Secreted TNF-alpha mediated the enhancement of nuclear factor kappa B ( NF-kappa B ) and activator protein-1 ( AP-1 ) binding activity; in fact, the triggering of HLA-DR antigens in the presence of antihuman TNF-alpha -neutralizing antibodies did not upregulate NF-kappa B and AP-1 .
 HLA-DR antigens, TNF-alpha, nuclear factor kappa B, antihuman TNF-alpha -neutralizing antibodies, TNF-alpha, AP-1, AP-1, NF-kappa B, NF-kappa B
