Dipeptidyl Peptidase‐4 Is a Pro‐Recovery Mediator During Acute Hepatotoxic Damage and Mirrors Severe Shifts in Kupffer Cells

Nádia Duarte, Inês Coelho, Denys Holovanchuk, Joana Inês Almeida, Carlos Penha‐Gonçalves, Maria Paula Macedo – 7 September 2018 – Dipeptidyl peptidase‐4 (DPP‐4 or clusters of differentiation [CD]26) is a multifunctional molecule with established roles in metabolism. Pharmacologic inhibition of DPP‐4 is widely used to improve glycemic control through regulation of the incretin effect. Colaterally, CD26/DPP‐4 inhibition appears to be beneficial in many inflammatory conditions, namely in delaying progression of liver pathology.

Whole‐Exome Sequencing Study of Extreme Phenotypes of NAFLD

Sarah E. Kleinstein, Matthew Rein, Manal F. Abdelmalek, Cynthia D. Guy, David B. Goldstein, Anna Mae Diehl, Cynthia A. Moylan – 5 September 2018 – Nonalcoholic fatty liver disease (NAFLD) is a heterogeneous disease with highly variable outcomes. Patients with simple steatosis typically experience a benign course, whereas those with more advanced liver injury, nonalcoholic steatohepatitis (NASH), and advanced stage fibrosis suffer increased risk for complications such as cirrhosis, hepatic decompensation, and liver cancer.

A Rare Nonsense Mutation in the Glucokinase Regulator Gene Is Associated With a Rapidly Progressive Clinical Form of Nonalcoholic Steatohepatitis

Carlos J. Pirola, Diego Flichman, Hernán Dopazo, Tomas Fernández Gianotti, Julio San Martino, Cristian Rohr, Martin Garaycoechea, Carla Gazzi, Gustavo O. Castaño, Silvia Sookoian – 5 September 2018 – We report on the presence of a rare nonsense mutation (rs149847328, p.Arg227Ter) in the glucokinase regulator (GCKR) gene in an adult patient with nonalcoholic fatty liver disease (NAFLD), morbid obesity, and type 2 diabetes; this patient developed a progressive histological form of the disease.
