Resumo de Recurso
Barriers to infection
Skin
Epidermis
Mechanical barrier of dead epithelial cells
Waterproof and frequently shed
Sweat galnds
Sweat includes fatty acids to inhibit growth of some bacteria
Physical breach of the epidermis will lead to an inflammation response
GI tract
Low pH and thick mucus layer in the stomach
Mucus and immune surveillance in the small intestine
Proteases, lipases and bile released into the dueodenum
Competition by commensal micro-flora
Immune surveillance in the small intestine
Crypt secretions
Payers patches
Bile is released into the duodenum
Produced by hepatocytes
Alkaline bile neutralises stomach acid
Bile salts act as bacteriocides
Stomach
Low pH and tick mucus layer in the stomach
Micro-flora
Produce antimicrobial agents to suppress pathogens
Important in defence and can influence development
Enzymes
Lysozyme breaks down peptidoglycan
Blood clotting
Coagulation system overlaps with the innate immune system
Increase vascular permeability
Act as chemotactic agents for phagocytic cells
Directly antimicrobial e.g. beta-lysine
2 activation pathways
Contact activation pathway (intrinsic pathway)
Tissue factor pathway (extrinsic pathway)
There is inhibition of excessive clotting
Complement pathway
