PYY

PYY,即肽YY,别名PYY3-36(指其C末端的36个氨基酸片段)。它是一种由肠道L细胞分泌的多肽激素,属于胰高血糖素样肽(GLP)家族成员,与GLP-1具有高度同源性。PYY在人体中由PYY基因编码,主要在肠道内分泌细胞产生,尤其是回肠和结肠。PYY的作用机制主要通过与其特异性G蛋白偶联受体NPY Y2受体(Y2R)和NPY Y4受体(Y4R)结合来发挥作用。PYY3-36片段是PYY的活性形式,它在肠道分泌后进入血液循环,通过与Y2R结合,减缓胃排空速度,抑制食欲,从而减少食物摄入。此外,PYY还能通过影响肠道运动和分泌,参与调节肠道功能。PYY在生物学上的意义非常广泛,它在能量平衡、体重调节、胰岛素分泌和肠道稳态中发挥重要作用。PYY通过减缓胃排空,增强饱腹感,有助于减少食物摄入和控制体重。在糖尿病治疗中,PYY3-36通过促进胰岛素和抑制胰高血糖素的分泌,有助于改善血糖控制。此外,PYY还参与调节肠道屏障功能和炎症反应,对肠道健康具有保护作用。因此,PYY是代谢和消化系统研究中的一个重要分子,也是治疗肥胖症和糖尿病的潜在靶点。

PYY Antibody (CSB-PA12214A0Rb)

验证数据

CSB-PA12214A0Rb

IHC image of CSB-PA12214A0Rb diluted at 1:200 and staining in paraffin-embedded human small intestine tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.
