  • Research Fields
    1.  CD38/cADPR/NAADP signaling pathway
    Second messengers, Cyclic ADP-ribose (cADPR) and Nicotinic acid adenine dinucleotide phosphate (NAADP), were both discovered by Prof. Lee Hon Cheung two decades ago. Both of them release calcium by acting on different channels on separate intracellular calcium stores. One of our goals is to identify their direct target proteins and elucidate the exact molecular mechanism of calcium mobilization.
    CD38 is a trans-membrane protein ubiquitously expressed in virtually all mammalian tissues, which is the only known enzyme catalyzing both cADPR and NAADP. Another major interest of our lab is to elucidate the regulatory mechanism of CD38 in the biogenesis process of cADPR and NAADP in cells.
    We are also interested in the physiological functions of this signaling pathway, especially in insulin secretion of pancreatic beta-cells.
    2.  Molecular pathology of multiple myeloma and CD38 antibody-based immunotherapy
    CD38 was found highly expressed on multiple myeloma cells, while much lower on normal cells, which makes it an ideal drug target. We aim to develop the diagnostic and therapeutic reagents against multiple myeloma or other CD38-related diseases based on the antibody.
    We are also interested in the mechanism how CD38 is involved in the pathological process of this disease.
