fc region 中文意思是什麼
fc region
解釋
fc區-
It is interesting that pma plus calcium ionophore a23187 can inhibit pma - induced pta1 expression, and this effect ca n ' t be reversed by calcmeurin inhibiter fk506. pta1 mabs can inhibit ctl activation and differentiation in mixed lymphocyte culture system when added at the beginning of the culture but can induce platelet activation and aggregation in the fc dependent manner. in 1997, pta1 cdna was cloned from cdna library of tpa activated jurkat cells, which belongs to immunoglobulin superfamily ( igsf ) with two v - like domains of extracelluar region of pta1
Il - 2 、 tnf - 、 pma可以使t細胞pta1表達上調， tgf -可以下調pta1的表達，而pma加上鈣離子載體a23187可以顯著抑制pma的上調作用，且這種抑制作用不被calcineurin抑制劑fk506所逆轉， 1997年burns教授從pma活化的jurkat細胞cdna文庫中克隆了pta1cdna全長，證實pta1是一個新分子，屬于免疫球蛋白超家族，胞膜外區有兩個v樣結構域。 -
Huctla4 - lg, " one of the most potent in1n1unosuppressive molecules, is a soluble recombinant fusion protein ( molecu1ar weight of approximately 92 kd ) consisting of the extracellular domain of human ctla - 4 and a fragment ( hinge and constant region ) of the fc portion of human iggl. it strongly adheres to the b7 molecule to block the cd28 - mediated costimulatory signal, resulting in inhibition of in vitro and in vivo immune response
可溶性重組融合蛋白huctla4 - ig是一種新穎的免疫抑制劑，分子量約為92kd ，由人ctla - 4分子的胞膜外區與人igg1的fc段（鉸鏈區與恆定區）融合形成，能牢固地與b7分子結合，阻斷cd28介導的共刺激信號，導致免疫反應的抑制。 -
Ctla4ig fusion protein was expressed by genetically fusing the dna fragment encoding 1 - 125 amino acid residues of ctla4 extracellular domain with dna fragment encoding an igg fc region. its in functional region is the extracellular domain of ctla4
Ctla4ig融合蛋白是通過基因重組技術將編碼ctla4胞外區1 - 125個氨基酸序列的dna片段與編碼iggfc段的dna片段融合后表達生成，其功能區是ctla4胞外區。
