Abstract: The invention provides a novel mouse IL-17F/IL-17A, and further provides uses of such mouse IL-17F/IL-17A in the characterization of the IL-17F/IL-17A heterodimer. The present invention is also related to polynucleotides and polypeptides of the IL-17F/IL-17A signaling pathway, and targeting of the IL-17F/IL-17A signaling pathway in methods of treating IL-17F/IL-17A-associated disorders. The invention thus provides methods of using isolated IL-17F/IL-17A heterodimer, e.g., in a mouse model of airway inflammation, and specific or selective IL-17F/IL-17A modulators (e.g., signaling agonists or signaling antagonists (e.g., specific or selective antagonistic antibodies, specific or selective antagonistic small molecules, etc.)). The invention also provides methods of screening for compounds capable of modulating IL-17F/IL-17A biological activity, e.g., IL-17F/IL-17A signaling antagonists (e.g.
