Pío del Río Hortega (1882 – 1945) was a Spanish neuroscientist who discovered microglia. ==Biography== Río Hortega was born in Portillo, Valladolid on 5 May in 1882.〔 He studied locally and qualified to practice medicine in 1905. He obtained his doctorate at the University of Madrid by researching the pathology of brain tumours. In 1913 he was funded to study research histology in France and Germany but the outbreak of war between them forced him to return to Spain.〔 He worked with the histologist Santiago Ramón y Cajal and briefly with Wilder Penfield. Ramón y Cajal discovered neurons, Penfield helped explain oligodendroglia. whilst Rio Hortega discovered microglia.〔(【引用サイトリンク】url=http://www.britannica.com/EBchecked/topic/1725960/Pio-del-Rio-Hortega )〕 which are the cells that protect the brain from infection. He managed to identify microglia between 1919 and 1921 by staining the cells with silver carbonate.〔 His method of staining also led to the discovery of oligodendroglia in 1921, which both he and Penfield are now credited with.〔 However it was Rio Hortega who named the cells.〔(【引用サイトリンク】url=http://tigger.uic.edu/~abouller/history.html )〕 His discoveries in 1920 created issues with Ramón y Cajal, who led the lab, as he had earlier won the Nobel prize. By 1931 del Río Hortega was leading Spain's cancer institute, but he left the country when the civil war broke out in 1936.〔 War spreading across Europe found him in Paris at the Pitié-Salpêtrière Hospital in Paris before he went to the University of Oxford to work with the British neurosurgeon Hugh Cairns.〔(【引用サイトリンク】url=http://translate.google.co.uk/translate?hl=en&sl=es&u=http://www.historiadelamedicina.org/hortega.html&prev=/search%3Fq%3DPio%2Bdel%2BRio-Hortega%26hl%3Den%26client%3Dfirefox-a%26hs%3Dmh4%26tbo%3Dd%26rls%3Dorg.mozilla:en-US:official&sa=X&ei=0cvQUJuBOsiA0AWCx4HQCg&ved=0CHkQ7gEwBw )〕 The bombing of Britain by Germany in World War II drove him on to Argentina. His escape was funded by the Spanish Cultural Institute, who continued to support hm as he created his own laboratory in 1942. Río Hortega died in Buenos Aires on 1 June in 1945 from a malignant neoplasm.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pío del Río Hortega」の詳細全文を読む スポンサード リンク
