NEUROTROPHIC FACTORS & DRUG DISCOVERY
(@ NEUROSCIENCES AND PHARMACOLOGY)
Brain-derived neurotrophic factor (BDNF) is a key neurotrophin that supports neuronal survival, differentiation, and synaptic plasticity. It plays a central role in learning, memory, and overall brain function. Alterations in BDNF signaling have been consistently observed across a wide range of diseases, including neurodegenerative disorders, psychiatric illnesses, and neurodevelopmental diseases. Disruptions in its pathways are considered fundamental contributors to disease mechanisms of these pathological conditions. BDNF is also a critical molecule within the heart–brain axis, and maintaining its balance is essential for both neural and cardiovascular health.
The research group of Neurotrophic Factors & Drug Discovery is dedicated to advancing the understanding of BDNF dysfunction and therapeutic strategies to correct its dysfunction with the main objectives of:
1. Investigate the molecular mechanisms underlying the dysfunction of neurotrophic factors, particularly BDNF, in different pathological conditions, including Alzheimer’s disease, epilepsy, and Rett syndrome.
2. Identify new therapeutic targets related to the specific molecular alterations associated with each disease and develop innovative pharmacological strategies to reverse neurotrophic factor dysfunctions.
To do so, we work as part of a larger, interconnected research network within the Instituto de Farmacologia e Neurociência, fostering strong scientific collaboratios, working as an integral part of the Neuronal Communications and Synaptopathies Lab at the Faculdade de Medicina, Universidade de Lisboa.
