摘要:
The invention relates to protein ZnT-8 which is specifically expressed in the pancreatic beta cells in islets of Langerhans, to a polynucleotide encoding said protein which is involved in the maturation and exocytosis of insulin, and to the applications thereof, for example, for sorting and studying beta cells and for screening medicine acting on diabetes and hyperinsulinism.
摘要:
The invention concerns a method for in vitro propagation of the agent responsible for transmissible spongiform encephalopathies, or prion, comprising steps which consist in: providing a culture or a glial cell line and in infecting the culture or line with the agent responsible for transmissible spongiform encephalopathies or prion. Said method enables to obtain infected cell lines capable of being used to assess the efficacy of a molecule in the reduction or inhibition of the infectiosity of the prion or for detecting the prion.
摘要:
The invention concerns a method for screening immunogenic peptides using Brefeldin A to enhance the effect of presentation of said peptides by antigen-presenting cells. The invention also concerns immunogenic peptides obtainable by said method, in particular peptide P100, and the use of a peptide P100 compound for preparing a medicine designed to treat and/or prevent EBV-induced diseases, in particular for treating and/or preventing Burkitt lymphoma, nasopharyngeal carcinoma, and/or Hodgkin's disease.
摘要:
The present invention relates to a method for producing a molecule of interest in bacteria which is based on a reversible growth arrest of the bacteria at the cellular growth global control system level, thus allowing an improved yield of production of said molecule of interest.
摘要:
The present invention concerns a method for the identification of the presence or absence of cancer cells in a biological sample, more particularly a method for the identification of the susceptibility or resistance to a treatment with CD20 agonists of cancer cells in a biological sample, said methods comprising determining the level of expression of the gene Cyclon in said cells and comparing said level of expression to the level of expression in a non-cancer cell, wherein a level of expression higher than the level of expression in a non-cancer cell is an indication of the presence of a cancer cell, more particularly an indication of cancer cells with a resistance to treatment with antagonists. The invention also concerns kits for the determination of a level of expression of the Cyclon gene in a biological sample, a method for the identification of Cyclon expression antagonists, as well as methods for treating patients in need thereof with CD20 agonists when the patients are identified to be susceptible to such a treatment and/or treating patients in need thereof with a combination of a Cyclon inhibitor and a CD20 agonists.
摘要:
The invention is related to a process for obtaining an adapted strain of Pseudomonas, comprising the following steps: • deleting the genes ExoS ExoT, aroA and lasI in an initial Pseudomonas strain cultivated in a LB medium, • progressively cultivating this strain in a chemically defined medium based on a glucose minimal medium supplemented with magnesium and calcium,
wherein the adapted strain presents the same toxicity and secretion capacities than the initial strain, and its doubling time when cultivated in said chemically defined medium is less than 60 minutes. The present invention is also related to the adapted strain such as obtained,in particular wherein the adapted strain is furthermore treated to become 'killed but metabolically active'.
摘要:
The present invention relates to a surgical instrument (1) for sampling molecules from an organ to which access is possible directly or via a surgical approach, including: a device (5) for capturing said molecules, a stylus (4) supporting said capture device (5) and which is capable of penetrating the organ, and a guide (3) for inserting the stylus (4) into the body up to the organ, characterized in that the distal end of the guide (3) is provided with a damping block (6) intended to bear against the organ.
