CBD Reduced Brain Cell Death Signals in Rat Offspring Born to Obese Mothers

Adult offspring of rats fed an obesity-inducing diet showed elevated levels of the pro-apoptotic protein BAD in the prefrontal cortex, which CBD treatment (50 mg/kg for 3 weeks) mitigated. Female offspring also had elevated JNK (stress signaling), reduced by CBD. Male offspring showed reduced astrocyte and microglia populations, which CBD reversed.

Female Wistar rats were fed a cafeteria diet for 12 weeks before mating and through pregnancy and lactation. Adult offspring (postnatal day 70) received oral CBD (50 mg/kg) for 3 weeks. Researchers measured apoptosis proteins, TNF-alpha expression, and glial cell morphology in the prefrontal cortex.

Maternal obesity during pregnancy affects offspring brain development, and these effects persist into adulthood. This study suggests CBD could address some of the lasting brain changes, including inflammation and cell death signaling, that result from in utero obesity exposure.

With rising obesity rates among pregnant women worldwide, understanding how maternal obesity affects offspring brain health, and whether these effects can be reversed, has growing public health relevance.

Rat model with extreme obesity-inducing diet, CBD given in adulthood rather than preventively, only prefrontal cortex examined, short treatment duration (3 weeks), no behavioral outcomes measured in this study
