Mazur et al. [61] analysed the Nrf2 –sulfiredoxin-1 (SRX1) pathway by several methods to assess the cell-specific localization and expression of NRF2 and SRX1, and selected proteins linked to their activation or stability in human IPF and non-specific interstitial pneumonia (NSIP) patients. Here, SRXN1 is linked to idiopathic pulmonary fibrosis.
