Herpes simplex viruses (HSV-1 and HSV-2) cause global morbidity and synergistically correlate with HIV infection. HSV exists life-long in a latent form in sensory neurons with intermittent reactivation, in despite of host immune surveillatlce. While abundant evidence for HSV interfering with innate immune responses so as to favor the replication and propagation of the virus, several lines of evidence declare that HSV attenuates adaptive immunity by various mechanisms, including but not limited to the ablation of antigen presentation, induction of apoptosis, and interruption of cellular signaling. In this review, we will focus on the perturbative role of HSV in T cells signaling.
