The structure of hepatitis B virus. Hepatitis B virus is a member of the Hepadnavirus family. [11] The virus particle, called Dane particle [12] (), consists of an outer lipid envelope and an icosahedral nucleocapsid core composed of protein.
The structure of hepatitis B virus. Hepatitis B virus (HBV) is a member of the hepadnavirus family. [39] The virus particle consists of an outer lipid envelope and an icosahedral nucleocapsid core composed of core protein. These virions are 30–42 nm in diameter.
HBeAg is a hepatitis B viral protein, produced by the HBcAg reading frame. It is an indicator of active viral replication ; this means the person infected with Hepatitis B can likely transmit the virus on to another person (i.e. the person is infectious).
Hepadnaviruses, as their "hepa" name implies, infect liver cells and cause hepatitis. This is true not only of the human pathogen Hepatitis B Virus but also the hepadnaviruses that infect other organisms. The "adhesion" step of the dynamic phase—in which an exterior viral protein stably interacts with a host cell protein—determines cell ...
HBcAg (core antigen) is a hepatitis B viral protein. [ 1 ] [ 2 ] It is an indicator of active viral replication; this means the person infected with Hepatitis B can likely transmit the virus on to another person (i.e. the person is infectious).
The Hepatitis B virus (HBV) polymerase is a multifunctional enzyme, with both RNA-dependent and DNA-dependent polymerase functions, as well as an RNase H function. It acts on the HBV pre-genomic RNA (pgRNA) to reverse transcribe it to form a new rcDNA molecule within a new capsid.
The genome organisation of HBV; the genes overlap. ORF X, in yellow, encodes HBx. HBx is a hepatitis B viral protein. [1] [2] It is 154 amino acids long and interferes with transcription, signal transduction, cell cycle progress, protein degradation, apoptosis and chromosomal stability in the host.
In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale. The hepatic lobule is a building block of the liver tissue, consisting of a portal triad, hepatocytes arranged in linear cords between a capillary network, and a central vein.
