TLR3 and infection: To investigate the role of TLR3+ DCs in resistance to CVB3 infection, we differentiated DCs in culture from bone marrow cells of WT mice and adoptively transferred them to TLR3 KO mice 1 day after infection with either 107 CVB3 (a viral load that kills all TLR3 KO mice) or 106 CVB3 (a viral load that kills approximately 60% of TLR3 KO mice).
