I found this article that I found quite fascinating...a bit of background, though, many of you know that I think that MECFS is some sort of combination of high intracellular calcium levels which results in malfunctioning mitochondria and then some sort of impaired "clean up" (autophagy) process. The end result is a bunch of dud mitos and then we get inflammatory cytokines on top of it all in response to the cellular debris. And then the whole immune system goes off the rails and infections etc run rampant.
So imagine my surprise to discover that the active form of Vit D, calcitriol, is really much more of an immunomodulatory hormone than it is a vitamin. It can modulate cytokines and lowers intracellular calcium!

From the article:
Cytokine production is known to depend on intracellular calcium ([Ca++]i) [16,17]; moreover, it has also been shown that IL-2 production by T cells is stimulated by a rise in intracellular calcium [18]. Massry and Fadda described that leukocytes of CRF patients and those treated with hemodialysis have elevated basal levels of [Ca++]i, reduced adenosine 5′-triphosphate (ATP) content and impaired phagocytosis [19].
These derangements were related to secondary hyperparathyroidism. These authors also postulated that chronic elevation in [Ca++]i in T cells could interfere with the magnitude of the rise in [Ca++]i in response to stimulation of T cells, thus impairing the production of IL-2.
Since [Ca++]i seems pivotal in regulating cytokines secretion by monocytes from normal subjects and uremic patients, the present study was undertaken in order to establish a direct relationship between in vitro data and clinical effects.
