WIKIMEDIA, JOHN VANDERPOELLate last year, Elizabeth Mellins and Emmanuel Mignot of Stanford University and their colleagues found a possible explanation for why one out of 15,000 children who received the Pandemrix H1N1 vaccine developed narcolepsy—that the children’s own T cells were targeting hypocretin, a hormone that helps keep people awake. The study, which was published in Science Translational Medicine, received significant media attention, including from The Scientist, and was touted by one researcher as “one of the biggest things to happen in the narcolepsy field for some time.”
But upon failing to reproduce the findings, the authors have retracted their study. Specifically, the test the researchers used to identify the T cells of interest, the Enzyme-Linked ImmunoSpot (ELISpot), is no longer yielding the same results. According to a statement from Mignot, e-mailed to reporter Ed Yong who covered both the initial publication in Nature and the retraction on his National Geographic blog Not Exactly Rocket Science, “After many attempts in several settings and verification of all reagents, we decided to withdraw the manuscript. . . . We have already moved forward with other interesting findings on the narcolepsy/H1N1 association.”
“This may indeed be considered as a blow to the field,” Gert Lammers, president of the European Narcolepsy Network, told Not Exactly Rocket Science, ...
