CELL MEDIATED IMMUNE RESPONSE ASSAY WITH ENHANCED SENSITIVITY Russian patent published in 2018 - IPC G01N33/68 G01N33/53 

FIELD: medicine.

SUBSTANCE: group of inventions relates to immunology, and can be used for measuring cell-mediated immune response activity in a subject. Method comprises coincubation of a sample comprising lymphocytes from the subject, with at least two sets of peptides, derived from the protein antigen. First set being detected by CD8⁺ lymphocytes comprises at least one peptide of from 7 to 14 amino acid residues. Second set being detected by CD4⁺ lymphocytes comprises one peptide of 16 or more amino acid residues. Peptides cover the entire length of the protein antigen or a portion of the protein antigen. Presence or elevation in the level of an immune effector molecule from effector T-cells is measured. Presence or level of the immune effector molecule for T-cells is indicative of the level of cell-mediated responsiveness of the subject. Use and a method for determining the status of cell- mediated immuno responsiveness of a subject are also provided.

EFFECT: group of inventions allows to measure the general cell-mediated immune response from CD4⁺ and from CD8⁺ lymphocytes, by increasing the sensitivity and specificity of the measurement method.
