Differential biochemical-inflammatory patterns in the astrocyte-neuron axis of the hippocampus and frontal cortex in Wistar rats with metabolic syndrome induced by high fat or carbohydrate diets.

Metabolic syndrome (MetS) is a public health problem and a risk of developing cardiometabolic and neurodegenerative diseases. The biochemical-inflammatory impairment in brain areas related to learning and memory has not been differentiated between MetS models. We aimed to compare the effect of the MetS generated by consuming high-fat (HFD) or -carbohydrate diets (HCD) on the hippocampus and frontal cortex, related to astrocyte-neuron metabolism and neuroinflammation origin.
