Abstract
We used NBUVB lamps (10 KJ/m2) to irradiate both wild type (WT) and 1α-hydroxylase knockout mice (CYP27B1 KO) that were then induced to develop EAE. There was a complete elimination of EAE development by NBUVB in the KO mice. On the other hand, the NBUVB treatment of WT mice reduced but did not eliminate the severity or incidence of EAE. This suggests that the presence of 1,25-dihydroxyvitamin D3 actually counteracts the suppressive effect of NBUVB. In support of this concept, cytokines (IFN-γ, IL-10) and chemokine (CCL-5) mRNA in spinal cord were reduced in wild type or eliminated in the KO mice by the NBUVB. Cytokine mRNA levels in the spinal cord correlated with clinical scores in both WT and KO mice.
