DNA fusion gene vaccination mobilizes effective anti-leukemic cytotoxic T lymphocytes from a tolerized repertoire
No full textThe majority of known human tumor-associated antigens derive from non-mutated self proteins. T cell tolerance, essential to prevent autoimmunity, must therefore be cautiously circumvented to generate cytotoxic T cell responses against these targets. Our strategy uses DNA fusion vaccines to activate high levels of peptide-specific CTL. Key foreign sequences from tetanus toxin activate tolerance-breaking CD4+ T cell help. Candidate MHC class Ibinding tumor peptide sequences are fused to the C terminus for optimal processing and presentation. To model performance against a leukemia-associated antigen in a tolerized setting, we constructed a fusion vaccine encoding an immunodominant CTL epitopederived from Friend murine leukemia virus gag protein (FMuLVgag) and vaccinated tolerant FMuLVgag-transgenic (gag-Tg) mice. Vaccination with the construct induced epitopespecificIFN-c-producing CD8+ T cells in normal and gag-Tg mice. The frequency and avidity of activated cells were reduced in gag-Tg mice, and no autoimmune injury resulted. However, these CD8+ T cells did exhibit gag-specific cytotoxicity in vitro and in vivo. Also, epitope-specific CTL killed FBL-3 leukemia cells expressing endogenous FMuLVgag antigen and protected against leukemia challenge in vivo. These results demonstrate a simple strategy to engage anti-microbial T cell help to activate epitope-specific polyclonal CD8+ T cell responses from a residual tolerized repertoire
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
Tetragonopterus denticulatus Silva, Melo, Oliveira & Benine 2013
No full textTetragonopterus denticulatus Silva, Melo, Oliveira & Benine, 2013 Fig. 11 Tetragonopterus denticulatus Silva, Melo, Oliveira & Benine, 2013: 1613 –1631 (original description; type locality: “Brazil, Goiás, Aragarças, Rio Araguaia, Amazon basin. Diagnosis. Tetragonopterus denticulatus is distinguished from all other congeners, except T. anostomus, T. juruena and T. kuluene, by the presence of 5–6 principal teeth on dentary (vs. 4 teeth) and by having thinner and sharper teeth (vs. larger and more robust teeth). It differs from T. anostomus by a terminal mouth (vs. subsuperior mouth); it differs from T. anostomus and T. kuluene by having two conspicuous humeral marks (vs. only one conspicuous humeral mark). Tetragonopterus denticulatus differs from T. anostomus and T. araguaiensis by having 13–14 rakers on the lower limb and 8–9 rakers on the upper limb of the first gill arch (vs. 17–20 and 10–12). Tetragonopterus denticulatus differs from T. juruena and T. kuluene by having 7 scale rows between lateral line and dorsal-fin origin (vs. 6). It further differs from T. argenteus by the presence of eight predorsal scales (vs. 11–17). Tetragonopterus denticulatus differs from T. carvalhoi by the presence of a rounded dark mark on caudal peduncle (vs. a lozenge-shaped mark on caudal peduncle). It differs from T. rarus and T. georgiae by having 3.5 scale rows between lateral line and pelvic-fin origin (vs. 4.5–5.5); it differs from T. rarus by the absence of dark longitudinal stripes on the trunk (vs. presence of stripes). Finally, T. denticulatus differs from T. ommatus by the presence of 3–4 maxillary teeth (vs. 7–8) and by having a mark centered on caudal peduncle (vs. mark limited to the posterior portion of caudal peduncle). Description. A detailed description of Tetragonopterus denticulatus was recently provided by Silva et al. (2013). Distribution. Tetragonopterus denticulatus was previously only known from the middle Araguaia basin in central Brazil. During the course of this study, specimens of T. denticulatus were also identified from the Rio Tocantins, extending its distribution range for this river system (Fig. 2 b). Material examined.
