Understanding The Role Of Lipids Derived From The Gut Microbes In A Mouse Model Of Obesity-Induced Peripheral Pain, Raiza Rafael-Bonomo Hardy

Dissertations

The increase in obesity has been accompanied by a rise in the prevalence of painful peripheral neuropathy. Recently, studies have suggested a role for gut microbiome in the development of some peripheral pain, including chemotherapy- induced pain and fibromyalgia. In the present dissertation, we showed that modulation of gut microbiome in obese mice alleviated neuropathic indices, concurrent with changes in immune cell profile within the peripheral nerve system. We demonstrated that fecal transplantation from lean to obese mice decreased obesity-induced pain and restored nerve density in the skin. These improvements were accompanied by changes in peripheral nerve system gene expression, …
