Micrograph of non-alcoholic fatty liver disease (NAFLD). Masson's trichrome & Verhoeff stain. The liver has a prominent (centrilobular) macrovesicular steatosis (white/clear round/oval spaces) and mild fibrosis (green). The hepatocytes stain red. Macrovesicular steatosis is lipid accumulation that is so large it distorts the cell's nucleus. Image Credit: Nephron CC BY-SA 3.0 |
There is currently no drug for treating non-alcoholic fatty liver disease, which affects many people with type 2 diabetes and which can result in other serious liver diseases. A study led by researchers from Karolinska Institutet has now identified a drug candidate for the treatment of fatty liver. The preclinical study, published in the Journal of Hepatology, indicates that an antibody that blocks the protein VEGF-B presents a possible therapeutic option for fatty liver disease.
“Fatty liver is associated with several serious and sometimes fatal diseases,” says the study’s first author Annelie Falkevall, researcher at the Department of Medical Biochemistry and Biophysics, Karolinska Institutet, Sweden. “With the therapeutic principle that we’ve developed, it might be possible to prevent fatty liver and hopefully lower the risk of liver failure and terminal liver cancer.”
For decades, obesity and overweight have been a common global disease that, amongst other problems, has caused a sharp rise in the incidence of type 2 diabetes. According to the Swedish Diabetes Association, there are 500,000 cases of diabetes in Sweden alone, of which 85 to 90 percent are type 2.
