最近一项关于自噬在果蝇大脑发育过程中两种不同神经元类型中的作用的研究揭示了调节突触形成的两种不同机制。在感光神经元中,突触原丝状足中的自噬体形成破坏了假定的突触接触,从而限制了不正确的突触伙伴关系。在背丛神经元中,自噬被主动抑制以保持成熟突触在轴突分支过程中的稳定。这些发现表明,在相同的发育时期,不同类型的神经元可能需要激活或抑制突触自噬,以确保适当的突触形成和大脑连接。
A recent characterization of the role of autophagy in two different neuron types during brain development in Drosophila revealed two different mechanisms to regulate synapse formation. In photoreceptor neurons, autophagosome formation in synaptogenic filopodia destabilizes presumptive synaptic contacts and thereby restricts incorrect synaptic partnerships. In dorsal cluster neurons, autophagy is actively suppressed to keep mature synapses stable during axonal branching. These findings indicate that different neuron types can require activation or suppression of synaptic autophagy during the same developmental period to ensure proper synapse formation and brain connectivity.
