What is the Origin of Toll-Like Receptor 4?

The receptor is named after the Toll gene, first discovered in fruit flies, which plays a role in their embryonic development and immunity. The human homolog, TLR4, was later identified as a key component of the mammalian innate immune response. Its discovery was crucial for understanding the immediate, non-specific defense mechanisms of the body.

What is the Mechanism of Toll-Like Receptor 4?

TLR4 operates by forming a complex with accessory proteins (MD-2 and CD14) upon binding to its ligand, such as LPS. This binding triggers a conformational change that recruits adapter proteins inside the cell, primarily through the MyD88 pathway. This intracellular cascade culminates in the activation of the transcription factor NF-$kappa$B, which then translocates to the nucleus and initiates the transcription of pro-inflammatory genes, leading to the rapid production of cytokines and chemokines that drive the inflammatory response.

Toll-Like Receptor 4

Meaning

Toll-Like Receptor 4 (TLR4) is a pattern recognition receptor expressed on the surface of various immune cells, playing a central role in the innate immune system’s initial response to pathogens and cellular damage. It functions as a sensor for specific molecular patterns, notably lipopolysaccharide (LPS) from Gram-negative bacteria, and various endogenous danger signals. Activation of TLR4 initiates a powerful pro-inflammatory signaling cascade, linking microbial exposure to systemic inflammation.
