Functional loss secondary to TNF-α expression. The quantitative assessment of electro-olfactogram (EOG) responses shows essentially no response after 6 weeks of dox-induced TNF-α expression even at the highest odorant concentrations. With concurrent prednisolone (pred), there is slight retention of responses but still markedly decreased when compared to control responses. Data reflects a minimum of 4 independent recordings. Error bars represent SEM.
