Ghrelin Selectively Inhibits CaV3.3 Subtype of Low-Voltage-Gated Calcium Channels

The mechanisms by which ghrelin controls electrical activity in the hypothalamus are not fully understood. One unexplored target of ghrelin is CaV3, responsible for transient calcium currents (T-currents) that control neuronal firing. We investigated the effect of ghrelin on CaV3 subtypes and how this modulation impacts on neuronal activity. We performed whole-cell patch-clamp recordings in primary mouse hypothalamic cultures to explore the...
