膜抗原受體 的英文怎麼說
中文拼音 [mókàngyuánshòutǐ]
膜抗原受體
英文
membrane antigen receptor-
It has a high entrapment efficiency of 98. 3 %, particle size distributing within 5 - 7u m, viscid coefficient of 1432 centipoise. antigen was stable after multiple emulsion treated with gastric juice for 0. 5 - 6h. study on distribution in vivo of me revealed that me could stay for a long time in stomach and that antigen concentration in mesentery was increased with time and reached peak at 24h
疫苗復乳的包封率為98 . 3 % ，粒徑主要分佈於2 ~ 10pm之間，集中於5一7pm ，粘度為1432厘泊，體內分佈實驗顯示， 6h胃中的抗原濃度仍很高，腸系膜淋巴結中的放射量24h最高，與胃液作用0 . 5 ~ 6小時復乳中的抗原不受影響，口服免疫小鼠后明顯提高了rhp疫苗的免疫應答水平。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。By pulling receptors away from their surface membrane during signaling, t cells can prevent themselves from being lethally overstimulated by too much antigen
在溝通過程中， t細胞會將受體抽離細胞膜表面，以避免因受到過多抗原的刺激而死於非命。
