1a) In the normal immune system‚ describe two features of self-tolerance as applied to T cells and B cells (ie. central tolerance‚ peripheral tolerance‚ suppression‚ anergy‚ etc.). Central tolerance is the process which occurs in the primary lymphoid organs of the thymus for T cells and the bone marrow for B cells‚ where B and T cells which recognize and react to self-antigens are destroyed‚ through apoptosis (McCance & Huether‚ 2014). The process were a B or T cell reacts to self-antigen is called

Question to answer after watching the Interactive Physiology - The Immune System: Innate Host Defenses 1. Name the two major categories of innate (nonspecific) defenses: • Surface Barriers • Innate Internal Defenses 2. Surface barriers include the Intact skin and mucous membranes of the respiratory‚ gastrointestinal and genitourinary tracts. 3. List the three properties of skin that help it resist invasion: • Keratin: tough protein in skin cells‚ forms an abrasion- and water-resistant outermost

Outline and Evaluate Research into the Relationship between the Immune System and Stress Related Illness There is evidence to suggest acute stressors can cause suppression of the immune system and decrease immune cell functioning. The study by Kiecolt-Glaser et al. (1984) investigated whether the stress of taking exams caused a change in the amount of white blood cells in the blood. Kiecolt-Glaser studied 49 male and 26 female first year medical students at the Ohio State University College

research into the effects of stress on the immune system The immune system helps fight off attacks from ‘foreign invaders’‚ the immune system is a network of cells‚ tissues and organs that help fight off attacks from viruses‚ parasites and micro organisms that enter our bodies that can cause infections and other problems. The idea that all the cells in our bodies have codes ‘tattooed’ onto them that are unique to each of us help us understand what the immune system does clearer. Whenever micro organisms

Outline and evaluate the research into the effect of stress on the immune system During strenuous times‚ our body undergoes many physiological changes in order to aid our survival‚ and this is an inherited function (Canon’s ‘fight or flight’ theory). Stress in small doses‚ in fact is needed and useful to humans‚ however long term stress can take its toll on the body. The General Adaptation Syndrome (GAS) model was developed by Selye to explain the effects of exposure to stressor. The GAS model consists

(Grande & Mezebish‚ 2008). Skin grafting used to be very problematic because of the body’s negative immune response‚ but with advances in science and medicine‚ skin grafting techniques and acceptance have come a long way. The immune system functions to protect the body against actual or potential disease or illness. Anything not recognized a part of the body it protects‚ causes the immune system to initiates steps to attack the foreign invader. This is a significant problem in terms of skin grafting

The effects of catecholamines on the immune system in particularly the effects they have on T-helper lymphocytes The immune system is a vast and versatile collection of cells within the human body. These cells prevent the spread of infections‚ viruses and bacteria throughout the entire body and help in maintaining a healthy lifestyle. The immune system can be affected in many ways with a variety of substances up or down regulating its ability to function correctly. Catecholamines which are found

The role MHC class II plays on the immune system is that some of its genes code for proteins that will be expressed on the surface of the immune system cells. Peptides which are protein fragments outside the cells will allow these proteins to be attached to them‚ if these proteins are recognised by the immune system as foreign (such as viral and bacterial) the MHC will send a signal to the immune system to trigger an immune response against the invading bacteria or virus. The HLA class I and class
