Abstract (EN): A panel of monoclonal antibodies specific for CD27 ligand (CD70), CD30 ligand (CD153), CD134 ligand (OX40L), and CD137 ligand (4-1BBL) were screened in vivo for their ability to affect the control of Mycobacterium avium infection in C57B1/6 mice. Only the blocking of CD153 led to increased mycobacterial burdens. We then used CD30-deficient mice and found an increase in the proliferation of two strains of M. avium in these mice as compared with control animals. The increased mycobacterial growth was associated with decreased T cell expansion and reduced interferon-gamma (IFN-gamma) responses as a result of reduced polarization of the antigen-specific, IFN-gamma-producing T cells. At late times but not early in infection, the lymphoid cuff surrounding granulomas was depleted in the CD30-deficient animals. This report expands our knowledge about tumor necrosis factor superfamily members involved in the immune responses to mycobacterial infection by identifying CD30-CD153 interactions as required for optimal immune control of M. avium infection.
