背景资料:PEN2 Antibody: PEN2, in addition to presenilin, nicastrin, and APH-1 forms the gamma-secretase protein complex, a membrane-bound aspartyl protease that can cleave certain proteins at peptide bonds buried within the hydrophobic environment of the lipid bilayer. This cleavage is responsible for a key step in signaling from several cell-surface receptors and is thought to be required for the generation of the neurotoxic amyloid peptides that are central to the pathogenesis of Alzheimer's disease. Like the tumor necrosis factor-alpha-converting enzyme (TACE) and the beta-site cleavage enzyme (BACE) protease families, gamma-secretase will cleave the amyloid precursor protein (APP), but within the intramembrane region of APP, resulting in either the non-toxic p3 (from the alpha and gamma cleavage site) or the toxic Abeta amyloid peptide (from the beta and gamma cleavage site). It is thought that accumulation of the Abeta peptide is the precursor to Alzheimer's disease.

文献和实验Nature 重磅:林圣彩院士团队七年攻坚!首次破解「神药」二甲双胍作用靶点之谜
Nature 杂志发表了题为 Low-dose metformin targets the lysosomal AMPK pathway through PEN2 上的文章,通过化学合成二甲双胍的探针去「钓取」其结合靶点,然后再通过质谱分析进行解析,最终发现了治疗剂量的二甲双胍直接发挥作用的靶点及其内在分子机制,为糖尿病的治疗,乃至抗肿瘤、抗衰老的药物研发和应用提供了新的思路,这次历史性突破有望成为糖尿病药物治疗史上的里程碑事件。 图片来源:Nature 主要研究内容 PEN2 与二甲双胍结合
在免疫反应方面,基于抗原的刺激在体内形成、并与抗原作特异性结合的蛋白质之总称。其化学实质是免疫球蛋白。抗体,按照抗原抗体反应的类型可分别称为沉淀素、凝集素、溶血素、溶菌素、抗毒素、中和抗体等,但这些并不等于有相应的不同抗体存在,一般多只表明抗体反应的多样性而已。抗体在血清中含量最多(体液抗体=humoral antibody);含有某特定抗体的血清称为抗血或免疫血清。
机体在抗原物质刺激下,由B细胞分化成的浆细胞所产生的、可与相应抗原发生特异性结合反应的免疫球蛋白。因为最初有人用电泳证明血清中抗体活性在γ球蛋白部分,故曾把抗体统称为两种(γ)球蛋白。后来证明,抗体并不都在γ区;而且位于γ区的球蛋白,也不一定都具有抗体活性。1964年,世界卫生组织举行专门会议,将具有抗体活性以及与抗体相关的球蛋白统称为免疫球蛋白(Ig)。如骨髓瘤蛋白,巨球蛋白血症、冷球蛋白血症等患者血清中存在的异常免疫球蛋白以及“正常人”天然存在的免疫
