GLP2R/CRE-Luc/HEK293
| I. Background | |
G 蛋白偶聯受體(GPCR) 是跨膜蛋白受體，其特征是配體數量可變，包括內源性神經遞質和激素，也包括外源性天然和人工化合物。激動劑與受體結合后會觸發信號通路的激活；而拮抗劑則會阻礙激動劑介導的受體激活。反向激動劑除像拮抗劑一樣干擾激動劑外，還會抑制受體的組成活性。 GLP2 受體 (GLP2R) 是 G 蛋白偶聯受體超家族成員，與胰高血糖素受體 ( GLP1 受體)密切相關。胰高血糖素樣肽-2 (GLP2) 是由腸道腸內分泌細胞產生的 33 個氨基酸的胰高血糖素原衍生肽。GLP-2 通過特定的 G s 蛋白偶聯受體（GLP-2R）發揮作用，維持腸道穩態和屏障功能，減緩胃排空和腸道蠕動，改善粘膜血流和營養吸收，增強免疫防御能力。 | |
