The article discusses the potential of pyroglutamyl aminopeptidase 1 (PGP-1) as a novel target for diagnosing and treating inflammation. PGP-1 is a cysteine peptidase found in various organisms and tissues, with roles in peptide absorption, catabolism, and disease regulation. Studies have shown an increase in PGP-1 levels in inflammatory conditions, suggesting its involvement in inflammation-related diseases like cancer. Further research is needed to understand PGP-1's mechanism in inflammation and develop effective inhibitors for therapeutic purposes. The authors highlight the importance of exploring PGP-1 as a diagnostic and therapeutic tool for inflammation and related diseases. [Extracted from the article]
