The present invention relates to methods of modulating the level of inducible nitric oxide synthase (iNOS) in a cell which comprises administering to the cell a compound which modulates binding of SPRY domain-containing SOCS box protein (SSB) to iNOS, and/or a compound which modulates SSB activity in the cell. Further provided are methods of treating or preventing disease in a subject by modulating the level of iNOS in a cell, as well as compounds which modulate binding of SSB to iNOS and compounds which modulate SSB activity.
