Elrod, KC, et al. Lactoferrin, a potent tryptase inhibitor, abolished late-phase airway responses in allergic sheep. American Journal of Respiratory Critical Care Medicine 156:375-381 (1997). Tryptase, a digestive enzyme, has been implicated in various aspects of asthma, including bronchoconstriction and airway hyperreactivity. Lactoferrin has been shown to inhibit tryptase activity, thus relieving the symptoms of asthma.
