Expression of MxA protein in blood lymphocytes of children receiving anticancer chemotherapy.

The aim of the study was to evaluate whether IFN-alpha/beta-inducible MxA protein expression in children receiving anticancer treatment can be used as an indicator for virus infections during the febrile episodes. Twenty-six children with mainly hematological malignancies entered the study. Children with laboratory-confirmed virus infections had clearly elevated MxA protein levels compared to their counterparts with bacterial or unknown etiology.
