  • Patent number: 11447825
    Abstract: A method for the detection of impaired responsiveness of CD4+ T-cells to regulatory T-cells (Treg), Treg resistance, by measuring the expression levels of peroxisome proliferator-activated receptor gamma coactivator 1-alpha, PPARGC1A (PGC-1?) in activated CD4+ T-cells, in particular in patients suffering from relapsing remitting multiple sclerosis. The invention relates to an in vitro screening method for the detection of an autoimmune disease or a condition, comprising the steps of generating a functional gene expression profile by measuring the expression levels of peroxisome proliferator-activated receptor gamma coactivator 1-alpha, PPARGC1A (PGC-1?) in Treg-resistant CD4+ T-cells from patients suffering of an autoimmune disease or condition, and comparing the obtained gene expression profile with the expression profile from Treg-sensitive CD4+ T-cells from healthy controls.

  • Publication number: 20080092858
    Abstract: A first fuel state determination section determines a fuel condition purged from a canister based on a quantity of deviations from a target air fuel ratio of the measured air-fuel-ratio. A second fuel state determination section determines a fuel condition after a purge control valve has closed. An abnormality detecting section detects an abnormalities of the second fuel state determination section. An air-fuel-ratio learning section performs air-fuel-ratio learning. An air-fuel-ratio-control section controls a fuel injection quantity based on the fuel condition. An initiation timing of the purge by a purge control valve is adjusted based on a history of an abnormality detection of the second fuel state determination section and a learning history of the air-fuel-ratio learning section. A fuel vapor treatment apparatus which can enlarge a purge amount enough is provided.
