We wish to define the association of asthma, vitamin A serum levels and vitamin A receptor number and responsiveness on circulating mononuclear cells. Asthma is a complex, heterogenous and often debilitating and potentially deadly disease. The causes for asthma are many, with susceptibility and resistance to treatment is poorly understood.
