A new player in the battle against hepatitis prevents inflammation and the death of liver cells
...colleagues from this team have shown that an extra dose
of ABIN-1 provides a double protection to liver cells in mice. With an elevated production of ABIN-1, this protein will neutralize the inflammation caused by NF-B and also prevent the complete death of liver cells after induction by TNF. ABIN-1 in t...
