Inverse correlation between MPST expression and the expression of different molecules with pro-inflammatory properties (including pro-inflammatory cytokines, CD40L, CD69, IL2RA, CCR7) is consistent with the anti-inflammatory function of H2S. Furthermore, we have previously shown a reduced HMOX1 expression in the PBMCs of multiple sclerosis patients [15]. This evidence concerns the gene CCR7 and multiple sclerosis.
