Research Interests
Cell death plays pivotal roles in many biological processes, such as development and pathogenesis of many degenerative diseases. Programmed necrosis, also known as necroptosis, is morphologically marked by the swelling of cellular organelles, rapid loss of cell membrane integrity and release of cellular contents. Necrosis functions during pathogen infection, drug-induced cell injuries and trauma-induced tissue damages. The necrotic death of injured cells help to isolate and remove the pathogens and induce immune response to viral infection. In addition, necrosis is implicated in regulating chemical-induced cell injuries, such as cerulein-induced pancreatitis. Furthermore, excessive necrotic cell death is associated with ischemia reperfusion induced damage in brain and cardiac tissues as well as in patients with neurodegenerative disorders. On the other hand, dysfunction of apoptosis underlies tumor genesis, proliferation and resistance to chemotherapy. As the alternative cell death, necrosis induced by various therapeutic stimuli will provide us a new direction in the treatment of cancer.
Programmed necrosis is a kinase initiated death pathway. In the case of TNFR1 activation, the most studied model of necrosis to date, the necrotic cell death depends on the kinase activity of RIP1 and RIP3. Mixed lineage kinase domain-like protein (MLKL) is a critical substrate of RIP3 in necrosis pathway. The formation of necrosome by the interaction of RIP1, RIP3, MLKL and other molecules would mediate the signaling downstream of death cytokines (such as TNF), finally causing cell death and inflammation.
Our research focuses on the molecular mechanism of necrosis signaling, and the relevance to human diseases. We sincerely welcome those who are interested in cell death to join us!
