概述
Interferon- gamma(IFN-γ),also known as Type II interferon or immune interferon,is a cytokine produced primarily by T -lymphocytes and natural killer cells.The protein shares no significant homology with IFN-β or the various IFN- α family proteins.Mature IFN-γ exists as noncovalently-linked homodimers.IFN-γ was originally characterized based on its antiviral activities.The protein also exerts antiproliferative,immunoregulatory and proinflammatory activities and is thus important in host defense mechanis ms.IFN-γ induces the production of cytokines,upregulates the expression of class I and II MHC antigens,Fc receptor and leukocyte adhesion molecules.It modulates macrophage effector functions,influences isotype switching and potentiates the secretion of immunoglobulins by B cells.Additionally,IFN-γ augments TH1 cell expansion and may be required for TH1 cell differentiation.Equine IFN-γ shares 73%~82%amino acid sequence identity with bovine,canine,feline,and porcine IFN-γ and 42%~64%with cotton rat,human,murine,rat,and rhesus macaque IFN-γ.

文献和实验人γ干扰素ELISA试剂盒应用双抗体夹心法测定标本中人γ干扰素(IFN-γ)水平。用纯化的人γ干扰素(IFN-γ)抗体包被微孔板,制成固相抗体,往包被单抗的微孔中依次加入γ干扰素(IFN-γ),再与HRP标记的γ干扰素(IFN-γ)抗体结合,形成抗体-抗原-酶标抗体复合物,经过彻底洗涤后加底物TMB显色。TMB在HRP酶的催化下转化成蓝色,并在酸的作用下转化成最终的黄色。颜色的深浅和样品中的γ干扰素(IFN-γ)呈正相关。用酶标仪在450nm波长下测定吸光度(OD值),通过标准曲线计算样品中人
与可溶性蛋白抗原反应的特异性Th克隆的制备需体内致敏,以及需要同系脾细胞作为抗原提呈细胞。有两种类型的辅助T细胞,即分泌IL-2的Th1和分泌IL-4的Th2,前者在克隆时需加入IFN-γ。 材料和试剂: 1. 免疫用动物; 2. 蛋白抗原和完全福氏佐剂(CFA); 3. 完全RPMI-1640培养液; 4. 生长因子的来源:可用ConA刺激上清或MLC培养上清,另外亦可用重组淋巴因子作为IL-2和IFN-γ的来源; 5. 动物
尘螨性变应原抗原表位的研究对变态反应的调节及治疗的可能性 (1)选择向Thl细胞 免疫应答发展多肽的原则:大剂量皮下注射变应原3~5年,可导致Thl细胞因子的产生;多价特异性多肽及重组变应原使用,使之避免可能产生IgE相关的效应途径。Thl细胞导向佐剂的使用:口服、鼻滴、舌下给药高剂量多肽均可使特异性抗原-Th2细胞产生耐受;使用能选择性诱导产生几-12的APC特异性变应原,如蜂毒磷酸化A2特异性多肽及第1类变应原(Feld-1)特异性多肽;DNA疫苗可诱导IFN-γ的T
