Which cells alert the body that a virus has entered the bloodstream?
The body has two immune response processes to combat viruses.The first is called Innate Immunity and works within a few hours of an infection. With this reaction, inflammation occurs which is triggered by Toll-like receptors (TLR). These TLRs are pattern recognition receptors. They activate the Interferon (IFN) regulatory pathway, and in turn, the infected cell secretes IFN-beta. IFN-beta warns neighboring cells of the infection, and triggers the PAX/STAT pathway which leads to the production of antiviral agents and chemokines to increase the flow of macrophages and Natural Killer (NK) cells to the site of the infection.After a few days, the second immune response, adaptive immunity kicks in. Here dendritic cells (antigen-presenting cells) are infected and carry the virus to the lymph organs. In the lymph organs the virus triggers the proliferation of B and T cells (lymphocytes that are each specific for a particular antigen) which produce antibodies to combat the infection.
What infection results when the bloodstream carries the bacteria or virus and their toxins to all parts of the body?
A general infection
What is viremic dissemination?
Viremic dissemination refers to the spread of a virus through the bloodstream to different parts of the body. This process allows the virus to infect multiple tissues and organs, leading to systemic infection.
What is the normal progression for Japanese encephalitis?
an infected mosquito sucks that person's blood. Once in the body, the virus travels to various glands where it multiplies. The virus can then enter the bloodstream. Ultimately, the virus settles in the brain
What alert the body that a virus has enter a blood stream?
There are certain cells in the blood whose surfaces have holes all over that exactly fit every kind of bacteria and virus that you are immune to. The germs fall into those holes, are captured, and cannot cause infection. Now, along comes a bunch of a certain virus that you are not immune to - they do not fit any holes in those certain cells. The certain cells try to grab the new viruses, but can't, so they release a tiny bit of chemical that travels in the bloodstream to the brain, causing the brain to release a tiny bit of chemical into the bloodstream that starts up the disease-fighting mechanisms of your body.
Will there be a treatment to cure you if you had HIV?
Once you are diagnosed with HIV, or when HIV enters the bloodstream, there is no known cure in which it eliminates the HIV virus from the bloodstream. Usually when you are diagnosed the doctor will then take a blood test to see how much of the virus is in your body per milimeter of blood and also how many CD4 cells (tcells) are also in your bloodstream. If the tests come back that there are more than 200 tcells per millimeter of blood, the Doctor may not put you on HIV medications since your body can still fight infection on it's own. If your tcells are 200 or below, your body can no longer fight off infection and he or she will then start you on HIV medications. Depending on what strain of the virus you have, the Doctor can start you on numerous different kinds of medication combinations. Don't get confused that the HIV medications DO NOT cure HIV from your bloodstream, all it does is stop HIV from attaching to your tcells, and stops the virus from duplicating and keeping the virus undetectable. This way the virus is no longer attacking your immune system, but the virus is hiding mainly in the lymphnodes, and if you were to stop taking the antiretrovirus medications, the virus would come out of remission and start attacking the body again.
How does dengue enter the human body?
Dengue virus enters the human body primarily through the bite of an infected Aedes mosquito, particularly Aedes aegypti and Aedes albopictus. When the mosquito bites, it injects saliva containing the virus into the bloodstream. The virus then targets immune cells, allowing it to replicate and spread throughout the body, leading to the symptoms associated with dengue fever.
In osmosis Jones what does the killer virus thorax take that changes franks body temperature?
In "Osmosis Jones," the killer virus Thorax injects a toxin into Frank's bloodstream, which causes his body temperature to rise. This rise in temperature is part of the virus's strategy to create an environment conducive to its survival and replication, leading to a fever. This reaction triggers the immune response, setting the stage for the battle between the body's defenses and the invading virus.
Explain how the HIV affect the body Specifically which white blood cell?
When HIV virus entered in the body of mainly first to be aware with that particular body so that soon enough they go and attack the white blood cells which known as CD4 which are responsible for the protection of the body against diseases and infection so when HIV virus data When HIV virus entered in the body of mainly first to be aware with that particular body so that soon enough they go and attack the white blood cells which known as CD4 which are responsible for the protection of the body against diseases and infection so when HIV virus attack them at last the body remains with few CD4 that course welcoming of other different diseases and infection
Will infectious agents always affect the same organ or tissue they have entered?
No, infectious agents don't always affect the same organ or tissue they have entered. For instance, chickenpox virus (varicella) enters the body through the mucous membranes of the upper respiratory tract, but spreads throughout the body.
How would you describe the medical condition polio?
The virus enters the body through the mouth and travels from the intestine to the lymphatic system into the bloodstream and eventually invades the central nervous system and the brain.
Do al drugs enter the bloodstream?
The bloodstream is the roads, the railways, and the airports of the body. Everything that goes from one part of the body to another enters the bloodstream at some point.
