Taken together, these data demonstrate the pivotal role of Th17 lymphocytes in brain pathology and olfactory processing deficits after recurrent GAS infections in our mouse model. Our intranasal inoculation model supports the conclusion that post-infectious BGE is autoimmune in nature, despite the absence of behavioral symptoms in this model. Using multiple mouse models of post-infectious BGE may allow us to study distinct facets of disease pathogenesis. Finally, this work underscores the ability of T cells to incite neuroinflammation, provides a useful clinical diagnostic test in olfactory functional assessments, and lends support to T cell immunotherapy strategies in patients with post-infectious BGEs.
