About
Sheena Lee is a molecular neuroscientist whose research centers on the molecular mechanisms underlying cerebellar development and neurodegeneration, with a particular focus on insulin-like growth factor 1 (IGF-1) signaling. Her landmark study, "AF4 Is a Critical Regulator of the IGF-1 Signaling Pathway during Purkinje Cell Development" (2009, 27 citations), established AF4 as a key transcriptional regulator linking IGF-1 signaling to Purkinje cell survival and maturation. This work provided critical insight into how disruptions in this pathway contribute to cerebellar ataxia—a finding that bridges fundamental developmental biology with potential therapeutic strategies for neurodegenerative disease. Lee’s research has been instrumental in identifying IGF-1 signaling dysregulation as a common pathological cascade across multiple mouse models and human ataxia patients, highlighting a convergent mechanism that may be targeted for intervention. Her contributions have shaped our understanding of how specific molecular pathways govern neuronal health and vulnerability, offering a foundation for future therapies aimed at halting or reversing cerebellar degeneration.
