Toll-like Receptor (TLR)

Toll-like receptors (TLRs) are specialized proteins found on immune cells that act as early sensors for potential threats, such as bacteria, viruses, and fungi. When these receptors detect specific molecules characteristic of pathogens, they trigger an immune response, helping the body identify and combat infections. TLRs are essential for initiating the body's defense system and also influence the way immune cells communicate and activate. They play a crucial role in maintaining health by recognizing harmful invaders quickly and efficiently.
