Asthma patients' immune systems respond differently with allergies
...ocytes produce cytokines that mediate and regulate immunity and inflammation to an immune stimulus. Because people with asthma and allergy share this common etiological pathway, they show different expressions of their disease with a wide variety of therapeutic responses.
