Mucosal Immunity

What is Mucosal Immunity?

Your mucosal surfaces are lined with a specialized immune layer composed of Secretory IgA (sIgA) antibodies, which coat the mucosal lining. These antibodies block HSV from attaching to cells, the first step in infection, and help neutralize HSV before it reaches nerve endings.

The mucus itself contains antiviral factors and acts as a physical barrier, trapping viral particles and preventing their spread. These include dendritic cells, macrophages, and T cells. These cells detect HSV immediately, eliminate infected cells, and recruit additional immune support.

Tissue-Resident Memory T-cells (TRM) are long-term immune cells that permanently reside in the mucosa near the site of past outbreaks. They stay “parked” in the tissue like guards on standby. Their job is to stop HSV reactivation early, often before symptoms appear. This is one of the strongest forms of protection against HSV recurrence.

Why Mucosal Immunity Matters When You Live With Herpes

HSV hides in nerve ganglia, but outbreaks occur on mucosal surfaces. Your mucosal immune system determines how often HSV reactivates, how severe outbreaks are, whether the virus is stopped early (silent shedding), and how well your body handles HSV triggers, which is why mucosal immunity matters when you live with herpes.
