herpesviruses enhance fibrin clot lysis. | the incorporation of virus- and host-derived procoagulant factors initiates clotting directly on the surface of herpesviruses, which is an explanation for their correlation to vascular disease. the virus exploits the resulting thrombin to enhance infection by modulating the host cell through protease activated receptor (par) 1 signalling. prior reports demonstrated that at least one herpesvirus expresses surface annexin a2 (a2), a cofactor for tissue plasminogen activator (tpa)-dependent activat ... | 2012 | 22318336 |
correlating flavivirus virulence and levels of intrinsic disorder in shell proteins: protective roles vs. immune evasion. | computational analyses revealed correlations between the intrinsic disorder propensity of shell proteins and case fatality rates (cfrs) among flaviviruses and within at least two flavivirus species, such as tick-borne encephalitis virus (tbev) and dengue virus (denv). the shell proteins analyzed in this study are capsid (c) and membrane (prm, pr, and m) proteins. the highest correlations can be found when regression analyses were conducted using pr (flavivirus: r(2) = 0.78, p < 0.01) or m (flavi ... | 2016 | 27102744 |
viral infections in mice with reconstituted human immune system components. | pathogenic viruses are often difficult to study due to their exclusive tropism for humans. the development of mice with human immune system components opens the possibility to study those human pathogens with a tropism for the human hematopoietic lineage in vivo. these include hcmv, ebv, kshv, hiv, htlv-1, dengue virus and jc virus. furthermore, some human pathogens, like hsv-2, adenovirus, hcv, hbv and influenza a virus, with an additional tropism for somatic mouse tissues or for additional tra ... | 2014 | 24953718 |
