Adhesion molecules are essential for the recruitment of T cells into the skin during the development of graft-vs-host skin disease (GVHSD). However, the mechanisms responsible for the regulation of expression of cutaneous adhesion molecules in this setting are still poorly understood. In this study we blocked lymphotoxin (LT) signaling in a murine model of minor histocompatibility Ag system mismatch GVHSD by using an LTbeta receptor-Ig fusion protein (LTbetaR-Ig). The recipient mice treated with control human Ig developed clinically apparent, severe skin lesions. However, none of the mice treated with LTbetaR-Ig developed clinical skin disease. The expression of ICAM-1 in cutaneous tissue was also much lower in mice treated with LTbetaR-Ig than in mice treated with human Ig. Thus, the inhibition of LT signaling via LTbetaR-Ig treatment appears to be capable of markedly ameliorating the development of GVHSD, possibly by inhibiting the expression of adhesion molecules.

UI	MeSH Term	Description	Entries
D008233	Lymphotoxin-alpha	A tumor necrosis factor family member that is released by activated LYMPHOCYTES. Soluble lymphotoxin is specific for TUMOR NECROSIS FACTOR RECEPTOR TYPE I; TUMOR NECROSIS FACTOR RECEPTOR TYPE II; and TUMOR NECROSIS FACTOR RECEPTOR SUPERFAMILY, MEMBER 14. Lymphotoxin-alpha can form a membrane-bound heterodimer with LYMPHOTOXIN-BETA that has specificity for the LYMPHOTOXIN BETA RECEPTOR.

D008810	Mice, Inbred C57BL	One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D002464	Cell Migration Inhibition	Phenomenon of cell-mediated immunity measured by in vitro inhibition of the migration or phagocytosis of antigen-stimulated LEUKOCYTES or MACROPHAGES. Specific CELL MIGRATION ASSAYS have been developed to estimate levels of migration inhibitory factors, immune reactivity against tumor-associated antigens, and immunosuppressive effects of infectious microorganisms.

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).

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.
