IgE is a type of anibody and elevated levels of IgE means that one suffers from hypersensitivity. one may have atopic dermatis, rhinitis, or allergic Asthma. Also, high IgE level most of time collerates with high Th2 level.

What type of blood cell is responsible for immunity?

Specific immunity is also known as adaptive immunity or acquired immunity active or passive. There are two types of specific immune responses; humoral and cell mediated. Humoral immunity is mediated by B Lymphocytes that produce antibodies; forms of B lymphocytes are IgG, IgM, IgA, IgE. They primarily attach bacterial invaders Cellular immunity is mediated by T Lymphocytes and combat intracellular infections (such as viruses), monitor cellular disruptions like tumors or foreign tissues, and fight fungal infections.


How can B cell mature into plasma cell?

The surface immunoglotulin that serves as the B-Cell antigen receptor (BCR) has two roles in B-cell activation. First, like the antigen receptor on T cells, it transmits signals directly to the cell's interior when it binds antigen. Second, the B-Cell antigen receptor delivers the antigen to intracellular sites where it is degraded and returned to the B-cell surface as peptides bound to MHC class II molecules.


How does a fever help your body when you are sick?

Your immune system recognises a foreign body in your circulation and through an Ige response liberates specific antibodies created only to fight that specific virus into your bloodstream. These antibodies then find and encapsulate the virus. Once they have done that they then start to digetst it. Once digersted the virus is inactivated, The antibodies then " return to the garage" To await any further invasion by similar invaders. Thus immunity is aquired.


What are two main components of an immune response?

The human immune system is a very complex system build up of numerous functional parts.To understand how the immune system works it is essential to know the functional parts and their role in the system therefore we will list you the functional parts and what role they play in the immune system. What triggers them to react and to fulfill their role in defending our body from various malicious intruders that can harm us.White blood cells:White blood cells are a very important part of your immune system. They are actually a large collection of different cells that work together to destroy bacteria and viruses. Here are the different types, names and classifications of white blood cells working inside your body right now:• Leukocytes• Lymphocyte• Monocytes• Granulocytes• B-cells• Plasma cells• T-cells• Helper T-cells• Killer T-cells• Suppressor T-cells• Natural killer cells• Neutrophils• Eosinophils• Basophils• Phagocytes• MacrophagesAll white blood cells are known as Leukocytes. They act like independent, living single-cell organisms that can move like amoeba and capture things on their own by engulfing them. Most of them are created in the bone marrow and start out as stem cells.There are three types of Leukocytes: • Granulocytes which comprise 50 to 60 percent of all leukocytes. They are further divided into three types of Granulocytes: Neutrophils, Eosinophils and Basophils. Granulocytes get their name because they contain granules. These granules contain different chemicals depending on the type of cell.• Monocytes which comprise approximately 7 percent of all leukocytes. Monocytes eventually become macrophages.• Lymphocytes which comprise 30 to 40 percent of all leukocytes. Lymphocytes are the white cells that are the key operatives of the immune system. There are two kinds - B lymphocytes (B cells) and T lymphocytes (T cells). Those that mature in bone marrow are called B cells and those that mature in the thymus are called T cells.Most of the organs of the immune system are concerned with the growth, development, and deployment of lymphocytes. These organs are called lymphoid organs.Lymphocytes travel through the blood searching for foreign cells. B cells use antibodies to target bacteria. T cells actually do the fighting.B cells work by using tiny antibodies. There are thousands of different B cells in the blood at any time, each armed with antibodies against a particular germ. But there are only a few of each until there is contact with any particular germ. Then, B cells multiply dramatically very quickly and release large amounts of the right antibodies.The process works like this: when a germ bumps into a B cell, the B cell multiplies, forming versions of itself called "plasma" cells. Plasma cells make antibodies to attack the germ. The antibodies lock on to the target germ to make it easy for phagocytes to eat. Some of the B cells continue multiplying after the germ has been destroyed, so that if the germ returns, there are antibodies ready for it.T cells work a little differently. Because many germs, such as viruses or parasites, hide inside cells, it is the job of the T cells to identify and destroy these cells. There are two kind of T cells: "killer" cells and "helper" cells. Helper cells are the ones that identify the invaded cells and send out the alarm. Killers are the ones that move in and destroy them.This happens because an invaded cell gives itself away with abnormal proteins on its surface. When helper cells encounter abnormal proteins, the send out chemicals called lymphokines that tell killer cells to multiply. The killer cells lock on to the abnormal cell and destroy it. And, like B cells, some killer cells stay around, ready to attack any more abnormal cells they meet.Antibodies:Antibodies (also referred to as immunoglobulins and gammaglobulins) are are Y-shaped proteins that respond to specific bacteria, viruses or toxins, called antigens. They are produced by white blood cells.Antibodies can bind to toxins, disabling their chemical actions or signal that an invader needs to be removed.These antibodies are divided into five classes. Their names are generally abbreviated. For instance, Immunoglobulin A is abbreviated IgA. Here are all of the abbreviations: IgA, IgD, IgE, IgG, i IgM.Bone marrow:©1994 Terese WinslowBone marrow produces new red and white blood cells. Red blood cells are fully formed in the marrow and then enter the bloodstream. Most white blood cells mature elsewhere, however, in factories located inside the long bones of our bodies. The marrow produces all blood cells from stem cells. They are called "stem cells" because they are precursors to different cell types. They can branch off and change into specific types of white blood cells, as needed.Complement system:If germs get through the body's physical and chemical barriers into the bloodstream, a mixture of liquid proteins called complement is activated and attacks them. The complement system includes a series of proteins. While there are millions of different antibodies in your blood stream, each sensitive to a specific antigen, there are only a handful of proteins in the complement system. They float freely in your blood. Complements are manufactured in the liver. The complement proteins are activated by and work with (complement) the antibodies. They cause lysing (bursting) of cells and signal to phagocytes that a cell needs to be removed.Interferon:Interferon is another type of protein produced by most cells in the body. One job of interferon is to let cells signal one another. When a cell detects interferon from other cells, it produces proteins that help prevent viral replication in the cell and also stimulates killer cells. Interferon is the main anti-viral defense of the body. In fact Interferon was named that because it was the first compound scientists identified that "Interfered" with the virus' ability to attach to cells and cause disease. An increase in the body's production of Interferon means an increase in the body's natural defense against any viral infection.Hormones:There are several hormones generated by the immune system. These hormones are generally known as lymphokines. Some hormones in the body suppress the immune system. These are the steroids and corticosteroids (components of adrenaline).Lymph nodes are basically filters that trap germs and other foreign bodies. The nodes have armies of lymphocytes to deal with the germs. Lymphocytes are a type of white blood cell, which neutralizes or destroys germs. The lymph nodes can become swollen when fighting an infection.Lymphoid organs include the bone marrow and the thymus, as well as lymph nodes, spleen, tonsils and adenoids, the appendix, and clumps of lymphoid tissue in the small intestine known as Peyer's patches.There are about 2 to 4 pints of lymph fluid in the average body.Spleen:The spleen filters the blood looking for foreign cells. The spleen is also looking for old red blood cells that need replacement. It is an organ about the size of a fist in the upper left of the abdomen. The spleen contains two main types of tissue: red tissue that disposes of worn-out blood cells, and white tissue that contains lymphoid tissue. Different part of the the spleen specialize in different kinds of immune cells. When microorganisms get carried by the blood into the red tissue, they become trapped by the immune cells known as macrophages.Thymus:The thymus is located in your chest, between your breast bone and your heart. It is responsible for producing T-cells and is important for T cell maturation.
