Current models of G protein-coupled receptors (GPCRs) signaling describe binding of external agonists to cell surface receptors which, in turn, trigger several biological responses. New paradigms indicate that GPCRs localize to and signal at the nucleus, thus regulating distinct signaling cascades. The formyl-peptide receptor FPR2 belongs to the GPCR(More)
Bardet-Biedl syndrome (BBS) is a rare genetic disorder that features retinal degeneration, obesity, polydactyly, learning disabilities and renal abnormalities. The diagnosis is often missed at birth, the median age at diagnosis being 9 years. In the attempt to shed light on BBS and improve its diagnosis and treatment, we evaluated the genotype-phenotype(More)
G protein-couped receptors (GPCRs) play a key role on cellular membranes, where they respond to a broad array of extracellular signals such as lipids, peptides, proteins and sensory agents. Intracellular biological responses triggered by these receptors include hormone secretion, muscle contraction, cellular metabolism a tyrosine kinase receptors(More)

Lamellar ichthyosis is a rare congenital disorder characterized by collodion membrane at birth and facial anomalies (eclabium and ectropion). The major underlying genetic defect is in TGM1, with mutations of this gene found in 50% of patients. An early diagnosis is fundamental in view of establishing a specific treatment due to the severity of the disease.(More)
Exon deletions in the human DMD gene, which encodes the dystrophin protein, are the molecular defect in 50-70% of cases of Duchenne/Becker muscular dystrophies. Deletions are preferentially clustered in the 5' (exons 2-20) and the central (exons 45-53) region of DMD, likely because local DNA structure predisposes to specific breakage or recombination(More)
