Alzheimer's disease is characterized by the accumulation and deposition of plaques of β-amyloid (Aβ) peptide in the brain. Given its pivotal role, new therapies targeting Aβ are in demand. We rationally designed liposomes targeting the brain and promoting the disaggregation of Aβ assemblies and evaluated their efficiency in reducing the Aβ burden in(More)
Bone marrow-derived mesenchymal stem cells (MSCs) are multipotent stem cells endowed with neurotrophic potential combined with immunological properties, making them a promising therapeutic tool for neurodegenerative disorders. However, the mechanisms through which MSCs promote the neurological recovery following injury or inflammation are still largely(More)
BACKGROUND Bosutinib is a recently approved ABL inhibitor. In spite of the well-documented effectiveness of BCR-ABL inhibitors in treating chronic myeloid leukemia, development of resistance is a continuous clinical challenge. Transporters that facilitate drug uptake and efflux have been proposed as one potential source of resistance to tyrosine kinase(More)
In class A GPCRs the E/DRY motif is critical for receptor activation and function. According to experimental and computational data, R3.50 forms a double salt bridge with the adjacent E/D3.49 and E/D6.30 in helix 6, constraining the receptor in an inactive state. The disruption of this network of interactions facilitates conformational transitions that(More)
The structure-based design of a mutant form of the thromboxane A2 prostanoid receptor (TP) was instrumental in characterizing the structural determinants of the hetero-dimerization process of this G protein coupled receptor (GPCR). The results suggest that the hetero-dimeric complexes between the TPα and β isoforms are characterized by contacts between(More)
Decrease of cholesterol level in plasma membrane of living HEK293 cells transiently expressing FLAG-δ-OR by β-cyclodextrin (β-CDX) resulted in a slight internalization of δ-OR. Massive internalization of δ-OR induced by specific agonist DADLE was diminished in cholesterol-depleted cells. These results suggest that agonist-induced internalization of δ-OR,(More)
The ability of GPCRs to assemble into multimeric complexes is one of the most recently studied and discussed topics for many reasons, including the possibility that GPCR assemblies show a distinct pharmacological profile offering an innovative avenue for the drug synthesis. In addition, the possible differential coupling of monomeric versus multimeric GPCRs(More)
