With funding from the Canadian Institutes for Health Research, the Arthritis Foundation and ¿ì²¥ÊÓƵ, Abdul-Sater and his research team are currently testing their findings in mice and hope the results will eventually translate to humans.<\/p>\n\n\n\n<p>\u201cWe are planning to use TRAF1 to develop new therapy for rheumatoid arthritis and other inflammatory diseases,\u201d Abdul-Sater says. \u201cI wouldn\u2019t wish rheumatoid arthritis on anyone; it is one of the most painful chronic diseases and it becomes progressively worse. For some sufferers, it can take hours just to get their joints moving each morning.\u201d<\/p>\n\n\n\n<p>Abdul-Sater calls TRAF1 \u201cthe Swiss army knife of proteins\u201d because it serves different functions in different immune cells. He discovered that TRAF1 can control or limit inflammation by preventing certain immune cells (macrophages) from producing too many cytokines that destroy the joints; on the other hand, previous research indicated that TRAF1 is also known to activate other immune cells (lymphocytes) and enhance their ability to produce antibodies or cytokines that damage the joints. The key is to find a way to stop TRAF1 from activating lymphocytes while preserving its ability to limit inflammation and cytokine production.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/yfile.news.yorku.ca\/wp-content\/uploads\/2022\/02\/York_Immunology_Abdul-Sater2-1024x683.jpg\" alt=\"Ali Abdul-Sater in his lab\" class=\"wp-image-299916\" width=\"768\" height=\"512\" srcset=\"https:\/\/www.yorku.ca\/yfile\/wp-content\/uploads\/sites\/889\/2022\/02\/York_Immunology_Abdul-Sater2-1024x683.jpg 1024w, https:\/\/www.yorku.ca\/yfile\/wp-content\/uploads\/sites\/889\/2022\/02\/York_Immunology_Abdul-Sater2-400x267.jpg 400w, https:\/\/www.yorku.ca\/yfile\/wp-content\/uploads\/sites\/889\/2022\/02\/York_Immunology_Abdul-Sater2.jpg 1200w\" sizes=\"auto, (max-width: 768px) 100vw, 768px\" \/><figcaption>Faculty of Health Professor Ali Abdul-Sater (foreground) in his lab<\/figcaption><\/figure><\/div>\n\n\n\n<p>It turns out that TRAF1 is a scaffold, or a platform, from which these signals are sent out. Abdul-Sater found that each of its functions used a different type of scaffold, so he was able to disrupt one function while leaving the other intact. In fact, he discovered a specific genetic mutation that does just that: it prevents immune cells from overproducing antibodies while suppressing its joint-destroying cytokine production, thus reducing inflammation and keeping the joint intact.<\/p>\n\n\n\n<p>Using the <a href=\"http:\/\/www.crisprtx.com\/\" data-type=\"URL\" data-id=\"http:\/\/www.crisprtx.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">CRISPR<\/a> genetic engineering tool that allows scientists to modify the genes of a living organism, Abdul-Sater and his team are currently creating this mutation in mice to determine whether they are protected from rheumatoid arthritis. If they are, he hopes to move forward toward using this discovery to create therapeutics for people currently living with rheumatoid arthritis.<\/p>\n\n\n\n<p>\u201cWe\u2019re not ready yet for interventions in humans,\u201d he says. \u201cOur next step would be to collaborate with medicinal chemists to develop a small molecule that can be taken as a drug and then, hopefully, move on to clinical trials. Drug formulation is a long process. We started from the ground up in finding a way to target this key protein.\u201d<\/p>\n\n\n\n<p>Abdul-Sater says research of this nature requires a real love for the work.<\/p>\n\n\n\n<p>\u201cTo stick it out, you have to have passion,\u201d he says. \u201cThere are lots of setbacks and long hours, but the reward is the joy of discovering something new and seeing it make a difference in the world.<\/p>\n\n\n\n<p>\u201cI have had excellent support from my department and my Faculty, and I feel lucky to get paid for doing something I love,\u201d he adds.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Faculty of Health Professor Ali Abdul-Sater\u2019s passion for understanding the body\u2019s immune response has led him to a discovery that
