It is important to mention that oxPTM for cellular mechanisms of protein uptake in APCs matters, as HOCl‐modified proteins get recognized via mannose receptor (CD206), scavenger receptors A (CD204), and CD36.[79] In contrast, peroxynitrite‐modified proteins may be recognized by toll‐like‐receptor‐4 (TLR‐4), leading to the activation of pro‐inflammatory transcription factor NF‐κB.[80, 81] In our study, we did not observe significant effects on tumor‐infiltrated IAIE+ cells or activity, so we did not investigate protein uptake by APCs. This evidence concerns the gene MSR1 and neoplasm.
