Previously however, the nuclear translocation of STAT1 was reported to be inhibited by type II (NTE) Toxoplasma infection [8]; the tyrosine phosphorylation of STAT1 was reported to be inhibited by type I (BK) infection [12], and type I (RH), type II (Pru), and type III (CL14) Toxoplasma strains were suggested to cause dephosphorylation of STAT1 in the nucleus [13]. This evidence concerns the gene STAT1 and infection.
