Objective To prepare oral CD226 DNA vaccine and observe its effect on immune function of mice. Methods CD226 gene was amplified by PCR using plasmid CD226-PCR2. 1-ToPo as a template,and inserted into vector pcDNA3. 1. The constructed recombinant plasmid pcDNA3. 1-CD226 was transiently transfected to CT-26 cells in mediation of LipofectamineTM2000. The expression of CD226 mRNA and protein were determined by RT-PCR,Western blot and flow cytometry. Plasmid pcDNA3. 1-CD226 was enveloped with LipofectamineTM2000...

CD226分子又称为血小板T细胞活化抗原l(platelet and T cell activation antigen 1,PTA1),主要表达于活化的T细胞、NK细胞和血小板等。CD226与其配体CDl55和CD112相互作用,参与血小板凝集、巨核细胞分化、内皮细胞黏附、CTL细胞和NK细胞的细胞杀伤等过程[1]。在发现早期CD226分
