human immunodeficiency virus & AIDS What does human immunodeficiency virus rack for? human immunodeficiency virusÂ is theÂ humanÂ immunodeficiency virus. some(prenominal) muckle get flu wish well symptoms after a few weeks of getting HIV on the dot others do non get any symptoms There ar medications that brook irksome down the destruction of the immune system, improve the wellness of people and reduce ability to transmit HIV untreated early HIV infection is also associated with many diseases including cardiovascular disease, kidney disease, liver disease, and cancer A blood test for HIV looks for these antibodies. If you have them in your blood, it mean that you have HIV infection. muckle who have the HIV antibodies argon called HIV-Positive. How many types are there?Â Two types of HIV, HIV-1 and HIV-2.Â They are retroviruses. An ribonucleic acid virus (a virus smooth not of deoxyribonucleic acid but of ribonucleic acid). Retroviruses have an enzyme called v olte-face transcriptase that gives them the unique property of transcribing RNA (their RNA) into DNA. The retroviral DNA can because integrate into the chromosomal DNA of the host cell to be expressed there. Outside of a human cell, HIV exists as roughly spherical particles (sometimes called virions). The originate of each particle is continue with lots of little spikes. HIV particles surround themselves with a pelage of fatty material cognize as theÂ viral windbagÂ (or membrane).
Projecting from this are round 72 little spikes, which are formed from the proteins gp120 and gp41. Just to a lower place the vir al envelope is a layer called theÂ matrix, w! hich is made from the protein p17. The viralÂ inwardnessÂ (or capsid) is usually bullet-shaped and is made from the protein p24. Inside the core are tercet enzymes required for HIV replication called reverse transcriptase, integrase and protease. to a pick held within the core is HIVs transmissible material, which consists of two identical strands ofÂ RNA. current of air Transcription and Integration Once inside the cell, the HIV enzyme reverse transcriptase converts the viral RNA into DNA, which is compatible with human genetic material.
