Research Summary

Dr. Xiao-Ying Hua My major research interests include (1) investigation of role of selective protein kinases including protein kinase C (PKCα isoform) and mitogen-activated protein kinases (P38α, P38β) in spinal pain transmission by using intrathecal antisense approach; (2) study of activation and regulation of these protein kinases at spinal level during tissue injury/inflammation and development of morphine tolerance; and (3) participation of non-neuronal cells, such as microglia and astrocytes, in spinal hyperexcitability.
