Proteostasis and Immune Signalling in Cancer and Dementia
Research in a Nutshell
Proteostasis is a complex regulatory network which balances the cellular proteome by coordinating protein synthesis, folding, functional activity and degradation. Disruption of cellular proteostasis manifests in levels of proteotoxic stress that can compromise the immune system, initiate age related neurodegenerative conditions and predispose to cancer. We focus on defining the molecular and cellular mechanisms by which interferon regulated immune signalling and ubiquitin-mediated proteostatic mechanisms are integrated and coordinately regulated in order to protect cells and organs from aberrant protein:protein that re-purpose signal transduction pathways.
Our current focus is cancers of high unmet clinical need and dementia with synucleinopathies, for example:
- Two major obstacles in the treatment of oesophageal cancer (OAC) are metastasis and drug resistance. We are using tissue proteomics to identify novel OAC targets and dissecting pro- and anti-cancer interferon regulated proteins in order to develop novel biologics with anticancer activity. We are also exploiting interferon and proteostasis dependent immune-blockade pathways to define novel therapeutic approaches.
- Dementia with Lewy bodies (DLB) is a protein disease with a high unmet need for novel treatments and progression models. We are using iPSC derived neurons and animal models to study the role of ubiquitin pathways, proteostasis and interferon signalling in DLB.
