Our results in KTR with ELTGF under 2-drug immunosuppression are in keeping with those previously reported in KTR patients, who did not require continuous immunosuppressive therapy and have different subsets of suppressive cells, including higher proportions of CD19+/CD24hi/CD38hi/CD5+ IL-10-secreting B cells compared to those patients with CGD [25–28]. This evidence concerns the gene IL10 and chronic granulomatous disease.
