Given the genetic association with the HLA-DQB1 * 06:02 allele and environmental links with the 2009 influenza pandemic, many lines of evidence point towards an immune mechanism, notably autoimmunity, underlying the disease pathophysiology. Autoreactive T cells are found in the blood of NT1 patients, and mouse models demonstrate their migratory capacity and contribution in the selective destruction of hypocretin-producing neurons. However, direct evidence for their role in human NT1 pathophysiology remains elusive. In complementing these findings, hypothesis-generating approaches-including multiparametric immune profiling, transcriptomic sequencing and large-scale proteomic of blood and cerebrospinal fluid-have uncovered promising new avenues into the immune system&#8217;s involvement in NT1. In this review, we explore the mechanisms driving NT1 pathogenesis, emphasizing both hypothesis-driven and hypothesis-generating approaches, and discuss potential future directions that could pave the way for targeted immunotherapies.<\/p>\n<p>PMID:<a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/40373365\/?utm_source=WordPress&amp;utm_medium=rss&amp;utm_content=9009458&amp;ff=20250516114841&amp;v=2.18.0.post9+e462414\">40373365<\/a> | DOI:<a href=\"https:\/\/doi.org\/10.1016\/j.smim.2025.101962\">10.1016\/j.smim.2025.101962<\/a><\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Semin Immunol. 2025 May 14;78:101962. doi: 10.1016\/j.smim.2025.101962.
