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 is permissive and non permissive cells?
Permissive cells are capable of supporting the replication of a virus, whereas non-permissive cells are unable to support virus replication. In permissive cells, the virus can enter, replicate, and exit to infect other cells. Non-permissive cells may lack the necessary factors or receptors for the virus to complete its replication cycle.
What virus attacks the cells in the immune system that produce antibodies?
HIV (Human Immunodeficiency Virus) attacks the T cells, which are a type of immune cell that plays a crucial role in coordinating the immune response, including the production of antibodies. By destroying these cells, HIV weakens the immune system's ability to fight infections effectively.
How do you B and T cells fight the virus?
B cells produce antibodies that can bind to the virus and neutralize it, while T cells can directly kill virus-infected cells. B cells also help activate T cells to coordinate a more effective immune response against the virus. Through these mechanisms, B and T cells work together to eliminate the virus from the body.
What are the cells called that police the body in blood and lymph to kill cancer cells and virus infected body cells?
The cells you are referring to are called natural killer (NK) cells. NK cells are a type of white blood cell that plays a crucial role in the immune system by identifying and eliminating cancerous cells and virus-infected cells in the body. They are part of the body's innate immune response.
What substance produced by virus infected cells diffuses to neighboring cells to help them fight a viral infection?
Interferons are substances produced by virus-infected cells that help neighboring cells fight viral infections. They trigger the immune response in nearby uninfected cells, stimulating them to produce antiviral proteins to combat the infection and prevent further spread of the virus.
What alert the body a virus has entered the bloodstream?
nerve cells
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.
How do killer cells work?
Killer t cells are activated by helper t cells. The Helper t cells are alerted by the macrophage that has engulfed the virus. It grows antigens to alert the helper t cells. The killer t cells are like white blood cells, there purpose is to fight pathogens.
Can a virus have cells?
No, a virus cannot have cells.
What two responses do helper T cells activate to fight viruses?
Helper T cells activate cytotoxic T cells to directly kill virus-infected cells and activate B cells to produce antibodies that can neutralize viruses. This dual response helps to eliminate the virus from the body efficiently.
WHAT IS THE RED ALERT VIRUS EMAIL?
The answer is internet security company
How does HIV affect white blood cells?
First of all, the virus enters the bloodstream, the body attacks it with white blood cells or T cells. The body produces more cells and very soon, outnumber the virus and go in for the kill. Suddenly, the virus fights back and shows that he is no one to mess with. After he destroys the defenses and goes further into the body. After the defenses are out, even simple diseases can pass through such as the common cold. You can even die from these simple diseases. All of these are the causes of HIV attacking your white blood cells.
Is a virus made up of a cell or cells?
No, a virus is not made up of cells. It is a small infectious agent that can only replicate inside the cells of living organisms.
AIDS is caused by what a virus that infects what?
AIDS is caused by a virus called HIV. HIV enters the bloodstream and directly attacks certain cells that are designed to protect us from infection. The cells involved are called CD4+ or T-helper cells. These cells play a major role in preventing germs from hurting us. When these cells die or are killed off, our bodies lose the ability to fight infections. This is ultimately what causes people to get sick and even die.
What is the first event that occurred when a virus infects the host cell?
The virus attaches to the host cells membrane.
Is there a cure for HIV when its in the bloodstream?
There is no cure for HIV at the moment, but there is a daily medication that stops it multiplying. You can have small traces of the virus in your bloodstream without any problem. It's only if the virus is allowed to multiply in your blood that it can cause problems.
A Virus Has No Outer Membrane Is it a cell?
Virus have no cells
