Subjects with CIS may convert to clinically established MS, however no biomarker may predict the individual risk.
Lymphocyte dopaminergic receptors (DR)- and adrenoceptors (AR)-operated pathways are dysregulated in MS and may predict the response to IFN-β.
We now show that lymphocyte expression of several DR and AR mRNAs are upregulated in CIS subjects.
DR D3, α2A-AR, and DR D5 mRNA after first neurologic event correlate with conversion to MS at 12 months, contributing to predict the risk of MS.
