In Vitro Effects of Chemotactic Factors on Eosinophil Fc and Complement Receptor Expression

Eosinophils possess membrane receptors for the Fc portions of IgG and IgE and also for fragments of the complement component C3, i.e. C3b (CR1) and C3bi (CR3). A number of mediators of inflammation are known to be able to upregulate eosinophil function in vitro, including increased expression of membrane receptors.
