AS Psychology Unit 2: Stress-illness and The Immune System Notes The immune system refers to the mechanism in the body that provides a defence against infections‚ e.g. bacteria‚ viruses‚ parasites and toxins.

this happens‚ it is known as an infection which in turn make people ill. Our body uses its immune system to fight of the infection that has began spreading in the body. Vaccines are used to help our immune system develop an immunity by imitating the infection. This means that there is a small amount of the bacteria or virus introduced to the body but it does not make the person ill. This causes the immune system to create t-lymphocyttes and b-lymphocytes‚ white blood cells that attack cells that have

bring these two types of molecules together so that they can effectively activate even more T cells (“up to 20% of all T cells”) in a non-specific manner due to the superantigen binding to the Variable B region of T cells. Cytokines‚ which are immune system proteins which are secreted for the purpose of carrying signals amongst cells‚ are released as a result of this increased activation of T cells and may even induce toxic shock. This Toxic Shock Syndrome is due to Staphlyococcus aureus‚ characterized
