“Acute liver failure (ALF) is a life-threatening disease that has proven difficult to cure. In Western
countries, acetaminophen (APAP) poisoning is the most common cause of ALF. However, the mode of cell death in APAP-induced ALF cases is controversial. Previous studies have shown that administration of anti-interleukin-1 (anti-IL-1) antibody attenuated APAP-induced liver injury, and that administration of anti-IL-1 receptor antagonist (anti-IL-1Ra) antibody exacerbated
organ injury. These results prompted us to investigate the roles of IL-1Ra in APAP-induced ALF mice. Our results show that administration of recombinant human IL-1Ra (rhIL-1Ra) could significantly improve the survival rate of mice with ALF induced by APAP. Furthermore, we found that rhIL-1Ras could dramatically inhibit the activities of alanine aminotransferase and aspartate aminotransferase in serum, reduce the death of hepatocytes and accelerate the proliferation of hepatocytes. In addition, we show that hepatocellular apoptosis rather than necrosis was the major cause of ALF-induced animal death, and that the anti-apoptosis role of rhIL-1Ra was mediated by reducing the release of cytochrome c from the mitochondria, and the activities of caspase-3, caspase-8 and caspase-9 PU-H71 supplier in the liver tissue. In conclusion, these data indicate that rhIL-1Ra is a promising candidate for the treatment of APAP-induced ALF in mice through the reduction of hepatocellular apoptosis.

“Deimination is a
post-translational modification of proteins in which selected arginine amino acids are enzymatically converted to citrullines. Using dual-color immunofluorescence and an established monoclonal antibody (F95) against peptidyl-citrulline selleck chemicals llc moieties, the present study is the first to compare immunohistochemical staining patterns for deiminated proteins in human substantia nigra (SN) from patients with Parkinson disease (PD) versus similar control specimens supplied by the Harvard Brain Bank In control SN sections, many tyrosine hydroxylase (TH)-immunoreactive dopamine neurons were seen surrounded either by small fibers immunoreactive for deiminated proteins, or large reactive astrocytes, co-localized with glial fibrillary acidic protein (GFAP). However, in SN specimens from PD patients, immunoreactivity for deiminated proteins was also demonstrated within the cytoplasm of many surviving dopamine neurons that were also immunoreactive for TH, but this staining was not specifically restricted to Lewy bodies.
