Furthermore, Murdoch and Lloyd provide evidence in the model of acute allergen-induced response that the gdT cell-dependent normalization of lung function and resolution of inflammation was dependent on the production of IL-17 [16] . These data provide evidence that IL-17A,F and IL-22 besides their inflammatory role have a negative regulatory function in allergic lung inflammation. On a mechanistic level, IL-17A elicits dual effects and reportedly promotes expression of proinflammatory (hemopoietic, CXC-chemokines, acute phase) factors [54, 55] , whereas it inhibits the production of mononuclear cell recruiting molecules like TNF-induced VCAM-1 and CC-chemokine RANTES [35] . IL-22 attenuates IL-25 production by lung epithelial cells and inhibits antigen-induced eosinophilic airway inflammation ./cache/cord-023950-nv0pbbu2.txt ./txt/cord-023950-nv0pbbu2.txt
