Human TH17 lymphocytes promote blood-brain barrier disruption and central nervous system inflammation


Kebir, Hania; Kreymborg, Katharina; Ifergan, Igal; Dodelet-Devillers, Aurore; Cayrol, Romain; Bernard, Monique; Giuliani, Fabrizio; Arbour, Nathalie; Becher, Burkhard; Prat, Alexandre (2007). Human TH17 lymphocytes promote blood-brain barrier disruption and central nervous system inflammation. Nature Medicine, 13(10):1173-1175.

Abstract

T(H)17 lymphocytes appear to be essential in the pathogenesis of numerous inflammatory diseases. We demonstrate here the expression of IL-17 and IL-22 receptors on blood-brain barrier endothelial cells (BBB-ECs) in multiple sclerosis lesions, and show that IL-17 and IL-22 disrupt BBB tight junctions in vitro and in vivo. Furthermore, T(H)17 lymphocytes transmigrate efficiently across BBB-ECs, highly express granzyme B, kill human neurons and promote central nervous system inflammation through CD4+ lymphocyte recruitment.
