Combination of CTLA-4 and TGFbeta1 gene polymorphisms associated with dengue hemorrhagic fever and virus load in a dengue-2 outbreak

The pathogenesis of dengue hemorrhagic fever (DHF) has been considered to be massive immune activation of T cells. Abnormal expression of the immune regulatory molecules, CTLA-4 and TGFbeta1, leads to disturbances of regulatory T cell immune response. We investigate the contribution of CTLA-4 and TG...

520 |a The pathogenesis of dengue hemorrhagic fever (DHF) has been considered to be massive immune activation of T cells. Abnormal expression of the immune regulatory molecules, CTLA-4 and TGFbeta1, leads to disturbances of regulatory T cell immune response. We investigate the contribution of CTLA-4 and TGFbeta1 in DHF by analyzing them for association with virus load in blood and polymorphisms of CTLA-4 +49A/G, and TGFbeta1 -509C/T in a DEN-2 outbreak. The increased frequency of the TGFbeta1 -509 CC genotype in patients with DHF was compared to those with dengue fever (OR=1.9, p=0.034). Moreover, the presence of the CTLA-4 +49 G allele and TGFbeta1 -509 CC genotype increased the susceptibility to risk of DHF (OR=2.1, p=0.028) and significantly higher virus load (p=0.013). This finding suggests that a combination of CTLA-4 and TGFbeta1 polymorphisms is associated with the susceptibility of DHF and higher virus load
