The aim of the research is to find new therapeutic targets which may be specific to certain organs or disease processes, in order to develop more effective and selective treatments ofchronic inflammatory disease in humans.Read moreRead less
Activated Protein C Suppresses The Abnormal Immune Response In Rheumatoid Arthritis
Funder

Funding Amount
$380,558.00
Summary
This project will determine whether activated protein C (APC) reduces the severity of rheumatoid arthritis (RA) by altering the abnormal response of a type of white blood cells known as the T cells. Experiments will utilise T cells isolated from patients with RA, normal controls and an animal model of RA, to examine a newly discovered immune pathway now thought to play a major role in causing RA. The results will help clarify whether and how APC prevents joint destruction in RA
Regulation Of Extrinsic Death Pathways In Neutrophils

Summary
During infection, the lifespan of neutrophils normally increases despite an abundance of neutrophil death signals in inflamed tissues. Altered lifespan of neutrophils has been reported in diseases associated with influenza, Streptococcus, RSV and cytomegalovirus infection. Our research has discovered a relationship between the two dominant death pathways in neutrophils, indicating that alterations in one death pathway protect the neutrophil from death signals from the second death pathway.
A type of white blood cell, the macrophage, is a key player in determining the chronicity of inflammatory conditions such as rheumatoid arthritis, atherosclerosis, psoriasis, nephritis, multiple sclerosis etc. Two particular proteins can control macrophage development and functions, both under normal conditions and during inflammation. The project aims to understand this control. More rational ways to suppress inflammation due to aberrant macrophage function should result.
