[Chronic liver immunologic factors in ischemic type biliary lesions (ITBL) --> reduced Th1 and increased Th2 response].

Compared to patients with a stable liver function, we found a decreased Th1 and increased Th2 response in patients presenting with ischemic type biliary lesions following liver transplantation. It remains open to speculation whether these immunological changes were induced by the damage of the bile ducts, occur as an additional damaging factor or are found as an epiphenomenon in patients with liver transplant dysfunction.
