dc.description.abstract
As life expectancy increase, age-related disorders, such us neurodegenerative diseases (ND), have become more prevalent. Moreover, conventional treatments only attenuate some of the symptoms, but fail to arrest or delaycharacteristic neuronal proteotoxicity that characterizes them.. Thus, new challenges emerge to science in order to understand molecular basis of these disorders. Lately, the gut-brain axis has gain attention and a close relation between gut microorganism and ND has been proposed. In this context,T the aim of our work was to evaluate the relevance of the microbiota in the development and progression of proteotoxic-based disorders, assessing the impact of six non-pathogenic bacterial diets on life-history traits in C. elegans models of neurodegenerative disordersND (vs standard OP50). In a first approach, we found 2 bacteria, Escherichia coli K12 and E. coli HB101, able to improve locomotion in liquid media, in worm’s model of Parkinson disease (PD) at adult day 4, versus the traditional E. coli OP50. Moreover, an age-dependent locomotion improvement, between larva- L4 and adult day 4, was observed in solid media after feeding PD model´s worms with 4 different bacteria versus E. coli OP50. We also On the other hand, we obobserved an increase thatin the developmental timing of wild-type worms was increase when animals were grown in 4 bacteria versus E. coli OP50, but more interesting was the accelerated developmental rate selectively found in models of PD and Huntington disease feed with E. coli BL21 (DE3). We are currently evaluating aggregate numbers, lifespan and mitochondrial morphology among others. Our results allowed us to identify bacteria with the ability to drive physiological outcomes and improve health status of C. elegans models of neurodegenerative diseases.
