NIH researchers have have described a novel autoinflammatory disorder called "Lyn kinase-associated vasculopathy and liver fibrosis" (LAVLI), based on a mutation in the LYN gene (that encodes the Lyn kinase protein). They discovered that increased Lyn kinase activity promotes systemic inflammation, by altering microvascular permeability and neutrophil recruitment, while at the same time promoting hepatic fibrosis.
