Gulf War Illness (GWI) is characterized by a wide array of symptomology, which is possibly linked to the prophylactic treatment with pyridostigmine bromide (PB) against neurotoxins. It is now hypothesized that the pathological origin of this multi-symptom illness lies within the central nervous system and is caused by irregular activation of neuronal signaling pathways. To investigate this possibility, a proteomic-based approach was applied to characterize cellular responses of neuronal cells to PB exposure. Protein extracts from cultured neuroblastoma cells treated with 700nM PB for 10 days, as well as extracts from control cells were separated using two-dimensional gel electrophoresis. Twenty two differentially-expressed proteins were identified by MALDI-TOF mass spectrometry (MS). Ingenuity Pathways Analysis (IPA) software was then used to determine the biological functions and canonical pathways associated with the PB-responsive proteins.
