Employing human adipose-derived stem cells to propagate serum-derived hepatitis C virus and use thereof
Hepatitis C virus replication at extrahepatic sites has been suggested; however, complete viral replication has only been confirmed in hepatocytes. Here we show that human adipogenic DLK-1+ stem cells (hADSC) freshly isolated from HCV-infected individuals contained viral transcripts, replication intermediates and viral antigens in vivo, and viral transcripts increased in supernatants upon prolonged ex vivo culture. Furthermore, naive hADSC isolated from HCV (−) individuals support complete replication of clinical isolates in vitro, and the infection is donor-nonspecific for cells and cross-genotypic for viruses. Viral infection/replication is mediated through CD81, LDL-R, SR-B1, EGFR, Apolipoprotein E, occludin, claudin-1, NPC1L1 and diacylglycerol acetyltransferase-1, and can be inhibited by anti-viral drugs. In addition, the physical properties of hADSC-propagated viral particles resemble clinical isolates more than JFH1/HCVcc, and viruses propagated by in vitro infected hADSC are infectious to primary human hepatocytes. Therefore, hADSC are an in vivo HCV reservoir and represent a novel venue of clinical virus-host interaction. hADSC can also be exploited as a physiologically relevant primary cell culture system to propagate clinical isolates. |

Focused evolution of HIV-1 neutralizing antibodies revealed by crystal structures and deep sequencing
Antibody VRC01 represents a human immunoglobulin that neutralizes—˜90% of diverse HIV-1 isolates. To understand how such broadly neutralizing HIV-1 antibodies develop and recognize the viral envelope, we used X-ray crystallography and 454 pyrosequencing to characterize additional antibodies from HIV-1-infected individuals. Crystal structures revealed a convergent mode of binding of different antibodies to the same CD4-binding-site epitope. Antibody recognition was achieved through the evolution of complementary contact domains that were generated in diverse ways. Phylogenetic analysis of expressed heavy and light chains determined by deep sequencing revealed a common pathway of antibody heavy chain maturation confined to IGHV1-2*02 lineage that could pair with different light chains. The maturation pathway inferred by antibodyomics reveals that diverse antibodies evolve to a highly affinity-matured state to recognize an invariant viral structure, providing insight into the development and evolution of broadly neutralizing HIV-1 immunity. |
