Abstract

Severe combined immunodeficient (SCID) mice previously transplanted with Lewis rat hematopoietic cells (SCID mouse-Lewis rat chimeras) developed experimental autoimmune encephalomyelitis (EAE) following injection with myelin basic protein (BP)-specific Lewis rat T lymphocytes. Rat T cells did not cause EAE in non-chimeric SCID mice. Thus, in addition to BP-specific rat T cells, transplanted rat hematopoietic cells were involved in the development of EAE in SCID mice. In order to examine the role of hematopoietic rat cells in the development of EAE, chimeras were constructed in SCID mice by transplanting 40 x 106 T cell-depleted adult Lewis rat bone marrow cells. Single cell suspensions of brain, blood and spleen from chimeric mice were phenotyped by monoclonal antibody staining specific for mouse or rat cellular differentiation markers at 2 week intervals. Brain cells from chimeric mice were also evaluated for the presence of rat antigen- presenting cells (APC). Four and six weeks after hematopoietic cell transfer, mouse brain contained rat cells expressing the phenotypic markers (CD45+, CD11b/c+) of CNS antigen-presenting cells (APC). Six weeks after hematopoietic cell transfer, rat cells populating the CNS of chimeras were shown to function as APC, stimulating BP-specific Lewis rat T lymphocytes in vitro.
