Researchers theorize that asthma may be due to either inappropriate mast cell activation or that the mast cells are hypersecretory.[ref][ref] One study sums up that mast cells release preformed mediators including chymase, tryptase, and histamine and de novo synthesized mediators such as PGD2, LTC4, and LTE4 in addition of cytokines mainly TGF1, TSLP, IL-33, IL-4, and IL-13 participate in the pathogenesis of asthma.[ref] Related article : Asthma: understanding the genetics and underlying causes Osteoarthritis: Mast cells as a causative factor Osteoarthritis, the most common form of arthritis, is caused by inflammation and degeneration of the joint tissue
Therefore, even though a homeostatic axis whereby meningeal IL-17A release could signal in the cortex through Il17ra was previously proposed 47 , it is tempting to speculate that in AD, IL-1 derived from the brain parenchyma, could also signal back to the meninges, creating a feedback loop that sustains meningeal pT H 17 cells
