What does it mean if something is a retrovirus?

What does it mean if something is a retrovirus?

RNA to DNA: It means that the RNA of the virus gets "reverse transcribed" into dna so it can the be inserted into the human dna. This is the opposite of what usually happens (dna gets transcribed into rna). It's called a "retrovirus" because the transcription is backwards. ...Read more

Is it true that rhinovirus is a retrovirus?

Is it true that rhinovirus is a retrovirus?

No: It is a picornavirus. There are some similarities (it's genome is made of rna) but it is not a retrovirus (like hiv). It is a cause of the common cold, and it typically not life threatening. ...Read more

Why is a retrovirus harder to treat than other viruses?

Why is a retrovirus harder to treat than other viruses?

They can hide in DNA: Retroviruses have the ability to insert themselves into the dna, effectively "hiding" themselves from the immune system. Also, they rapidly mutate which can prevent the immune system from attacking them. ...Read more

Is the influenza a retrovirus?

Is the influenza a retrovirus?

No, but its still...: ...Deadly. Influenza is still a leading killer, inspite of the existence of a vaccine. It is not part of the family of viruses known as retroviruses, which tend to incorporate themselves into the genome of the host cell. Get your flu-shopt every year and wash your hands regularly during the flu-season. ...Read more

Please help Baby 2 mths old blood test positive for something "retrovirus" can't get hold of doctor for more info until Monday what could it be?

Don't ask yet: It was a mistake to give you this partial information, so it is likely that the information itself is mistaken. Don't pursue this until you are able to get an accurate answer from the physician; if it is serious, he/she will probably schedule a face-to-face meeting. ...Read more

Why are retroviruses such as HIV notoriously difficult to treat?

Why are retroviruses such as HIV notoriously difficult to treat?

Mutating&Evolving: It was difficult to treat in eightees when the virus was discovered&there was no drugs to treat but over the years many new drugs and combination of drugs have been discovered&it has become easier to treat Yes it is difficult to treat because retro virus is constantly mutating,changing and basically evolving and that's the reason the virus evades the drugsThats why it is difficult to make Vaccine ...Read more

How do retroviruses such as HIV differ from other types of viruses?

How do retroviruses such as HIV differ from other types of viruses?

Rev transcriptase: "retro-" means backwards and the virus carries RNA which is translated backwards to dna by their own reverse transcriptase; the dna is then integrated into the host's genome. The "endogenous retroviruses" can even be passed from generation by infection the sperms / eggs. ...Read more

Please tell me if there are any other retroviruses besides hiv-aids?

Please tell me if there are any other retroviruses besides hiv-aids?

Retroviruses: Yes, there are many. Some that might be familiar to you include HTLV (human t cell lymphotropic virus), Feline Leukemia virus, Feline immunodeficiency virus. There are many. ...Read more

Why are retroviruses the only group of RNA viruses that can cause cancer?

They don't penetrate: DNA viruses don't have the capability of entering the cell membrane. As such when one sees DaNA on tumor membrane it is from mutated mitochondrial DNA. The RNA viruses penetrate the cell and elaborate reverese transcriptase to allow transfection of the nuclear DNA. This enzyme only occurs with the retroviruses. ...Read more

Why are human endogenous retroviruses (herv's) "activated" in some people, but not in others, when exposed to exogenous viruses? Genetic mutations?

Why are human endogenous retroviruses (herv's) "activated" in some people, but not in others, when exposed to exogenous viruses?  Genetic mutations?

HERV's evolutionary: Endogenous retroviruses have made us evolve. They make up 8% of our dna genome. These aren't of the same class as HIV (lentivirus) or htlv (deltaretrovirus). Few are active & only w/growth & infection. Co-infection w/hiv can turn on herv replication wh/allows our immune system ability recognize & kill HIV viruses w/herv presenting-hiv infected cells leading to new therapies for HIV (vaccines!). ...Read more

Is it true that olive leaf extract kill viruses and retroviruses like HIV and htlv?

Doesn't matter: I don't know, but it really doesn't matter. There are lots of things that kill hiv, such as soap and water. Killing HIV isn't the answer. The answer is to stop HIV from replicating and to be able to eliminate latent infection, which olive leaf extract won't do. ...Read more
