Immune System

No, they are entirely two different things. What might stimulate a receptor could be an antigen.

The endocrine system.

The immune system needs to destroy the pathogens. Other wise the pathogens will multiply in the body of host. The pathogens will multiply by geometrical proportion. With in very short time the pathogens will occupy the whole body. You can no longer survive in that case.

An interferon designated as beta-1b enhances the activity of T-cells, while simultaneously reducing the production cytokines that operate in the inflammatory response to infection and injury

The process is not fully understood, but some of the more current thoughts are that the flu prefers and thrives better in the humidity of colder weather (drier absolute humidity) compared to humidity in other seasons. It is thought that it might be only the humidity level differences that link viral flu and cold infections to the fall and winter seasons, but, as has often been cited, perhaps there is also a component of the closer proximity of people to each other indoors in the cold weather which allows for easier direct transmission of the viruses. Scientific studies have ruled out a role of weather temperature differences. It is proven that you don't get colds from being cold.

Other reasons are sometimes given, for example, one thought is that it is the lowered amount of available sunlight in these seasons and shorter length of time periods that people are outside in the sun that result in lower Vitamin D (the "sunshine vitamin") levels. Deficiency of Vitamin D can impact the immune system negatively, but there is not consensus among the medical community on how much impact this actually may or may not have on infection rates.

Another factor that gets discussed is that there may be an effect from lowered amounts of sunlight, especially ultraviolet sunlight, available in those seasons which helps to de-activate the viruses.

You are correct that it is not the cold temperature that gives us colds, but rather the microorganisms that move from person to person during the "cold and flu season" that make us sick with the flu or a common cold.

Pathogens in dental care refer to harmful microorganisms that can cause infections or diseases in the mouth. Common dental pathogens include bacteria like Streptococcus mutans (causes cavities) and Porphyromonas gingivalis (causes gum disease). Proper oral hygiene practices, such as brushing and flossing regularly, can help prevent the growth of these pathogens.

An antigen is any substance that causes your immune system to produce antibodies against it. An antigen may be a foreign substance from the environment. If you get a vaccine for rubella, the antibody formed will not act against mumps (another virus).

Since the bacteria has already invaded your body, the second stage of defense is required. The lymphocytes will engulf the bacteria and digest it using lysosomes. When the bacteria is gone, fragments of the bacteria are left behind by the lymphocyte to allow some T-cells to identify the bacteria's antigen.

No. They are microorganisms that cause disease.

A cytotoxic T-cell is a form of lymphocyte that is the "killer" T-cell. This cell engulfs damaged or viral/bacterial cells to stop them from infecting the blood.

Genes provide the instructions for building antibodies through a process called gene expression. Specialized immune cells called B cells undergo a complex process of gene rearrangement and mutation to generate a diverse array of antibodies that can recognize specific pathogens. This genetic information is then used by the cell to produce the corresponding antibody protein.

The answer is: D) lymph node.

If you have an an inflammatory form of arthritis like for example RA it is the immune system that is attacking your joints and you need to treat it by suppressing the immune system to a degree. you would be wise to check with your doctor what treatments are best for you to self administer in any case.

The cause of vasculitis diseases is usually not known. is understood that immune system abnormality leading to inflammation is the most common feature. The characteristics and symptoms of the disease depend on what particular organs are affected.

Vasculitis include diseases succh as Kawasaki disease, Behcet's disease, polyarteritis nodosa, Wegener's granulomatosis, cryoglobulinemia, Takayasu's arteritis, Churg-Strauss syndrome, giant cell arteritis (temporal arteritis), and Henoch-Schönlein purpura.

A. Suppressor T cells decrease their activity in response to decreasing antigenic stimulus to help prevent unnecessary immune responses. B. Suppressor T cells are not the most thoroughly understood T cells; their function and role in the immune system continue to be studied and better understood.

There are quite a few ways to become immune to smallpox. One way is that you can be infected with the disease Cowpox. Which is not deadly in anyway but is a disease nobody wants to have. Another way is, you can infect your self with smallpox and give yourself a mild case of it. It is proven that once you had smallpox and you survived you never get it again, by infecting yourself mildly you can become immune to it.

Correction mild case of smallpox is cowpox if u become infected with cowpox u become immune to smallpox and cowpox for the rest of your life it is like a vaccination but instead of being shot with it u actually become sick but once you get over it your completely immune to it or any other more serious case of the illness.

Tattoos, like piercings, are foreign to the natural state of the human body. It was not meant to have any foreign bodies injected. When the body senses "foreign matter" it activates its immune system and the cells used in fighting diseases, viruses and colds is kicked into action. When the foreign bodies are not ejected/fixed or eliminated from the human body the state of the "fighting" immune cells become dulled to the presence of the piercing or the tatoo.

In essence the body comes to accept the foreign matter and in a sense become complacent. Now when a virus comes along, such as H1N1 or H5N1, these fighter cells have become complacent and therefore do not have the same efficacy as they once did, therefore lowering the bodies immune system. Voila...the virus/cold is in and the body can't fight it.

Try to keep your body free of foreign matter which includes the following:

1. Nitrates (found in processed meats)

2. Alcohol and Tobacco

3. Pharmaceuticals (seek the natural way in all cases possible)

4. All fast foods

5. Piercings and Tattoos

Your immune system will be boosted and stronger with the following aids:

1. Food Grade Diatomaceous Earth (I use it daily and it cleans the body of toxins)

I bought in B.C. Canada from I think it was called Nature's Gaia Company.

2. Aloe Vera juice (found at most local health food stores)

3. Coconut oil/milk

4. Fresh mint and ginger root

The white blood cells called T-Cells after being created in the bone marrow migrate to the thymus gland and must stay there for period of time to mature before they can properly function.

It really depends on what drug has been taken. Some (like most antidepressants) need only observation and careful monitoring, others will need to be treated with a charcoal solution that is drank. Paracetamol and I should imagine... most other drugs is usually treated with an anti serum given via IV. Stomach pumping isnt used as often anymore.

An immune response is based on the ability to distinguish molecules that are part of the body ("self") from those that are not ("nonself," or foreign). Such molecules that can elicit an immune response are called antigens.
