Impaired Kupffer Cell Self-Renewal Alters the Liver Response to Lipid Overload during Non-alcoholic Steatohepatitis

2020

International audience; Kupffer cells (KCs) are liver-resident macrophages that self-renew by proliferation in the adult independently from monocytes. However, how they are maintained during non-alcoholic steatohepatitis (NASH) remains ill defined. We found that a fraction of KCs derived from Ly-6C+ monocytes during NASH, underlying impaired KC self-renewal. Monocyte-derived KCs (MoKCs) gradually seeded the KC pool as disease progressed in a response to embryo-derived KC (EmKC) death. Those MoKCs were partly immature and exhibited a pro-inflammatory status compared to EmKCs. Yet, they engrafted the KC pool for the long term as they remained following disease regression while acquiring matur…

Effet anti-obésité des CLA : mythe ou réalité ?

2005

Conjugated linoleic acids (CLA) are positional and geometric isomers of linoleic acid. Inclusion of CLA in the diet provokes a rapid and marked decrease in body weight gain and adiposity in mice leading to a lipoatrophic syndrome. However, CLA supplementation raised fasting blood glucose and insulin concentrations and was associated with severe insulin resistance and liversteatosis. Conflicting results have been reported with regard to reduction of fat mass in humans. We have reviewed the publish literature regarding the effect of CLA on body composition in humans and animal models. These studies indicate that t10-c12 was the isomer that reduced adipose fat storage, however it also increase…
