Regulation of immune mechanisms by pathogen cysteine proteases

Project Member(s): Donnelly, S.

Funding or Partner Organisation: National Health & Medical Research Council (NHMRC Project Grants)

Start year: 2008

Summary: To survive, parasites have evolved many strategies to control the human immune system. We have identified an enzyme secreted by parasites that can manipulate cells of the immune system, subsequently preventing the development of inflammatory responses. We will investigate the mechanism involved and determine whether this enzyme could be exploited for therapeutic purposes to switch off inflammation in autoimmune disease such as type-1 diabetes.
