Project Goal:
The goal of this project is to identify molecules that prevent apoptosis in pancreatic beta cells that is induced by a combination of cytokines, namely Interferon-gamma, Interleukin 1-beta and tumor necrosis factor-alpha.

Keywords:
Diabetes, apoptosis, cytokine, beta cells, insulin

Biological Relevance:
Type 1 diabetes is caused by autoimmune destruction of insulin-producing beta cells in the pancreas. Human beta-cell apoptosis in this process involves a complex set of signaling cascades initiated by interleukin-1b (IL-1b), interferon-g (IFN-g), and tumor necrosis factor-a (TNF-a). IL-1b and TNF-a induce NFkB expression, while downstream activation of gene expression is thought to occur through nitric oxide (NO) signaling, which both increases the endoplasmic reticulum stress-response pathway and decreases beta-cell function. These effects of cytokines are beta cell-specific, and we aim to find small-molecule suppressors that would have little to no effect on other cell types in the pancreas.

Small molecules that increase beta-cell survival in the presence of cytokines could be of potential clinical benefit to early-stage type 1 diabetic patients. A number of studies have described small molecules with protective effects in the presence of cytokines; most of these were discovered because of their antioxidant or anti-inflammatory effects. Further, small-molecule inhibition of histone deacetylases (HDAC) with suberoylanilide hydroxamic acid (SAHA) or trichostatin A (TSA) can prevent cytokine-induced beta-cell death, presumably by decreasing NFkB transactivation. Therefore, multiple mechanisms may serve to protect beta cells from cytokine-induced apoptosis.
