Summary
Type I interferons (IFNs) play an important role in regulating immune responses to pathogens and tumors and are used therapeutically. This project will investigate a novel IFN signaling axis that we have recently characterized that is mediated via the low affinity IFN receptor, IFNAR1. This signaling axis occurs independently of the high affinity IFN receptor IFNAR2 and contributes to lethality in a model of septic shock.

Summary
Systemic lupus erythematosus is a disease where the immune system attacks normally healthy tissues. The spontaneous overproduction of signalling molecules called interferons in lupus plays an important role in the severity of the disease. We have found that two proteins, named Bcl6 and PLZF, are important in controlling the interferon response in lupus patients. We propose that identifying how these proteins act to control interferon will aid in developing new treatments for lupus.
New Insights Into Mechanisms That Coordinate Kinase Signalling And Molecular Motors In Mitosis: A Novel Role For The Protein Scaffold WD-repeat Protein 62 (WDR62).

Summary
Proteins perform all functions within a cell. Commonly, different proteins are assembled into large complexes to carry out processes, such as cell division, with significant implications for human health. Scaffold proteins facilitate the proper assembly of large complexes but are a poorly understood protein class. We will perform molecular analysis of a newly discovered scaffold, WDR62, to define how it drives cell division and reveal how this can be exploited to develop new anti-cancer drugs.
C-Jun N-terminal Kinase Regulation Of Microtubule Destabilizer, Stathmin - A Novel Cytoprotective Pathway

Summary
The loss of heart muscle cells during heart attack and heart failure worsens the severity of heart disease. We will study how to protect heart muscle cells by identifying the molecules involved in controlling survival responses. We will use this knowledge to prevent heart muscle cells from dying when exposed to a range of normally harmful conditions. Our study has the potential to prevent heart muscle cell loss, improve heart function and prevent muscle damage in heart disease.
Protein tyrosine phosphatases (PTPs) control cell communication networks referred to as cellular signaling. This proposal is focused on understanding the roles of PTPs in cellular signaling networks perturbed in human disease & delineating novel opportunities for therapeutic intervention
