This study aimed to characterise the frequency of T regulatory cells (Tregs), dendritic cells (DCs) as well as sub-populations of T cells bearing regulatory properties like CD4+GITR+, CD4+CD62L+, CD3+TCRγδ+ along with the concentrations of IL-10, TGFβ, IL-6 in 66 patients with MM. This evidence concerns the gene IL6 and Miyoshi myopathy.
