Targeting Autophagy in Dendritic Cells as a Mechanism to Limit Immunopathogenesis in Herpetic Stromal Keratitis

In a recent mBio article, Y. Jiang, X. Yin, P. M. Stuart, and D. A. Lieb [mBio 6(6):e01426-15, 2015, doi:10.1128/mBio.01426-15] presented an elegant set of experiments that utilized a transgenic, knockout strain of mice whose dendritic cells (DCs) are incapable of undergoing autophagy, to dissect out the aspects of the chronic inflammatory response following viral infection of corneal epithelial cells. The authors' results provide a potential proof of concept that the DC autophagy pathway may be a valid target for therapeutic drug design in certain inflammatory pathologies.
