Project Description

Inflammasomes are protein complexes that control inflammation in both infection and sterile injury. Aberrant inflammasome activation is a driver of many diseases including: cryopyrin-associated periodic syndromes, Alzheimer’s disease, Parkinson’s disease, gout, type 2 diabetes, atherosclerosis, non-alcoholic fatty liver disease, asthma, and silicosis. Targeted inflammasome blockade is thus a promising therapeutic strategy. Most of our understanding of inflammasome function is derived from mouse studies, thus how inflammasomes are regulated in humans is currently incompletely understood.

This project will examine inflammasome regulation, specifically in human cells, by using human induced pluripotent stem cells (hiSPCs) to generate macrophage cell models. Using CRISPR/Cas9-mediated gene editing of hiPSCs, we will interrogate how primate lineage-specific CARD-only proteins and Pyrin-only proteins regulate inflammasomes in human macrophages. It is increasingly appreciated that post-translational modifications (PTM) of inflammasome components are important regulatory checkpoints. We will examine how PTM of the inflammasome sensor NLRP3 control its activation, and dictate cellular responses including cell death and cytokine secretion. Characterising these regulatory mechanisms in a novel human cell system will enhance our understanding of the pathological role of inflammasomes and will generate novel targets for therapeutic intervention.

This project will be based at the internationally renowned Wellcome-Wolfson Institute for Experimental Medicine. The WWIEM is a hub for world-class researchers, experts in the fields of immunology, microbiology, molecular and cell biology, and clinical trials. In a highly collaborative environment, our collective focus is to understand why patients develop diseases and to make the discoveries which will lead to new therapies and improvements in their quality of life.
