Dynamic detection of T cell subsets and CD3＋HLA-DR＋T cells in peripheral blood with hand allograft recipients / 临床检验杂志

ABSTRACT

Objective To study dynamic changes of T cell subsets and CD3＋HLA-DR＋T cells in peripheral blood of composite tissue transplantation-hand allograft recipients. Methods The levels of CD3＋、CD3＋CD4＋、CD3＋CD8＋、CD3＋HLA-DR＋T cells and ratio of CD4/CD8 in peripheral blood of hand allograft recipients in different periods were examined by using flow cytometry.The recipients before transplantation were as the control groups.Results The first day after transplantation,the levels of CD3＋、CD3＋CD4＋、CD3＋CD8＋、CD3＋HLA-DR＋T cells and ratio of CD4/CD8 all began to descend.The 3th to 5th day after transplantation,the levels were the lowest.The 8th day,the levels of CD3＋、CD3＋CD4＋、CD3＋CD8＋、CD3＋HLA-DR＋T cells and ratio of CD4/CD8 were eventually rised and go to stable 15th day after transplantation.But the levels of CD3＋、CD3＋CD4＋and value of CD4/CD8 were still lower than those of the contols,and the levels of CD3＋CD8＋、CD3＋HLA-DR＋T cells were higher distinctly.Conclusion Dynamic changes of T cell subsets and active T cells in peripheral blood of composite tissue transplantation-hand allograft recipients were accordant with that of renal allograft recipients with stable period and with stable clinical state of the hand transplantation recipients.
