Previous research reports have supported the hypothesis that there are low levels of serum TRIB2 autoantibodies in HLA-DQB1*06:02-positive young narcolepsy patients with cataplexy, which they linked to influenza pandemic vaccination and A/H1N1 antibodies in 2009 [74,75,76,77,78,79,80]. Here, TRIB2 is linked to Cataplexy.
