Activation of resting T lymphocytes by a monoclonal antibody directed against an allotypic determinant on the T cell receptor.

abstract：:C57BL/10ScCr (Cr) mice carry a deletion of the Toll-like receptor 4 (tlr4) gene (i.e. they are tlr4(0/0)) and are thus refractory to LPS effects. Insertion of wild-type tlr4 transgene into the tlr4(0/0) Cr germ line endowed LPS susceptibility in the two transgenic lines created, indicating that TLR4 is the only limiti...
