Potentiation of interferon-mediated inhibition of Chlamydia infection by interleukin-1 in human macrophage cultures.


One mechanism by which interferons (IFNs) can inhibit chlamydial infection is by the induction of the enzyme indoleamine 2,3-dioxygenase (IDO), which restricts the availability of tryptophan, which is required for chlamydial growth. Other immunomodulating agents, including interleukin-1 (IL-1), can interact synergistically with IFNs, resulting in increased… (More)
