免疫研究部 TOP      



免疫研究部では、免疫細胞や炎症が神経障害を引き起こす仕組みを解明し、難治性神経疾患に 対する画期的な治療法を開発するため、日夜研究を続けています。特に中枢神経系の自己免疫 疾患である多発性硬化症(MS)や視神経脊髄炎(NMO)の基礎研究では、NATURE、NATURE IMMUOL、PNASなどに論文を多数発表しています。レベルの高い基礎研究の成果を臨床応用に発展させる 実力を持ち、「神経免疫」の領域では日本を代表する研究拠点になっています。

最近では「医療スーパー特区」のプロジェクト研究を走らせ、独自に開発した新規治療薬の実用化に 力を入れている他、自己免疫や神経免疫の基礎研究も推進しています。


神経系の炎症・免疫応答の研究は神経難病の新しい治療法の開発に欠かせません。当研究部は海外の一流の研究室との交流も深め、新しい方法論を取り入れながら着実に歩み続けています。多発性硬化症の発症にNK細胞やNKT細胞が関係していることや、腸内細菌と自己免疫疾患、視神経脊髄炎とIL-6など、当研究室から世界に向けて発信して来た情報は数えきれません。この領域に関心のある大学院生、医師、研究者などの皆さんは、是非門を叩いてください。

当研究部はこの10年で数百編の論文を発表していますが、その中でコアになる代表的な
