What is HIV Aidis?
What is HIV? HIV (human immunodeficiency virus) is a virus that attacks the body’s immune system. If HIV is not treated, it can lead to AIDS (acquired immunodeficiency syndrome). There is currently no effective cure. Once people get HIV, they have it for life.
Is Huv a virus?
HIV (human immunodeficiency virus) is a virus that damages the cells in your immune system and weakens your ability to fight everyday infections and disease.
Is HIV a Lent virus?
Lentiviruses include HIV-1 and HIV-2, SIV, caprine arthritis encephalitis virus, and visna virus. They encode several additional proteins, which vary among members of the genus. Lentiviruses are capable of infecting nondividing cells, and are named for the characteristically slow onset of the associated disease.
Can an undetectable person test negative?
The bottom line is that if you’re living with HIV and have an undetectable viral load, you will still test positive for HIV if you get tested. But, this is expected, and doesn’t mean that your treatment is not working or that you aren’t undetectable.
What does rev protein do?
Rev is a transactivating protein that is essential to the regulation of HIV-1 (and other lentiviral) protein expression. A nuclear localization signal is encoded in the rev gene, which allows the Rev protein to be localized to the nucleus, where it is involved in the export of unspliced and incompletely spliced mRNAs.
What are Gag and pol genes?
Gag is a polyprotein and is an acronym for Group Antigens (ag). Pol is the reverse transcriptase. Env in the envelope protein. The group antigens form the viral core structure, RNA genome binding proteins, and are the major proteins comprising the nucleoprotein core particle.
What is Rev lentivirus?
All lentiviruses encode a regulatory protein Rev that is essential for post-transcriptional transport of the unspliced and incompletely spliced viral mRNAs from nuclei to cytoplasm. The Rev protein acts via binding to an RNA structural element known as the Rev responsive element (RRE).
What does Pol gene mean?
Pol (DNA polymerase) refers to a gene in retroviruses, or the protein produced by that gene.
What are pol proteins?
Pol is the reverse transcriptase. Env in the envelope protein. The group antigens form the viral core structure, RNA genome binding proteins, and are the major proteins comprising the nucleoprotein core particle.
What does the pol gene encode?
The major read-through product is derived from the pol gene which encodes the reverse transcriptase (RT) and an integrase (IN) which is involved in provirus integration. The envelope gene encodes the surface glycoprotein (SU) – transmembrane (TM) polyprotein.
How is lentivirus transmitted?
Transmitted from person to person through direct exposure to infected body fluids (blood, semen) sexual contact, sharing unclean needles etc.; transplacental transfer can occur.
