The effect of overexpressing SNX8 on the phenotype of Alzheimer’s mice [PDF]
, 2015 阿尔茨海默病（Alzheimerdisease，AD）是最为常见的神经退行性疾病。神经元胞外Aβ（Amyloidβ，Aβ）聚集形成的淀粉样斑是AD的一个重要的病理特征，而Aβ是由淀粉样前体蛋白APP（AmyloidPrecursorProtein，APP）经β-分泌酶（β-secretase）和γ-分泌酶（γ-secretase）依次切割后生成的（即淀粉样蛋白途径），而APP的另一条剪切途径是α-分泌酶（α-secretase）和γ-分泌酶依次对其进行剪切，释放有神经保护作用的sAPPα ...

People and Nature, Volume 8, Issue 2, Page 270-282, February 2026.Abstract Chinese consumer demand for ivory threatens vulnerable African elephant populations, despite long‐standing efforts to combat the illegal wildlife trade. Behavioural science approaches have been proposed to address these systemic behaviours. However, their robust use remains uncommon in demand management interventions.

Effects of landscape fragmentation on floodplain fishes as revealed by species–habitat networks
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract How species interact with habitat patches is influenced primarily by habitat configuration (e.g., connectivity) and species’ functional traits. As levels of fragmentation increase, identifying the intricate connections between these components is crucial for biodiversity conservation.

Genetic origins and climate‐induced erosion in economically important Asian walnuts
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little

Mechanistic study of TREM2 mutations in increasing the risk of neurodegenerative diseases [PDF]
, 2016 2型髓系细胞触发受体（Triggeringreceptorexpressedonmyeliodcells2，TREM2）是中枢神经系统（centralnervoussystem，CNS）中主要表达于小胶质细胞表面并参与机体固有免疫的一种受体蛋白，与其接头蛋白酪氨酸激酶结合蛋白（DNAXactivatingproteinof12kDa，DAP12）形成TREM2/DAP12复合物，从而调节小胶质细胞中的炎症反应和吞噬功能。TREM2属于Ⅰ型跨膜蛋白，其胞外段经过蛋白酶切割后产生可溶形式TREM2 ...

SWEET1‐mediated glucose transport is crucial for energy availability in Arabidopsis
New Phytologist, Volume 249, Issue 4, Page 1816-1830, February 2026.Summary The stress‐responsive hormone abscisic acid (ABA) is known for its inhibitory effects on various physiological processes, including seed germination, often resulting in energy deprivation. Interestingly, ABA‐induced germination inhibition can be alleviated by exogenous glucose (Glc), mimicking a functional interplay between ABA and sugar ...
