Ocular and neuronal cell apoptosis during HSV-1 infection: a review

Area of Science:

• Virology
• Cell Biology
• Molecular Biology

Background:

• The herpes simplex virus type 1 (HSV-1) is a common human pathogen.
• Apoptosis, or programmed cell death, is a critical cellular process.
• HSV-1's interaction with apoptosis is complex and context-dependent.

Purpose of the Study:

• To review the dual role of HSV-1 in regulating apoptosis.
• To elucidate the mechanisms HSV-1 utilizes to inhibit or promote apoptosis.
• To highlight the differential strategies employed by HSV-1 across various cell types and tissues.

Main Methods:

• Literature review of existing studies on HSV-1 and apoptosis.
• Analysis of molecular mechanisms involved in HSV-1-mediated apoptosis.
• Comparative examination of HSV-1's effects in different cellular contexts.

Main Results:

• HSV-1 can both induce and suppress apoptosis depending on the cell type and infection stage.
• Viral proteins play key roles in modulating apoptotic signaling pathways.
• HSV-1 employs diverse strategies, including blocking caspase activation and altering mitochondrial function, to evade apoptosis.

Conclusions:

• HSV-1 exhibits a complex regulatory relationship with the apoptotic pathway.
• Understanding these mechanisms is crucial for developing antiviral therapies.
• Further research is needed to fully unravel the intricacies of HSV-1's apoptotic manipulation.
