Mast cells contribute to autoimmune diabetes by releasing interleukin-6 and failing to acquire a tolerogenic IL-10+ phenotype
2017
Mast cells (MCs) are innate immune cells that exert positive and negative immune modulatory functions capable to enhance or limit the intensity and/or duration of adaptive immune responses. Although MCs are crucial to regulate T cell immunity, their action in the pathogenesis of autoimmune diseases is still debated. Here we demonstrate that MCs play a crucial role in T1D pathogenesis so that their selective depletion in conditional MC knockout NOD mice protects them from the disease. MCs of diabetic NOD mice are overly inflammatory and secrete large amounts of IL-6 that favors differentiation of IL-17-secreting T cells at the site of autoimmunity. Moreover, while MCs of control mice acquire…
Phosphodiesterase10A: abundance and circadian regulation in the retina and photoreceptor of the rat.
2011
Phosphodiesterase10A (PDE10A) is a dual specific cyclic nucleotide phosphodiesterase that is specifically enriched in striatum and which has gained attention as a therapeutic target for psychiatric disorders. The present study shows that PDE10A is also highly expressed in retinal neurons including photoreceptors. The levels of PDE10A transcript and protein display daily rhythms which could be seen in preparations of the whole retina. Corresponding changes in PDE10A mRNA were seen in photoreceptors isolated using laser microdissection. This suggests that the expressional control of the photoreceptor Pde10a gene contributes to the observed cyclicity in the amount of retinal PDE10A. The daily …
