ABSTRACT

Objective To explore the feasibility of mediating recipient lymphocyte reaction with donor dendritic cells (DCs) in renal allograft recipients. Methods Donor bone marrow monocytes (BMMCs) were isolated and cryopreserved in liquid nitrogen before kidney transplantation. At 0 day, 1month,3 month, 6 month and 9 month post-operation, CD34+ cells which were isolated from frozen BMMCs and cultured into DCs as well as the peripheral blood lymphocytes (PBLs) of donors were used as the stimulating cells to the PBLs of recipients and healthy volunteers. The number of viable DCs from frozen- and room temperature-preserved BMMCs was counted and the reactions of recipients'and healthy volunteers' lymphocytes to DCs and donor PBLs were measured. Results 6. 8 × 107BMMCs were isolated from each 10 ml of donor bone marrow on average while (4. 10 ± 0. 58) × 105CD34+ cells were isolated by magnetic active cell sorting (MACS). There was no significant difference in the isolating rate of recovered CD34+ cells at each observation point postoperatively. The percentage of viable BMMCs and CD34+ was decreased significantly at 1 month after surgery, then, decreased slowly and progressively. The decreasing rate of BMMCs was higher than CD34+. The rate of viable DCs was maintained stable (93. 2%-94. 8% ) in each group. The reactions of recipients' and healthy volunteers' lymphocytes to DCs were stronger than those to donor PBLs (P<0. 05). The reactions of healthy volunteers' lymphocytes to DCs were maintained stable while those of recipients' were fluctuating. Conclusion Bone marrow-derived DCs are superior to PBLs in mediating long-term lymphocyte reaction after kidney transplantation due to their stable viability and stimulating ability to lymphocytes. Only once collection of a small quality of bone marrow of donors is needed to meet the demand of immune monitoring at any time after transplantation.

ABSTRACT

ObjectiveTo explore the feasibility of mediating recipient lymphocyte reaction with donor dendritic cells (DCs) in renal allograft recipients to guide individualized inmunosuppressive therapy. Methods From Jan. 2008 to Jan. 2010, 30 recipients received living related kidney transplantation were successively and divided into 2 groups according to the strategies of the correction of the dosage of immunosuppressant, 15 in each group. The strategy of immunosuppressive therapy in both groups was Tac + MMF + Pred. The correction of the dosage of immunosuppressant in experimental group was conducted by recipient lymphocyte reaction with donor DC (LR) combined with Tac and MPA blood concentration monitoring. Only blood concentration monitoring of drugs was applied in control group. Examinations of liver and renal function, blood and urine routine as well as blood sugar were done monthly for 1 year. ResultsDuring the follow-up period, the rate of acute rejection in experimental group and control group was 13. 3 % and 46. 7 % respectively (P<0. 05) ;the rate of infection in experimental group and control group was 6. 7% and 40. 0% (P<0. 05)respectively; the adverse reaction rate in experimental group and control group was 13. 3% and 46. 7%(P<0. 05). There was no significant difference in the serum creatinine level between the two groups at each observation point. ConclusionThe application of combined recipient LR with donor DC and blood concentration monitoring of drugs in individualized irnmunosuppressive therapy is more comprehensive and accurate.

