ii antigen 中文意思是什麼
-
Exosomes derived from human intestinal epithelial cell ( iec ) could be released from apical and basolateral sides and expressed mhc class i molecules, cd26, cd63 in basal conditions besides mhc class ii in inflammatory conditions. the data showed exosomes might be a mechanism of oral tolerance. exosome - like vesicles isolated from rat iec line, which were pulsed by antigens, were shown to induce antigen - spec
模型的建立和exosomes的分離與純化我們利用一種c57bl / 6小鼠的3lllewis肺癌細胞系作模型，將3ll細胞皮下注射到c57bl / 6小鼠，待3周時無菌取出腫瘤組織，剪碎後用dmem加10 %的血清在37 ， 5 %的czo中培養， 30小時后收集培養上清。 -
Constitutive expression of class ii mhc is restricted to " professional " antigen - presenting cells but can be induced on various tissues by gamma interferon
Mhc -類的組成型表達僅限於「專職性」抗原提呈細胞，但細胞因子如ifn -可引起誘導型類分子表達。 -
Interferon - is an antiviral cytokine produced by activated t cell and nk cell. it upregulated mhc ii antigen expression, influenced the cellular and humoral immune response and has pleiotropic regulatory effects on immune system. one gene was amplified by reverse transcription - polymerase chain reaction ( rt - pcr ) in splenocytes which was stimulated with cona for 24 hours
-干擾素（ interferon - ， ifn - ）主要由活化的t細胞及nk細胞產生，具有抗病毒作用，也具有上調mhc （ majorhistocompatibilitycomplex ， mhc ）類抗原分子的表達等作用，是影響機體細胞免疫和體液免疫反應的一類具有多種調節效應的細胞因子。 -
As c ii ta is a single gene or protein that affects a large family of genes, it represents an ideal target for intervention in the class ii antigen presentation pathway, for immune suppression in transplantation and autoimmumty
作為影響一個大基因家族的單個基因或蛋白質， c ta是對mhc -類的抗原提呈過程進行干預的理想靶點，可以在自身免疫損傷和移植排異過程中進行免疫抑制干預。
