CSF2 and infection: Examples of hematopoietic growth factors include erythropoietin (red blood cells enhancer), interleukin-11 (IL-11; platelets enhancer), erythrocyte stimulating agents (ESAs), thrombopoietin mimetics, granulocyte-macrophage colony-stimulating factor (GM-CSF), and granulocyte colony-stimulating factor (G-CSF) which improve leucocyte counts, leading to a reduced chance of infections.
