“…Inflammatory response components, such as those involved in the interleukin 1 (IL-1) system, have been suspected to play a role in FS [Gatti et al, 2002]. Recent reports indicate that certain SNPs in genes that encode other inflammation-related molecules, such as IL-6 [Shahrokhi et al, 2014], IL-6 receptor, prostaglandin E receptor 3, purinergic receptor P2X7, or TLR-4, may be involved in the pathogenesis of FS [Emsley et al, 2014].…”
