Document Summary

Types of immune cells: neutrophils target bacteria; mechanism = phagocytosis, eosinophil"s target multicellular pathogens (helminthes); mechanism = reactive oxygen species (ros; enzymes for degrading dna and rna, monocytes i) macrophages target bacteria; mechanism = phagocytosis; ii) dendritic cells = antigen presenting cells, messengers between innate/adaptive immune systems, lymphocytes i) b cells target viruses and bacteria; mechanism = antibodies ii) cytoxic t cells target viral infected and tumorous cells by recognizing antigenic markers (antibodies, mhc); mechanism = apoptosis iii) helper t cells activate cytoxic t cells, adaptive regulation of b cell function, promote. Impairment during infection (sickness behaviour) (cid:224) treat as a disorder; force normal functions (cid:224) ultimately does not help body: lethargy (cid:224) increase physical exercise, inability to concentrate (cid:224) attention focusing drugs, social withdrawal (cid:224) increase social interaction, sleeping more (cid:224) limit sleep to 8 hours, eat less (protein) (cid:224) eat more (protein, sexual difficulties (cid:224) regular sexual activity (viagra)
