Un importante análisis de datos genéticos ha relacionado 127 ubicaciones génicas con la enfermedad de Alzheimer, incluidas 48 identificadas anteriormente. Los investigadores también señalaron varios genes como dianas farmacológicas prometedoras y destacaron cambios en las células inmunitarias y nerviosas.

El estudio examinó información del genoma de casi 110,000 personas diagnosticadas con alzhéimer y otras 74,000 que tenían un progenitor con la enfermedad. Se comparó esta información con datos de 2.6 millones de personas sin la patología. Este esfuerzo permitió identificar 127 ubicaciones génicas asociadas, 48 de las cuales son nuevos hallazgos.

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.

Japan scientists identify clusters of protein believed to trigger Alzheimer’s disease

Japanese researchers have identified a new seed of the amyloid beta protein. The discovery could lead to early-stage therapy for the neurodegenerative disease.

USC researchers identify compounds targeting Alzheimer’s brain inflammation
