Pesquisa

Nosso grupo investiga mecanismos que causam falhas de sinapse e perda de memória na doença de Alzheimer (DA). Nossas abordagens experimentais compreendem uma combinação de modelos moleculares, celulares e animais da DA, bem como estudos em coortes de pacientes. A motivação central de nosso trabalho vem da crença de que um conhecimento profundo dos mecanismos que causam a perda de funções cerebrais é necessário para o desenvolvimento de novas estratégias de prevenção ou tratamento da DA, levando a uma melhoria na qualidade de vida de milhões de indivíduos afetados pela doença em todo o mundo, além de suas famílias e cuidadores.

Palavras-chave: doença de Alzheimer, demência, memória, sinapse, mecanismos de estresse celular
