Topic: Maternal obesity

Maternal obesity predisposes offspring to metabolic diseases. Insulin resistance and adiposity secondary to maternal calorie-rich high-fat diet consumption are considered key contributors to such developmental programming. Here, we show that non-nutritive sensory components of high-fat diet (HFD), beyond its hypercaloric, obesogenic effects, are sufficient to alter metabolic health in the offspring. To dissociate the caloric and sensory components of HFD, we fed dams a diet isonutritional to a normal chow diet but enriched with fat-related odors mimicking the sensory signature of a commonly us

Maternal obesity during pregnancy is a significant global health concern, impacting the metabolic, cardiovascular, and neurological health of the offspring, the latter being a research topic that has become of great interest. Our study investigates their effects on cognition, focusing on the hippocampus, a region vulnerable to prenatal insults. While maternal high-fat diet (mHFD) has been linked to cognitive deficits and hippocampal changes, its impact on synaptic transmission remains unexplored.Our focus was to understand how this adverse prenatal environment influences memory processes and w
