    Publication number: 20220003782
    Abstract: Methods for detecting and/or measuring the level of sodium-dependent multivitamin transporter (SMVT) in a biological sample. The methods include the steps of: (a) contacting the biological sample with a PERV-B.RBD ligand, a variant and/or a fragment thereof; and, detecting and/or measuring the binding of the PERV-B.RBD ligand, variant and/or fragment thereof to SMVT.

  • Identifying viral cell tropism
    Patent number: 9175334
    Abstract: The invention relates to an in vitro method for identifying microRNAs or the target mRNAs thereof, the expression of which during the infection of cells by a virus using a cell receptor and at least one cell co-receptor for entering the cell, is specifically modified on the basis of the cell co-receptor used by the virus for its entering the cells, comprising: i) determining the microRNA expression levels in a test cell expressing a receptor, a first co-receptor and at least one other co-receptor, after infection by a first virus using the first co-receptor and by at least one other virus using another co-receptor, respectively; ii) identifying the microRNAs, the expression level of which is modulated during the infection by each of the viruses in relation to the expression level in the uninfected cells; iii) comparing the thus-identified microRNAs; iv) selecting the microRNAs, the modification of the expression level of which is specific to the use of a co-receptor; v) optionally identifying the target mR

  • METHODS FOR DETERMINING THE TROPISM AND RECEPTOR USAGE OF A VIRUS, IN PARTICULAR HIV, IN BODY SAMPLES TAKEN FROM THE CIRCULATION
    Publication number: 20150057173
    Abstract: The present invention relates to microarrays, sets of primers and methods for determining the co-receptor usage of a virus, in particular whether HIV uses CXCR4 or CCR5 as co-receptor. The methods and compositions of the invention are based on microRNA analysis. The invention can be used to determine virus tropism in any species or organism that expresses microRNAs, particularly in human beings.
