We now report that HSP60 in vitro differentially modulates the expression of Th1/Th2 transcription factors in human T cells: HSP60 down-regulates T-bet, NF-kappaB, and NFATp and up-regulates GATA-3, leading to decreased secretion of TNF-alpha and IFN-gamma and enhanced secretion of IL-10.

The IL-1beta and IFN-gamma-stimulated RIN cells showed increases in NF-kappaB binding activity and p65 subunit levels in nucleus, and IkappaB alpha degradation in cytosol compared to unstimulated cells.

PICin activated NF-kappaB and IRF-3 in a TLR3-independent manner, induced eukaryotic initiation factor 2 alpha phosphorylation, and triggered a massive production of interferon (IFN)-beta.

Use of a degradation-resistant NF-kappaB protein inhibitor (DeltaNIkappaBalpha), specifically expressed in beta-cells, significantly reduced IL-1beta+IFN-gamma-induced apoptosis.

Transient transfection experiments with the 1.5-kb rat promoter region and 5' deletants of it showed that a distal region extending up to -1002 bp, and containing a distal and a proximal nuclear factor-kappaB (NF-kappaB) binding site, a gamma-interferon activated site (GAS) and two adjacent IFN-stimulated response elements (ISRE), is required for IL-1beta induction and IFN-gamma potentiation of iNOS activation.

In these cells IFN-gamma potentiation is mostly mediated by GAS and ISRE, suggesting a role for the IFN-gamma-induced transcription factors Stat1alpha (which binds GAS) and IRF-1 (which binds ISRE), which may cooperate with NF-kappaB induced by IL-1beta for iNOS activation.

Inhibitors of NF-kappaB activation-the proteasome inhibitor MG-132 and the antioxidant pyrrolidine-dithiocarbamate (PDTC)-prevented poly IC + IFN-gamma-induced iNOS expression and nitric oxide production.

These results suggest that 1) NF-KB activation is required for dsRNA + IFN-gamma-induced iNOS expression, 2) PKR is not required for either dsRNA-induced NF-kappaB activation or dsRNA + IFN-y-induced iNOS expression by islets, and 3) PKR is not required for dsRNA + IFN-gamma-induced inhibition of glucose-stimulated insulin secretion by islets.
