Brown Norway Rat

 

命名:BN/Crl

類型:近交系

毛色:非刺鼠型棕色Non-agouti brown

MHC 單體型: RT1n

來源:1930 年,Dr. Helen Dean King將捕捉的野生大鼠帶回實驗室,藉由傳統繁育方式(pen-bred)成功馴化與繁育在 Wistar 研究所;1958 年,Silvers 和 Billingham 從 Dr. King 和 Dr. Paul Myron Aptekman 共同飼養的野生鼠族群中選取一株棕色突變體,開始進行同胞兄妹交配與並同時篩選出免疫系統中組織相容性複合物基因型相同的個體;1976 年,Charles River(CRL)從荷蘭放射生物學研究正式引入;2026 年,樂斯科公司自CRL引入該品系核心種源進行繁殖培育。

應用:遺傳圖譜分析、呼吸道發炎、視網膜變性、免疫功能障礙、老化、器官移植研究。

與其他常見的白化大鼠不同(如 Sprague Dawley 或 Wistar),BN大鼠擁有有色眼睛(pigmented eyes),這使其眼球構造與人類視網膜更為相似,因此常年被作為視網膜退化、青光眼、糖尿病視網膜病變及葡萄膜炎等眼科醫學研究的標準模型。

在呼吸系統研究中,其關鍵優勢是其在過敏模型中表現出一致的反應,並具有獨特的肺部免疫學和病理生理學特徵。近年亦有文獻開始應用於食物過敏與致敏性風險評估。

由於其MHC Haplotype 為RT1n,經常與 Lewis大鼠(RT1l) 配對作為移植排斥研究,可作為急性細胞介導排斥反應ACR、急性抗體介導排斥反應AAMR、慢性排斥與免疫耐受之研究,用於機制探討與藥物開發之模式。

BN大鼠亦常用於雄性生殖老化的模型,隨著年齡增長,會出現血清睪固酮水平降低、睪丸間質細胞類固醇生成能力下降、支持細胞功能和數量減少、生精小管體積和精子含量顯著降低以及生殖細胞凋亡加速等現象。
