Choy Lab
Research in my laboratory is focused on understanding the mechanisms by which T cells and inflammatory responses become inappropriately activated in disease settings and how this causes organ damage.
Immune responses that cause organ transplant rejection and autoimmune diseases
Research in my laboratory is focused on understanding how the immune system is activated towards transplanted organs and how it causes resultant rejection. We have provided particular attention to how innate immune signals, such as cytokines secreted by innate immune cells and vascular cells, control the activation of T cells and how the gut microbiota influences immune responses that cause organ transplant rejection. Studies are also investigating cell engineering approaches that protect blood vessels in transplanted organs and how this can be applied to prevent rejection.
Nitric oxide signaling and production
Nitric oxide (NO) is a bioactive gas that controls many cell biological responses. Dysregulation of its production and/or bioactivity is involved in many diseases. My laboratory is interested in understanding how NO effects cell signaling and how its production is controlled by NO synthases. The role of NO and NO synthases in cell biology and immune responses is also being studied.
