Publication number: 20240010990Abstract: The present invention concerns a novel in vitro assay for determining the invasive ability of brain tumour cells, in particular brain tumour stem cells. This new assay, called 3D invasion assay, is based on the analysis and comparison of the area of neurospheres grown in vitro into a Matrigel extracellular-like matrix. The invention also concerns the use of said assay for diagnosing metastatic brain tumour in subjects, for determining its prognosis, as well as for the monitoring, for the stratification, for identifying subjects at risk of metastasis, and/or predicting the metastasis-associated risk in subjects diagnosed with brain tumour.Type: ApplicationFiled: September 14, 2021Publication date: January 11, 2024Applicant: Institut Gustave RoussyInventors: David CASTEL, Marie Anne DEBILY, Jacques GRILL, Marco BRUSHI

Publication number: 20230302031Abstract: The inventors herein show that purinergic receptors regulate the conversion of macrophage pro-inflammatory reprogramming into anti-inflammatory phenotype in patients suffering from COVID-19 disease. Moreover, they show that P2Y receptor agonists repress NLRP3 inflammasome-dependent IL-1b secretion, but also impair the replication and the cytopathogenic effects of SARS-CoV-2. These results therefore suggest that some purinergic receptors agonists can treat acute lung injury and respiratory disease that are associated with SARS-CoV-2 infection. In addition, their results show that antagonists of the purinergic receptors P2X impair the replication of said virus. The present invention therefore proposes to use purinergic receptors modulators and NLR3-P2Y2R immune checkpoint modulators to treat patients suffering from a virus-induced acute respiratory distress syndrome.Type: ApplicationFiled: June 1, 2021Publication date: September 28, 2023Applicant: Institut Gustave-RoussyInventors: Jean-Luc PERFETTINI, Deborah LECUYER, Desiree TANNOUS, Awatef ALLOUCH, Oliver DELELIS, Frederic SUBRA

Patent number: 11732303Abstract: The present inventors identified for the first time a germline genomic alteration that accounts for familial myeloproliferative neoplasms (MPN) and myeloid malignancies. More precisely, they identified a 700 kb germline duplication that proposes patients to essential thrombocythemia (ET) with a high frequency of evolution to myelofibrosis (MF), secondary myelodysplastic syndromes (MDS) or acute myeloid leukemia (AML). Two out of the 6 duplicated genes (namely ATG2B and GSKIP) have been shown to be overexpressed in hematopoietic progenitors, and this overexpression cooperates with classical mutations in JAK2, MPL, and CALR to generate the MPN phenotype. The presence of the 700 kb germline duplication is thus of poor prognosis for a MPN patient. The present invention discloses a method for detecting a predisposition of developing a MPN, as well as a prognostic method for assessing the probability that an ET-suffering patient will develop a myelofibrosis, a secondary MDS or an AML.Type: GrantFiled: June 24, 2016Date of Patent: August 22, 2023Assignee: Institut Gustave-RoussyInventors: Christine Bellane-Chantelot, Isabelle Plo, William Vainchenker, Cécile Saint-Martin, Antonio D Di Stefano, Joseph Saliba

Patent number: 11684640Abstract: The invention relates to gut microbiota profiles associated with response or resistance to treatments with ICB, in particular with anti-PD1 or anti PD-L1 or anti-PD-L2 antibodies. In particular, the invention pertains to a theranostic method for identifying good responders, to whom an anti-PD1 or anti PD-L1 or anti-PD-L2 can be administered, while a pre-treatment based on FMT and/or immunogenic probiotics is recommended to bad responders exhibiting a dysbiosis. In particular, the present invention pertains to Akkermansia muciniphila as the main commensal species distinguishing responders from progressors and its use alone or with E. hirae for the treatment of antibiotics or gut repertoire insufficiency-associated dysbiosis.Type: GrantFiled: December 22, 2017Date of Patent: June 27, 2023Assignees: INSTITUT GUSTAVE ROUSSY, INSTITUT NATIONAL DE LA SANTE ET DE LA RECHERCHE MEDICALE - INSERM, UNIVERSITE PARIS-SACLAY, Insitut national de recherche pour l'agriculture, l'alimentation et l'environnement (INRAE)Inventors: Laurence Zitvogel, Bertrand Routy, Emmanuelle Le Chatelier

Patent number: 11603568Abstract: Although tumor-associated macrophages have been extensively studied in the control of response to radiotherapy, the molecular mechanisms involved in the ionizing radiation-mediated activation of macrophages remain elusive. Here the present inventors show that ionizing radiation induces the expression of interferon-regulatory factor 5 (IRF5) promoting thus macrophage activation toward a pro-inflammatory phenotype. They reveal that the activation of the Ataxia telangiectasia mutated (ATM) kinase is required for ionizing radiation-elicited macrophage activation, but also for macrophage reprogramming after treatments with ?-interferon, lipopolysaccharide or chemotherapeutic agent (such as cis-platin), underscoring the fact that the kinase ATM plays a central role during macrophage phenotypic switching toward a proinflammatory phenotype. They further demonstrate that NADPH oxidase 2 (NOX2)-dependent ROS production is upstream to ATM activation and is essential during this process.Type: GrantFiled: September 19, 2017Date of Patent: March 14, 2023Assignee: Institut Gustave RoussyInventors: Jean-Luc Perfettini, Eric Deutsch, Awatef Allouch

Publication number: 20220257709Abstract: Identification of effective targets alleviating the programmed cell removal (PrCR) of tumor cells by macrophages is of very high interest. The present inventors have identified that the cyclin-dependent kinase inhibitor p21 protein is a strong regulator of the macrophage-mediated PrCR. Also, they showed that the adoptive transfer of p21 overexpressing monocytes induces macrophage PrCR and transition from an anti-inflammatory to a pro-inflammatory phenotype in vivo, delays cancer progression and increases significantly the overall survival of mice engrafted with cancer cells. The present invention therefore concerns therapeutic compositions comprising monocytes that over-express the cyclin-dependent kinase inhibitor p21 protein, and their use for treating mammals suffering from cancer, especially leukemia.Type: ApplicationFiled: July 17, 2020Publication date: August 18, 2022Applicant: Institut Gustave-RoussyInventors: Jean-Luc PERFETTINI, Awatef ALLOUCH, Eric DEUTSCH
