The serious morbidity associated with Lyme borreliosis has focused
considerable effort on the development of a comprehensive vaccine for
protection against infection with Borrelia burgdorferi. Induction of borreliacidal antibody by vaccination or infection has
been shown to correlate with protection of humans and animals against
infection with the Lyme spirochete. In this report, we showed that high
levels of borreliacidal antibody (titer of 1,280) were produced in
vitro when T and B cells from hamsters 14 days after vaccination were
incubated with macrophages and B. burgdorferi. By contrast,
T and B cells from hamsters 7 or 21 days after vaccination failed to
initiate production of borreliacidal activity. Furthermore, the T cells
from hamsters 7 or 21 days after vaccination inhibited the in vitro
production of borreliacidal antibody when cocultured with T and B cells
obtained from hamsters 14 days after vaccination. When cell-free
supernatants from the suspensions of T and B cells from hamsters 14 days after vaccination were absorbed with recombinant OspA, they lost
nearly all borreliacidal activity. The removal of anti-OspA antibody
resulted in a decrease in borreliacidal titer from 1,280 to less than
4. These results demonstrate that T cells from vaccinated animals can
prevent a sustained production of protective borreliacidal antibody.
