PYY

PYY,即肽YY,別名PYY3-36(指其C末端的36個氨基酸片段)。它是一種由腸道L細胞分泌的多肽激素,屬于胰高血糖素樣肽(GLP)家族成員,與GLP-1具有高度同源性。PYY在人體中由PYY基因編碼,主要在腸道內分泌細胞產(chǎn)生,尤其是回腸和結腸。PYY的作用機制主要通過與其特異性G蛋白偶聯(lián)受體NPY Y2受體(Y2R)和NPY Y4受體(Y4R)結合來發(fā)揮作用。PYY3-36片段是PYY的活性形式,它在腸道分泌后進入血液循環(huán),通過與Y2R結合,減緩胃排空速度,抑制食欲,從而減少食物攝入。此外,PYY還能通過影響腸道運動和分泌,參與調節(jié)腸道功能。PYY在生物學上的意義非常廣泛,它在能量平衡、體重調節(jié)、胰島素分泌和腸道穩(wěn)態(tài)中發(fā)揮重要作用。PYY通過減緩胃排空,增強飽腹感,有助于減少食物攝入和控制體重。在糖尿病治療中,PYY3-36通過促進胰島素和抑制胰高血糖素的分泌,有助于改善血糖控制。此外,PYY還參與調節(jié)腸道屏障功能和炎癥反應,對腸道健康具有保護作用。因此,PYY是代謝和消化系統(tǒng)研究中的一個重要分子,也是治療肥胖癥和糖尿病的潛在靶點。

PYY Antibody (CSB-PA12214A0Rb)

驗證數(shù)據(jù)

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.

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.
