their patients. It is then their job to analyze this information. They then have to put all of the pieces of information that they find together to create a diagnosis for their patient. Immunology can be a very dangerous field for a person with no antibodies. Immunologists often times deal with microbiological cultures and possibly biohazard cultures as well. Very often times are an immunologist associated with a Allergist because they deal with the reaction and rejection of the body to foreign micro

against antigens. Leukocytes are more focused and are a second line of defence against specific antigens. T-lymphocytes (T-cells) attack anything carrying disease in the body. B-lymphocytes (B-cells) are tuned to a particular antigen‚ and produce antibodies to destroy them. Immunosuppression is a reduction in the effectiveness of the immune system and can be caused by stress. Arnetz et al (1991) - Reduced lymphocyte activity in farm labourers was associated with periods of stressful unemployment

tissues. This network aids in the removal of waste and unwanted products from the body. The lymphatic system’s most important function is to transport white blood cells that fight infection called lymph though the body. These white blood cells contain antibodies which are built to detect‚ destroy and build immunity towards pathogens and infections that enter the body. The lymphatic system consists of lymphatic vessels‚ lymphatic organs and lymph. Lymphatic Vessels Lymphatic vessels are tubes with thick

rare is called anaphylactic shock. 9. What is it called when the body produces antibodies and sensitized T cells that attack and damage its own tissues? An autoimmune disorder is when the body in essence attacks itself. 10. Tissue grafts taken from unrelated persons are called allografts. 11. Small proteins that diffuse to nearby cells and bind to their membrane receptors are called interferons. 12. Antibodies are also referred to as immunoglobulins or IGS and constitute the gamma globulin

April 11‚ 2012 The Complement System The complement system is a nonspecific defense mechanism activated in response to invading organisms. This system gets its name from the fact that it complements the action of antibodies. It is the primary mechanism activated by antibodies to kill foreign cells by forming membrane attack complexes. In addition to directly lysing the invading organisms it also reinforces the general inflammatory tactics. It can be activated in two ways: 1. A nonspecific

Introduction: Over the past three decades we have witnessed a tremendous amount of activity in the area of biosensors. Biosensors are small devices employing biochemical molecular recognition properties as the basis for a selective analysis. The major processes involved in any biosensor system are analyte recognition‚ signal transduction‚ and readout. Due to their specificity‚ speed‚ portability‚ and low cost‚ biosensors offer exciting opportunities for numerous decentralized clinical applications

helper T cells or even a memory T cell; the latter of which is imperative in making vaccines effective. Yet‚ a small lymphocyte may also be a B lymphocyte cell‚ which find themselves as the war factories during a battle against disease; producing antibodies that can lock onto foreign cells like jigsaw pieces‚ disabling them in action. Yet‚ only once activated by a helper T cell will they become plasma cells‚
