Mechanisms of pathology

preview:First lines of defence • Barriers-skin, mucosal surfaces (epithelial cells) • Prevent entry of pathogens • Mechanical • Chemical • Microbiological • We have got a multi layered defense. • the first lines of defense are always ready for action these are barriers, these are our skin, these are mucosal surfaces, and these prevent the entry of pathogens. • We have barriers that are mechanical, chemical and microbiological. • For mechanical barriers you can se...

• Adaptive immunity is the third line of defence. • It happens after the physical barriers such as tears, skin mucous and stomach acid. • This is followed by innate immunity which is the immune system that is present from birth, this includes soluble mediators such as complement and cytokines in the blood. And also includes a number of cell types that it can immediately recognise and attack pathogens after they have infected our body. • Adaptive immunity • Requires different types ...

preview:• also known as immunoglobulins (Ig) • Ab are the targeted weapons of the adaptive immune system • clear extracellular pathogens and neutralise toxins • produced by activated, effector B lymphocytes (plasma cells) • circulate in plasma and lymph and are found at mucosal surfaces • specific – bind only a single antigen (Ag) • the antibody repertoire is very large – 109-1016 unique molecules • Antibodies are able to clear extracellular pathogens and neutralize t...
