Escaping high viral load exhaustion: CD8 cells with altered tetramer binding in chronic hepatitis B virus infection [PDF]

, 2002
Deletion, anergy, and a spectrum of functional impairments can affect virus-specific CD8 cells in chronic viral infections. Here we characterize a low frequency population of CD8 cells present in chronic hepatitis B virus (HBV) infection which survive in

Modulation of the CD8+-T-cell response by CD4+ CD25+ regulatory T cells in patients with Hepatitis B virus infection [PDF]

, 2005
CD4+ CD25+ regulatory T cells have been shown to maintain peripheral tolerance against self and foreign antigens. In this study we analyzed the effect of circulating CD4+ CD25+ T cells on CD8+-T-cell responses of patients with chronic and resolved ...

Hepatitis B Antigen in Saliva

The Tohoku Journal of Experimental Medicine, 1973
Hepatitis B antigen (HB Ag) detectable only by means of rvdioimmnnoassay was found in saliva of 5 out of 36 mentally retarded children in an institution. Electron microscopic study of purified antigen in saliva revealed the presence of tubular and small Dane particles.

Electrofocusing of Hepatitis B Antigen

Journal of General Virology, 1973
Summary Hepatitis B (Australia) antigen was isolated from normal serum proteins by gel filtration and electrofocusing. The latter technique revealed a heterogeneity of the small spherical particles associated with hepatitis B antigen activity, there being a variance in determined isoelectric points according to the serological subtype studied ...

Humoral Immune Memory to Hepatitis B Vaccine after Primary Vaccination of Children and Adolescents in Assiut, Egypt

Oman Medical Journal, 2020
Objectives: We sought to assess the prevalence of hepatitis B virus (HBV) seroprotection among vaccinated children in the Assiut governorate, Egypt, and assess a booster dose immune memory response among non-seroprotected children.

Baseline quantitative HBcAb strongly predicts undetectable HBV DNA and RNA in chronic hepatitis B patients treated with entecavir for 10 years

Scientific Reports, 2021
The predictive effect of quantitative anti-hepatitis B core on double-negative HBV DNA and RNA remains unstudied. We observed dynamic changes in this measure in chronic hepatitis B patients receiving entecavir for 10 years, evaluating its predictive ...

Hepatitis B antigen, hepatitis B antibody, and subtypes in leprosy [PDF]

Infection and Immunity, 1977
The prevalence of hepatitis B antigen (HBsAg), hepatitis B antibody (HBsAb), and subtypes in 242 cases of leprosy is reported. Patients were divided into three subgroups, lepromatous (174), tuberculoid (55), and borderline (13). A total of 131 patients were tested on admission; the remaining 111 had been institutionalized for a period of 3 months or ...
