Answer: An antibody is a label that the immune system produces, which attaches itself to an antigen (which ideally is an invading micro-organism) and which then signals the macrophages to eat that antigen, thereby destroying it.
Answer: When germs get inside you, white blood cells in your blood start to make antibodies. These are special chemicals the find germs and then stick to them. This helps other white blood cells in your body find the germs and destroy them. When you are sick, your body makes more white blood cells to protect you.
Answer: The human immune system has two defenses against intracellular pathogens likemalaria. The initial defense is a population of cells called NK or Natural Killer cells which seek out cells lacking specific markers (MHC complexes, a major protein often downregulated in infected cells) and destroy them along with whatever is infecting them. They require no priming. The slower but more specific and effective defense is a type of T cell known as CD8+ cytotoxic T lymphocytes which provide the same function, they search for cells presenting pathogen antigens (in this case malaria antigens) on there surface, and destroy them along with the malaria. Macrophages also have limited intracellular pathogen destroying capabilities, and clean up the dead cells and malaria after the call has apoptosed (died).
This system is effective and is why there are capable vaccines against malaria. Sadly though, for those that are not vaccinated, its possibe that the initial immune response will not be sufficient and the malaria will multiply out of control of the immune system and a back up with quinine will be needed.
Answer: He was the first physician to use disinfection in a hospital setting. He used "carbolic acid" solution to disinfect medical apparatus in the operating room and strict hand-washing techniques to ensure midwives did not transfer infection from one patient to another.
Answer: Pathogens do not fight disease. In fact, pathogens are the foreign agents in the body that may cause disease. They are the agents that macrophages and other phagocytes will try to kill in the body.
Do proteins help fight disease?
NO they actually increase disease
This Answer Above is Completely Incorrect: Find help elsewhere.
Answer: Proteins can and do fight diseases upon by a process of producing a substance which is called interferon. This can be obtained by eating foods rich in vitamin C or taking vitamin C. Hope this was helpful.
Answer: An antibodyis a large Y-shaped protein used by the immune system to identify and neutralize foreign objects such as bacteria and viruses. The antibody recognizes a unique part of the foreign target, termed an antigen. Each tip of the "Y" of an antibody contains a paratope (a structure analogous to a lock) that is specific for one particular epitope (similarly analogous to a key) on an antigen, allowing these two structures to bind together with precision. Using this binding mechanism, an antibody can tag a microbe or an infected cell for attack by other parts of the immune system, or can neutralize its target directly (for example, by blocking a part of a microbe that is essential for its invasion and survival). The production of antibodies is the main function of the humoral immune system.
