PADI4 and systemic lupus erythematosus: As for autophagy, we found an interindividual variability for PAD4 enzyme and citrullinated vimentin levels (Figure 4B,C,E,F), expressing lower levels of markers in comparison with SLE patients’ PBMCs at baseline (t0) and after 2 and 4 weeks of BLM therapy, but similar to the SLE patients’ PBMCs after 12 weeks of treatment.
