Herpes simplex virus: receptors and ligands for cell entry

Area of Science:

• Virology
• Cell Biology
• Immunology

Background:

• Herpes simplex virus (HSV) entry into host cells is a complex process.
• It requires interactions between viral glycoproteins and specific cell surface receptors.

Purpose of the Study:

• To review the cell surface receptors and viral ligands involved in HSV entry.
• To discuss the roles of viral glycoproteins (gC and gD) in viral entry, immune evasion, and cellular responses.

Main Methods:

• Literature review of studies on HSV-host cell interactions.
• Analysis of the molecular mechanisms of viral entry and immune evasion.

Main Results:

• HSV utilizes multiple cell surface receptors, including heparan sulfate, TNF receptor family, and immunoglobulin superfamily members.
• Viral glycoproteins gB, gC, and gD are key ligands mediating these interactions.
• HSV gC can bind complement C3b, inhibiting complement-mediated neutralization.

Conclusions:

• Understanding HSV entry mechanisms is vital for developing antiviral strategies.
• Viral glycoproteins play multifaceted roles beyond cell entry, influencing host immune responses.
