Cell-mediated immune mechanisms may play a role in the pathogenesis and prevention of pneumonia in cattle caused by Pasteurella haemolytica serotype A1. To determine the circumstances required to stimulate and identify cell-mediated immune responses, calves were vaccinated with a commercial P. haemolytica bacterin or a live commercial P. haemolytica vaccine, or were infected intratracheally wit...
Two murine models, C3H 38C13 B-cell lymphoma and AKR SL2 T-cell lymphoma were used to determine the efficacy of three different interferon preparations, recombinant human hybrid interferon-alpha A/D, recombinant murine interferon (rMIFN)-gamma, and natural MIFN-alpha/beta (greater than or equal to 85% beta), alone and in combination with tumor specific and nonspecific monoclonal antibody therap...
Interferon-alpha (IFN-alpha) and IFN-gamma regulate gene expression by tyrosine phosphorylation of several transcription factors that have the 91-kilodalton (p91) protein of interferon-stimulated gene factor-3 (ISGF-3) as a common component. Interferon-activated protein complexes bind enhancers present in the promoters of early response genes such as the high-affinity Fc gamma receptor gene (Fc...
