- 요약Neurological pathologies provide a distinctively challenging region for new therapeutic targets due to extra physical protection, resident brain cell responses, and the fragility of the irreplaceable brain itself. Novel ways to approach neurological diseases include considering smaller molecules such as metabolites and their effects and origins, and exploring broader, more complex connections such as the gut-brain-microbiome axis. In Chapter 1, I discuss gut-brain-microbial pathways and how these unique connections may provide us with myriad therapeutic targets in disease, including glioblastoma and Alzheimer's disease (AD). Chapter 2 explores the enrichment of trimethylamine-N oxide (TMAO), a metaorganismal metabolite, in the olfactory bulb, indicating an impactful role in olfactory perception. The evidence supporting this observation comes from orthogonal studies using both pharmacological inhibition and genetic loss of function (LOF) models. These findings carry implications for potential dietary and sensory interventions associated with neural changes in AD. Chapter 3 includes investigation into a new mechanism of immune suppression in the tumor microenvironment (TME) via the small molecule metabolite spermidine (SPD). Metabolites such as SPD that are produced and secreted by tumor cells have an indirect effect on tumor growth by targeting immune cells in the TME. This novel connection provides a window into yet another manner glioblastoma cells are able to manipulate their surroundings, building hope for new therapeutic targets. Although not fully comprehensive, these studies highlight some unique mechanisms regarding how some metabolites function in brain cancer and how other metabolites are working through the microbe-host connection to influence neurological symptoms.
