  • What is a cytokine?
    A cytokine is a soluble protein that facilitates communication between cells and regulates immune responses.
  • What effects do paracrine signals have?
    Paracrine signals affect nearby cells by binding to their receptors and inducing changes such as movement, differentiation, or cell death.
  • What is a function of cytokines related to inflammation?
    Promoting inflammation.
  • What role do chemokines play in the immune response?
    Chemokines guide immune cells to infection sites through chemotaxis, facilitating the elimination of microbes.
  • How do colony stimulating factors affect leukocytes?
    Colony stimulating factors stimulate the growth and differentiation of immature leukocytes in the bone marrow.
  • What is the primary function of interferons?
    Interferons provide antiviral defenses to neighboring cells by inducing protective responses.
  • What is the role of tumor necrosis factors (TNF) in the immune system?
    TNF initiates inflammation and can induce apoptosis in infected cells.
  • How do interleukins facilitate communication in the immune system?
    Interleukins serve as communication molecules between leukocytes, promoting various immune responses.
  • What is the function of interleukin-2 (IL-2)?
    Interleukin-2 promotes rapid T cell proliferation, enhancing the immune response.
