Research on herpes simplex virus (HSV) has highlighted various aspects of its pathology and potential therapeutic interventions. One significant study investigated the role of berberine in herpes simplex keratitis (HSK), revealing that berberine interacts with eukaryotic translation initiation factor 2-alpha kinase 2 (EIF2AK2) to mitigate the effects of HSV-1 on corneal cells (ref: Lin doi.org/10.1016/j.phymed.2025.157112/). Another important finding was the association of specific viral antibodies with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis following herpes simplex encephalitis, indicating a potential biomarker for predicting neurological outcomes in affected patients (ref: Kreye doi.org/10.1016/j.bbi.2025.106073/). Additionally, the development of oncolytic HSV engineered to express interleukin-12 and interleukin-15 demonstrated promising antitumor effects, suggesting a dual role for HSV in both viral pathogenesis and cancer therapy (ref: Zhang doi.org/10.1016/j.omton.2025.201025/). These studies collectively underscore the complexity of HSV interactions with host immune responses and the potential for therapeutic exploitation of these interactions.
