背景信息

**Background of PGLYRP2 Recombinant Protein**

Peptidoglycan recognition protein 2 (PGLYRP2) is a member of the PGLYRP family, a group of pattern recognition receptors (PRRs) that specifically bind to peptidoglycan (PGN), a key component of bacterial cell walls. Unlike other PGLYRPs (PGLYRP1. 3. 4), which exhibit direct bactericidal activity, PGLYRP2 functions as an N-acetylmuramoyl-L-alanine amidase, enzymatically cleaving PGN to modulate immune responses. This intracellular protein is constitutively expressed in the liver and secreted into the bloodstream, playing a regulatory role in innate immunity by preventing excessive inflammation triggered by bacterial PGN.

Recombinant PGLYRP2 is produced using biotechnological systems (e.g., *E. coli* or mammalian cell expression) to generate purified, functional protein for research and therapeutic applications. Its enzymatic activity helps degrade pro-inflammatory PGN fragments, making it a critical subject in studies of immune homeostasis, inflammatory diseases, and host-microbe interactions. Dysregulation of PGLYRP2 has been linked to chronic inflammatory conditions, such as inflammatory bowel disease (IBD) and rheumatoid arthritis, highlighting its potential as a therapeutic target.

Research on recombinant PGLYRP2 also explores its diagnostic utility, as altered levels correlate with bacterial infections or dysbiosis. Additionally, it serves as a tool to investigate PGN metabolism and its impact on gut microbiota composition. Recent studies suggest its involvement in modulating autophagy and apoptosis, further expanding its biological significance beyond innate immunity. Overall, PGLYRP2 recombinant protein is pivotal in advancing understanding of immune regulation and developing strategies to manage inflammation-related disorders.
