The association runs through cathelicidin and the EGFR.

Vitamin D deficiency: the invisible accomplice of metabolic endotoxemia?

The aetiology of obesity is multi-factorial. Recent research has
identified a novel association between endotoxaemia (circulating
lipopolysaccharide in the systemic circulation) and low-grade
inflammation in the adipose organ, which may contribute to obesity. The
mechanisms for the low-grade elevation of circulating lipopolysaccharide
in obesity are poorly understood. Vitamin D has been increasingly
recognised for its pleiotropic actions beyond maintenance of
musculoskeletal health. The parathyroid-vitamin D axis is altered in
obesity. Circulating vitamin D levels are lower in obese individuals.
The regulatory role of vitamin D in the immune system and colonic mucosa
may explain the under-appreciated contribution of vitamin D deficiency
in the obese to the pathogenesis of endotoxaemia and adipose
inflammation. We propose a hypothetical model linking metabolic
endotoxaemia with vitamin D deficiency in obesity. A therapeutic
approach involving the use of probiotics and vitamin D metabolites in
the obese is described.
