Oxaloacetate Protects Rat Liver From Experimental Warm Ischemia/Reperfusion Injury by Improving Cellular Energy Metabolism

Grégory Merlen, Valérie‐Ann Raymond, Shamir Cassim, Pascal Lapierre, Marc Bilodeau – 21 January 2019 – Liver ischemia/reperfusion injury (IRI) is an important cause of liver damage especially early after liver transplantation, following liver resection, and in other clinical situations. Using rat experimental models, we identified oxaloacetate (OAA) as a key metabolite able to protect hepatocytes from hypoxia and IRI. In vitro screening of metabolic intermediates beneficial for hepatocyte survival under hypoxia was performed by measures of cell death and injury.

Lymphocyte Antigen 6 Complex, Locus C+ Monocytes and Kupffer Cells Orchestrate Liver Immune Responses Against Hepatitis B Virus in Mice

Li‐Ling Wu, Wei‐Hao Peng, Hui‐Lin Wu, Shi‐Chuen Miaw, Shiou‐Hwei Yeh, Hung‐Chih Yang, Pei‐Hsuan Liao, Jing‐Shan Lin, Yan‐Rong Chen, Yen‐Tien Hong, Hurng‐Yi Wang, Pei‐Jer Chen, Ding‐Shinn Chen – 19 January 2019 – To understand the mechanism(s) of age‐dependent outcomes of hepatitis B virus (HBV) infection in humans, we previously established an age‐related HBV mouse model in which 6‐week‐old (N6W) C3H/HeN mice exhibited virus tolerance whereas 12‐week‐old (N12W) counterparts presented virus clearance.

The Role of Complement in Liver Injury, Regeneration, and Transplantation

Ebbe Billmann Thorgersen, Andreas Barratt‐Due, Håkon Haugaa, Morten Harboe, Søren Erik Pischke, Per H. Nilsson, Tom Eirik Mollnes – 17 January 2019 – The liver is both an immunologically complex and a privileged organ. The innate immune system is a central player, in which the complement system emerges as a pivotal part of liver homeostasis, immune responses, and crosstalk with other effector systems in both innate and adaptive immunity. The liver produces the majority of the complement proteins and is the home of important immune cells such as Kupffer cells.
