    Dr. Ho's research interests are focused on investigating the role of inflammation in the pathogenesis of osteoarthritis. The therapeutic potential and mechanisms of several anti-inflammatory drugs in osteoarthritis were also examined both in vitro and in vivo. In addition, following her post-doctor studies, Dr. Ho also actively participate several inflammation-related studies such as dengue virus infection in human dendritic cells and the examination of the immunomodulatory effects and mechanisms of Chinese anti-inflammatory drugs. These ongoing studies cover many different fields involving molecular, cellular and animal aspects.


    Dr. Ho published more than 23 original SCI publications in the field of microbiology and immunology. She started her research career in the field of gerontology since she joined the division of Gerontology of NHRI in 2003. Their research group already published a paper which suggest that vitamin A may protect OA patients from pro-inflammatory cytokine-mediated damage of chondrocytes and their supporting matrixes via blocking p38 kinase activity and JNK-AP1 signaling (Ho et al., Biochemical Pharmacology 2005 15;70:200-8). Currently, they actively participate in studying the chondroprotective effect of several potential immunomodulatory drugs, testing both in vitro and in vivo models. The influence of collagen glycation on the the chondrocyte activity and their possible role in leading to the occurrence of osteoarthritis is another research project they are interested in . In addition, Dr. Hos lab. set up research cooperation with other disciplines including pharmacologist and clinical physician to span the breadth and depth of their research.
