Research Interests

Ana’s research aims to dissect the mechanisms underlying glia response and interplay with neurons in neurodegenerative diseases, namely ALS and AD. She is involved in the isolation of microvesicles and exosomes from different models (microglia, astrocyte primary cultures, motor neuron, microglia cell lines and iPSCs-derived neurons and astrocytes), and in their characterization (NTA, microRNA profiling). She is also interested in evaluating inflammatory mediators in monocultures, co-cultures and brain/ spinal cord from transgenic mice.
