140 12721805 Temperature sensitive mutations in the genes encoding the NS1, NS2A, NS3, and NS5 nonstructural proteins of dengue virus type 4 restrict replication in the brains of mice.
141 12922097 Cytotoxic T lymphocytes (CTLs) were induced by plasmids encoding capsid (C) or nonstructural proteins, NS1, NS2A, NS2B, NS3 or NS5.
142 12958248 Here, we describe microsphere immunoassays that detect antibodies to nonstructural proteins 3 and 5 (NS3 and NS5).
143 14696328 These results yeilded a consensus composition of NS1, NS2A, NS3, NS4A, and NS5 strongly associated with the dsRNA template.
144 14696328 Assembly of the RC during translation in cis and the relationships, particularly those of NS1 and NS5 among the components, were deduced from an extensive set of complementation experiments in trans involving mutations/deletions in all the nonstructural proteins and use of KUN or alphahavirus replicons as helpers.
145 15027699 They are defined the genotype concepts, subtype and quasispecies, and their implications in different such aspects as: 1) pathogenicity (in the severity of the infectious process, in the extrahepatic manifestations and in the appearance of the hepatocarcinoma); 2) in the biggest or smaller sensibility in the diagnostic techniques; 3) in the resistance to the treatment with interferon (well through the road NS3 or NS5, so much through the changes in PKR or the mutations in ISDR), and 4) in the epidemiology (changes of geographical variability, use of that variability like epidemic marker and obtaining difficulty of vaccines).
146 15187120 The NS3-DC-peptide fusion protein was efficiently presented to CD4+ and CD8+ T cells derived from hepatitis C virus-positive blood cells, inducing their activation and proliferation.
147 15187120 In chimeric NOD-SCID mice transplanted with human cells, DC-targeted NS3 primed naive CD4+ and CD8+ T cells for potent NS3-specific proliferation and cytokine secretion.
148 15246602 A single injection of this non-replicating vector into BALB/c mice resulted in a strong induction of NS3-specific, IFN-gamma secreting T-lymphocytes as measured by direct ex vivo ELISpot assay.
149 15368525 Interferon-gamma (IFN gamma)-producing CD8+ T cells have been shown to play a key role in the control or eradication of hepatitis C virus (HCV) infections.
150 15368525 This peptide was capable to recall in vitro HCV-specific IFN gamma and IL-10-producing T cells from peripheral blood mononuclear cells (PBMC) of chronically infected patients.
151 15368525 These data increase the pool of NS3-specific CD8+ T cell epitopes available to analyze HCV associated immunity and could contribute to the design and evaluation of candidate vaccines.
152 15890119 Eleven strains isolated from hospitalized patients from 1994 to 1999 in Saudi Arabia were sequenced in the envelope, NS3, and NS5 genes.
153 16148104 Of 22 subjects who spontaneously controlled HCV viremia, all recognized at least one of a group of six epitopes situated within the nonstructural (NS) proteins NS3, NS4, and NS5, each of which was detected by >30% of subjects, but most subjects recognized additional, more heterogeneous specificities.

155 16317673 There was a statistically significant inverse correlation between peak viral loads and envelope glycoprotein 2 (E2)-specific antibody responses at the time of challenge.
156 16317673 Interestingly, one vaccinee that had sterilizing immunity against slightly heterologous virus generated the highest level of E2-specific total and neutralizing antibody responses as well as strong NS3/NS5-specific T-cell proliferative responses.
157 16336932 NS3 was effective at inducing in vitro responses, quantified by lymphoproliferation, IFN-gamma ELISPOT, flow cytometric detection of activated T cell subsets, and cytotoxic T cell assays.
158 16336932 In addition to the IFN-gamma responses, induction of both CD4+ T helper cell and CD8+ cytotoxic T cells (CTL) were discernible--activation of the latter was confirmed in a virus-specific cytolytic assay.
159 16361412 NS3 protein was efficiently transduced into DCs and treatment of DCs with CpG ODN induced phenotypic maturation and specifically increased the expression of CD40.

164 16415020 The E5-104 mutant possessed five amino acid substitutions in the structural protein E and one change in each of the nonstructural proteins NS3 and NS5.
165 16481078 To develop a vaccine against hepatitis C virus, we synthesized four long peptides from nonstructural proteins NS3, NS4 and NS5B containing HLA-class I and class II epitopes mainly inducing responses in natural infection.

