The blood-brain barrier (BBB) is a tightly regulated interface in the Central Nervous System (CNS) that regulates the exchange of molecules in and out from the brain thus maintaining the CNS homeostasis. It is mainly composed of endothelial cells (ECs), pericytes and astrocytes that create a neurovascular unit (NVU) with the adjacent neurons. Astrocytes are(More)
N-methyl-D-aspartate ionotropic glutamate receptor (NMDARs) is a ligand-gated ion channel that plays a critical role in excitatory neurotransmission, brain development, synaptic plasticity associated with memory formation, central sensitization during persistent pain, excitotoxicity and neurodegenerative diseases in the central nervous system (CNS). Within(More)
Rotenone is one of the most-studied neurotoxic substances as it induces oxidative stress processes both in cellular and animal models. Rotenone affects ATP generation, reactive oxygen species (ROS) production, and mitochondrial membrane potential in neurons and astrocyte-like cells. Previous epidemiologic studies have supported the role of neurotrophic(More)
Platelet-derived growth factor receptor alpha (PDGFRalpha) interacts with PDGFs A, B, C and AB, while PDGFRbeta binds to PDGFs B and D, thus suggesting that PDGFRalpha is more promiscuous than PDGFRbeta. The structural analysis of PDGFRalpha-PDGFA and PDGFRalpha-PDGFB complexes and a molecular explanation for the promiscuity of PDGFRalpha and the(More)
