Virome
|
D000083422 |
[All of the VIRUSES that exist within a particular biological niche such as an organism or specific location of the organism, soil, a body of water, etc.
] |
|
Virophages
|
D000071819 |
[Circular, double-stranded DNA viruses that invade giant DNA viruses (GIANT VIRUSES) which infect eukaryotes.
] |
|
Viroporin Proteins
|
D000086082 |
[Viral proteins that assemble into oligomeric ION CHANNELS which can facilitate the transfer of viral materials across the CELL MEMBRANE.
] |
|
Virosomes
|
D022701 |
[Semi-synthetic complex derived from nucleic-acid free viral particles. They are essentially reconstituted viral coats, where the infectious nucleocapsid is replaced by a compound of choice. Virosomes retain their fusogenic activity and thus deliver the incorporated compound (antigens, drugs, genes) inside the target cell. They can be used for vaccines (VACCINES, VIROSOME), drug delivery, or gene transfer.

Virtual Reality
|
D000076142 |
[Using computer technology to create and maintain an environment and project a user's physical presence in that environment allowing the user to interact with it.
] |
|
Virtual Reality Exposure Therapy
|
D063367 |
[Treatment technique in a virtual environment which allows the participant to experience a sense of presence in an immersive, computer-generated, three-dimensional, interactive environment that minimizes avoidance behavior and facilitates emotional involvement. (from Curr Psychiatry Rep (2010) 12:298)

Virtues
|
D028722 |
[Character traits that are considered to be morally praiseworthy. (Bioethics Thesaurus)
] |
|
Virulence
|
D014774 |
[The degree of pathogenicity within a group or species of microorganisms or viruses as indicated by case fatality rates and/or the ability of the organism to invade the tissues of the host. The pathogenic capacity of an organism is determined by its VIRULENCE FACTORS.
, The capacity of a microorganism to cause disease.
] |
|
Virulence Factors
|
D037521 |
[Those components of an organism that determine its capacity to cause disease but are not required for its viability per se. Two classes have been characterized: TOXINS, BIOLOGICAL and surface adhesion molecules that effect the ability of the microorganism to invade and colonize a host. (From Davis et al., Microbiology, 4th ed. p486)

|
Virulence Factors, Bordetella
|
D010566 |
[A set of BACTERIAL ADHESINS and TOXINS, BIOLOGICAL produced by BORDETELLA organisms that determine the pathogenesis of BORDETELLA INFECTIONS, such as WHOOPING COUGH. They include filamentous hemagglutinin; FIMBRIAE PROTEINS; pertactin; PERTUSSIS TOXIN; ADENYLATE CYCLASE TOXIN; dermonecrotic toxin; tracheal cytotoxin; Bordetella LIPOPOLYSACCHARIDES; and tracheal colonization factor.
] |
|
Virus Activation
|
D014775 |
[The mechanism by which latent viruses, such as genetically transmitted tumor viruses (PROVIRUSES) or PROPHAGES of lysogenic bacteria, are induced to replicate and then released as infectious viruses. It may be effected by various endogenous and exogenous stimuli, including B-cell LIPOPOLYSACCHARIDES, glucocorticoid hormones, halogenated pyrimidines, IONIZING RADIATION, ultraviolet light, and superinfecting viruses.

|
Virus Assembly
|
D019065 |
[The assembly of VIRAL STRUCTURAL PROTEINS and nucleic acid (VIRAL DNA or VIRAL RNA) to form a VIRUS PARTICLE.
] |
|
Virus Attachment
|
D053585 |
[The binding of VIRUS PARTICLES to VIRUS RECEPTORS on the host cell surface, facilitating VIRUS ENTRY into the cell.
] |
|
Virus Cultivation
|
D014776 |
[Process of growing viruses in live animals, plants, or cultured cells.
] |
|
Virus Diseases
|
D014777 |
[A general term for diseases caused by viruses.
] |
|
Virus Inactivation
|
D038301 |
[Inactivation of viruses by non-immune related techniques. They include extremes of pH, HEAT treatment, ultraviolet radiation, IONIZING RADIATION; DESICCATION; ANTISEPTICS; DISINFECTANTS; organic solvents, and DETERGENTS.
] |
|
Virus Integration
|
D016662 |
[Insertion of viral DNA into host-cell DNA. This includes integration of phage DNA into bacterial DNA; (LYSOGENY); to form a PROPHAGE or integration of retroviral DNA into cellular DNA to form a PROVIRUS.
] |
|
Virus Internalization
|
D053586 |
[The entering of cells by viruses following VIRUS ATTACHMENT. This is achieved by ENDOCYTOSIS, by translocation of the whole virus across the cell membrane, by direct MEMBRANE FUSION of the viral membrane with the CELL MEMBRANE, or by fusion of the membrane of infected cells with the membrane of non-infected cells causing SYNCYTIA to be formed.
] |
|
Virus Latency
|
D017735 |
[The ability of a pathogenic virus to lie dormant within a cell (LATENT INFECTION). In eukaryotes, subsequent activation and viral replication is thought to be caused by extracellular stimulation of cellular transcription factors. Latency in bacteriophage is maintained by the expression of virally encoded repressors.

Virus Physiological Phenomena
|
D018406 |
[Biological properties, processes, and activities of VIRUSES, including the interactions with the cells they infect.
