**摘要**：利用重组TIRAP蛋白进行体外pull-down实验，证明TIRAP直接结合TLR2和TLR4的胞内TIR结构域，并招募MyD88以激活NF-κB通路。研究还发现，TIRAP缺失会显著抑制TLR2/4介导的炎症因子产生，强调了其在天然免疫中的核心作用。

TIRAP (Toll/interleukin-1 receptor (TIR) domain-containing adaptor protein), also known as MAL (MyD88 adaptor-like), is a key signaling protein in innate immune responses. It acts as an adaptor molecule that mediates downstream signaling of Toll-like receptors (TLRs), particularly TLR2 and TLR4. which recognize pathogen-associated molecular patterns (PAMPs) from bacteria, viruses, and fungi. TIRAP contains a C-terminal TIR domain that facilitates interactions with TLRs and recruits MyD88. another adaptor protein, to activate NF-κB and MAPK pathways, triggering pro-inflammatory cytokine production.
Recombinant TIRAP proteins are engineered versions of this adaptor, typically produced in expression systems like *E. coli* or mammalian cells. These proteins retain functional domains critical for studying TLR signaling mechanisms, such as ligand binding or protein-protein interactions. Researchers use recombinant TIRAP to dissect its role in immune activation, screen for inhibitors to modulate excessive inflammation, or explore structural features through techniques like X-ray crystallography.
Interest in TIRAP stems from its dual role in health and disease. While essential for pathogen defense, dysregulated TIRAP signaling is linked to chronic inflammatory disorders (e.g., sepsis, atherosclerosis) and autoimmune diseases. Recombinant TIRAP enables targeted studies to develop therapeutics that fine-tune TLR responses without compromising overall immunity. Additionally, TIRAP-deficient animal models, validated using recombinant protein tools, highlight its non-redundant functions in specific TLR pathways. Overall, recombinant TIRAP serves as a vital resource for unraveling innate immune regulation and advancing precision immunomodulation strategies.
