20230393138 · 2023-12-07 ·

The present invention provides a method for determining the prognosis of cancer in a subject. The method comprises measuring the amount of megakaryocytes in a sample from the subject. Usually, the sample is a blood sample. The method may also comprise measuring the number of circulating tumour cells (CTCs) in the sample, and in some embodiments a comparison of the number of megakaryocytes and CTCs in the sample. The present invention also provides methods of treatment for cancer in a patient for whom a poor prognosis is predicted using a method of prognosis of the invention.

METHOD FOR EVALUATION THE PRESENCE OF A VIRAL RESERVOIR

A method for the evaluation of the efficacy of a drug aiming to eradicate a cellular reservoir of mammalian cells infected with a mammalian immunodeficiency virus, the method including: a) quantifying, the presence of lymphocyte cells expressing a CD89 differentiation marker on their surface; and b) concluding that the drug is efficient to eradicate the cellular reservoir of mammalian cells infected with the mammalian immunodeficiency virus when lymphocyte cells expressing a CD89 differentiation marker are absent.

METHODS FOR DIAGNOSING HEMATOLOGICAL CANCERS

The present disclosure relates to methods for diagnosing hematological cancers. In particular, the present invention relates to a method for diagnosing a hematological cancer in a patient comprising i) detecting the presence of CD45RARO NK cells in a sample obtained from the patient and ii) and concluding that the patient suffers from a hematological cancer when the presence of CD45RARO NK cells is detected in the sample and the presence of at least one phenotypic marker indicates the nature of the haematological cancer.

Cell identification method

The present invention relates to the use of a nucleic acid molecule encoding a first reporter gene, bordered by at least one first pair and one second pair of sequences targeting a site-specific recombinase in order to detect cells of a mammal infected with a virus responsible for an immunodeficiency.

Method for detecting and typing rare tumor cells in body fluid sample and kit therefor

A method for detecting and typing rare tumor cells having high metabolic activity in a body fluid sample, comprising the following steps: incubating nucleated cells in a body fluid sample with a first metabolic marker and a second metabolic marker capable of producing fluorescence signals; detecting, by means of high-throughput imaging, uptake of all the fluorescence signals of the metabolic markers by cells, so as to determine the energy metabolism mode and intensity of the cells; and identifying and typing, according to the fluorescence signals of the metabolic marker combination, tumor cells having high metabolic activity in the body fluid sample. Further provided is a kit used for the detecting and typing method, comprising a microwell array chip, a first metabolic marker and a second metabolic marker capable of producing fluorescence signals, and fluorescence-labeled antibodies specific to leukocyte common antigen. The method and the kit identify and type energy metabolism modes of rare tumor cells in a body fluid sample based on fluorescence signal characteristics, and the operation is simple and fast, reducing the possibility of losing rare tumor cells.

METHOD FOR MEASURING CELLULAR UPTAKE OF MOLECULES
