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.

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.

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.

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.

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.

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?

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.

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

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.

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.

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!).

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.

How is ED caused by Peyronie's disease?

How is ED caused by Peyronie's disease?

Here are...: Thus far, what we've known is as follows: The "scar formation" - Peyronie's plaque - interferes the proper shut-off of venous flow to maintain and sustain the high blood pressure inside corpora cavernosa as penile arteries inflow for erection. Besides, at age goes, many affected men may have some dysfunction of local vessels and nerves for regulating erection so ED ensues. More? Ask Doc timely.

How do salmonella species cause disease (s)?

Ingested: Salmonella spp. Are contracted through food, water, and contaminated hands. Once in the intestine they can cause diarrhea or spread to the blood and possibly other organs.

Which disorders cause a 7 years old boy (having good grades) to sit alone in school despite he's social in family? P.S:he visits an orthophonist weekly

Which disorders cause a 7 years old boy (having good grades) to sit alone in school despite he's social in family? P.S:he visits an orthophonist weekly

Shyness: Some children are shyer than others, but some kids can get stressed at school. Talk to him about how he is doing. Is he anxious or stressed? Does he enjoy school? How are his grades? If you are concerned that he is depressed or having school problems, talk with his doctor or a therapist.

How does Crohn's disease cause welling of the leg (s)?

How does Crohn's disease cause welling of the leg (s)?

Few ways.: Crohn's is an inflammatory disease that releases inflammtory mediators into the blood stream. There may be some small component of edema from that. Secondly it is also associated with an arthritis that can cause local joint edema and an increase in distal lymphatic pressure. Thirdly there may be protein / malabsorption losses which can increase edema.

Can athlete’s foot cause any other, more serious, diseases?

Can athlete’s foot cause any other, more serious, diseases?

Other infections: Athletes foot, a fungal infection, can cause cracks and fissures in the skin, which can serve as an entry point for a bacterial skin infection leading to cellulitis. Additionally, the fungal infection from athletes foot can also lead to a fungal infection of the toenails.
