Janus -faced liposomes enhance antimicrobial innate immune response in Mycobacterium tuberculosis infection

2012

We have generated unique asymmetric liposomes with phosphatidylserine (PS) distributed at the outer membrane surface to resemble apoptotic bodies and phosphatidic acid (PA) at the inner layer as a strategy to enhance innate antimycobacterial activity in phagocytes while limiting the inflammatory response. Results show that these apoptotic body-like liposomes carrying PA (ABL/PA) ( i ) are more efficiently internalized by human macrophages than by nonprofessional phagocytes, ( ii ) induce cytosolic Ca 2+ influx, ( iii ) promote Ca 2+ -dependent maturation of phagolysosomes containing Mycobacterium tuberculosis (MTB), ( iv ) induce Ca 2+ -dependent reactive oxygen species (ROS) production, (…

Hepatitis C virus infection as a risk factor for hepatocellular carcinoma in patients with cirrhosis. A case-control study.

1992

Objective To determine whether chronic hepatitis C virus (HCV) infection is an independent risk factor for hepatocellular carcinoma and whether it increases the cirrhosis-related risk for hepatocellular carcinoma. Design Two pair-matched case-control studies. Setting A referral-based hospital. Patients In study I, 212 patients with hepatocellular carcinoma (197 of whom had known underlying cirrhosis) were compared with controls who had chronic nonhepatic diseases. In study II, the 197 patients with hepatocellular carcinoma and cirrhosis were compared with 197 pair-matched controls who had cirrhosis but not hepatocellular carcinoma. Measurements Levels of antibody to HCV (anti-HCV), hepatiti…
