DOI: 10.1139/m93-163Macrophages are critical effector cells in the inflammatory response. Classically activated macrophages initiate the innate immune response and direct the activity of the acquired immune response. Upon resolution of inflammation, macrophages convert to an anti-inflammatory phenotype called alternatively activated. Alternatively activated macrophages promote debris scavenging, tissue remodelling and wound healing. Intriguingly, macrophages can be manipulated to move back and forth between these two phenotypes. During inflammatory disorders, like inflammatory bowel disease, switching macrophages to an alternatively activated phenotype, could dampen down inflammation and reduce disease. We are currently assessing the macrophage phenotype present during inflammatory bowel disease and mechanisms that we could use to switch macrophages to an anti-inflammatory phenotype during disease.
L-arginine metabolism provides a key switch in macrophage phenotype. L-arginine can be metabolized by two pathways in macrophages. In classically activated macrophages during inflammation, the enzyme inducible nitric oxide synthase (iNOS) uses arginine to generate pro-inflammatory nitric oxide (NO). However, alternatively activated macrophages also express the enzyme arginase. Arginase metabolizes arginine leading to the production of polyamines, which promote cell growth, and proline, an essential component of collagen that can contribute to fibrosis. We are currently investigating the role of arginine metabolism by each of these pathways in inflammation and in fibrosis.
The src homology 2 domain-containing inositol 5'-phosphatase (SHIP) is a negative regulator of the phosphatidylinositol 3-kinase (PI3K) pathway. In vivo-differentiated SHIP deficient macrophages display a profoundly anergic phenotype and express phenotypic markers of alternative activation independent of canonical skewing by the Th2 cytokine, IL-4. SHIP protein levels are dramatically reduced when macrophages are skewed to an alternatively activate phenotype by IL-4 suggesting that increased PI3K activity may be required for canonical alternative activation of macrophages as well. We are currently characterizing the role of the PI3K pathway during canonical alternative activation of macrophages.

Every day, our researchers work towards breakthroughs to transform the lives of kids in BC and around the world. Learn about our latest innovations and advancements in child health.

A new approach to drug design can deliver medicine directly to the gut in mice at significantly lower doses than current inflammatory bowel disease treatments.

Congratulations to the BC Children’s Hospital Research Institute (BCCHR), Women’s Health Research Institute (WHRI), and Vancouver Coastal Health Research Institute (VCHRI) investigators and their teams who were awarded funding through the Canadian Institutes of Health Research (CIHR) Spring 2024 Project Grant competition. Several of our research community members received around $5 million in new research…

Dr. Bruce Vallance, a researcher at BC Children’s Hospital, is a joint principal investigator on a new national research training program that will support the next generation of trainees and early-career researchers specializing in digestive health. The team, led by Dr. Nicola Jones from SickKids Hospital, as well as Dr. Vallance and Dr. Derek McKay…
At BC Children’s, we are making discoveries that save lives and transform health care for children in our province and around the world. Our research portfolio includes basic, clinical, population, and public health research.
