IL-2, IL-4, TNF-α, and IFN-γ levels in peripheral blood were significantly increased among the clinical responders (<i>p</i> < 0.05) while IL-6 and IL-10 were elevated among those with progressive disease (<i>p</i> < 0.05).
Our aims were to assess whether interleukin 6 (IL-6) promoter polymorphisms are associated with chronic hepatitis C virus (HCV) infection and to clarify the role of IL-6 haplotypes in facilitating progressive disease.
Plasma CD73, IL6, and VEGFD were identified as prognostic markers for progressive disease, and IL6 was associated with worse PFS confirming similar observations made in patients treated with other anti-angiogenic agents.
These data demonstrate that astrocyte-derived IL-6 is a key mediator of progressive disease and support IL-6 blockade as a viable intervention strategy to combat progressive MS.
