Abstract

This review demonstrates that basophils reflect skin and lung mast cell reactivity and show characteristic changes in mediator release associated with clinical disease. Although the numbers of IgE molecules and IgE receptors on basophils have been enumerated, these have, in most instances, little influence on the release of histamine after challenge. There is, rather, a parameter of 'releasability' that may be a major variable in allergic disease states. Basophils contain and release histamine, the eosinophil chemotactic factor of anaphylaxis (ECF-A), a slowly reacting substance of anaphylaxis (SRS-A), and a kallikrein. The release process is controlled by hormone-basophil receptor interactions that determine the cyclic AMP level; plasma and tissue adenosine levels appear prominent in this control. Histamine feeds back to negatively modulate basophil and mast cell release through a specific histamine 2-receptor; it also inhibits lymphocyte and neutrophil function. Like neutrophils, basophils contain beta-glucuronidase while neutrophils contain SRS-A and a low-molecular-weight ECF. The stimuli for primary basophil and neutrophil release are, however, quite different, although phagocytic stimuli, which fail to cause basophil mediator release, potentiate the IgE response. It is concluded that basophils play a significant in vivo role in inflammation by acting as an interface between foreign antigens, the serum cascade systems, and other inflammatory cells.
