| the ifn-gamma +874t/a gene polymorphism is associated with retinochoroiditis toxoplasmosis susceptibility. | toxoplasmosis is a worldwide zoonosis that generally produces an asymptomatic infection. in some cases, however, toxoplasmosis infection can lead to ocular damage. the immune system has a crucial role in both the course of the infection and in the evolution of toxoplasmosis disease. in particular, ifn-gamma plays an important role in resistance to toxoplasmosis. polymorphisms in genes encoding cytokines have been shown to have an association with susceptibility to parasitic diseases. the aim of ... | 2009 | 19547871 |
