Example sentences for: immunogens

How can you use “immunogens” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Upon introduction into a host's cells, these sub-genomic fragments should replicate intracellularly and support prolonged expression of dengue and heterologous immunogens without producing the deleted dengue structural proteins and without forming infectious virions.

  • Experiments are now in progress to determine the feasibility of long term expression of other HIV-1 immunogens, including gag and tat.

  • Antigen-specific T cells encounter antigen presented by dendritic cells that migrate to the paracortical regions of draining lymph nodes after initial antigen contact [ 1 ] . Only dendritic cells have the capacity to induce activation in resting peripheral T cells [ 2 3 ] . Once activated, differentiated T helper cells contact antigen-specific B cells and provide signals for B cell differentiation via CD154-CD40 interactions, as well as by the production of cytokines [ 4 5 6 ] . Consistent with this general understanding of the induction of antibody responses to protein immunogens, good antibody responses to synthetic peptide-epitope constructs have been shown to depend on the presence, orientation, and multiplicity of the T cell epitope in the construct [ 7 8 9 10 11 ] . As a confirmation of this finding with synthetic epitope constructs, most protein immunogens studied to date contain multiple T cell epitopes, for example [ 12 13 ] .

  • Therapeutic vaccinations administered after treated acute HIV-1 infection and before cessation of therapy have given disappointing results thus far [9], but the availability of new and more potent immunogens requires reassessment of this approach.

  • To serve as effective vaccines, it is preferable, if not necessary, that expression systems be capable of expressing immunogens for longer than a couple of days.
