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

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

Acquired immune deficiency syndrome‚ or AIDS‚ is a recently recognized disease. It is caused by infection with the human immunodeficiency virus (HIV)‚ which attacks selected cells in the IMMUNE SYSTEM and produces defects in function. These defects may not be apparent for years. They lead‚ however‚ to a severe suppression of the immune system ’s ability to resist harmful organisms. This leaves the body open to invasion by various infections‚ which are therefore called opportunistic diseases‚ and

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

In Daniel Gilbert’s essay‚ “Immune to Reality‚” he explores how each person’s psychological immune system plays a major role in allowing him or her to cope with traumatic situations that come up in daily life. The psychological immune system is the mind’s cognitive mechanisms that work subconsciously to make the existing state of affairs more bearable. It does this by allowing the brain to make excuses for negative events‚ which‚ in turn‚ help the troubled individual feel better. Gilbert’s conclusions
