Results The adhering rate of PMNs to PMEC was obviously lowered by the adding of L-selectin mAb and sulfatide.
结果L-选择素单抗或硫苷脂能降低中性粒细胞与烧伤血清激活的PMEC间粘附率。
L-selectin is mainly expressed on leukocytes and mediates leukocytes rolling contact with microvascular endothelial cells.
选择素主要在白细胞表达，介导白细胞在微血管内皮细胞上的滚动接触。
But there is no differcence of the expression of L-selectin in gliomas and control group (P > 0.05 ) .
选择素L在胶质瘤组和对照组中的表达无统计学意义（P＞0.05）；
T cells' hybrid tumor cells which specifically metastasize to lymph node highly express L-selectin.
在T细胞杂交瘤中，转移到周围淋巴结的肿瘤细胞通常都有强的L-选择蛋白的表达。
Except for its role in adhesion, L-selectin can serve as a signal transduction molecule.
除具有黏附作用外，L -选择素还作为信号分子在黏附事件中发挥作用。
However, till now it is yet unknown how L-selectin and PSGL-1 initiate similar signaling pathways, nor any crosslinking between the two pathways has been found.
然而，目前还没有明确L -选择素和PSGL - 1如何引起相似的信号途径，也没有找到这两条信号通路的整合点。
Conclusion The recombinant human L-selectin protein can express with high efficiency in E. coli M15. The prepared polyclonal antibody has a high titer.
结论：人l -选择素蛋白可在M15大肠杆菌中高效表达，其多克隆抗体效价较高。
