Cytokine regulation of low-affinity IgE receptor (CD23) on monocytes from asthmatic subjects.

The regulation of CD23 expression (Fc epsilon RII) by cytokines on monocytes from normal subjects, asymptomatic and acute asthmatics was investigated. CD23 was weakly expressed on cells from controls, but was significantly enhanced in the two groups of asthmatics. The addition of IL-4 on monocytes induced an increase of CD23 expression in cells from… CONTINUE READING
