*w59BO&M4 1. 淋巴細胞歸巢（lymphocyte homing）：是指淋巴細胞的定向游動，包括淋巴干細胞向中樞淋巴器官歸巢，成熟淋巴細胞向外周淋巴器官歸巢，淋巴細胞再循環，以及淋巴細胞向炎癥部位遷移。其分子基礎是淋巴細胞歸巢受體與內皮細胞上地址素之間的相互作用。 a` 95eL} 2. 淋巴細胞歸巢受體（lymphocyte homing receptor，LHR）：是指存在于淋巴細胞表面的某些粘附分子，如：L-selectin， CLA， LFA-1， VLA-4， CD44， α4β7等。他們可以與血管內皮細胞上相應的地址素粘附分子相互作用，介導淋巴細胞的歸巢。 O,]t.亚洲国产精品va在线观看麻豆
