprotective roles of bone marrow-derived mesenchymal stem cells (BM-MSCs) have been considered as a suitable tre...

Circulating CD8 T Lymphocytes in Human Immunodeficiency Virus-Infected Individuals Have Impaired Function and Downmodulate CD3z, the Signaling Chain of the T-Cell Receptor Complex

Although human immunodeficiency virus (HIV)-infected subjects without acquired immunodeficiency syndrome have a high frequency of HIV-specific CD8 T lymphocytes, freshly isolated lymphocytes frequently lack detectable HIV-specific cytotoxicity. However, this effector function becomes readily apparent after overnight culture. To investigate reasons for T-cell dysfunction, we analyzed T-cell expr...

    Background & Aim: Tolerance to the semi-allogenic fetal graft by the maternal immune system is a medical enigma that has stimulated investigations for a half of century. Several hypotheses have been proposed to explain the tolerance of mother to the fetus. The successful pregnancy is proposed and proved by many scientists to be a Th2 dominant phenomenon. This hypothesis is proved in most as...
