If a person's cell have the antigen, the antibody should NOT be present in that person's serum. If an antibody to a blood group antigen is present in the serum of a person, his or her cells should lack that antigen. The antigens are on the cells and the antibodies are in the serum.

Abstract. Asthma is a complex disease of the lungs, which is characterized by airway inflammation and airway hyperresponsiveness (AHR). Alveolar macrophages (AMs), one of the prominent immune system cells found in the airways, have been implicated in the development and progression of asthma.AMs constitute a unique subset of pulmonary macrophages, which serve as a first line of defense against foreign invaders to the lung tissue.mong inflammatory cells, macrophages are the most abundant leukocytes found in alveoli, distal airspaces, and conducting airways, suggesting that they have an important role in providing protection against foreign pathogens at the interface of the external environment and the alveolar tissue.