ABSTRACT

ObjectiveTo evaluate the efficacy and safety of domestic taerolimus in the manage-ment of acute rejection in renal transplantation reeipienta.MethodsA multieeneter, open and com-parative study for domestic Taerolimua and Prograf was performed. Eighty reeipienta of first allogenie renal transplantation were randomized into 2 groups: ①Experimental group (accepting Fumeixin ad-ministration, n=58) included 23 males and 35 females with the mean age of(39.1±9.6)years. ②Control group(accepting Prograf administration, n=22) included 12 males and 10 females with the mean age of(41.34±8.5)years. There was no significant difference in the volume, warm and cold is-chemia time of donor renal, age and sex of donor. All of the 80 cases accepted tacrolimus (domestic or foreign made, at the dose of 0. 10~0. 15 mg·kg-1·d-1 , q 12 h) treatment that combined with MMF and prednisone posttransplantation. Tacrolimus CO was aimed to 8-12 ng/ml in the first 60 days and 5-10 ng/ml later. The dose of MMF was according to the rule of each transplantation center based on the following recommendation: 1.5-2.0 g/d for the weight above 70 kg, 1.5 g/d for the weight 50-69 kg, and 1.0 g/d for the weight below 49 kg, in two divided doses. Prednisone was ad- ministrated as per ruler of each center. ResultsObservation termination was 3 months. Morbility of actue rejection was 3.40% (2/58)and 13.6% (3/22) in experimental and control group(P>0.05). Ad-verse events including hypertension, hyperlipemia, hyperglycemia and slight abnormality of liver func-tion occurred in 36. 2%(21/58) and 36. 4% (8/22) cases of experimental and control group(P> 0. 05). The survival rate in the 2 groups was 100%. The dose of tacrolimus in experimental group was significantly lower than that in the control group at 8 and 12 weeks posttransplant, while drug valley concentration in serum was proximal in 2 groups during the whole observation period.Conclusion Domestic tacrolimus capsules can be used effectively and safely in the management of acute rejection in renal transplantation.

ABSTRACT

BACKGROUND: Previous studies showed that donor systemic injection of B7/CD28 costimulatory blocker cytotoxic T lymphocyte associated antigen 4 immunoglobulin (CTLA-4Ig) needed in T cell activation can markedly prolong the survival time of rat renal allografts, which, however, has limitations, such as high dose, extensive influence, poor specificity, systemic adverse reactions.OBJECTIVE: In order to improve the targeting of CTLA-4Ig, we modified the dendritic cells of donors and recipients in vitro with CTLA- 4Ig and observed the influence of two kinds of dendritic cells applied alone or together on the survival of renal allografis in rats.DESIGN, TIME AND SETTING: The randomized controlled animal experiment was performed between April 2003 and July 2004 at Laboratory of Department of Urinary Surgery, Xinqiao Hospital, the Third Military Medical University, Chongqing, China.MATERIALS: Kidney donor: inbred Brown-Norway rats, kidney recipient: inbred Lewis rats, unrelated lymphocyte donor: Wistar rats.METHODS: Bone marrow derived dendritic cells of Lewis and Brown Norway rats were modified with CTLA- 4Ig gene recombinant adenovirus in vitro. Animal models of kidney transplantation were built with Brown Norway rats as donors while Lewis rats as recipients. The modified dendritic cells were injected into Lewis rats through femoral vein 24 hours before kidney transplantation alone (group 1 (n=8), donor dendritic cells; group 2 (n=8), recipient dendritic cells) and in combination (group 3 (n=8), donor and recipient dendritic cells). While the recipients without injection were used as control (group 4 (n=6)).MAIN OUTCOME MEASURES: Survival time of renal allografts; the reaction degrees of splenocytes to donor and unrelated antigen determined by MTT method on day 20 postoperation.RESULTS: Survival time of renal allografts in group 2 was not prolonged compared with group 4 while the survival time was markedly prolonged in group 3 (P < 0.01). The response of rat splenocytes to donor antigen in group 1 and group 3 was obviously lower than that in group 4 (P < 0.01), while the response to unrelated antigen was similar to group 4.CONCLUSION: Donor dendritic cells modified with CTLA- 4Ig can significantly prolonged survival time of rat renal allografts and the administration of both donor and recipient dendritic cells modified with CTLA- 4Ig can induce a longer survival time of renal allografts. Recipient dendritic cells cannot prolong the survival time of renal allografts.

ABSTRACT

Objective To investigate the immunosuppression function of a novel HLA derived peptide, RDP1258, and its mechanisms. Methods A peptide derived from HLA, RDP1258, was chemically synthesized by artificial solid phase synthesis. Effects of the peptide on alloreactive cytotoxic activity of rat spleen cells and heme oxygenase 1 (HO 1) activity were observed using 3H TdR method and enzyme chemistry method, respectively. Results The synthetic HLA derived peptide could obviously inhibit the proliferation of rat spleen cells and mixed lymphocyte reaction, and reduce HO activity in a dose dependent manner in vitro . Conclusion RDP1258 can significantly inhibit the proliferation of rat spleen cells induced by mitogen and isoantigen possibly by means of affecting HO 1 activity.
