Live mf of B malayi down-regulate TLR4 protein expression. mhDCs were exposed to live mf for 72 hours. TLR3 (A) and TLR4 (B) expression using immunoblot analysis in 1 representative of 4 (for TLR3) and 1 representative of 6 (for TLR4) different donors. Graphs to the side of each blot demonstrate the ratio of TLR to tubulin for each of the 4 or 6 donors. *P = .03.
