Toll-like receptor 3

TLR3 (toll-like receptor 3)

Ampligen is a TLR3 agonist. It stimulates the production of toll-like receptor 3 (TLR3), which is a naturally occurring protein. TLR3 recognizes the dsRNA present in some viruses, such as retroviruses, and stimulates a series of biochemical reactions that result is an increase in the production of interferon. Interferon, an important player in the body's immune system, protects against viral infections and activates immune cells, such as natural killer cells (NK cells).
