Immune System
This category is for questions about how our bodies identify and fight off disease, infection or pathogens through specialized cells, tissues and organs. The system that does this is called the immune system. It produces antibodies which recognize intruders and neutralizes potentially pathogenic organisms or substances.

How does active and passive immunity function?
Both passive and active immunity have role in the elimination of bacteria and naturalization of toxins. Extracellular bacteria G+ and G- induce inflammation and production of toxins. Hence, active immunity responses by production of antibodies and passive immunity via phagocytes and complement activation, cytotoxic production by macrophages.
The temperature response is helpful in fighting pathogens because?
bacteria that cause human diseases do not grow well at high temperatures
Where are Normal lymphocyte populations are maintained through lymphopoiesis?
bone marrow and lymphatic tissues
NO..Cameron Lane is alive, healthy and happy and still doing the occasional clip here and there..his most recent "Broke College Boys"..however Porn Actress
Cameron Bay does have aids..just because they have the same first name does not make them the same person..for the twits that still don't get it Cameron Lane is male..and Cameron Bay is female..Cameron Bay also went by Cameron Lane..still not the same person..Cameron is of Asian descent..has jet black hair, and dark eyes, he keeps his hair short..is slender and has a crazy little beauty mark under his left eye..

What cell in immune system gets rid of debris?
that depends what debris . a debris could mean "uremia" which can be filtered by the kidneys . or it could mean "antigen" that can be fought off by antibodies through the immune system or just basic germs and bacteria that can be thrown to the lymphatic system. the term "debris" seems to be very vague
What effect does gadolinium have on immune function?
Morgellons Disease seems to have the same exact reaction as gadolinium . The link is uncanny People with dental work and are suffering from unexplained illnesses. Gadolinium has many dental links , People that have unsolved medical problems could have a toxic load of gadolinium. Immune function seems to be everything plus, Skin Hair Eyes organs the great mimic like many diseases. I know it doesn't answer your question but put more questions on the table In our Blogg group I mentioned that MRIs caused alot of the same illnesses as morgellons and came up with the link.
How do the two major defense strategies of the immune system differ?
one likes men and the other doesnt
Are there vampires who are immune to garlic?
Immune is the wrong word. There are vampires that are unaffected by garlic, as it has no special meaning to vampires in general. Count Dracula had a strong adverse reaction to the stuff and from his fame the stereotype has become applied to all vampires. If you are being molested by a vampire do not count on garlic to save you.
Is there anything wrong men painting their toenails?
Yes! Many men wear nail polish on their toenails. It is gaining popularity, though some do not show it in public yet. That is changing as the newer darker colors are becoming popular because they look good on both men and women. Check out Suzi's Beauty Blog on the OPI web site. Select "for men" and find the blog posted for June 9. Here is a professional in the beauty industry promoting the use of nail polish on men's toes, and she even suggests a number of colors that do not exclusively look feminine. She also talks about the need for many men to get a professional pedicure, and if you look at many men's feet, it's not hard to imagine why she brings this up. Many women don't like the gender stereotypes forced upon them, why should men adhere to the stereotypes forced on them? What's good for the goose, is good for the gander afteralls! :-) Men were the first to wear markup, high-heels, stockings, skirts; why should we stop now, just because some people think they are "gay". The vast majority of gay men, wear VERY manly clothing! Most men who "cross-dress" are straight! Boxes are simply that, boxes that OTHER people force on us; why should we accept them?
We need vaccines to protect us from infectious diseases and to trigger the immune system to respond with production of antibodies made for that specific pathogen. See the related questions for more details of how this works.
Blood that is tested for HIV is tested for presence of antibodies to the virus not the virus itself?
true
The functions of antibodies is to?
Function of antibodies is to neutralizes the antigens that enters.
What is the normal white blood cell count?
Normal WBC starts at somewhere between 4.1 and 4.5 and goes up to 10 or 11.
Pan antibodies are manufactured and sold to allow the detection of certain proteins in samples. They are used by biochemists in the testing for various hormones.
The response to stimulous is that it's not a word. GIGO.
Is oral route of administration safer?
Yes the oral route for drug administration is the safest route.
Antibodies (also known as immunoglobulins,abbreviated Ig) are gamma globulin proteins that are found in blood or other bodily fluids of vertebrates, and are used by the immune system to identify and neutralize foreign objects, such as bacteria and viruses. They are typically made of basic structural units-each with two large heavy chains and two small light chains-to form, for example, monomers with one unit, dimers with two units or pentamers with five units. Antibodies are produced by a kind of white blood cell called a plasma cell. There are several different types of antibody heavy chains, and several different kinds of antibodies, which are grouped into different isotypes based on which heavy chain they possess. Five different antibody isotypes are known in mammals, which perform different roles, and help direct the appropriate immune response for each different type of foreign object they encounter.
Though the general structure of all antibodies is very similar, a small region at the tip of the protein is extremely variable, allowing millions of antibodies with slightly different tip structures, or antigen binding sites, to exist. This region is known as the hypervariable region. Each of these variants can bind to a different target, known as an antigen. This huge diversity of antibodies allows the immune system to recognize an equally wide diversity of antigens. The unique part of the antigen recognized by an antibody is called an epitope. These epitopes bind with their antibody in a highly specific interaction, called induced fit, that allows antibodies to identify and bind only their unique antigen in the midst of the millions of different molecules that make up an organism. Recognition of an antigen by an antibody tags it for attack by other parts of the immune system. Antibodies can also neutralize targets directly by, for example, binding to a part of a pathogen that it needs to cause an infection.
The large and diverse population of antibodies is generated by random combinations of a set of gene segments that encode different antigen binding sites (or paratopes), followed by random mutations in this area of the antibody gene, which create further diversity. Antibody genes also re-organize in a process called class switching that changes the base of the heavy chain to another, creating a different isotype of the antibody that retains the antigen specific variable region. This allows a single antibody to be used by several different parts of the immune system. Production of antibodies is the main function of the humoral immune system.
What is the first line of defense against infection?
Your skin,sweat,mucus,and tears is the first line of defense of your immune system. it is the original protector from bacteria and viruses
