Graft-versus-host disease (GVHD) can occur in bone marrow-transplant recipients even when donor and host are identically matched at the major histocompatibility complex. GVHD in this context presumably arises because of differences in minor histocompatibility antigens. Murine GVHD to minor histocompatibility antigens has been studied in an effort to determine whether skin is a target of the immune response in this model system. T cell-depleted marrow cells (10(7)) from B10.BR (H-2k) mice were supplemented with varying numbers of nylon wool-enriched splenic B10.BR T cells and transplanted intravenously into irradiated (1100 R) CBA (H-2k) mice. Sequential biopsies of ear skin were obtained at weekly intervals over a 7-week period. Histopathologic evaluation revealed basal cell layer vacuolization, exocytosis, and satellitosis of mononuclear cells in the epidermis. Dyskeratosis was observed only in animals receiving T cells, and proved to be the most reliable histologic parameter of disease with the number of dyskeratotic cells per linear millimeter of epidermis correlating both with severity of clinical disease and with the number of transplanted T cells. Ultrastructural examination revealed exocytosis of mononuclear cells into the epidermis where they were frequently apposed to degenerating and necrotic keratinocytes. These data indicate that the skin is an informative target organ for study of experimental GVHD to minor histocompatibility antigens.

UI	MeSH Term	Description	Entries
D008212	Lymphocyte Depletion	Immunosuppression by reduction of circulating lymphocytes or by T-cell depletion of bone marrow. The former may be accomplished in vivo by thoracic duct drainage or administration of antilymphocyte serum. The latter is performed ex vivo on bone marrow before its transplantation.	Depletion, Lymphocyte
D008807	Mice, Inbred BALB C	An inbred strain of mouse that is widely used in IMMUNOLOGY studies and cancer research.	BALB C Mice, Inbred,BALB C Mouse, Inbred,Inbred BALB C Mice,Inbred BALB C Mouse,Mice, BALB C,Mouse, BALB C,Mouse, Inbred BALB C,BALB C Mice,BALB C Mouse
D008912	Minor Histocompatibility Loci	Genetic loci responsible for the encoding of histocompatibility antigens other than those encoded by the MAJOR HISTOCOMPATIBILITY COMPLEX. The antigens encoded by these genes are often responsible for graft rejection in cases where histocompatibility has been established by standard tests. The location of some of these loci on the X and Y chromosomes explains why grafts from males to females may be rejected while grafts from females to males are accepted. In the mouse roughly 30 minor histocompatibility loci have been recognized, comprising more than 500 genes.

D001853	Bone Marrow	The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.

D004195	Disease Models, Animal	Naturally-occurring or experimentally-induced animal diseases with pathological processes analogous to human diseases.	Animal Disease Model,Animal Disease Models,Disease Model, Animal
D004817	Epidermis	The external, nonvascular layer of the skin. It is made up, from within outward, of five layers of EPITHELIUM: (1) basal layer (stratum basale epidermidis); (2) spinous layer (stratum spinosum epidermidis); (3) granular layer (stratum granulosum epidermidis); (4) clear layer (stratum lucidum epidermidis); and (5) horny layer (stratum corneum epidermidis).
D006086	Graft vs Host Disease	The clinical entity characterized by anorexia, diarrhea, loss of hair, leukopenia, thrombocytopenia, growth retardation, and eventual death brought about by the GRAFT VS HOST REACTION.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
