Abstract: Feeding is an intrinsic and important behavior regulated by complex molecular, cellular and
circuit-level mechanisms, one of which is the brain histaminergic network. In the past decades, many
studies have provided a foundation of knowledge about the relationship between feeding and histamine
receptors, which are deemed to have therapeutic potential but are not successful in treating feeding-
related diseases. Indeed, the histaminergic circuits underlying feeding are poorly understood and
characterized. This review describes current knowledge of histamine in feeding at the receptor level.
Further, we provide insight into putative histamine-involved feeding circuits based on the classic feeding
circuits. Understanding the histaminergic network in a circuit-specific way may be therapeutically
relevant for increasing the drug specificity and precise treatment in feeding-related diseases.
