    Antibody-Mediated Enhancement Aggravates Chikungunya Virus

P. Ng1,2,7 The arthropod-transmitted chikungunya virus (CHIKV) causes a fu-like disease that is characterized by incapacitating arthralgia. The re-emergence of CHIKV and the continual risk of new epidemics have reignited research in CHIKV pathogenesis. Virus-specifc antibodies have been shown to control virus clearance, but antibodies present at sub-neutralizing concentrations can also augment virus infection that exacerbates disease severity. To explore this occurrence, CHIKV infection was investigated in the presence of CHIKV-specifc antibodies in both primary human cells and a murine macrophage cell line, RAW264.7. Enhanced attachment of CHIKV to the primary human monocytes and B cells was observed while increased viral replication was detected in RAW264.7 cells. Blocking of specifc Fc receptors (FcγRs) led to the abrogation of these observations. Furthermore, experimental infection in adult mice showed that animals had higher viral RNA loads and endured more severe joint infammation in the presence of sub-neutralizing concentrations of CHIKV-specifc antibodies. In addition, CHIKV infection in 11 days old mice under enhancing condition resulted in higher muscles viral RNA load detected and death. These observations provide the frst evidence of antibody-mediated enhancement in CHIKV infection and pathogenesis and could also be relevant for other important arboviruses such as Zika virus.

  • Viral Hemorrhagic Fevers (Lassa, Marburg, Ebola, Crimean-Congo, and Other Emerging Viruses)

    Viral Hemorrhagic Fevers (Lassa, Marburg, Ebola, Crimean-Congo, and Other Emerging Viruses)

    Viral Hemorrhagic Fevers (Lassa, Marburg, Ebola, Crimean-Congo, and other emerging viruses) What Are They? Viral hemorrhagic fevers are a group of illnesses causes by several viruses. These viruses affect multiple organs in the body by damaging the vascular (blood vessel) system. The bleeding or hemorrhaging caused by the virus is not usually life threatening but damage to organ systems in the body can range from mild to deadly. The viruses responsible for this type of illness include Lassa, Marburg, Ebola, and Crimean-Congo hemorrhagic fever. How can you get it? These emerging viral hemorrhagic fevers are presumed to be animal borne (zoonotic) and can be transmitted to humans through contact. Infected humans can spread the virus to each other through contact with contaminated objects or blood. The risk of acquiring these diseases is typically restricted to the geographic regions where the virus is found. Given global travel, rare cases have been reported outside of the host region. These rare cases are probably the greatest form of the occupational threat to fire fighters. Lassa Associated with specific rodents Found in West Africa Marburg Transmitted by African fruit bat Found in Africa Ebola Transmitted by unknown animal Found in Africa Crimean-Congo Tick-borne virus Found in Africa, Asia, Europe What are the symptoms? The time to develop symptoms varies by virus but is between 2 to 21 days after exposure to the Ebola virus. The signs and symptoms of viral hemorrhagic fever vary depending on the virus but include: Flu-like symptoms o Fever o Fatigue o Muscle aches Exhaustion Nausea and/or vomiting Abdominal pain Shock Seizures Delirium Bleeding Organ failure The most common complication of Lassa fever is deafness.

    Orthohantaviruses Belonging to Three Phylogroups All Inhibit Apoptosis in Infected Target Cells

    www.nature.com/scientificreports OPEN Orthohantaviruses belonging to three phylogroups all inhibit apoptosis in infected target cells Received: 13 July 2018 Carles Solà-Riera1, Shawon Gupta1,2, Hans-Gustaf Ljunggren1 & Jonas Klingström 1 Accepted: 3 December 2018 Orthohantaviruses, previously known as hantaviruses, are zoonotic viruses that can cause hantavirus Published: xx xx xxxx pulmonary syndrome (HPS) and hemorrhagic fever with renal syndrome (HFRS) in humans. The HPS-causing Andes virus (ANDV) and the HFRS-causing Hantaan virus (HTNV) have anti-apoptotic efects. To investigate if this represents a general feature of orthohantaviruses, we analysed the capacity of six diferent orthohantaviruses – belonging to three distinct phylogroups and representing both pathogenic and non-pathogenic viruses – to inhibit apoptosis in infected cells. Primary human endothelial cells were infected with ANDV, HTNV, the HFRS-causing Puumala virus (PUUV) and Seoul virus, as well as the putative non-pathogenic Prospect Hill virus and Tula virus. Infected cells were then exposed to the apoptosis-inducing chemical staurosporine or to activated human NK cells exhibiting a high cytotoxic potential. Strikingly, all orthohantaviruses inhibited apoptosis in both settings. Moreover, we show that the nucleocapsid (N) protein from all examined orthohantaviruses are potential targets for caspase-3 and granzyme B. Recombinant N protein from ANDV, PUUV and the HFRS-causing Dobrava virus strongly inhibited granzyme B activity and also, to certain extent, caspase-3 activity. Taken together, this study demonstrates that six diferent orthohantaviruses inhibit apoptosis, suggesting this to be a general feature of orthohantaviruses likely serving as a mechanism of viral immune evasion. Orthohantaviruses, of the order Bunyavirales and previously known as hantaviruses, are small single-stranded negative-sense RNA viruses with a tri-segmented genome (S, M and L segments) encoding four to fve proteins.
