We then investigated the CD4 T cell response in seven patients treated with Ifx (n = 6) or Rtx (n = 1) (one with granulomatous uveitis; five with Crohn’s disease, and one with rheumatoid arthritis) having developed ADAs against Ifx or Rtx (Table S5 in Supplementary Material). This evidence concerns the gene CD4 and Crohn disease.
