Significant reductions in interleukin-37 and tryptophan were found in CRPS subjects, along with positive correlations between kynurenine/tryptophan ratio and TNF-α levels with kinesiophobia, tetrahydrobiopterin levels with McGill pain score, sRAGE, and xanthurenic acid and neopterin levels with depression, anxiety and stress scores. Using machine learning, we identified a set of binary variables, including IL-37 and GM-CSF, capable of distinguishing controls from established CRPS subjects. These results suggest possible involvement of various inflammatory markers in CRPS pathogenesis. Although the role of inflammation in epilepsy pathogenesis has been extensively investigated, the inflammasome complex, a key component of neuroinflammation, has been understudied in epilepsy patients. To better understand the involvement of this system in epilepsy, levels of inflammasome complex components (NLRP1, NLRP3, CASP1, ASC), end-products of inflammasome complex activity [IL-1β, IL-18, nitric oxide synthase (NOS) isoforms] and other inflammatory factors (NFκB, IL-6, TNF-α) were measured in peripheral blood of patients with focal epilepsy of unknown cause (FEoUC) (n=47), mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS) (n=35) and healthy controls using real time qPCR and/or ELISA. Inflammasome complex associated factors were either downregulated or unchanged in epilepsy patients. Likewise, flow cytometry studies failed to show an increase in ratios of NLRP3-expressing CD3+ and CD14+ peripheral blood mononuclear cells (PBMC) in epileptic patients. Anti-neuronal antibody positiveively, the IL-6-NFκB signaling pathway, appears to be activated in focal epilepsy, suggesting that factors of this pathway might be targeted
