Nitric oxide is a vital part of innate immune defense against pathogens.
The body’s innate immune system acts like a first responder, rushing to the point of infection to begin battling the invaders. Nitric oxide is a key component of the innate immune response, it works to prevent viral access to the body and disrupt replication and release, while sending an alert to the body’s neutrophils, macrophages, and Natural Killer (NK) cells to help contain, attack, and kill the virus.
In order to infect us, airborne viral pathogens, like coronavirus, must:
the body through the epithelial cells in our upper respiratory tract (nose, mouth and back of throat).
by hijacking the cell’s reproductive mechanisms to create new virus particles, called virons.
the replicated virons throughout the body to infiltrate more cells and continue the cycle of infection.
