美國費城兒童醫院Mariko L. Bennett對環境和起源對駐留於大腦的巨噬細胞的影響及其治療意義進行了綜述。該文章12月2號在線發表在國際學術期刊《自然—神經科學》上。
小膠質細胞是大腦和脊髓的組織內巨噬細胞。它們對中樞神經系統發育、正常功能和退化都很重要。與傳統單核細胞衍生的巨噬細胞不同,小膠質細胞來源於胚胎卵黃囊造血祖細胞,並在整個生命過程中自我更新。小膠質細胞在組織駐留巨噬細胞中也具有獨特的遺傳特徵。 最近的研究確定了大腦內環境和發育史對小膠質細胞轉錄組的影響。在這篇綜述中,研究人員介紹了這些文獻,並討論了起源對小膠質細胞功能的潛在影響,特別是使用骨髓或幹細胞來源的細胞治療神經系統疾病的現有和未來療法。

Title: The influence of environment and origin on brain resident macrophages and implications for therapy

Abstract: Microglia are the tissue-resident macrophages of the brain and spinal cord. They are critical players in the development, normal function, and decline of the CNS. Unlike traditional monocyte-derived macrophages, microglia originate from primitive hematopoiesis in the embryonic yolk sac and self-renew throughout life. Microglia also have a unique genetic signature among tissue resident macrophages. Recent studies identify the contributions of both brain environment and developmental history to the transcriptomic identity of microglia. Here we review this emerging literature and discuss the potential implications of origin on microglial function, with particular focus on existing and future therapies using bone-marrow- or stem-cell-derived cells for the treatment of neurological diseases.
