    Collapse Overview 
    Collapse Summary
    Dr. Almeida’s primary focus is elucidating the molecular mechanisms of frontotemporal dementia (FTD), amyotrophic lateral sclerosis (ALS) and Alzheimer’s disease (AD). Her main strategy employs patient-derived, induced pluripotent stem cell (iPSC) lines to generate disease-relevant neuronal cells.
    Collapse overview
    My primary research focus is on understanding the molecular mechanisms of frontotemporal dementia (FTD), amyotrophic lateral sclerosis (ALS) and Alzheimer disease (AD). Our strategy involves the use of patient derived cellular models. To date we have generated induced pluripotent stem cell (iPSC) lines from FTD and ALS/FTD patients carrying mutations in progranulin, C9ORF72, TDP-43 and MAPT, as well as lines from healthy controls. I have differentiated these iPSCs into post-mitotic cortical and motor neurons and applied a variety of approaches to uncover underlying molecular and cellular defects. This approach allows the interrogation of patient-derived neurons in the appropriate, differentiated context, leading to a better understanding of how ALS/FTD mutations impact cellular physiology, resulting in their pathogenic consequences. We are also using a gene editing approach to create CHMP2B mutant iPSCs that can be differentiated into a cellular model for the study of AD cellular pathogenesis. I am particularly interested in exploring and testing potential therapeutic interventions to halt or slow the progression of these and related diseases.

    PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
