CD5 and chronic granulomatous disease: 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].
