Abstract:
:The T-helper response to the measles virus nucleoprotein (NP) has been studied in mice. The T-cell proliferative response was measured in lymphocytes from mice immunized with either a vaccinia measles-NP recombinant virus or a mouse neuro-adapted measles virus. A T-cell response was obtained with lymphocytes from H2d or H2k mice when stimulated with either measles virus or the NP expressed in bacteria. The response was CD4+ specific. The T-helper epitopes were mapped using truncated NP peptides. The major epitopes in both H2d and H2k mice were determined to be between amino acids 67-98. A further T-cell epitope (between amino acids 457-525) was identified when H2d mice were immunized with measles virus. Studies to quantitate the precursor cells for these epitopes confirmed that the region 67-98 of NP was immunodominant in both haplotypes immunized with the vaccinia-NP recombinant virus, whereas an additional major epitope was observed in the measles virus-infected H2d mice. The primary structure of the epitopes determined here are compared to predicted T-cell epitope motifs.
