Transient bilateral anterior uveitis occurs in EAE induced by myelin basic protein (MBP),12 whereas panuveitis occurs in EAE induced with S100B.13 MBP is also used to induce EAU.14 These experimental data imply some commonality in the precipitants of MS and uveitis that is further supported by evidence of autoreactive T cells from patients with MS displaying proliferative responses to retinal arrestin.15 This evidence concerns the gene S100B and myeloid sarcoma.
