| I. Background | |
| 
				 CCR5(趨化因子受體 5 或趨化因子 C-C 亞族受體 5),也稱(chēng)為 CD195,是一種 G蛋白 偶聯(lián)受體,屬于整合型膜蛋白的 β 趨化因子受體家族成員。CCR5 主要與 Gα i/o 和 Gα q/11 偶聯(lián),在樹(shù)突狀細(xì)胞、T 細(xì)胞、巨噬細(xì)胞、嗜酸性粒細(xì)胞、小膠質(zhì)細(xì)胞和髓系抑制細(xì)胞上 表達(dá),并由多種配體(CCL3、CCL3L1、CCL4、CCL5、CCL8、CCL11、CCL13 和 CCL16) 激活,以促進(jìn)趨化性和免疫細(xì)胞活化。 
			巨噬細(xì)胞和樹(shù)突狀細(xì)胞分泌 CCR5 依賴(lài)性促炎細(xì)胞因子可激活適應(yīng)性免疫反應(yīng)?;罨?的 CD4+ T 細(xì)胞分泌 CCR5 依賴(lài)性 IL-2 可誘導(dǎo)效應(yīng) T 細(xì)胞、記憶 T 細(xì)胞和調(diào)節(jié)性 T 細(xì)胞的 增殖和活化。 CCR5 是加速募集效應(yīng)和記憶 CD8+ T 細(xì)胞至感染部位所必需的。CCR5 是 HIV 進(jìn)入免疫細(xì)胞的輔助受體。CCR5 可與多種配體任意結(jié)合,從而啟動(dòng)包括引導(dǎo)遷移在 內(nèi)的細(xì)胞信號(hào)傳導(dǎo)。  |

				 Concentration-dependent stimulation of intracellular calcium mobilization by MIP-1α in CCR5/Gα16/CHO and Gα15/CHO cells   Figure 1. MIP-1α-induced concentration-dependent stimulation of intracellular calcium mobilization in CCR5/Gα16/CHO and Gα15/CHO cells. The cells were loaded with Calcium-4 prior to stimulation with an CCR5 receptor agonist, MIP-1α. The intracellular calcium change was measured by FlexStation.  |
