外侧缰核(LHb)在抑郁症中是过度活跃的,因此增强对该结构的抑制是未来抗抑郁治疗的一个有趣的靶点。然而,在LHb内介导抑制信号传导的电路机制并不为人所知。我们通过研究LHb神经元表达小清蛋白(PV)或生长抑素(SOM),新皮层抑制性神经元的特定亚类的两个标志物来解决这个问题。在这里,我们发现,PV和SOM的生理上不同的子类表示。此外,我们描述了多个来源的抑制性输入LHb所产生的本地PV阳性神经元,从PV阳性神经元在丘脑背内侧核,并从SOM阳性神经元在腹侧苍白球。因此,这些发现为LHb内的抑制控制提供了新的见解,并强调该结构比以前认为的更加神经多样性。
The lateral habenula (LHb) is hyperactive in depression, and thus potentiating inhibition of this structure makes an interesting target for future antidepressant therapies. However, the circuit mechanisms mediating inhibitory signalling within the LHb are not well-known. We addressed this issue by studying LHb neurons expressing either parvalbumin (PV) or somatostatin (SOM), two markers of particular sub-classes of neocortical inhibitory neurons. Here, we find that both PV and SOM are expressed by physiologically distinct sub-classes. Furthermore, we describe multiple sources of inhibitory input to the LHb arising from both local PV-positive neurons, from PV-positive neurons in the medial dorsal thalamic nucleus, and from SOM-positive neurons in the ventral pallidum. These findings hence provide new insight into inhibitory control within the LHb, and highlight that this structure is more neuronally diverse than previously thought.
