Research Interests

Our immune system needs to be in a perfect balance for keeping us healthy, and this balance is maintained by a group of proteins named “cytokines”. Cytokines are signaling molecules used to communicate between various immune cell types, which are critical not only for their development, but also for ensuring proper immune responses are triggered when required (see Wan and Leonard, Encyclopedia of Immunobiology 2016). An active, responsive immune system is certainly important as patients with immunodeficiency often develop cancers, and are frequently subjected to infections (see Wan et al., PNAS 2015). However, excessive immune responses are also not desirable, as they would lead to immunopathology. Examples are autoimmune diseases caused by over-reactive immune cells that recognize and attack our own body (see Wan et al., Immunity 2013; Wan et al., J Immunol 2016).

Multiple sclerosis (MS) is an autoimmune disease that the over-reactive immune cells attack the central nervous system (CNS). This attack causes severe inflammation, leading to irreversible damages of the CNS. Current therapeutic strategies aimed to reduce the frequency of relapses (attacks) but are unable to cure the disease. Improper production of certain cytokines, such as GM-CSF, IL-17 and IL-23 significantly correlates with the pathogenesis of MS but exactly how they do it, particularly what immune cell types and signaling pathways involved are not well defined. The overall goal of my research is to 1) identify cytokines and underlying mechanisms that govern the pathogenesis of multiple sclerosis, and neuroinflammation in general, using pre-clinical animal models; 2) explore novel inhibitors that target signaling molecules responsible for triggering neuroinflammation by high throughput screening; and 3) decipher gene expression profiles and functional abnormality of immune cells isolated from MS patients.

These studies will not only improve our understanding on how improper control of immune cell activation leads to neuroinflammation, but also have potential clinical impacts on MS treatments.
