  • Publication number: 20260191940
    Abstract: Lymphoid leukemia such as acute lymphoblastic leukemia (ALL) represents a devastating disease especially when it occurs in adults. While dose-intensification strategies have led to a significant improvement in outcomes for pediatric patients, prognosis for the elderly remains very poor, with only 30-40% of adult patients with ALL achieving long-term remission. Novel tumor-specific antigens (TSAs) shared by a large proportion of lymphoid leukemia cells are described herein. Most of the TSAs described herein derives from aberrantly expressed unmutated genomic sequences, such as intronic and intergenic sequences, which are not expressed in normal tissues. Nucleic acids, compositions, cells and vaccines derived from these TSAs are described. The use of the TSAs, nucleic acids, compositions, cells and vaccines for the treatment of leukemia such as lymphoid leukemia is also described.

  • Publication number: 20250067699
    Abstract: A device for characterizing a medium MUT by capacitance spectroscopy and applies, according to its different aspects, to at least partially-conductive media. The conductivity ? of the medium to be characterized may be deduced from the measurement of the equivalent electrical capacitance Cx and/or the equivalent conductance Gx, by means of a model of the electrical behaviour of the medium to be characterized relating said measurements both to the complex dielectric permittivity ?*(?) of the medium to be characterized and to the involved electrode surfaces.

  • Publication number: 20240382590
    Abstract: Cancer stem cells (CSCs) are a subpopulation of tumor cells that can drive tumor initiation and can cause relapses. These cells are seen as drivers of tumor establishment and growth, often correlated to aggressive, heterogeneous and therapy-resistant tumors. Novel tumor-specific antigens (TSAs) and tumor-associated antigens (TAAs) specifically expressed by CSCs are described herein. Most of the TSAs described herein derives from aberrantly expressed unmutated genomic sequences, such as intronic and intergenic sequences, which are not expressed in normal tissues. Nucleic acids, compositions, cells, antibodies and vaccines derived from these TSAs are described. The use of the TSAs, nucleic acids, compositions, antibodies, cells and vaccines for the treatment of cancer, and more particularly cancers associated with the presence of CSCs such as poorly differentiated cancers, is also described.

  • Patent number: 11747186
    Abstract: A device comprises at least one pair of excitation electrodes forming a capacitor; a floorplan (e.g., a ground plane); and an electronic circuit. The device comprises at least one control electrode arranged at a distance from the capacitor. A switching circuit, of the device, comprises a switch having an open state and a closed state. The switching circuit is designed to apply, to the control electrode, an electric potential common to the floorplan when the switch is in the closed state. The switching circuit is also designed to leave a floating electrical potential for the control electrode when the switch is in the open state. The electronic circuit is designed to measure the mutual capacitance between the pair of excitation electrodes when the switch is in the open state and when it is in the closed state.

  • Publication number: 20230242583
    Abstract: T cells, notably CD8 T cells, are known to be essential players in tumor eradication as the presence of tumor-infiltrating lymphocytes (TILs) in several cancers positively correlates with a good prognosis. To eliminate tumor cells, CD8 T cells recognize tumor antigens, which are MHC I-associated peptides present at the surface of tumor cells, with no or very low expression on normal cells. Described herein a proteogenomic approach using RNA-sequencing data from cancer and normal-matched mTEChi samples in order to identify non-tolerogenic tumor-specific antigens derived from (i) coding and non-coding regions of the genome, (ii) non-synonymous single-base mutations or short insertion/deletions and more complex rearrangements as well as (iii) endogenous retroelements, which works regardless of the sample's mutational load or complexity.

  • Publication number: 20220354937
    Abstract: Ovarian cancer, notably high-grade serous ovarian cancer (HGSC), the principal cause of death from gynecological malignancies in the world, has not significantly benefited from recent progress in cancer immunotherapy.

  • Publication number: 20220170775
    Abstract: A device, for capacitive measurement of a height of a fluid in a tank, comprises at least one pair of capacitors extending in a longitudinal direction. A first capacitor forms first geometric patterns defining a first line capacitance. A second capacitor is opposite the first capacitor and forms second geometric patterns defining a second line capacitance. The first and second geometric patterns are arranged so that the first and second line capacitances, integrated in the longitudinal direction, have a sum that depends on the position of the fluid in the longitudinal direction. The first and second line capacitances, integrated in the longitudinal direction, have a difference that is a constant for reference positions of the fluid in the longitudinal direction.
