Cyclic hematopoiesis in gray collie dogs can be cured by lithium treatment.
We examined the mechanism of lithium's effect by developing an assay for
the canine equivalent of GM-CSF (called GM-CSA). Phytohemagglutinin
(PHA)-stimulated canine blood mononuclear cells produce GM-CSA in a
dose-dependent manner; this GM-CSA stimulates more neutrophil-containing
colonies than does endotoxin-treated dog serum. Production of GM-CSA by
PHA-stimulated normal dog cells was not altered by lithium. However, cells
from gray collies during their neutrophilic period increased their GM-CSA
when lithium (2 mEq/L) was added to low doses of PHA, whereas neutropenic
gray collie cells did not. These data suggest that lithium could modulate
cyclic hematopoiesis by increasing intramedullary GM-CSA at the time when
marrow neutrophilic progenitor cells are at their nadir.
