Research Abstract	本特定領域研究では、高次複雑系免疫システムの情報伝達制御機構の解明と、その異常による免疫疾患の発症機構を明らかにするために以下の研究項目を設定している。 A01:抗原非特異的分子による情報伝達制御 A02:抗原認識のシグナル変換機構 A03:免疫システム構築の情報伝達制御本総括班の目的は、1)上記の研究項目それぞれの年次ごとの研究評価を行い、計画立案に対する助言や計画に従って成果が蓄積されているか否かを厳密にチェックする、2)各々の研究項目の研究者が密な連携をもって、相補的に、また相互活性化しながら、研究を推進するように、公開シンポジウムの開催、研究資材の交換、共通な研究支援体制を確立する、3)情報公開を積極的に推進するなど、時機をえた柔軟な活動を行うことである。平成14年度は、7月9日に第一回総括班会議を、平成15年2月20日に第二回総括班会議を開催し、本特定領域研究の研究評価並びに研究計画に対する検討を行った。第一回班会議においては、平成14年度の方針を決めた。第二回班会議においては、本特定領域研究の研究評価をおこない、おおむね順調に計画が遂行されていることが確認された。ニュースレターNo.6(平成14年6月)、No.7(平成15年1月)を発刊した。情報の公開を促進する目的でホームページを開設し、内容の更新を随時行った。さらに、平成15年2月に、理学研究所・免疫アレルギー総合科学センターとの共同で、国際シンポジウムを開催した。海外から23名、特定領域研究班員を中心に、国内から24名の講演者によるシンポジウムを行った。海外からの40名を含めて、合計434名の参加のもとに、2月20日〜23日の4日間、熱心な発表、討論、情報交換を行った。このシンポジウム期間中に、本特定領域研究によっておこなわれた研究成果が、海外の研究成果と比較して、勝るとも劣らないことが確認できた。又、今後の免疫学研究の方向性が確認できた。
