Autophagy plays a pivotal role in diverse biological processes,including the maintenance and differentiation of neural stem cells(NSCs).Interestingly,while complete deletion of Fip200 severely impairs NSC maintenance and differentiation,inhibiting canonical autophagy via deletion of core genes,such as Atg5,Atg16l1,and Atg7,or blockade of canonical interactions between FIP200 and ATG13(designated as FIP200-4A mutant or FIP200 KI)does not produce comparable detrimental *** highlights the likely critical involvement of the non-canonical functions of FIP200,the mechanisms of which have remained ***,utilizing genetic mouse models,we demonstrated that FIP200 mediates non-canonical autophagic degradation of p62/sequestome1,primarily via TAX1BP1 in *** deletion of Tax1bp1 in fip200hGFAP conditional knock-in(cKI)mice led to NSC deficiency,resembling the fip200hGFAP conditional knockout(cKO)mouse ***,reintroducing wild-type TAX1BP1 not only restored the maintenance of NSCs derived from tax1bp1-knockout fip200hGFAP cKI mice but also led to a marked reduction in p62 aggregate ***,a TAX1BP1 mutant incapable of binding to FIP200 or NBR1/p62 failed to achieve this ***,conditional deletion of Tax1bp1 in fip200hGFAP cKO mice exacerbated NSC deficiency and p62 aggregate accumulation compared to fip200hGFAP cKO ***,these findings illustrate the essential role of the FIP200-TAX1BP1 axis in mediating the non-canonical autophagic degradation of p62 aggregates towards NSC maintenance and function,presenting novel therapeutic targets for neurodegenerative diseases.

It has been widely recognized that hole transporting materials(HTMs)play a key role in the rapid progress of perovskite solar cells(PVSCs).However,common organic HTMs such as spiro-OMe TAD not only suffer from high synthetic costs,but also usually require the additional chemical doping process to improve their hole transport ability,which unfortunately induces the terrible stability ***,it is urgent to develop low-cost dopant-free HTMs for efficient and stable *** this work,we have successfully developed a new class of efficient dopant-free fluoranthene-based HTMs(TPF1–5)with quite low lab synthetic costs by combining donor-acceptor and branched structure *** detailed structure-property study revealed that tuning the twisted arms at different substitution sites would regulate the intermolecular interactions and film-forming ability,thereby significantly affecting the performance of the *** applying these HTMs in conventional PVSCs,the dopant-free TPF1-based devices not only achieved the best efficiency of 21.76%,which is comparable to that of the doped spiro-OMeTAD control devices,but also showed much better operational stability,which maintained over 87%of the initial efficiency under maximum power point tracking after 1038 h.

二维材料由于其丰富的材料组合和可调节的能带结构,为构建可重构的电子器件提供了绝佳的机会.本文使用PdSe_(2)/WS_(2)范德瓦尔斯平面结构造了具有高对称性p-n/n-p结模式的单栅极可重构二极管.栅极调制的带-带隧穿机制为反向整流提供了与正偏同等的电流,同时器件通过控制双极性的WS_(2)构成同质n-p结实现了高反向整流比.通过栅压调制,器件的p-n/n-p结模式能够形成高度对称,整流比具有1E−04到1E+04的无极调节能力,器件因此显示出高性能的可重构整流功能.我们也基于双模整流功能构建了逻辑反相器.本工作有助于拓展二维材料多功能器件的研究.
