TLR2

TLR2 (Toll-like receptor 2) is a protein found on certain immune cells that helps the body detect common components of bacteria, fungi, and some viruses. When TLR2 recognizes these microbial signatures, it triggers the immune system to respond, activating inflammation and other defense mechanisms to fight infection. Think of TLR2 as part of the body’s early warning system, identifying potential threats and alerting the immune system to act quickly. This process is essential for maintaining health, preventing infections, and shaping appropriate immune responses.
