Toll-like receptor 9 polymorphisms and Hepatitis B virus clearance in Moroccan chronic carriers.

Objectives: Toll-like receptor 9 (TLR9) plays a crucial role in the innate immune response against viral infections. The failure of this system may result, in an attenuated immune response against HBV. Recent research has focused on the possibility of targeting the defects in TLR9 pathway as a novel approach for anti-HBV treatment.
