Susceptibility of mice to mousepox offers promise of smallpox protection
...response. Conversely, they found IL-2 in the lymph node
but not in the spleen. The reasons why this happens are still unclear, said Karupiah, but understanding them may help researchers figure out what constitutes an effective immune response. The mousepox model has proven a useful tool for studying small...
