InVivoMAb anti-rat TCR α/β
Product Details
The R73 monoclonal antibody reacts with a framework component of rat α/β TCR (alpha beta T cell receptor). The α/β TCR is expressed by most peripheral T cells, intestinal epithelial lymphocytes, and thymocytes. The R73 antibody has been reported to suppress the development of experimental autoimmune encephalitis and adjuvant arthritis. Moreover, R73 treatment was applied in the field of transplantation and prevented allograft rejection in heart, skin, small bowel, kidney, and cornea.Specifications

The cytokine IL-17 is a key player in autoimmune processes, while the cytokine IL-6 is responsible for the chronification of inflammation. However, their roles in type 1 diabetes development are still unknown.

The anti-rat alpha/beta-TCR, MAb-R73 has been investigated as to its disease modifying activity on adjuvant arthritis (AA), on experimental allergic encephalomyelitis (EAE) and on a local graft versus host (GvH) reaction (popliteal lymph nodes = PLN) in Lewis or Brown-Norway rats. R73 was able to prevent the onset of the AA and even if therapy started after the establishment of AA the MAb was still able to reduce the degree of chronic inflammation and arrest its progress. Intravenous MAb-R73 application also reduced the signs of EAE and prevented mortality. This was even seen when the substance was given after the outbreak of the clinical symptoms or when the F(ab)2 fragment of this MAb was used. Also in the model of local GvH reaction R73 acted therapeutically and lowered the PLN weights.
