[Interleukin 1 and hematopoiesis].

Abstract

Interleukin-1 mediates a broad spectrum of activities in the functional network of cytokines. In addition to its function as an inducer of the acute phase response IL-1 has many effects on hemopoiesis in normal and hematologically impaired organisms. This regulatory function is realized by its ability to stimulate the release of hematopoietic growth factors and by its recruiting property for cell cycles of different hemopoietic progenitors and stem cells. IL-1 acts synergistically with the colony-stimulating factors.
