STAT6-IP reduces the development of allergic-type lung inflammation and airway hyperresponsiveness

Dr. Elizabeth Fixman and Dr. Brian Ward (IDIGH Program at RI-MUHC) co-authored a study in the Journal of Leukocyte Biology demonstrating that STAT6-IP reduces the development of allergic-type lung inflammation and airway hyperresponsiveness in mice re-challenged with respiratory syncytial virus (RSV). (February 2017)

Scientists discover peptide that could reduce the incidence of RSV-related asthma

New research published in the Journal of Leukocyte Biology suggests that a peptide developed to inhibit a key regulator of asthma responses reduces development of inflammation and ‘twitchy’ airways in mice

For Details: Bharat T. Srinivasa, Katherine H. Restori, Jichuan Shan, Louis Cyr, Li Xing, Soojin Lee, Brian J. Ward, and Elizabeth D. Fixman. STAT6 inhibitory peptide given during RSV infection of neonatal mice reduces exacerbated airway responses upon adult reinfection. doi:10.1189/jlb.4A0215-062RR ; http://www.jleukbio.org/content/101/2/519.abstract

STAT6 inhibitory peptide

Educating the immune system with SAT6-IP

The STAT6 inhibitory peptide can educate the immune system away from developing an allergic response.

Dr. Elizabeth Fixman developed STAT6-IP, a chimeric inhibitory peptide with the ability to enter cells and disrupt activity of the STAT6 transcription factor. STAT6 has been show to inhibit aberrant Th2 responses in the airways of preclinical models of respiratory syncytial virus infection (Eur J Immunol 2014) and asthma (J Immunol 2007Clin Exp Allergy 2011Mucosal Immunol 2015). 

The latter publication by Dr. Christine McCusker received significant media attention.

This work was also selected for one of the top ten scientific breakthroughs of 2015 selected by Québec Science and Dr. Christine McCusker was nominated as the Feb 2016 Researcher of the Month by Canadians for Health Research.
