SURF: Announcements of Opportunity
Below are Announcements of Opportunity posted by Caltech faculty and JPL technical staff for the SURF program. Additional AOs for the Amgen Scholars program can be found here.
Specific GROWTH projects being offerred for summer 2017 can be found here.
Students pursuing opportunities at JPL must be U.S. citizens or U.S. permanent residents.
Each AO indicates whether or not it is open to non-Caltech students. If an AO is NOT open to non-Caltech students, please DO NOT contact the mentor.
Announcements of Opportunity are posted as they are received. Please check back regularly for new AO submissions! Remember: This is just one way that you can go about identifying a suitable project and/or mentor.
Announcements for external summer programs are listed here.
|Project:||Gut-brain interactions in HD|
Senior Research Scientist, (BBE),
Huntington’s disease (HD) is a devastating genetically inherited neurodegenerative disorder caused by expansion of polyglutamine (polyQ) in the exon-1 of huntingtin (HTT). Although mutated HTT gene is expressed in all stages of development, it usually takes ~30-40 years for symptoms to develop. Moreover, the age of disease onset is highly variable in carriers with similar polyQ length. Inflammation is a candidate environmental factor, which may influence to the progression of HD symptoms. Pre-manifest HD subjects have activated microglia and elevated levels of pro-inflammatory cytokines including IL-1? and IL-6 and TNF-? several years before the onset of detectable motor symptoms. HD patients also display severe gastrointestinal complications. Moreover, HTT is expressed in the intestinal epithelium. However, influence of gut environment on the oligomerization of mutant HTT and its effect on the progression of HD symptoms remains unknown.
Recent studies highlight the importance of intestinal microbiota on brain development of neuropsychiatric disorders. We predict that microbial products may also affect the neurotoxicity of mutant HTT. Using a drosophila model of HD, we are testing the impact of bacterial byproducts, which are abundant in the intestinal lumen, on the polymerization and neurotoxicity of mutant HTT and behavior.
