Toll-like receptor (TLR)/MyD88 signalling has emerged as a major pathway of pathogen recognition in the innate immune system. Here, we review recent data that begin to show how this pathway controls the immune response to protozoan infection, with particular emphasis on the opportunistic pathogen Toxoplasma gondii. The various ways that the parasite activates and suppresses TLR/MyD88 signalling defines several key principals that illuminate the complexities of the host-pathogen interaction. We also speculate how TLR/MyD88 signalling might be exploited to provide protection against Toxoplasma, as well as other protozoa and infection in general.

Do you think this receptor is "ground zero"? I have experimented in vivo with calcium blockers, to observe any affects on infective "bradyzoites"[?] There seems to be no reaction.
I am interested on the affects of benzodiazapines in relation to host GABA receptors, and parasite mediators. I think there are global interactions going on, including aMSH and downstream melanocortin involvement.
