PRDX1 and cancer: Other proteins found in our study have been suggested as DAMPs, including peroxiredoxin 1 (PRDX1), which binds to TLR‐4 after secretion from cancer cells (Liu et al., 2016; Riddell et al., 2010), or prolyl endopeptidase (PREP) that cleaves collagen to produce proline‐glycine‐proline (PGP), which acts as a DAMP (Patel & Snelgrove, 2018) and participates in the recruitment of neutrophils (Weathington et al., 2006).
