Patent number: 11903982Abstract: Pseudomonas aeruginosa (PA) leads to chronic respiratory infections especially in patients with cystic fibrosis patients and chronic obstructive pulmonary disease (COPD), characterized by a high morbidity. After screening Lactobacilli coming from CF expectorations, on their capacity to inhibit two Pseudomonas aeruginosa (PA) virulence factors (elastase, pyocyanin), the inventors evaluated the effect of intranasal administration of Lactobacilli on PA murine pneumonia. The primary outcome was the bacterial lung load 24 hours after PA induced pneumonia. To understand the role of Lactobacillus, the chemokines, the pro and anti-inflammatory BAL rates were also measured. The administration of Lactobacilli cocktail 18 h prior the PA lung infection decreases significantly the lung bacterial load at 24 h post-infection. Although the mechanisms need to be deeply explored, an immunomodulation effect may be involved, notably through the recruitment of neutrophils.Type: GrantFiled: May 10, 2022Date of Patent: February 20, 2024Assignees: INSERM (INSTITUT NATIONAL DE LA SANTE ET DE LA RECHERCHE MEDICALE), ETABLISSEMENT FRANCAIS DU SANG (EFS), UNIVERSITE DE BRETAGNE OCCIDENTALE, CENTRE HOSPITALIER REGIONAL ET UNIVERSITAIRE DE BRESTInventors: Rozenn Le Berre, Marie-Sarah Fangous, Gwenaelle Le Blay, Geneviève Hery-Arnaud, Rosyne Lagrafeuille

Patent number: 11773163Abstract: The present invention relates to methods and pharmaceutical compositions for the prophylactic treatment of metastases. The inventors showed in vivo that lung metastasis in GPVI deficient mice are reduced compared to controls.
