PROBLEM: Paragraph: Ageing individuals are immunologically characterized by loss of immunological protection and responsiveness, and autoimmunity occurs with increased incidence. Here we review studies on specific age-related changes in B cell generation, activation, and maintenance as well as characteristics of B cell responses and antibody levels during ageing in relation to other cells and factors that are interwoven with B cell biological processes. In the elderly, fewer new B cells are generated, B cell responsiveness to antigens is impaired, and smaller and fewer germinal centers are formed within an immune response with participation of less potent T cells and follicular dendritic cells, leading to the production of reduced, often insufficient plasma cell numbers. Recall responses in the elderly appear to be limited by the cells' proliferative capacity. Hence, vaccine responsiveness is often insufficient and autoantibody production emerges in the elderly. In total, B cells appear to be less affected by age as compared with T cells. Recently, new concepts have been developed to counteract immunosenescence beyond active vaccination, comprising the generation of specific monoclonal antibodies for passive vaccination, immune rejuvenation by immunoablation followed by autologous stem cell transplantation, and modulation of lifestyle. 
 Title: Characteristics of B Cells and B Cell Responses in Aged Individuals

SOLUTION: True

PROBLEM: Paragraph: Pandemic 2009 H1N1 is normally susceptible to oseltamivir, but variants harboring the H275Y (CAC → TAC) mutation exhibit resistance. We describe the use of a combined reverse-transcription polymerase chain reaction (RT-PCR)/pyrosequencing approach to identify the H275 residue. A total of 223 specimens were tested with this method: 216 randomly selected clinical specimens positive for 2009 H1N1 and 7 cell-culture supernatants from the Centers for Disease Control and Prevention (CDC; 4 resistant, 3 susceptible 2009 H1N1 strains). The assay detected H275Y in 1 clinical respiratory sample (0.5%) and all 4 oseltamivir-resistant strains from the CDC; the remaining 215 clinical and 3 susceptible CDC specimens were wild-type. Sanger sequencing confirmed the results for 50 of 50 selected isolates. The RT-PCR/pyrosequencing method was highly specific, producing no amplicons or valid sequences from samples containing non-H1N1 viruses or bacteria. Our findings suggest that this method provides a rapid tool for H275Y detection, with high sensitivity and potential benefit for patient care. 
 Title: Reverse-transcription polymerase chain reaction/pyrosequencing to characterize neuraminidase H275 residue of influenza A 2009 H1N1 virus for rapid and specific detection of the viral oseltamivir resistance marker in a clinical laboratory

SOLUTION: False

PROBLEM: Paragraph: Porcine reproductive and respiratory syndrome virus (PRRSV) represents a significantly economical challenge to the swine industry worldwide. In this study, we investigated the importance of cellular and viral lipid rafts in PRRSV infection. First, we demonstrated that PRRSV glycoproteins, Gp3 and Gp4, were associated with lipid rafts during viral entry, and disruption of cellular lipid rafts inhibited PRRSV entry. We also showed the raft-location of CD163, which might contribute to the glycoproteins-raft association. Subsequently, raft disruption caused a significant reduction of viral RNA production. Moreover, Nsp9 was shown to be distributed in rafts, suggesting that rafts probably serve as a platform for PRRSV replication. Finally, we confirmed that disassembly of rafts on the virus envelope may affect the integrity of PRRSV particles and cause the leakage of viral proteins, which impaired PRRSV infectivity. These findings might provide insights on our understanding of the mechanism of PRRSV infection. 
 Title: Lipid rafts both in cellular membrane and viral envelope are critical for PRRSV efficient infection
