Figure 1 Representative example demonstrating CCR5 expression as observed on flow cytometry histograms and functional blockade of CCR5 with addition of maraviroc. (A1) Shows CCR5 expression in a healthy control patient. (A2) Shows the internalization of CCR5 expression with the addition of CCL5. (A3) Shows the preservation of CCR5 expression with addition of maraviroc, despite addition of CCL5. (B1) Shows the pretransplantation CCR5 expression of a patient on study. (B2) Shows the internalization of CCR5 expression with the addition of CCL5. (C1) Shows the expression of CCR5 on day 0 and day +14 after stem cell transplantation. Patient is currently on maraviroc. (C2) Shows the preservation of CCR5 expression despite addition of CCL5.
