The correlation between virus induced NF-kappa B DNA binding activity and interferon gene expression was examined in the myelomonoblastic PLB-985 cell line. Previous studies have shown that chronic HIV-1 infection of PLB-985 cells (PLB-IIIB) leads to the selection of cells with a more differentiated monocytic phenotype and with constitutive NF-kappa B DNA-binding activity. In this report we demonstrate that the kinetics of HIV-1 and Sendai virus infection of PLB-985 cells directly correlates with induction of NF-kappa B DNA binding activity. Based on UV cross-linking and immunoprecipitation analysis, p50, the strong transcriptional activator p65 and c-Rel represent the major constituents of this NF-kappa B DNA-binding activity. We also demonstrate an alteration in the kinetics of type I IFN gene transcription following secondary Sendai virus infection of PLB-IIIB cells compared to PLB-985. The results of our studies suggest that HIV infected individuals may respond differently to secondary viral or bacterial infections by augmenting the synthesis of NF-kappa B regulated immune response modifiers, which could alter the onset or progression of AIDS.

D011518	Proto-Oncogene Proteins	Products of proto-oncogenes. Normally they do not have oncogenic or transforming properties, but are involved in the regulation or differentiation of cell growth. They often have protein kinase activity.

D002478	Cells, Cultured	Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others.	Cultured Cells,Cell, Cultured,Cultured Cell
D004247	DNA	A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
