|       趨化因子是一類炎性細(xì)胞因子,具有調(diào)節(jié)細(xì)胞遷移、粘附、吞噬作用、細(xì)胞因子分泌、 增殖和細(xì)胞凋亡的能力。越來越多的證據(jù)表明,趨化因子及其受體在穩(wěn)態(tài)和炎癥條件下在 調(diào)節(jié)樹突狀細(xì)胞遷移以及穩(wěn)態(tài)和炎癥功能方面發(fā)揮著重要作用。 CXCR2(C-X-C 趨化因子受體 2)是 G 蛋白偶聯(lián)受體(GPCR)家族成員,屬于 CXC 趨化因子受體亞家族,廣泛參與中性粒細(xì)胞趨化、炎癥反應(yīng)及腫瘤微環(huán)境調(diào)控。CXCR2 通 過結(jié)合多種趨化因子(如 CXCL1、CXCL2、CXCL8/IL-8)激活下游信號,在免疫應(yīng)答、 組織修復(fù)及病理過程中發(fā)揮關(guān)鍵作用。相較于 CXCR1,CXCR2 配體結(jié)合范圍更廣(包括 CXCL1-3、CXCL5-8),且在炎癥性疾病和癌癥中表現(xiàn)出更強的促血管生成及免疫抑制特性。  |

      CXCR2 β-Arrestin CHO 報告基因藥靶模型很好的模擬了體內(nèi) CXCR2/β-Arrestin 的信號轉(zhuǎn)導(dǎo)過程,原理見下圖當(dāng)缺乏配體刺激時,β-Arrestin 不與 CXCR2 結(jié)合,融合β- Arrestin 的熒光素酶處于失活構(gòu)象,當(dāng) CXCR2 遭遇配體刺激時,融合熒光素酶報告基因的 β-Arrestin 被招募,使熒光素酶報告基因處于激活狀態(tài),加入其底物后發(fā)光信號增強。![]() Figure 1.
