Using Enzyme-Linked Aptamer Assay to Detect Hepatitis B Surface Antigen in Comparison to Enzyme-Linked Immunosorbent Assay

مجله دانشکده پزشکی اصفهان, 2018
Background: Clinical diagnostic kits for detecting hepatitis B are based on antibodies, and have inefficient sensitivity, stability, and cost. Therefore, researches about aptamers and using them instead of antibodies may make these defects up.

Hepatitis B surface antigen in hepatocellular carcinoma.

Japanese journal of cancer research : Gann, 1985
Hepatitis B surface antigen (HBs-Ag) was detected histologically (by victoria blue-nuclear fast red staining) in the liver in 20-40% of liver cirrhosis and/or hepatocellular carcinoma (hepatoma) cases. In hepatoma cases, HBs-Ag was usually found in non-cancerous areas of the liver.

Tracking the source of the hepatitis B virus-specific CD8 T cells during lamivudine treatment [PDF]

, 2003
Lamivudine treatment in chronic hepatitis B leads to the reconstitution of virus-specific T cells in the circulation, but it is not clear whether this is the preferential result of T cell efflux from the liver or lymph nodes.

Dual Blockade of LILRB1 and LILRB2 Enhances Antiviral Immune Responses in SIV Infection

Advanced Science, EarlyView.
Dual LILRB1/B2 blockade with mac20G10 reshapes myeloid activation during acute SIV infection by targeting LILRB1 and LILRB2 on myeloid cells. This treatment enhances CD80 expression on selected myeloid subsets and increases plasma IFN‐λ, IL‐8, and IL‐1RA.

Glycopeptide Composition of Hepatitis B Surface Antigen

Journal of General Virology, 1980
Three major polypeptides of hepatitis B surface antigen (HBsAg), with mol. wt. 22,000 (p22), 27,000 (p27) and 68,000 (p68), were separated by preparative SDS-PAGE. These three peptides as well as intact HBsAg were found to have almost identical amino acid compositions and carbohydrate was detected in p27 and p68 by PAS staining. Papain treatment of p68

Hepatitis B Virus Infection Among Antenatal Clinic Attendees at the Muhimbili National Hospital, Seroprevalence and Associated Factors [PDF]

, 2011
Hepatitis B virus (HBV) infection is a serious public health problem in sub-Saharan Africa. Vertical transmission is one of the modes of transmission. The risk of transmission increases if the mother is hepatitis B surface antigen (HBsAg) positive and ...

Chronic HBV Infection Disrupts CCL5‐Secreting cNK Cells and Attenuates Liver Accumulation and Activation of DCs and HBV‐Specific T Cells

Advanced Science, EarlyView.
ADORA2A activation suppresses NFκB‐dependent CCL5 production in cNK cells during chronic HBV infection, disrupting intrahepatic DC recruitment and HBV‐specific CD8+ T‐cell differentiation and function. Targeting the ADORA2A/NFκB/CCL5 axis restores antiviral immunity and facilitates HBV clearance.

Chemiluminescent Optical Fiber Immunosensor Combining Surface Modification and Signal Amplification for Ultrasensitive Determination of Hepatitis B Antigen

Sensors, 2020
Optical fiber based immunosensors are very attractive for biomarker detection. In order to improve the sensor response, we propose a promising strategy which combines porous-layer modification of the fiber surface and streptavidin-biotin-peroxidase nano ...

Hepatitis B virus in silvery gibbons (Hylobates moloch) [PDF]

, 2004
This research investigated a number of issues regarding hepatitis B virus (HBV) in the silvery gibbon (Hylobates moloch). Due to the relatively recent discovery of the virus in nonhuman primate populations, specific knowledge of the biological behaviour ...
