• We comment on work by Schinkelshoek et al "H1N1 hemagglutinin-specific HLA-DQ6 restricted CD4+ T cells can be readily detected in narcolepsy type 1 patients and healthy controls. " in J. Neuroimmunology • These authors found no evidence of mimicry between flu hemagglutinin (HA) and Hypocretin (HCRT) • Referring to a paper by Luo et al. Proc. Natl. Acad. Sci. 115(52): E12323-E12332, 2018, we report that by sequencing 100 times more cells we do in fact find evidence for cross reacting TCR sequences, suggesting mimicry. [ABSTRACT FROM AUTHOR]
