Depletion of RanBP2 negatively affects HIV-1 and HIV-2 infection and nuclear import . Although HIV-1 can use other redundant pathways for import, pathways not involving RanBP2 lead to suboptimal chromosomal integration sites for the HIV-1 genome .

What is the suggested role of RANBP2 in the cell?
[ "Title: Human core duplicon gene families: game changers or game players?\nPassage: The RANBP2 protein encoded by the progenitor gene is primarily localized within the periphery of the nuclear envelope and is thought to be required for cargo import and export . Hence, the RGPD gene family members may be modifiers of this function. Interestingly, RANBP2 was also shown to be involved in resistance against Simian Immunodeficiency Virus . It is thus possible that the expansion of RGPD genes is the result of an arms race between virus evolution and host resistance acquisition.

Alphaviruses represent a group of widely distributed human and animal pathogens, which pose a serious public health threat . Some of them induce febrile and arthritogenic diseases, while others can cause highly debilitating diseases, such as encephalitis.

What is an example of containment phase intervention?
[ "Title: School closures during the 2009 influenza pandemic: national and local experiences\nPassage: In the early phase of the pandemic, HK implemented aggressive strategies to attempt to contain and later on to mitigate the spread the virus. Once the first case due to indigenous transmission was confirmed on 10 June 2009, they moved from a \"containment phase\" to a \"mitigation phase\" designed to relieve disease burden and mortality, primarily based on NPI . The mitigation phase included: public health campaigns , medical resource mobilization, opening of eight designated fever clinics , and antiviral treatment of confirmed cases. In addition, there was an immediate proactive closure of kindergarten/primary schools for at least 2 weeks", "Title: Breaking the Waves: Modelling the Potential Impact of Public Health Measures to Defer the Epidemic Peak of Novel Influenza A/H1N1\nPassage: It has been shown before that so called targeted layered containment strategies, a combination of antiviral prophylaxis and non-pharmaceutical interventions, can be effective in reducing the transmission of pandemic influenza . We extended this approach by analyzing the effect of a more intensive phase including contact tracing, identification and management of contacts outside of the household , followed by household centred measures .", "Title: Modeling the effect of comprehensive interventions on Ebola virus transmission\nPassage: measures are a combination of early diagnosis, case isolation, contact precaution, awareness campaigns, and sanitary burial practices. Identifying infected people quickly by the polymerase chain reaction assay and isolating them to break chains of EVD transmission may be effective to control the outbreak. The effect of reducing the time between symptoms onset and diagnosis with rapid testing has also been investigated in the literature .", "Title: Logistics of community smallpox control through contact tracing and ring vaccination: a stochastic network model\nPassage: Finally, scenario e demonstrates that containment is still possible even when the vaccine is completely ineffective in everyone -because of case isolation and isolation of contacts . Here, with 40 contact tracings possible per day, 55% of the replications nevertheless exhibited containment even with a vaccine which offered no protection whatever. With 90 contact tracings possible per day, all replications exhibited containment even assuming no vaccine protection." ]

How does cell-mediated immunity to viral delivery vector, reduce the immune response to vaccine?
[ "Title: Pre-existing immunity against vaccine vectors – friend or foe?\nPassage: For viral vectors, the impact of cell-mediated immunity was more pronounced, and as depicted in Table 2 , almost always resulted in a reduction in the subsequent immune response. Presumably this is because viruses will induce neutralizing antibody on the first dose, and in subsequent doses this antibody will limit the number of transduced cells, therefore limiting the responses. This is particularly a problem with a common viral vector such as Ad, where a large proportion of the population will have immunological memory against common serotypes . As these authors conclude, it will be possible to utilize such vectors only", "Title: Pre-existing immunity against vaccine vectors – friend or foe?\nPassage: Only the study by Vijh et al. indicated that exposure to the empty vector may completely abrogate immune responses against the delivered antigens . However, these studies also indicate that downregulation of antigenspecific immune responses is highly dependent on dose and time. Leong et al. also demonstrated that the negative impact of vector-specific immune responses can also be countered by repeated immunization with the same vaccine and dose; this in effect leads to higher priming of naive T cells against the delivered antigen. Of course, such repeated vaccination may not be practicable in real-world situations.", "Title: Pre-existing immunity against vaccine vectors – friend or foe?\nPassage: expressing tetC, induced much lower anti-tetC responses than mice that had not been primed. This argues strongly that prior immunological immunity to the vector can seriously dampen subsequent antigen-specific humoral responses. Whether the same is true for cellular responses was not evaluated.", "Title: Vaccination With a Highly Attenuated Recombinant Vesicular Stomatitis Virus Vector Protects Against Challenge With a Lethal Dose of Ebola Virus\nPassage: to EBOVGP when part of the mucin-rich region was deleted, possibly as a result of altered proteosomal processing of EBOVGP or direct deletion of T-cell epitopes. After decay of the primary cell-mediated immune response, a second vaccine dose boosted ELISpot responses to levels seen after primary vaccination; however, there was still no detectable cell-mediated immune response elicited by vectors expressing EBOVGP from position 3 and 6, indicating the requirement for higher EBOVGP levels in infected cells to generate detectable EBOVGP-specific cell-mediated immune responses." ]

The variation pattern of influenza viruses was generally consistent. However, our study showed that RSV was more common in winter and spring, which was different from that reported in Saraya's study. Their study was conducted in adult patients with asthma, which might be responsible for the difference.

For the latter, it is specific to the studied period since the influenza Apdm09 virus reappeared in Réunion Island in October 2012 and was no longer circulating since late 2010. On the opposite, Parainfluenza 1,2 and 4 viruses were identified only in winter.
