Abstract

Rhesus monkeys with persistent immediate-type cutaneous and respiratory responses (RR) to ascaris antigen (AA) were compared with rhesus monkeys with skin reactivity and no respiratory responses, and animals with no skin reactivity and no respiratory responses to inhaled antigen (NR). The RR group could not be distinguished from the nonresponding (NR) group by the cutaneous skin test titers, serum, or respiratory secretion IgE concentration. Leukocyte histamine (H) release due to anti-IgE was similar with peripheral blood leukocytes and bronchial lumen mast cells (MC) from RR and NR animals. The RR group of animals could be distinguished from the NR group by their degree of sensitivity to inhaled carbocholine and H release from respiratory MC exposed to AA. The RR group demonstrates consistent, persistent respiratory responses suitable for immunologic, pharmacologic, and physiologic studies. Finally, it was found that the IgE concentration in respiratory secretions of rhesus monkeys was comparatively higher than in serum, evidence for IgE as a secretory Ig in the respiratory tract of this species.
