Summary
Peptides, with their high specificity and low toxicity profiles, are highly attractive alternatives to small molecule drugs. H2 relaxin, a peptide hormone, has a strong potential for treating fibrosis. However, the large size of H2 relaxin makes it difficult and expensive to manufacture. Once administered to patients, it is also quickly degraded. We have developed a small anti-fibrotic relaxin peptide, and propose to understand its mechanism of action and improve its therapeutic indices.
This project will substantially improve our understanding of the potential causes of vascular complications of pregnancy including preeclampsia, and provide a solid foundation to develop new clinical interventions for women who develop this disease during their pregnancy. It will also investigate if a peptide hormone, relaxin, could be an effective treatment to manage the health of women diagnosed with preeclampsia during their pregnancy and prevent delivery of severely premature infants.

Summary
Our laboratory recently discovered the brain 'transmitter' called 'relaxin-3', and are researching how it affects brain activity and animal physiology and behaviour. Findings suggest that relaxin-3 can modulate memory, responses to stress and other complex behaviours. Identifying the various actions of relaxin-3 in the brain could provide potential new treatments for conditions such as anxiety-depression, cognitive deficits (dementia) and schizophrenia.
