1491-皮肤谷氨酸能神经元对衰老的调控研究
from 聊聊Sci
这项研究揭示了皮肤神经对衰老的关键调节作用。研究发现，皮肤中含有Nefh蛋白的谷氨酸能神经元会随着年龄增长而减少，进而导致胶原蛋白流失并加速成纤维细胞的衰老。通过Nefh-Cdk5-Vglut2分子轴，这些神经元维持着神经递质谷氨酸的正常释放。实验证明，补充谷氨酸能够通过皮肤成纤维细胞上的Slc1a3转运蛋白，有效抑制衰老表型并促进胶原蛋白再生。这一发现不仅阐明了神经系统调控皮肤健康的机制，还为治疗衰老相关皮肤疾病提供了谷氨酸补充或靶向Slc1a3等潜在新策略。References:Wang Z, Jin X, Wu Y, et al.

Deep Dream State
Neural Nets And Pretty Patterns
Deep Dream State is a full-cast dystopian sci-fi and desire horror audio drama by Neural Nets and Pretty Patterns. As the originating work of desire horror, it locates the uncanny inside wanting itself. While conventional horror positions you against a threat, desire horror implicates you in it. The horror emerges from recognition: the realization of why characters stay, and why surrender feels like relief. Since 2017, the show has used research in dream science, surveillance studies, behavioral economics, and advertising technology to examine systems of control through immersive sound design and full-cast performance.
