| HIV envelope protein gp160 | An envelope protein of the human immunodeficiency virus that is encoded by the HIV env gene. It has a molecular weight of 160,000 kD and contains numerous glycosylation sites. It serves as a precursor for both the HIV envelope protein gp120 and the HIV envelope protein gp41. (12 Dec 1998) |
|---|---|
| HIV envelope protein gp41 | Transmembrane envelope protein of the human immunodeficiency virus which is encoded by the HIV env gene. It has a molecular weight of 41,000 and is glycosylated. The n-terminal part of gp41 is thought to be involved in cell fusion with the CD4 antigens of t4 lymphocytes, leading to syncytial formation. Gp41 is one of the most common HIV antigens detected by immunoblotting. (12 Dec 1998) |
| HIV infections | Includes the spectrum of human immunodeficiency virus infections that range from asymptomatic seropositivity, thru aids-related complex (arc), to acquired immunodeficiency syndrome (aids). (12 Dec 1998) |
| HIV integrase | <enzyme> Enzyme of the human immunodeficiency virus that is required to integrate viral DNA into cellular DNA in the nucleus of a host cell. HIV integrase is a DNA nucleotidyltransferase encoded by the pol gene. Registry number: EC 2.7.7.- (12 Dec 1998) |
| HIV integrase inhibitors | Inhibitors of HIV integrase, an enzyme required for integration of viral DNA into cellular DNA. (12 Dec 1998) |
| HIV protease | <enzyme> Enzyme of the human immunodeficiency virus that is required for post-translational cleavage of gag and gag-pol precursor polyproteins into functional products needed for viral assembly. HIV protease is an aspartic protease encoded by the amino terminus of the pol gene. Registry number: EC 3.4.23.- (12 Dec 1998) |
| HIV protease inhibitors | Inhibitors of HIV protease, an enzyme required for production of proteins needed for viral assembly. (12 Dec 1998) |
| HIV seronegativity | Immune status consisting of non-production of HIV antibodies, as determined by various serological tests. (12 Dec 1998) |
| HIV seropositivity | Development of neutralizing antibodies in individuals who have been exposed to the human immunodeficiency virus (HIV/HTLV-III/lav). (12 Dec 1998) |
| HIV seroprevalence | Studies of the number of cases where human immunodeficiency virus (HIV) is present in a specific population at a designated time. The presence in a given individual is determined by the finding of HIV antibodies in the serum (HIV seropositivity). (12 Dec 1998) |
| HIV test | <investigation> A test which is performed on a standard venipuncture blood specimen which detects the presence of antibodies to HIV (virus). This test may not be positive for 3 to 6 months after infection with HIV. (27 Sep 1997) |
| HIV wasting syndrome | <syndrome> Involuntary weight loss of greater than 10 percent associated with intermittent or constant fever and chronic diarrhoea or fatigue for more than 30 days in the absence of a defined cause other than HIV infection. A constant feature is major muscle wasting with scattered myofibre degeneration. A variety of aetiologies, which vary among patients, contributes to this syndrome. (12 Dec 1998) |
