Résumé

Differential expression analysis of single-cell transcriptomics allows scientists to dissect cell-type-specific responses to biological perturbations. Here, the authors show that many commonly used methods are biased and can produce false discoveries.

Gene expression profiling

In the field of molecular biology, gene expression profiling is the measurement of the activity (the expression) of thousands of genes at once, to create a global picture of cellular function. These profiles can, for example, distinguish between cells that are actively dividing, or show how the cells react to a particular treatment. Many experiments of this sort measure an entire genome simultaneously, that is, every gene present in a particular cell. Several transcriptomics technologies can be used to generate the necessary data to analyse.

Transcriptomique

La transcriptomique est l'étude de l'ensemble des ARN messagers produits lors du processus de transcription d'un génome. Elle repose sur la quantification systématique de ces ARNm, ce qui permet d'avoir une indication relative du taux de transcription de différents gènes dans des conditions données. Plusieurs techniques permettent d'avoir accès à cette information, en particulier celle des puces à ADN, celle de la PCR quantitative ou encore celle du séquençage systématique d'ADN complémentaires.

Immunité cellulaire

Cell-mediated immunity or cellular immunity is an immune response that does not involve antibodies. Rather, cell-mediated immunity is the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen. In the late 19th century Hippocratic tradition medicine system, the immune system was imagined into two branches: humoral immunity, for which the protective function of immunization could be found in the humor (cell-free bodily fluid or serum) and cellular immunity, for which the protective function of immunization was associated with cells.
