1 We demonstrated that activation of nuclear factor kappaB (NF-kappaB) is essential in zymosan A (a source of 1-->3-beta-glucans)-induced TNF-alpha production in macrophages (RAW264.7 cells). Zymosan nuclear factor of kappa light polypeptide gene enhancer in B cells 1, p105 Mus musculus
2 Inhibition of NF-kappaB activation led to a dramatic reduction in both TNF-alpha promoter activity and TNF-alpha protein production in the response to zymosan A. Zymosan nuclear factor of kappa light polypeptide gene enhancer in B cells 1, p105 Mus musculus
3 Mutation of a major NF-kappaB binding site (kappa3) in the gene promoter resulted in a significant decrease in the induction of the gene promoter by zymosan A, while mutation of Egr or CRE sites failed to inhibit the response to zymosan. Zymosan nuclear factor of kappa light polypeptide gene enhancer in B cells 1, p105 Mus musculus
4 Mutation of a major NF-kappaB binding site (kappa3) in the gene promoter resulted in a significant decrease in the induction of the gene promoter by zymosan A, while mutation of Egr or CRE sites failed to inhibit the response to zymosan. Zymosan nuclear factor of kappa light polypeptide gene enhancer in B cells 1, p105 Mus musculus
