Background & aimsIn our previous study, a Seesaw model was proposed for the fluctuation of crucial anti-(IL-10) and pro-inflammatory (Il-6 & IL-17A) cytokines through vitamin D 3 . In this paper, however, it is intended to extend the mentioned model by assessing the expression mRNA levels of IL-27 and TGF-β1 as well as the changes of plasma levels of IL-27, TGF-β1, IL-17A, IL-10, and IL-6 after treatment by vitamin D 3 .
MethodVenous blood samples were drawn from Healthy Participants (HP, n = 25) and First-Degree Relative Participants (FDRP, n = 25) as control groups and Multiple Sclerosis Participants (MSP, n = 25) before and after eight weeks of supplementation with 50000 IU vitamin D 3 . The mRNA expression and plasma concentrations were gauged by using Real-Time PCR and ELISA assay, respectively.
