John Bermingham obtained a B.A. in Biology from Yale, and a Ph.D. from the University of Colorado, Boulder, where he studied the homeotic gene Antennapedia in Matthew Scott’s lab. Following a year of postdoctoral work on the Factor VIII coagulation gene in Jane Gitschier’s lab at UCSF, John moved to Geof Rosenfeld’s lab at UCSD, where he studied SR splicing factors, and generated mice that lack the transcription factor Oct-6(Pou3f1; SCIP; Tst1). He found that these mice display specific CNS defects and a delay in peripheral myelination. In his own laboratory at the McLaughlin Research Institute in Great Falls, MT, John obtained NIH funding to study Oct6 target genes in peripheral nerve.

Yo Sasaki was born and raised in Japan. He attended Tokyo University of Agriculture and Technology (B.S.) and Gunma University School of Medicine (Ph.D.) and decided to come to U.S. Yo is interested in the mechanism of axon degeneration. Axon degeneration is a common and early step of many neurological disorders and could be a useful therapeutic target for neurodegenerative diseases. Using injury-induced axon degeneration as a model, Yo and his colleagues discovered that overexpression of the NAD+ biosynthetic enzyme NMNAT1 can block axon degeneration. They identified other enzymes and substrates in NAD+ biosynthetic pathways that significantly delay axon degeneration. Based on these findings, Yo’s research is focused on the identification of axon survival signaling pathways that are linked to NAD+ metabolism.

Daniel Summers’ work revolves around how protein homeostasis pathways influence axon health and susceptibility to disease. His interest in this topic began as a graduate student in the lab of Doug Cyr at UNC-Chapel Hill, where he investigated how chaperone networks recognize unfolded proteins and regulate their disposal. As a joint postdoctoral fellow in the Milbrandt and DiAntonio labs, Daniel identified fundamental properties in the pro-degenerative factor SARM1 that promote the destruction of injured axons. He is merging his interests in protein homeostasis and axon health to characterize novel pathways that regulate the degradation of neuron survival factors in the axon. Daniel is currently supported by a grant from the Muscular Dystrophy Association with the hope of identifying new and potent avenues for therapeutic intervention in neurological disorders.
