摘要

Toll-like receptor 3 (TLR3) binds and signals in response to dsRNA and poly(I:C), a synthetic double stranded RNA analog. Activation of TLR3 triggers innate responses that may play a protective or detrimental role in viral infections or in immune-mediated inflammatory diseases through amplification of inflammation. Two monoclonal antibodies, CNTO4685 (rat anti-mouse TLR3) and CNTO5429 (CDRs from CNTO4685 grafted onto a mouse IgG1 scaffold) were generated and characterized. These mAbs bind the extracellular domain of mouse TLR3, inhibit poly(I:C)-induced activation of HEK293T cells transfected with mTLR3, and reduce poly(I:C)-induced production of CCL2 and CXCL10 by primary mouse embryonic fibroblasts. CNTO5429 decreased serum IL-6 and TNFalpha levels post-intraperitoneal poly(I:C) administration, demonstrating in vivo activity. In summary, specific anti-mTLR3 mAbs have been generated to assess TLR3 antagonism in mouse models of inflammation.
