Explanation:
CSFs (colony stimulating factors) are glycoproteins that activate intracelluar pathways and promote proliferation of hemopoietic stem cell to form immune cells (white blood cells).
CSFs are released in response to infection and interacts with blood stem cells to produce new immune cells. These resulting new immune cells create an army of cells to fight against the infection and provide immunity.
