Abstract
Le lupus érythémateux disséminé (SLE) est une maladie auto-immune dans laquelle des complexes immuns circulants peuvent provoquer différents types de glomérulonéphrite, en fonction des dépôts immunitaires et du type de lésion des cellules glomérulaires. Les lésions prolifératives représentent la forme la plus sévère de la néphrite lupique (LN) et conduisent souvent à une insuffisance rénale et à la mort. Les lymphocytes T invariants associés aux muqueuses (MAIT) sont un sous-ensemble de lymphocytes T de type inné qui reconnaissent des ligands d'origine microbienne à partir de la voie de synthèse de la riboflavine. Les inventeurs ont désormais analysé le phénotype et la fonction des lymphocytes MAIT du sang périphérique par cytométrie en flux chez 26 patients souffrant de LN et dans un groupe témoin de 16 volontaires en bonne santé. Les inventeurs ont découvert que les fréquences des lymphocytes MAIT sont nettement réduites dans le sang des patients LN. Plus particulièrement, parmi les patients LN, la fréquence de base des lymphocytes MAIT, l'expression de Ki-67 évaluant l'activité proliférative et la production de granzyme B mesurant la cytotoxicité représentent des facteurs pronostiques prometteurs de la réponse rénale un an après une thérapie par induction. En conclusion, les inventeurs ont montré que la fréquence de base et le profil cytotoxique des lymphocytes MAIT peuvent représenter un facteur de pronostic prometteur de rémission rénale un an après une thérapie par induction.
