A Missing Protein Stops White Blood Cells From Growing Up
Zebrafish and leukemia-cell experiments place progranulin beside JAK2-STAT3 signaling in the maturation of myeloid immune cells.
Summary
Zebrafish and leukemia-cell experiments place progranulin beside JAK2-STAT3 signaling in the maturation of myeloid immune cells.
Iowa State University researchers report that progranulin and an active JAK2-STAT3 pathway are both required for myeloid progenitor cells to mature into macrophages. In zebrafish, disrupting the pathway impaired development; in selected human leukemia cell lines with the relevant signaling active, adding progranulin pushed cells toward a more mature state. Those preclinical results expose a mechanism worth testing, not a leukemia treatment ready for patients, and the generic glassware image does not depict the work.
Why it matters
