Markers of Tissue Repair and Cellular Aging Are Increased in the Liver Tissue of Patients With HIV Infection Regardless of Presence of HCV Coinfection.

Abstract

Liver disease is a leading cause of HIV-related mortality. Hepatitis C virus (HCV)-related fibrogenesis is accelerated in the setting of HIV coinfection, yet the mechanisms underlying this aggressive pathogenesis are unclear. We identified formalin-fixed paraffin-embedded liver tissue for HIV-infected patients, HCV-infected patients, HIV/HCV-coinfected patients, and controls at Duke University Medical Center. De-identified sections were stained for markers against the wound repair Hedgehog (Hh) pathway, resident T-lymphocytes, and immune activation and cellular aging. HIV infection was independently associated with Hh activation and markers of immune dysregulation in the liver tissue.

Ferrari

Guido Ferrari

Professor in Surgery

The activities of the Ferrari Laboratory are based on both independent basic research and immune monitoring studies. The research revolves around three main areas of interest: class I-mediated cytotoxic CD8+ T cell responses, antibody-dependent cellular cytotoxicity (ADCC), gene expression in NK and T cellular subsets upon infection with HIV-1. With continuous funding over the last 11 years from the NIH and Bill & Melinda Gates Foundation along with many other productive collaborations within and outside of Duke, the Ferrari Lab has expanded its focus of research to include the ontogeny of HIV-1 specific immune responses that work by eliminating HIV-1 infected cells and how these can be induced by AIDS vaccine candidates.

Florence McAlister Distinguished Professor of Medicine

Our lab has a long standing interest in liver injury and repair. To learn more about the mechanisms that regulate this process, we study cultured cells, animal models of acute and chronic liver damage and samples from patients with various types of liver disease. Our group also conducts clinical trials in patients with chronic liver disease. We are particularly interested in fatty liver diseases, such as alcoholic fatty liver disease and nonalcoholic fatty liver disease (NAFLD).

Research by our group has advanced understanding in two main areas: 1) immune system regulation of liver injury and regeneration and 2)the role of fetal morphogens, such as the hedgehog pathway, in regulating fibrotic responses to liver damage. Our basic research programs have been enjoyed continuous NIH support since 1989. We welcome students, post-doctoral fellows and visiting scientists who have interests in this research area to contact us about training opportunities and potential collaborations.

Since 2001 we have also been an active participant in the NIDDK-funded Nonalcoholic Steatohepatitis Clinical Research Network (NASH CRN), a national consortium comprised of 8 university medical centers selected to generate a national registry for patients with NAFLD and to conduct multicenter treatment trials for this disorder. We are actively recruiting patients for this program, as well as a number of other industry-supported NAFLD studies.
