Description
Sulforaphane (SFN), an isothiocyanate, is part of an important group of naturally occurring small molecules with antiinflammatory properties. Even though the published reports are vague, most are best conceivable with an inhibition of T cell functions. We therefore analyzed the effect of SFN on T cell-mediated autoimmune disease. Feeding mice with SFN protected from severe experimental autoimmune encephalomyelitis (EAE). Disease amelioration was associated with reduced interleukin (IL)-17 and IFN-gamma expression in draining lymph nodes. In vitro, SFN treatment of T cells did not directly alter T cell cytokine secretion. In contrast, SFN treatment of dendritic cells (DC) inhibited TLR4-induced IL-12 and IL-23 production and the cytokine profile of T cells stimulated by SFN-treated DC. SFN suppressed TLR4-induced nuclear factor kappa B (NFB) activity, without affecting the degradation of its inhibitor (IB). Instead, SFN treatment of DC resulted in strong expression of the stress response protein heme oxygenase-1 (HO-1), which interacts with NFB p65 and inhibits its activity. Consistent with these findings, HO-1 bound to p65 and subsequently inhibited the p65 promoter activity within the IL23a and IL12b promoter region. Importantly, SFN suppressed Il23a and Il12b expression in vivo and silenced Th17/Th1 responses within the CNS . Our data show that SFN improves Th17/Th1-mediated autoimmune disease by inducing HO-1 and inhibiting p65-regulated IL-23 and IL-12 expression.

Description
Interleukin 2 (IL-2), a cytokine linked to human autoimmune diseases, limits IL-17 production. We show that deletion of Stat3 in T cells abrogates IL-17 production and attenuates autoimmunity associated with IL-2 deficiency. While STAT3 induces IL-17 and RORt and inhibits Foxp3, IL-2 inhibited IL-17 independently of Foxp3 and RORt. We found that STAT3 and STAT5 bound to multiple common sites across the Il17 genetic locus. The induction of STAT5 binding by IL-2 was associated with a reduction in STAT3 binding at these sites and the inhibition of associated active epigenetic marks. Titrating the relative activation of STAT3 and STAT5 modulated TH17 cell specification. Thus, the balance rather than the absolute magnitude of these signals determines the propensity of cells to make a key inflammatory cytokine.

Description
The Human T-cell Leukemia Virus (HTLV)-type-I non-structural protein p30 plays an important role in virus transmission and gene regulation. p30 has been documented to inhibit the export of certain viral mRNA transcripts from the nucleus to the cytoplasm. This nuclear retainment of RNA molecules essentially results in gene silencing, where protein products are not produced.
Publication Title
Genome wide analysis of human genes transcriptionally and post-transcriptionally regulated by the HTLV-I protein p30.

Description
To investigate changes in cardiac transcription profiles caused by off-pump cardiac surgery, we collected myocardial samples, prior and after grafting, from patients undergoing off-pump coronary revascularization surgery. The transcriptional profile of the mRNA in these samples was measured with gene array technology. Changes in transcriptional profiles can be correlated with the stress response of heart to off-pump surgery.