176 16847121 The addition of adjuvants or a delivery system to the HCV polyprotein enhanced serum antibody and T-cell proliferative responses, as well as IFN-gamma responses, by CD4+ T cells.
177 16847121 The antibody responses were mainly against the NS3 and NS5 components of the polyprotein and relatively poor responses were elicited against NS4 and the core components.
178 16859951 Broad immune responses, in particular specific for the NS3 protein and mediated by both CD8+ and CD4+T lymphocytes, are thought to play a critical role in the control of hepatitis C virus (HCV) infection.
179 16859951 In this study, we searched for novel HLA-B*0702 NS3 restricted epitopes following an optimized NS3NS4 immunization protocol in transgenic mice expressing HLA-B*0702 molecule.
180 16859951 The relevance of these epitopes to humans was demonstrated, as both were able in vitro to recall specific IFN-gamma and IL10-producing cells from peripheral blood mononuclear cells of HCV infected patients.
181 16859951 Such epitopes enlarge the pool of NS3-specific CD8+T cell epitopes available to perform immunomonitoring of HCV infection and to develop vaccines.

190 16889980 All three proteins were able to induce high levels of specific antibodies and, in the case of the NS3 and HVR1 tetramer, also to mount vigorous cell-proliferating responses.
191 17172057 Due to B-cell HVR1 mimotopes mimicking the antigenicity of natural HVR1 epitopes and some T-cell epitopes from the consensus sequence of HCV genes conserving among the different HCV genotypes, we synthesized an minigene of HCV-derived multi-epitope peptide antigen (CMEP), which contains 9 B-cell HVR1 mimotopes in E2, 2 conserved CTL epitopes in C, 1 conserved CTL epitope in NS3 and 1 conserved Th epitope in NS3.
192 17240490 Adoptive transfer of NS3/4A mRNA-transfected DCs resulted in migration to regional lymph nodes, strong cellular immune responses and protection from challenge with vaccinia virus expressing NS3/NS4/NS5 in mice.
193 17451465 Mice were immunized with recombinant NS3 protein (rNS3) and poly (I:C) emulsified in Montanide ISA 720 (M720).
194 17451465 Cytokine production was assayed by enzyme-linked immunospot assay, and CD4(+) IFN-gamma(+) T helper (Th) cells or CD8(+) IFN-gamma(+) cytotoxic T lymphocytes were detected by flow cytometry.
195 17451465 The cytokine profiles showed that this formulation induced a Th1-biased immune response with several-fold more interferon-gamma (IFN-gamma)-producing cells than interleukin-4-producing cells.
196 17451465 The frequency of IFN-gamma-producing CD4(+) and CD8(+) cells induced by rNS3 in poly (I:C) and M720 was significantly higher than that induced by rNS3, rNS3 in M720, or rNS3 in poly (I:C), and was comparable to that induced by rNS3 in CpG-ODN with M720.

211 20053820 A global vaccine based on conserved proteins across genotypes may be feasible, as a five-antigen mosaic cocktail provided 90, 77 and 70% coverage of the Core, NS3 and NS4 proteins, respectively; protein coverage diminished with increased protein variability, dropping to 38% for NS2.

219 20870946 Using a phage-displayed random peptide library, we identified a 15-mer synthetic peptide, P60, able to bind to forkhead/winged helix transcription factor 3 (FOXP3), a factor required for development and function of Treg.
220 20870946 P60 enters the cells, inhibits FOXP3 nuclear translocation, and reduces its ability to suppress the transcription factors NF-κB and NFAT.
221 20870946 P60 administration to newborn mice induced a lymphoproliferative autoimmune syndrome resembling the reported pathology in scurfy mice lacking functional Foxp3.
222 20870946 Similarly, P60 improved the antiviral efficacy of a recombinant adenovirus expressing NS3 protein from hepatitis C virus.

254 22573867 H-2-deficient mice transgenic for either A2, A24, B7, DR2, DR3, or DR4 HLA alleles were immunized with overlapping peptides of the WNV proteome, and peptide-specific T-cell activation was measured by gamma interferon (IFN-γ) enzyme-linked immunosorbent spot (ELISpot) assays.
255 22573867 Notably, only 51 were WNV specific, and the remaining 86, chiefly of E, NS3, and NS5, shared an identity of nine or more consecutive amino acids with sequences of 64 other flaviviruses, including several major human pathogens.
