[Q]: Paragraph: The SARS 3C-like proteinase (SARS-3CLpro), which is the main proteinase of the SARS coronavirus, is essential to the virus life cycle. This enzyme has been shown to be active as a dimer in which only one protomer is active. However, it remains unknown how the dimer structure maintains an active monomer conformation. It has been observed that the Ser139-Leu141 loop forms a short 3 10 -helix that disrupts the catalytic machinery in the inactive monomer structure. We have tried to disrupt this helical conformation by mutating L141 to T in the stable inactive monomer G11A/R298A/Q299A. The resulting tetra-mutant G11A/L141T/R298A/Q299A is indeed enzymatically active as a monomer. Molecular dynamics simulations revealed that the L141T mutation disrupts the 3 10 -helix and helps to stabilize the active conformation. The coil-3 10 -helix conformational transition of the Ser139-Leu141 loop serves as an enzyme activity switch. Our study therefore indicates that the dimer structure can stabilize the active conformation but is not a required structure in the evolution of the active enzyme, which can also arise through simple mutations.

[Q]: Paragraph: Using sequence data to infer population dynamics is playing an increasing role in the analysis of outbreaks. The most common methods in use, based on coalescent inference, have been widely used but not extensively tested against simulated epidemics. Here, we use simulated data to test the ability of both parametric and non-parametric methods for inference of effective population size (coded in the popular BEAST package) to reconstruct epidemic dynamics. We consider a range of simulations centred on scenarios considered plausible for pandemic influenza, but our conclusions are generic for any exponentially growing epidemic. We highlight systematic biases in non-parametric effective population size estimation. The most prominent such bias leads to the false inference of slowing of epidemic spread in the recent past even when the real epidemic is growing exponentially. We suggest some sampling strategies that could reduce (but not eliminate) some of the biases. Parametric methods can correct for these biases if the infected population size is large. We also explore how some poor sampling strategies (e.g. that over-represent epidemiologically linked clusters of cases) could dramatically exacerbate bias in an uncontrolled manner. Finally, we present a simple diagnostic indicator, based on coalescent density and which can easily be applied to reconstructed phylogenies, that identifies time-periods for which effective population size estimates are less likely to be biased. We illustrate this with an application to the 2009 H1N1 pandemic. Pandemic growth rates from sequences E. de Silva et al. 1799 Pandemic growth rates from sequences E. de Silva et al. 1807

[Q]: Paragraph: Formalin-inactivated Japanese encephalitis virus (JEV) vaccines are widely available, but the effects of formalin inactivation on the antigenic structure of JEV and the profile of antibodies elicited after vaccination are not well understood. We used a panel of monoclonal antibodies (MAbs) to map the antigenic structure of live JEV virus, untreated control virus (UCV), formalin-inactivated commercial vaccine (FICV), and formalin-inactivated virus (FIV). The binding activity of T16 MAb against Nakayama-derived FICV and several strains of FIV was significantly lower compared to live virus and UCV. T16 MAb, a weakly neutralizing JEV serocomplex antibody, was found to inhibit JEV infection at the post-attachment step. The T16 epitope was mapped to amino acids 329, 331, and 389 within domain III (EDIII) of the envelope (E) glycoprotein. When we explored the effect of formalin inactivation on the immunogenicity of JEV, we found that Nakayama-derived FICV, FIV, and UCV all exhibited similar immunogenicity in a mouse model, inducing anti-JEV and anti-EDII 101/ 106/107 epitope-specific antibodies. However, the EDIII 329/331/389 epitope-specific IgG antibody and neutralizing antibody titers were significantly lower for FICV-immunized and FIV-immunized mouse serum than for UCV-immunized. Formalin inactivation seems to alter the antigenic structure of the E protein, which may reduce the potency of commercially available JEV vaccines. Virus inactivation by H 2 O 2 , but not by UV or by short-duration and higher temperature formalin treatment, is able to maintain the antigenic structure of the JEV E protein. Thus, an alternative inactivation method, such as H 2 O 2 , which is able to maintain the integrity of the E protein may be essential to improving the potency of inactivated JEV vaccines. We demonstrated that formalin inactivation of Japanese encephalitis virus (JEV) alters the antigenic structure of the JEV envelope glycoprotein (E), in particular an epitope in domain III, and that this reduces the ability of the inactivated vaccine to elicit protective neutralizing antibodies. Ours and others' previous studies have highlighted the importance of improving the immunogenicity of genotype III (GIII)-derived JEV vaccine in order to provide cross-protection against genotype I (GI) viruses, which are emerging and replacing GIII viruses in many JEV-endemic regions. Encouraging the wide use of live-attenuated or chimeric vaccines, such as SA14-14-2 or yellow-fever 17D/JEV vaccines, respectively, developing GI virus-derived inactivated or premembrane/E-containing, noninfectious virus-like particle (VLP) vaccines are two other possible ways to address this potential problem. In this exploratory study, we highlight an alternative inactivation method, such as H 2 O 2 treatment, which may improve the antigenic stability and immunogenicity of JEV. Japanese encephalitis virus (JEV), the most important etiological agent of viral encephalitis in Asian countries, causes regular outbreaks in eastern and southeastern Asia, India, and more recently in Australia [1,2]. Annually, 30,000 to 50,000 Japanese encephalitis (JE)-confirmed cases are reported in the JEV endemic areas, and 20% to 60% of symptomatic CNS infections are fatal [3-6]; 25% to 50% of symptomatic survivors have long-term neurological sequelae [7] . Asymptomatic JEV infection is about a thousand-fold higher than confirmed cases [8] [9] [10] . JEV is transmitted by virus-infected Culex mosquitos from inapparently infected viremic-amplifying hosts such as pigs or aquatic birds to symptomatic accidental hosts, such as horses and humans. Migratory birds have been implicated as the source of virus been introduced into new geographic regions, and associated with JE epidemics and replacement of genotype III (GIII)with genotype I (GI)-JEV from southeast Asia to east Asia [11, 12] . The genome of JEV consists of a~11-kb, positive-sense, single-stranded RNA, which is translated and processed by viral and host proteases to three structural proteins-capsid, precursor membrane/membrane protein (prM/M) and envelope glycoprotein (E)-and seven nonstructural proteins (NS)-NS1, 2A, 2B, 3, 4A, 4B and 5. The mature virion consists of 180 E proteins forming 90 homodimers and 180 processed M proteins. The immature virion is formed by 60 E and prM hetero-trimers [13, 14] . E protein is the most critical protein eliciting protective immunity in hosts after viral infection, offering critical protection in mice [15] and inducing protective antibodies in recovering humans [16] . The ectodomain of E protein can be separated into three structural domains: E domain I (EDI) to III (EDIII). The fusion peptide in EDII elicits group cross-reactive non-or low-neutralizing antibodies; EDIII, the receptor-binding domain, elicits potent type-specific neutralizing antibodies; and EDI, the center domain connecting EDII and EDIII, elicits complex cross-reactive high-or non-neutralizing antibodies after viral infection [16] [17] [18] . Vaccination remains the most effective strategy to control JE epidemics [19]. Live-attenuated and formalin-inactivated JEV vaccines are available for human use, but only live-attenuated vaccines are available for domestic animals, such as swine and horses. The first generation inactivated JEV vaccine, developed by BIKEN in Japan, was the mouse brain-derived, formalin-inactivated GIII Nakayama strain; manufacture of this vaccine has ceased since 2005 because of undesirable adverse effects [20] .
