RESUMO
Using colony-forming assays, a number of previous studies established that interferon alpha (IFN-alpha) could cause bone marrow cell (BMC) suppression. In this study, the suppressive effect of IFN-alpha is however shown to be time-dependent, occurring only 7-8 days after transfer of BMC obtained from IFN-alpha-treated mice to growth factor-containing culture medium. In contrast, in the interval before suppression is observed, BMC obtained from IFN-alpha-treated mice initially proliferated more rapidly than BMC from placebo-treated mice. These findings suggest that IFN-alpha acts in vivo to prime the proliferative responses of BMC, a hitherto unexpected action which may have clinical relevance.
