Abstract
Corneal infection with herpes simplex virus (HSV) leads to the recruitment of immune cells to the eye itself, the trigeminal ganglion and the brainstem. In addition, some resident cells in these target tissues are infected by HSV, activated during the inflammatory response or both. Chemokine signaling is an important component of the regulatory circuit governing the host immune response to virus infection. This review discusses chemokine responses in relation to HSV infection of the cornea emphasizing the role of CXCR3 chemokine signaling by the IFN-? inducible ligands MIG, IP10 and I-TAC and includes discussion of their potential role in immunopathology in the nervous system.
