cytotoxic lymphocyte 中文意思是什麼
-
T cell will be apopotosis, clone depletion and / or anergy, in turn inducing an antigen - specific tolerance. ctla4 ( cytotoxic t lymphocyte associated antigen 4 ), a prominent negative costimulator, can competitively bind with b7, and block b7 - cd28 pathway and t cell activation by producing inhibitory singals
Ctla4 （ cytotoxictlymphocyteassociatedantigen4 ）作為一種主要的共刺激負調節劑，可競爭性結合b7分子，阻斷b7 - cd28途徑、並通過產生抑制性信號使t細胞活化障礙。 -
Hi our study, dendritic cells ( dcs ) were derived from the cultivation of peripheral blood monocytes in vitro successfully. then to observe whether dcs transfected with carcinoembryonic antigen ( cea ) - vaccinia recombinant virus ( rv - cea ) can induces cytotoxic t lymphocyte - mediated cea - specific immunity in vitro
體外成功地完成了cd14 +單核細胞來源的樹突狀細胞（ dc ）的培養，並進一步研究人癌胚抗原重組痘苗病毒（ rv - cea ）轉染dc后體外誘導的cea特異性細胞免疫。 -
Cea gene was transferred into human dcs, and specific anti - cancer effecs induced by the vaccine was observed. this test is part of my tutor ' s. hang you - tian has observed the induction of crcinembryonic antigen ( cea ) - specific cytotoxic t - lymphocyte responses in vitro when he transfected dcs with pcdna3 - cea, and has observed the immunity effects of the dcs ( pcea ) inoculateing against to ct 26 ( hcea + ) loaded in balb / c mice. after vaccination with the cea gene - modified dc, the survival time of the mice vaccinated with ct26 + ( cea + ) ws prolonged more potently than that of the mice vaccinatd with other dcs
癌胚抗原（ carcinoebryonicantigen ， cea ）是一種研廠鄭州大學2002年碩士畢業論文轉染人癌胚抗原真核表達質粒的人樹突狀細胞的抗瘤作用究最為深入的腫瘤相關抗原（ tumorassociatiednigen ， taa ） ，在90的胃腸道腫瘤、 50的乳腺癌及70的非小細胞肺癌中有高水平的表達，是目前國際上公認的腫瘤標志物。 -
Porcine il - 12 ( pil - 12 ), also termed as natural killer cell stimulatory factor ( nksf ) and cytotoxic lymphocyte maturation factor ( clmf ), can induce some cytokines, particularly ifn -, from t and nk cells, as well as enhance the cytotoxic activity of these cells. its most critical role may be to initiate the development of cell - mediated immunity by promoting the differentiation of th1 cells from naive t cells
白細胞介素- 12 （ il - 12 ）又名nk細胞刺激因子（ nksf ）或細胞毒淋巴細胞成熟因子（ clmf ） ，能誘導t細胞和nk細胞產生ifn - ，並增強其細胞毒活性，它的關鍵作用是能誘導th0細胞分化為th1細胞以激發細胞免疫進程。 -
Objectives firstly to prepare the vaccine of human dcs and tumor cells transfectde with pcdna3 - cea, and to observe the induction of carcinoembryonic antigen ( cea ) - specific cytotoxic t - lymphocyte responses in vitro
用脂質體將cea表達質粒轉染人dc ，觀察其對cea表達陽性的腫瘤的特異性免疫作用。
