Inhalation of Low-Level Formaldehyde Increases the Bcl-2/Bax Expression Ratio in the Hippocampus of Immunologically Sensitized Mice

Abstract

These results indicate that changes in the Bcl-2/Bax expression ratio, which occurs with low-level FA exposure and immunization and may follow enhancement of nerve growth factor production, exerts a protective effect against cell death by apoptosis.
