The bovine CD8+ T-cell response to Theileria parva displays epitope immunodominance and oligoclonality por Connelley, Timothy K., MacHugh, Niall D., Graham, S., Taracha, E.A., Burrells, A., Ngugi, D., Morrison, W. Ivan

“…Analyses of large panels of T. parva-specific CD8+ T-cell clones from memory T-cells of immune animals homozygous for MHC haplotypes expressing either the A10 or A18 class I specificities, revealed that over 65% of the response was directed against a single immunodominant epitope (Tp1.1 for A18 and Tp2.2. for A10). TCRB-chain sequence analysis showed that for each immunodominant epitope the antigen-specific T-cells were polyclonal but dominated by large oligo-clonal expansions. …”

Value chain research and development: The quest for impact por Donovan, Jason, Stoian, Dietmar

“…We review the literature on MBDA to see how far this framing applies.We identify five cycles of approaches to market‐based development over the last 40 or more years: (1) non‐traditional agricultural exports; (2) small and medium enterprise development; (3) value chains with a globalization perspective; (4) value chains with an agri‐business perspective; and (5) value chain development.The shaping and sequencing of these cycles reflect researchers' tendency to analyse and criticize MBDA, while providing limited guidance on workable improvements; practitioners' reluctance to engage in critical reflection on their programmes; and an institutional and funding environment that encourages new approaches.Future MBDA will benefit from stronger engagement between researchers, practitioners, and funders. …”
