CCL24 and fibromyalgia: The full cytokine profile and the topic of vitamin D in fibromyalgia was not discussed although a study finds vitamin D might play a role in myofibroblast attenuation or de-differentiation [292], and a meta-analysis suggests fibromyalgia is associated with a unique cytokine profile: TNF-α, IL-6, IL-8, IL-10 and eotaxin/CCL24 [293], all of those found to be implicated in myofibroblast cellular signaling [294–298].
