Angioimmunoblastic T-Cell Lymphoma (AITL) is a rare and aggressive type of nodal or soft tissue lymphoma. Nodal lymphomas are restricted to lymph nodes, and generally do not enter the blood stream, until later stages of the disease.
Hepatitis A virus is a picornavirus, a small single strand RNA virus; hepatitis B virus belongs to the hepadnavirus family of double stranded DNA viruses; hepatitis C virus is a flavivirus, a single stand RNA virus; hepatitis E, also an RNA virus, is similar to a calicivirus.uman hepatitis B virus (figure 3) is the prototype virus of the hepadnavirus family and causes serum hepatitis. HBV has a diameter of about 40nm. It infects humans and chimpanzees but there are closely related members of this family that infect other mammals and birds. HBV is a DNA virus and is enveloped.
In order to understand what happens when a person is infected with hepatitis B it is helpful to know more about the virus. This section attempts to convey information about the hepatitis B virus, how it reproduces and the human bodies response to the virus. This one chapter could fill a text book, or more, and so the information is simplified. Hepatitis B is a DNA Virus of the hepadnaviridae family of viruses. It replicates within infected liver cells (hepatocytes ). The infectious (Dane) particle consists of an inner core plus an outer surface coat.
