Immune response to hepatitis B surface antigen [PDF]

open access: yesInfection and Immunity, 1975
A total of 69 persons were investigated for assessment of cell-mediated and humoral immunity to hepatitis B surface antigen (HBsAg). Three groups, each consisting of 20 normal persons, 20HBsAg carriers, and 20 convalescent hepatitis B patients, were studied for HBsAg, anti-HBs, and leukocyte migration inhibition with purified HBsAg. Sequential sampling

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

open access: yesSensors, 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 ...

Glycopeptide Composition of Hepatitis B Surface Antigen

open access: yesJournal 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

Implantable Microarray Patch: Engineering at the Nano and Macro Scale for Sustained Therapeutic Release via Synthetic Biodegradable Polymers

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This review focuses on the application of synthetic biodegradable microarray patches (MAPs) in sustained drug delivery. Compared to conventional MAPs which release drugs into the skin in an immediate manner, these implantable MAPs release drugs into skin microcirculation gradually as the biodegradable polymers degrade, thus offering sustained release ...

Anticodon Engineered Transfer RNA (tRNASUAG) Inhibits Hepatitis B Virus Replication by Promoting the Degradation of Core Protein

open access: yesAdvanced Science, EarlyView.
This study employed tRNASUAG, an anticodon‐engineered tRNA (ACE‐tRNA), to introduce a phosphorylatable serine into the C‐terminal domain of HBc by reading through its stop codon, thereby potentially promoting the ubiquitin‐proteasome degradation of HBc, and subsequently inhibiting HBV replication. Through a tRNASUAG‐gHBV1‐tRNASUAG‐gHBV2‐tRNASUAG tandem
