LCK
LCK,全稱為淋巴細胞特異性蛋白酪氨酸激酶,常見別名有淋巴細胞激酶、p56lck、Lck 激酶,主要表達于 T 淋巴細胞與自然殺傷細胞中,在胸腺及外周免疫器官分布豐富。它參與 T 細胞的發育成熟與免疫活化過程,協助識別抗原并推動免疫應答啟動,對維持機體正常免疫防御功能起到關鍵作用。
LCK表達或活性異常與多種疾病密切相關,過度激活易誘發類風濕關節炎、多發性硬化等自身免疫病,異常調控還會促進 T 細胞白血病、淋巴瘤等血液系統腫瘤的增殖與進展。目前針對 LCK 的小分子抑制劑已成為免疫疾病與腫瘤研究的熱點,多款候選藥物進入臨床前及早期臨床階段,通過調節其活性抑制異常免疫反應與腫瘤生長,為相關疾病治療提供新的策略。

Overlay Peak curve showing jurkat cells stained with CSB-RA583933A0HU (red line) at 1:100. The cells were fixed in 4% formaldehyde and permeated by 0.2% TritonX-100 for 10min. Then 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1ug/1*106cells) for 45min at 4℃. The secondary antibody used was FITC-conjugated goat anti-rabbit IgG (H+L) at 1/200 dilution for 35min at 4℃.Control antibody (green line) was Rabbit IgG (1ug/1*106cells) used under the same conditions. Acquisition of >10,000 events was performed.
