Summary of "Development of a novel DNA based reverse genetic system for classic human astroviruses."

Human astroviruses (HAstVs) are a frequent cause of gastroenteritis in young children and immunocompromised patients. The current report describes a new approach to recover genetically defined HAstVs through the use of a reverse genetics system based on a single DNA plasmid. This plasmid, carrying the full-length virus genome under a T7 promoter, is directly transfected into cells expressing T7 RNA polymerase, resulting in the rapid and robust recovery of infectious HAstV. The efficiency of the system was tested with the generation of a chimeric astrovirus having the HAstV serotype 1 replication machinery and the capsid derived from a HAstV serotype 8 virus. This new system provides an efficient and reproducible method to deepen our knowledge of astrovirus biology.

Medical and Biotech [MESH] Definitions

A period in the human life in which the development of the hypothalamic-pituitary-gonadal system takes place and reaches full maturity. The onset of synchronized endocrine events in puberty lead to the capacity for reproduction (FERTILITY), development of secondary SEX CHARACTERISTICS, and other changes seen in ADOLESCENT DEVELOPMENT.

A ribonuclease activity that is a component of the HIV REVERSE TRANSCRIPTASE. It removes the RNA strand of the RNA-DNA heteroduplex produced by reverse transcription. Once the RNA moiety is removed a double stranded DNA copy of the HIV RNA can be synthesized.

Component of the NATIONAL INSTITUTES OF HEALTH. It was initially established to investigate the broad aspects of human development as a means of understanding developmental disabilities, including mental retardation, and the events that occur during pregnancy. It now conducts and supports research on all stages of human development. It was established in 1962.

A reverse transcriptase encoded by the POL GENE of HIV. It is a heterodimer of 66 kDa and 51 kDa subunits that are derived from a common precursor protein. The heterodimer also includes an RNAse H activity (RIBONUCLEASE H, HUMAN IMMUNODEFICIENCY VIRUS) that plays an essential role the viral replication process.

Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.
