Uma grande análise de dados genéticos relacionou 127 localizações genéticas à doença de Alzheimer, incluindo 48 que não haviam sido identificadas anteriormente. Os pesquisadores também apontaram diversos genes como alvos promissores para medicamentos e destacaram alterações nas células imunes e nervosas.

O estudo examinou informações do genoma de quase 110.000 pessoas diagnosticadas com Alzheimer e outras 74.000 que tinham um dos pais com a condição. Esses dados foram comparados com informações de 2,6 milhões de pessoas sem a doença. Esse esforço identificou 127 localizações genéticas associadas, sendo 48 delas novas descobertas.

Study finds blood-cancer-linked mutations in brain immune cells tied to Alzheimer’s pathology

Researchers at Boston Children’s Hospital report that mutations commonly associated with clonal blood-cell expansion and some blood cancers were enriched in microglia-like immune cells in Alzheimer’s brains and were also detectable in matched blood samples. The Cell study proposes that age- or injury-related weakening of the blood-brain barrier could allow mutated blood immune cells to enter the brain, potentially amplifying inflammation and contributing to neurodegeneration.
