PROBLEM: Paragraph: Experimental coronavirus retinopathy (ECOR) is a virally triggered model of retinal degeneration composed of both genetic and autoimmune components. Since TNF-a plays a role in immune-mediated processes we evaluated the levels of TNF-a/TNF-a receptors and the downstream signaling molecule nitric oxide (NO) during disease in both retinal degeneration susceptible BALB/c and degeneration resistant CD-1 mice. Following coronavirus injection, TNF-a mRNA was detected at higher levels within the retinas, and concentrations of TNF-a ( p < 0.005) and sTNFR1 ( p < 0.0005) proteins were increased within the sera of BALB/c but not CD-1 mice. While concentrations of sTNFR2 proteins were elevated in both BALB/c ( p < 0.00005) and CD-1 ( p < 0.005) mice compared to controls, concentrations were higher in BALB/c mice ( p < 0.0005). Gene expression of iNOS while initially high in BALB/c mice decreased during the acute phase of infection, while it increased in CD-1 mice. These trends are attributable to differences in monocyte TNFR2 release ( p < 0.0005) between the strains since sTNFR2 decreased ( p < 0.01) levels of NO production. These studies demonstrate that retinal degeneration following viral infection is associated with increased release of TNF-a/TNF receptors combined with a down-regulation of NO. Furthermore they suggest that these molecules are involved in alterations in immune response leading to autoimmune reactivity. Published by Elsevier B.V.

SOLUTION: False

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.

PROBLEM: Paragraph: The leader RNA of the 5′ untranslated region (UTR) of coronaviral genomes contains two stem-loop structures denoted SL1 and SL2. Herein, we show that SL1 is functionally and structurally bipartite. While the upper region of SL1 is required to be paired, we observe strong genetic selection against viruses that contain a deletion of A35, an extrahelical nucleotide that destabilizes SL1, in favor of genomes that contain a diverse panel of destabilizing second-site mutations, due to introduction of a noncanonical base pair near A35. Viruses containing destabilizing SL1-ΔA35 mutations also contain one of two specific mutations in the 3′ UTR. Thermal denaturation and imino proton solvent exchange experiments reveal that the lower half of SL1 is unstable and that second-site SL1-ΔA35 substitutions are characterized by one or more features of the wild-type SL1. We propose a "dynamic SL1" model, in which the base of SL1 has an optimized lability required to mediate a physical interaction between the 5′ UTR and the 3′ UTR that stimulates subgenomic RNA synthesis. Although not conserved at the nucleotide sequence level, these general structural characteristics of SL1 appear to be conserved in other coronaviral genomes.
