antigen receptor 中文意思是什麼
-
Intervention of two different digestion methods on the expression of surface antigen alpha 6 integrin and transferrin receptor in epidermic cells
6整合素和轉鐵蛋白受體表達的干預 -
Effective activation of antigen - specific t cells not only requires the first signal transduction through t - cell receptor ( tcr ) binding with peptide - mhc complex on the antigen presenting cell ( apc ), but also needs the second signal, termed costimulation. costimulation critical to the degree and consequence of t cell activation is provided by interaction between soluble factors or cell - surface molecules on the t cell and on the apc
而t細胞的活化除需要t細胞受體（ tcr ）與抗原呈遞細胞（ antigenpresentingcell ， apc ）表面的抗原肽- mhc復合物結合所形成的第一信號外，還需要t細胞和apc表面的其它膜分子結合所提供的共刺激信號（亦稱第二信號或輔助刺激信號， costimulatorysignal ）的參與。 -
Cd 14 * monocytes or bone marrow derived hematopoietic progenitor cells cultured with granulocyte - macrophage colony - stimulating factor ( gm - csf ) and il - 4 differentiate into efficient apc with morphology and cell surface molecule expression typical of immature dc. it was demonstrated that a variety of factors ( such as lps, tnf - a, il - 1, monocyte - conditioned medium, and cd40 receptor cross - linking ) induce the maturation of immature dc to mature dc that are much more potent in activating t cells by increasing the expression of costimulatory molecules and cytokines, promoting the migration of dc to draining lymph nodes, and down - regulating the capacity of dc to capture and process antigen
在體外，外周血cd14 ~ +單核細胞和cd34 ~ +骨髓造血前體細胞在粒細胞-巨噬細胞集落刺激因子（ granulocyte - macrophagecolony - stimulatingfactor ， gm - csf ）和il - 4的共同作用下可分化為未成熟dc ，未成熟dc具有強大的攝取和處理抗原的能力，但其抗原提呈能力較弱；未成熟dc在炎性細胞因浙江大竿俗士學位論文潛廷平子汐ilq ， yfax病原成分汐lpsx單核細胞條件培養液或cd40l等作用下可分化為成熟dc 。 -
To activate t cells, one receptor responds to a specific foreign invader, or antigen, and another, cd28, signals a green light for an immune response
一般t細胞的活化，除了要有一個特定外來物（抗原）與細胞表面受體結合，還需要另一個受體蛋白cd28發出免疫反應的綠燈信號。
