Different strains of T.Gondii modify host gene expression differently - but all upregulate VIPR2 a recently characterised important schizophrenia gene. VIPR2 expression in macrophages is controlled by Toll receptor TLR2 or TLR2/6 (Herrera et al, 2009). T.Gondii binds to galectin 3, an associate of TLR2 , in macrophages Debierre-Grockiego et al 2010
The KEGG pathways traced out by schizophrenia genes - now including VIPR2, include several viral and bacterial entry pathways, with toxoplasmosis heading the list.
