Four distinct CSFs were characterized[1]. Granulocyte colony-stimulating factor (G-CSF) acts on proliferation, functional stimulation and differentiation of progenitors of neutrophils. Granulocyte-macrophage colony-stimulating factor (GM-CSF) acts on proliferation, functional stimulation and differentiation of progenitors of neutrophils, monocytes and granulocytes[2]. Macrophage colony-stimulating factor (M-CSF) or lanimostin acts on proliferation, functional stimulation and differentiation of progenitors of monocytes and macrophages. multi-colony-stimulating factor also known as interleukin 3. Relevance Depletion of CSFs have therapeutic benefit in many inflammatory and autoimmune conditions[3]. G-CSF and GM-CSF are used to increase low white blood cell levels in cancer patients following chemotherapy and to release haematopoietic stem cells which replace bone marrow cells after anti-cancer treatments[4]. G-CSF is a neurotrophic factor and thus a candidate for the treatment of neurodegenerative conditions[5]. G-CSF and GN-CSF ar commercially available for clinical use[6]. Structural highlights The structure of the complex between M-CSF and its receptor shows that a dimer of M-CSF binds to 2 molecules of the receptor. There are two binding sites between the molecules designated site I and site II[7].
