摘　　要：Everyone knows that an infection can make you feel sick.Although we perceive infection-induced changes in metabolism as a pathology,they are a part of a carefully regulated process that depends on tissue-specific interactions between the immune system and organs involved in the regulation of systemic homeostasis.Immune-mediated changes in homeostatic parameters lead to altered production and uptake of nutrients in circulation,which modifies the metabolic rate of key organs.This is what we experience as being sick.The purpose of sickness metabolism is to generate a metabolic environment in which the body is optimally able to fight infection while denying vital nutrients for the replication of pathogens.Sickness metabolism depends on tissue-specific immune cells,which mediate responses tailored to the nature and magnitude of the threat.As an infection increases in severity,so do the number and type of immune cells involved and the level to which organs are affected,which dictates the degree to which we feel sick.Interestingly,many alterations associated with metabolic disease appear to overlap with immune-mediated changes observed following infection.Targeting processes involving tissue-specific interactions between activated immune cells and metabolic organs therefore holds great potential for treating both people with severe infection and those with metabolic disease.In this review,we will discuss how the immune system communicates in situ with organs involved in the regulation of homeostasis and how this communication is impacted by infection.
