title: B-, T-, and NK-cell lineage involvement in JAK2V617F-positive patients with idiopathic myelofibrosis.
abstract: An acquired JAK2 (V617F)mutation has been found in myeloid cells from most patients with chronic idiopathic myelofibrosis (IM), but whether it occurs in a common myelo-lymphoid, rather than a myeloid-restricted, progenitor cell is still debated. Using a sensitive ARMS assay for the quantitative assessment of JAK2 (V617F)cDNA, we detected the mutation in purified B-, T- and NK-cells from about half of 12 patients studied. These results indicate that involvement of lymphoid lineage in IM may be more frequent than previously supposed.
