Previous studies have shown that short-term (4 weeks) or chronic (32 weeks) exposure to trichloroethylene (TCE) in drinking water of female MRL+/+ mice generated CD4(+) T cells that secreted increased levels of interferon (IFN)-γ and expressed an activated (CD44(hi)CD62L(lo)) phenotype.

Also observed was an increase in the expression of Dnmt1 (DNA methyltransferase-1) and decreased expression of several genes known to be downregulated by DNA methylation, namely Ifng, Il2, and Cdkn1a.

CD4(+) T cells from a second study in which MRL+/+ mice were treated for 17 weeks with TCE showed a similar increase in Iap and decrease in Cdkn1a.

|
Hypermethylation of the IFNG promoter in CD4(+) T cells and plasma IFNG was negatively correlated.

|
CD4(+) T cells from healthy individuals co-cultured with SPC-A1 cells generated lower levels of IFNG after activation, elevated expression of DNA methyltransferases (DNMTs), and exhibited hypermethylation of the IFNG promoter.

|
In conclusion, decreased IFNG expression of CD4(+) T cells co-cultured with lung cancer cell is associated with IFNG promoter hypermethylation.

|
Our study suggests that interaction between lung cancer cells and CD4(+) T cells induces DNMT expression and IFNG promoter hypermethylation in CD4(+) T cell, which may serve as an important mechanism of tumor-induced immunosuppression.
