Multi-parameter prediction of HLA class Ⅰ restricted cytotoxic T lymphocyte epitopes for human proliferating cell nuclear antigen

Objective To predict the HLA class Ⅰ restricted cytotoxic T lymphocyte epitopes for human proliferating cell nuclear antigen (PCNA). Methods By using 3 epitope prediction databases which including MHC binder ( BIMAS and SYFPEITHI databases) and proteasome cutting site ( PAProC databases), the epitopes of PCNA were predicted by analyzing several parameters and methods. Results After comprehensive analysis,we have obtained two possible HLA-A0201 restricted CTL epitopes SMSAD-VPLV (228-236, score 447 633. 595 ) and LINEACWDI ( 22-28, score 127 966.779);two HLA-A24 re-stricted CTL epitopos DYEMKLMDL ( 113-121, score 563 994.9 ) and EFARICRDL ( 143-151, score 40 540.7);two HLA-A1101 restricted CTL epitopes LTSMSKILK (72-80, score 1334. 2680 ) and DVPLV-VEYK (232-240,score 736.9236). Conclusion The multi-parameter epitope prediction method is feasi-ble for cytotoxic T lymphocyte epitope prediction.

肿瘤Ki-67抗原HLA-A2限制性细胞毒性T淋巴细胞表位的鉴定

Objective To identify the HLA-A2-restricted CTL epitopes encoded by antigen segment of Ki-67 for preparation of tumor vaccines. Methods Two epitope prediction databases ( BIMAS and SYFPEITHI) were used to predict the epitopes of Ki-67, and 7 peptides were synthesized as the candi-dates. The prediction was evaluated by peptide-binding test. ELISPOT was used to inspect the IFN-γ secre-ted by CTLs in order to reflect the immunogenicity of the peptides. Results The purities of synthetic pep-tides and positive control peptide were all above 95%. Peptide-binding test displayed that LQGETQLLV (280-288) of Ki-67 could bind with HLA-A2 molecule more strongly. ELISPOT assay displayed that LQGETQLLV could induce activation of specific CTLs. Conclusion LQGETQLLV (280-288) might be the HLA-A2-restricted CTL epitope of Ki-67 antigen.

联合腰-硬镇痛对分娩产妇IL-1β、IL-10及T细胞亚群的影响

Objective To investigate the effect of combined spinal-epidural analgesia(CSEA) on immunological function and Th1/Th2 balance by observing the levels of serum T-lymphocyte subsets,IL-1β and IL-10 during labor in maternity.Methods Fifty healthy primipara expecting spontaneous labor were randomly divided into two groups(n=25).CSEA was performed with 20 μg fentanyl for lumbar analgesia and with complex of ropivacaine(0.1%) and fentanyl(2 μg/ml) for epidural analgesia in group Ⅰ,and no labor analgesia was given in group Ⅱ.Serum cortisol,IL-1β,IL-10 and T lymphocyte subsets was detected at cervical dilation of 2 cm-3 cm (T1),fetal disengagement (T2) and 24 h after childbirth (T3).Labor progress,VAS and neonatal Apgar score were recorded.Results The active phase of the first labor stage significantly shortened in group Ⅰ compared to that in group Ⅱ (P＜0.05),without difference in neonatal Apgar score between two groups.Along with labor progress,the level of serum IL-1β markedly increased in two groups,and the levels of cortisol,IL-1β and IL-10 were obviously decreased at T2 in group Ⅰ compared to those in group Ⅱ(P＜0.05).The levels of serum CD3+,CD4+,and CD4+/CD8+ decreased in both groups,with significant reduction at T3 (P＜0.05) and more significant in group Ⅱ than in group Ⅰ (P＜0.05).Conclusion CSEA shortens the active delivery phase in the first stage of labor and alleviates pain stress-induced inhibition on immune function and may benefit the balance of Th1/Th2 in maternity.
