SAMHD1: Impact on inflammation and DNA damage response in HIV-1 and malignant diseases


SAMHD1, a negative regulator of the innate response, is a mediator of immune evasion for HIV-1 and has been linked DNA damage response and malignant tumor development if mutated or downregulated. A key to understand the role of SAMHD1 in immune escape mechanisms of chronic viral infections and cancer will be to characterize (i) identified proteins that may control the activity of SAMHD1 and (ii) the microenvironment induced by inactive SAMHD1. These results will support the development of compounds to improve vaccine design aiming to induce specific immune responses and to support novel strategies to fight cancer.
