ABSTRACT
Objective To investigate the inhibitive activities of hepatitis B immunoglobulin(HBIG)poly(butylcynaoacrylate)nanoparticles(HBIG-PBCA-NP)to hepatitis B surface antigen(HBsAg)and hepatitis B virus(HBV)DNA secretions using HBV infected cell model in vitro.Methods HepG 2.2.15 cells were cultured with media containing HBIG-PBCA-NP or HBIG for several days,or cultured with HBIG-PBC-NP and HBIG for 2 days and without HBIG-PBCA-NP and HBIG from day 3.The supernatants at different time points were collected for quantitative detection of HBsAg and HBV DNA.The comparisons between groups were done by variance analysis.Resalts Secretions of HBsAg and HBV DNA in supernatants of HepG2.2.15 cultured with 0.1-10.0 IU/mL of HBIG-PBCA-NP and HBIG were inhibited significantly compared with control group.HBsAg titers and HBV DNA levels in supernatants of HBIG-PBCA-NP group and HBIG group cultured with media without HBIG-PBCA-NP and HBIG kept decreasing at day 5 and 7,then rebounded at day 9 and 11.HBsAg titera in supernatants of 0.1,1.0,5.0 IU/mL HBIG-PBCA-NP group were all significantly different from those in HBIG group at day 9[(31.31±1.98)μg/L vs(40.62±2.99)μg/L,(23.79±1.31)μg/L vs(36.51±2.12)μg/L,(19.91±1.74)μg/L vs(33.03±1.65)μg/L;F=412.24,P<0.01].Couclusion HBIG-PBCA-NP can inhibit secretions of HgsAg and HBV DNA in vitro,which is more effective than HBIG.
