Immunogenetic analysis of cellular interactions governing the recruitment of T lymphocytes and monocytes in lymphocytic choriomeningitis virus-induced immunopathology

The Lyt2+ class I major histocompatibility complex (MHC)-restricted virus-immune T cells that induce murine lymphocytic choriomeningitis (LCM) are targeted onto radiation-resistant cells in the central nervous system of virus-infected mice. The use of appropriate bone marrow radiation chimeras as LCM virus-infected, (immunosuppressed recipients for immune T-cell transfer has established that, though bone marrow-derived cells can stimulate virus-specific cytotoxic T lymphocytes (CTL) in spleen, they do not reconstitute the barrier to T-cell recruitment from blood to cerebrospinal fluid. This is true for chimeras made up to 8 months previously, even though the inflammatory monocytes and macrophages in such chimeras are all of donor bone marrow origin. Radiation-resistant cells in the spleens of these chimeras are also still able to further stimulate virus-immune CTL. There is no requirement for H-2 compatibility between virus-immune T lymphocytes and secondarily recruited monocytes, or T cells of an inappropriate specificity. The key event in LCM immunopathology may thus be localization of T cells to the antigen-presenting endothelium in brain, leading to the secretion of mediators that promote the nonspecific recruitment of monocytes and other T cells.
