Its molecular structure contains a typical reactive center loop that can participate in the regulation of the release of various inflammatory factors.[8] A study investigating the use of SERPING1 expression levels to differentiate between active TB and latent TB infection found that SERPING1 as a biomarker for TB is heterogeneous across different regions and is associated with active TB.[9] However, the role of SERPING1 in drug resistance of Mycobacterium TB remains underexplored. Here, SERPING1 is linked to tuberculosis.
