The synthesis of heterologous proteins in lactobacilli is strongly influenced by the promoter selected for the expression. In addition, the activity of the promoters themselves may vary among different bacterial hosts. Three different promoters were investigated for their capability to drive enhanced green fluorescent protein (EGFP) expression in(More)
The gut microbiota has been shown to be involved in host energy homeostasis and diet-induced metabolic disorders. To gain insight into the relationships among diet, microbiota and the host, we evaluated the effects of a high-fat (HF) diet on the gut bacterial community in weaning mice. C57BL/6 mice were fed either a control diet or a diet enriched with soy(More)
Mice fed long-term high-fat diets (HFD) are an established model for human metabolic disorders, such as obesity and diabetes. However, also the effects of short-term HFD feeding should be investigated to understand which are the first events that trigger the onset of a pre-disease condition, the so-called metabolic syndrome, that increases the risk of(More)
The clustered regularly interspaced short palindromic repeat (CRISPR)/associated 9 (Cas9) technology has been recently added to the tools allowing efficient and easy DNA targeting, representing a very promising approach to gene engineering. Using the CRISPR/Cas9 system we have driven the integration of exogenous DNA sequences to the X-linked Hprt gene of(More)
Influenza A virus is the principal agent responsible of the respiratory tract's infections in humans. Every year, highly pathogenic and infectious strains with new antigenic assets appear, making ineffective vaccines so far developed. The discovery of RNA interference (RNAi) opened the way to the progress of new promising drugs against Influenza A virus and(More)
At weaning, piglets are exposed to many stressors, such as separation from the sow, mixing with other litters, end of lactational immunity, and a change in their environment and gut microbiota. The sudden change of feeding regime after weaning causes morphological and histological changes in the small intestine which are critical for the immature digestive(More)
Cell fusion between neoplastic and normal cells has been suggested to play a role in the acquisition of a malignant phenotype. Several studies have pointed to the macrophage as the normal partner in this fusion, suggesting that the fused cells could acquire new invasive properties and become able to disseminate to distant organs. However, this conclusion is(More)
Genomic disorders resulting from large rearrangements of the genome remain an important unsolved issue in gene therapy. Chromosome transplantation, defined as the perfect replacement of an endogenous chromosome with a homologous one, has the potential of curing this kind of disorders. Here we report the first successful case of chromosome transplantation by(More)
