| 1 | Induction of HLA-G expression in a melanoma cell line OCM-1A following the treatment with 5-aza-2'-deoxycytidine显示文摘The non-classical HLA class I antigen HLA-G is an immune modulator which inhibits the functions of T cells, NK cells, and the Dendritic cells (DC). As a result, HLA-G expression in malignant cells may provide them with a mechanism to escape the immune surveillance. In melanoma, HLA-G antigen expression has been found in 30% of surgically removed lesions but in less than 1% of established cell lines. One possible mechanism underlying the differential HLA-G expression in vivo and in vitro is that the HLA-G gene is epigenetically repressed in melanoma cells in vitro. To test this hypothesis, we treated the HLA-G negative melanoma cell line OCM-1A with the DNA methyltransferase inhibitor 5-aza-2’-deoXycytidine (5-AC) and analyzed whether HLA-G expression can be restored. Our data strongly suggest that HLA-G is silenced as a result of CpG hypermethylation within a 5’ regulatory region encompassing 220 bp upstream of the start codon. After treatment, HLA-G mRNA expression was dramatically increased. Western blot and flow cytometry showed that HLA-G protein was induced. Interestingly, HLA-G cell surface expression on the 5-AC treated OCM-1 A cells is much less than that on the HLA-G positive JEG-3 cells while a similar amount of total HLA-G was observed. Possible mechanisms for the difference were analyzed in the study such as cell cold-treatment, peptide loading and antigen processing machinery components (APM) as well as β2 microglobulin (β2-m) expression. Data revealed that the APM component calreticulin might be involved in the lower HLA-G surface expression on OCM-1 A cells. Taken together, our results indicated that DNA methylation is an important epigenetic mechanism by which HLA-G antigen expression is modulated in melanoma cells in vitro. Furthermore, to the first time, we hypothesized that the deficiency of calreticulin might be involved in the low HLA-G surface expression on the 5-AC treated OCM-1 A cells. | Wei Hua YAN Ai Fen LIN Chien Chung CHANG Soldano FERRONE | 2005 | Cell Research2005,15,7: | 5 |
| 2 | 靶向攻击肿瘤的免疫疗法显示文摘用单克隆抗体治疗癌症一直是肿瘤免疫学研究的热点之一。以往的抗体治疗均以癌细胞表面蛋白为靶标,因为全抗体分子太大而不能穿过细胞膜。最近新加坡科技研究局下属的分子与细胞生物学研究所(IMCB)曾琦博士及其团队的研究发现,抗体治疗不仅能以胞外癌蛋白为靶标,也能以胞内癌蛋白为靶标,进入胞内杀死癌细胞,从而抑制癌细胞的生长;这些发现对癌症的免疫治疗具有突破性的意义。现将其主要内容摘录如下,供我国学者参考。读者有意阅读原文请看:[Ferrone S.Hidden immunotherapy targets challenge dogma,Sci Transl Med,2011,3(99):99ps38] | Soldano Ferrone 江丽君 | 2012 | 微生物学免疫学进展2012,40,1: | 1 |

| 10 | 癌症的单克隆抗体免疫治疗显示文摘单克隆抗体是许多恶性疾病的有效治疗手段。然而,与抗体的其他作用机制相比,抗体诱发肿瘤抗原特异性免疫应答的能力很少受到关注。本文收集相关证据,对研制可诱发宿主产生肿瘤抗原特异性免疫应答的抗体的合理性进行探讨。通过诱导抗体依赖性细胞毒性效应、刺激抗体靶向的肿瘤抗原交叉提呈或触发独特型网络,均可诱导该类应答。而改进治疗方式或实施联合治疗,将有可能延长、放大或调节这类免疫应答,并提高癌症抗体治疗的临床效果。 | Louis M Weiner Madhav V Dhodapkar Soldano Ferrone 王顺涛(译) | 2009 | 世界临床医学2009,,11: | 0 |
