Since 1984, studies from almost every branch of modern biology have filled in many gaps in our knowledge of human immunodeficiency virus type 1 (HIV-1). This review focuses on studies of biodiversity and bioseparation of HIV-1 envelope glycoproteins from the vaccine development point of view. It presents an updated picture of different systems for producing either native or recombinant HIV-1 envelope glycoproteins for the preparation of vaccine candidates. The prevention of HIV-1-associated disease is highly relevant to the abrogation of the neoplastic processes associated with this pathogen.

UI	MeSH Term	Description	Entries
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000163	Acquired Immunodeficiency Syndrome	An acquired defect of cellular immunity associated with infection by the human immunodeficiency virus (HIV), a CD4-positive T-lymphocyte count under 200 cells/microliter or less than 14% of total lymphocytes, and increased susceptibility to opportunistic infections and malignant neoplasms. Clinical manifestations also include emaciation (wasting) and dementia. These elements reflect criteria for AIDS as defined by the CDC in 1993.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D015497	HIV-1	The type species of LENTIVIRUS and the etiologic agent of AIDS. It is characterized by its cytopathic effect and affinity for the T4-lymphocyte.	Human immunodeficiency virus 1,HIV-I,Human Immunodeficiency Virus Type 1,Immunodeficiency Virus Type 1, Human
D015686	Gene Products, env	Retroviral proteins, often glycosylated, coded by the envelope (env) gene. They are usually synthesized as protein precursors (POLYPROTEINS) and later cleaved into the final viral envelope glycoproteins by a viral protease.	env Gene Products,env Polyproteins,env Protein,env Antigens,env Glycoproteins,env Polyprotein,Antigens, env,Polyprotein, env,Polyproteins, env
D015699	HIV Envelope Protein gp120	External envelope protein of the human immunodeficiency virus which is encoded by the HIV env gene. It has a molecular weight of 120 kDa and contains numerous glycosylation sites. Gp120 binds to cells expressing CD4 cell-surface antigens, most notably T4-lymphocytes and monocytes/macrophages. Gp120 has been shown to interfere with the normal function of CD4 and is at least partly responsible for the cytopathic effect of HIV.

D015752	Genes, env	DNA sequences that form the coding region for the viral envelope (env) proteins in retroviruses. The env genes contain a cis-acting RNA target sequence for the rev protein (	HIV rev-Responsive Element,env Genes,rev-Responsive Element,env Gene,Element, HIV rev-Responsive,Element, rev-Responsive,Elements, HIV rev-Responsive,Elements, rev-Responsive,Gene, env,HIV rev Responsive Element,HIV rev-Responsive Elements,rev Responsive Element,rev-Responsive Element, HIV,rev-Responsive Elements,rev-Responsive Elements, HIV

D017720	Molecular Epidemiology	The application of molecular biology to the answering of epidemiological questions. The examination of patterns of changes in DNA to implicate particular carcinogens and the use of molecular markers to predict which individuals are at highest risk for a disease are common examples.
