Levels of human immunodeficiency virus type 1-specific cytotoxic T-lymphocyte effector and memory responses decline after suppression of viremia with highly active antiretroviral therapy.

abstract：:Two mutant strains (vi12 and vi13) of herpes simplex virus that contain insertion mutations in the sequences that encode the DNA-binding domain of viral regulatory protein ICP4 were generated. Both mutations disrupted specific DNA binding and resulted in transcriptionally inactive molecules; however, the ability of th...
