Discovery Could Lead To Novel Approaches In HIV Treatment

...ith HIV and found that,already in the first months following the onset of infection, thymicfunction is decreased. Such a decrease results in a loweredT-lymphocyte production by the thymus.These findings pave the way to the development of novel immunotherapiesof HIV-infected individuals. Such immunotherapies co...
