RESUMEN
<p><b>OBJECTIVE</b>To investigate the effect of allitridin injection on the expression of human cytomegalovirus (HCMV) immediate-early antigens (IEAs including IE72 and IE86) in human embryonic lung cells.</p><p><b>METHOD</b>HCMV AD 169 Virus strain infected cell model (MOI = 2.5 and 0.25, respectively) were established, and then treated with ICm5 and MTC doses of allitridin. Western blot was used to analyze the of IE72 and IE86 expression after the treatment, ganciclovir(GCV, IC50 and 2.3 x IC50) treatment as control.</p><p><b>RESULT</b>No matter what kind of MOI was used, both IE86 and IE72 antigens' expression was effectively suppressed by allitridin treatment, and the inhibitory rate of IE86 was almost twice of IE72's. Compared with GCV, allitridin had stronger inhibitory effect on IE86 expressing, although its efficacy on IE72 was weaker than GCV.</p><p><b>CONCLUSION</b>Allitridin could suppress the expression of IE72 and IE86, especially for IE86 expressing, maybe it is ore of key role in the mechanism of allitridin against HCMV.</p>
