What is it about?

The metabolic enzyme glutamate dehydrogenase, present in helminth viable larval cyst, mediates a novel PGE2-IL-10 axis of regulatory T cell induction, potentially controlling brain inflammation. PGE2 and IL-10 are induced by glutamate dehydrogenase from tolerogenic-like monocytes and microglia and act on G protein-coupled receptors EP2 and EP4 and IL-10 receptor. The absence of glutamate dehydrogenase in degenerated larval cyst products promotes inflammatory non-phagocytic microglia expressing the pro-epileptic factor TGF-ß.

Why is it important?

Harnessing the novel PGE2 -IL-10 axis and targeting TGF-ß signaling may offer an important therapeutic strategy in inflammatory epilepsy and NCC.
