HLA-DRB1, DQA1 and DQB1 Alleles and Hap-lotypes Frequencies in Iranian Healthy Adult Responders and Non-Responders to Recombi-nant Hepatitis B Vaccine
Background: Different studies have demonstrated that a small proportion of healthy individuals receiving the hepatitis B (HB) vaccine do not produce protective levels of anti-HB antibody, a phenomenon which could be linked to certain human leukocyte an-tigen (HLA) class-II alleles or haplotypes. Objectives: The present study was under-taken to determine the frequency of HLA class-II alleles in ...
متن کاملDistribution of Circulating Immune Cells in Responder and Non-Responder Individuals to Hepatitis B Vaccine
Unresponsiveness to hepatitis B surface antigen (HBsAg) has been shown to be associated with dysfunction of the presenting cells (APC) and defect in the specific B-lymphocyte and/or T-lymphocyte repertoires. Direct determination of the frequency of specific T-lymphocytes together with complementary analysis of the naive circulating immune cells could provide valuable information about the cel...
متن کاملThe factors influencing the immune response to hepatitis B vaccine and persistence of the protection.
Hepatitis B virus (HBV) infection and its sequelae which include cirrhosis and hepatocellular carcinoma is a major public health problem throught the world.The WHO strategy for effective control of HBV infection is vaccination with the surface antigen of virus(HBsAg).The results obtained from a large number of studies demonstrated that the vaccine induces a protective antibody resonse (anti-HB...
متن کاملDownregulation of IL-12 Production in Healthy Non-Responder Neonates to Recombinant Hepatitis B Vaccine
A proportion of healthy neonates and adults fail to develop a protective antibody response to recombinant hepatitis B (HB) vaccine. Unresponsiveness to vaccination could be attributed to defect in a number of immunological regulatory mechanisms. In this study, IL-12 was quantitated in culture supernatant following in vitro stimulation of peripheral blood mononuclear cells isolated from a group ...
