Therefore, this study was designed to analyze the role of Lck in IFN-alpha signaling by using the Jurkat, JCam (an Lck -defective cell line derived from Jurkat ), and JCam/ Lck ( JCam cells with Lck restored).
 ( cell line: JCam/ Lck, None) , ( cell line: Jurkat, None) , ( protein: Lck, None) , ( cell line: Lck -defective cell line, None) , ( protein: Lck, None) , ( protein: Lck, None) , ( protein: IFN-alpha, None) , ( protein: Lck, None) , ( cell line: JCam cells, None)
