Abstract

To determine whether inflammation and apoptosis are involved in the pathogenesis of autism, we examined cytokines, Bcl2 expression and cathepsin D protease activity in the lymphoblasts of autistic subjects and age-matched controls. We found increased expression levels of pro-inflammatory cytokines TNF-α and IL-6, but decreased Bcl2 expression in lymphoblasts of autistic subjects. We also found that cathepsin D mRNA and protein expression were significantly increased in autistic lymphoblasts.

CONCLUSION:

Our findings suggest that inflammation and apoptosis may play a significant role in the pathogenesis of autism, and cathepsin D may participate in the regulation of cytokine-induced inflammation and apoptosis in autistic lymphoblasts.
