TLR7 modulating B-cell immune responses in the spleen of C57BL/6 mice infected with Schistosoma japonicum.

B cells played an important role in Schistosoma infection-induced diseases. TLR7 is an intracellular member of the innate immune receptor. The role of TLR7 on B cells mediated immune response is still unclear. Here, C57BL/6 mice were percutaneously infected by S. japonicum for 5-6 weeks. The percent...
