Immunoprecipitation/mass spectrometry analyses of Aβ release into conditioned medium. Neurons were incubated in the absence or presence of 200 nM testosterone for 10 days. Levels of Aβx-40 and Aβx-42 species measured in the presence of testosterone (Lower) were significantly lower than control (Upper) levels in each of three experiments, including the one illustrated here.
