IFN-alpha in vivo enhances tumor necrosis factor receptor levels on hairy cells.


Hairy cell leukemia (HCL) is a preplasma B cell neoplasia that is characterized by monocytopenia and responds to IFN-alpha therapy. We investigated the expression of receptors for TNF-alpha, a monocyte-derived cytokine, on the surface of hairy cells from seven HCL patients before and after treating them with IFN-alpha. Iodinated TNF-alpha binding… (More)
