Distribution and Function of Gap Junction Coupling in Cortical GABAergic Neurons.
2013
Although gap junctions have been observed in GABAergic interneurons of several brain regions, this chapter focuses on the distribution and functions of gap junctions and connexins in inhibitory interneurons of the cerebral cortex and hippocampus. Evidence for interconnections mediated by electrical synapses is reported for at least eight cerebral cortex interneuron types, classified on the basis of morphology, electrophysiology and molecular markers. The main differences in the organization of these interneuronal networks are summarized in terms of homologous and heterologous electrical coupling and mutual chemical inhibition. The role of connexin36 (Cx36) in forming neuronal electrical syn…

Glycated albumin is correlated to insulin resistance and β-cell secretory function in subjects at risk for developing diabetes
2018
Insulin resistance and β-cell secretory function represent two main issues in the pathogenesis of type 2 diabetes mellitus (T2DM). Conflicting results have been obtained about the association between glycated albumin (GA) and body mass index (BMI), insulin resistance and β-cell function in diabetic patients. Actually, the relationship (if any) between GA and the markers of glucose homeostasis and insulin resistance in subjects at risk of developing diabetes, has not been completely elucidated yet. Two hundred and one patients undergoing to oral glucose tolerance test (OGTT) were enrolled in the study. Routine laboratory tests, including fasting insulin, were performed at enrollment. GA was …

Idrogeli a base di xyloglucano per la produzione di medicazioni avanzate nel trattamento delle ferite
2018
In questo lavoro sono stati preparati film sottili di idrogelo (reticolati fisicamente o chimicamente) a base di xyloglucano (XG) e XG/polivinilalcol (PVA), a cui si è aggiunto glicerolo come plasticizzante. Lo xyloglucano è un polisaccaride di origine vegetale, caratterizzato da una catena principale di (1,4)--Dglucosio con ramificazioni laterali di (1-6)-α-xilosio, parzialmente sostituite con (1-2)–β galattosio. E’ stata indagata la possibilità di modulare la densità di reticolazione dell’idrogelo per ottenere il miglior compromesso tra resistenza meccanica e flessibilità, l’integrità strutturale nel tempo e la capacità di assorbire fluidi biologici o trattenere l’umidità. Inoltre, ne è …

NF-kB è un fattore di trascrizione eucariotico e ubiquitario che regola l’espressione di geni coinvolti in molteplici processi cellulari come la risposta immunitaria, la flogosi, l’apoptosi, la crescita cellulare e lo sviluppo embrionale. Le proteine appartenenti alla famiglia di NF-kB sono p65, c-Rel, RelB, p50 e p52. Tali proteine svolgono la funzione di fattori trascrizionali legando specifiche consensus del DNA (consensus kB) sotto forma di omo - eterodimeri. Ogni membro della famiglia di NF-kB è caratterizzato dalla presenza di un dominio, altamente conservato, il “Rel Homology Domain” (RHD). Nel RHD sono stati mappati i sottodomini di dimerizzazione, interazione con gli inibitori (IkB…
A novel putative interactor for the low density lipoprotein receptor cytoplasmic domain
2011
Familial hypercholesterolemia (FH) is a genetic disease mainly caused by mutations in the low density lipoprotein receptor (LDLLDLLDL-R) gene. However, FH-like phenotypes may also arise from mutations occurring in other genes, the products of which normally interact with the LDLLDLLDL receptor. Although several FH-associated proteins have been discovered, many FH-like phenotypes cannot be linked to mutations in already characterized genes, suggesting the existence of other genes still to be identified, the mutations of which may be directly linked to the FH disorder. In order to identify new putative LDLLDLLDLr interactors possibly involved in its internalization and/or sorting, the cytopla…
Long non-coding RNAs during embryogenesis of the sea urchin
2014
Intriguing studies suggest that long non-coding RNAs (lncRNAs) tend to act in cis with neighboring protein-coding genes. Based on this notion, we assessed whether lncRNAs originate from adjacent genomic regions of selected protein-coding genes, such as early-H2A histone and strim1, that play important functions during development of the sea urchin Paracentrotus lividus. Downregulation of H2A expression relies on the sns5 chromatin insulator placed at the 3'-end of H2A. Northern blot hybridization show that a lncRNA (of ~600 nt), not overlapping with the H2A mRNA, is transcribed from sns5, following H2A expression. The strim1 locus encodes the first echinoderm TRIM-containing factor which fu…
