Studies have demonstrated that plant extracts possess various biological characteristics, including immunomodulatory activity. Heracleum persicum Desf. (Apiaceae), a medicinal plant native to Iran, was studied for its immunomodulatory activity. Immunomodulatory activity of different doses of an aqueous extract of H. persicum, was evaluated in female Swiss albino mice. Mice were treated with thr...
The in vivo functions of interleukin-3 (IL-3) were investigated by generating IL-3–deficient mice. Although hematopoiesis was unimpaired in homozygous mutant animals, contact hypersensitivity reactions were compromised. IL-3 was required for efficient priming of hapten-specific contact hypersensitivity responses, but was dispensable for T-cell– dependent sensitization to tumor cells. These find...
