Abstract
Interferons are produced following neural damage as part of the inflammatory response and may thus affect neural stem cell function. We compared the effects of interferon-γ and interferon-β on the proliferation and differentiation of adult murine neural progenitors. Both interferons inhibited neurosphere proliferation due to cell cycle arrest in G1 but only interferon-γ induced neuronal differentiation. Both interferons induced differential phosphorylation of STAT proteins and a modest and late upregulation of the cell cycle regulator p27 but not several other likely cell cycle regulators. Thus in neural progenitor cells, anti-proliferative effects of interferons are not necessarily linked to differentiation.
