The phosphorylation of BAG3 by CDK5 and its roles in astrocytes [PDF]
, 2016 细胞周期素依赖性蛋白激酶5（Cyclin-DependentKinase5，CDK5)是细胞周期蛋白依赖性丝氨酸/苏氨酸蛋白激酶家族中的一个成员，在神经系统的发育中发挥了至关重要的作用。CDK5的调节亚基P35、P39是神经系统特异性表达的蛋白，因此赋予了CDK5在神经系统中特异的激酶活性，使CDK5在调控神经递质传递，神经元凋亡等方面发挥了重要作用。对于CDK5的研究一直集中在对其新底物的发现和鉴定上，至今为止有40余个CDK5的底物被鉴定出来。作为脯氨酸依赖性蛋白激酶，CDK5可以特异磷酸化包含有 ...

Integrative Conservation, Volume 4, Issue 3, Page 476-490, September 2025.The leaf functional traits of angiosperms and gymnosperms in mountain ecosystems significantly influence phyllosphere fungal diversity. These traits are critical for understanding fungal stress resistance and elevational adaptation, which aids in predicting plant responses to climate change.

oleoylethanolamide improves spatial cognitive deficits through enhancing hippocampal neurogenesis after cerebral ischemia [PDF]
, 2015 我们先前的研究表明油酰乙醇胺（OEA）对急性脑缺血损伤具有神经保护作用。本研究的目的是探讨OEA对脑缺血引起的空间认知障碍，海马长时程增强作用（LTP）的抑制作用和海马神经发生的影响。结果表明：OEA30mg/kg显著改善大鼠脑缺血后空间认知功能障碍，促进海马长时程增强。另外，我们证实OEA通过促进海马神经发生改善脑缺血后的认知障碍。进一步的研究表明，OEA明显增加海马组织脑源性神经营养因子（BDNF）和过氧化物酶体增殖活化受体（PPARα）的表达 ...

Wildlife Letters, Volume 3, Issue 2, Page 73-83, June 2025.Blue sheep in Dhorpatan Hunting Reserve prefer alpine grasslands at 3800–4200 m on south‐facing slopes near water resources, favoring areas with low tree cover and dense ground cover, particularly rhododendrons, junipers, and Cyperaceae grasses. Their habitat significantly overlaps with livestock.

The role of LRP1 in microglia and neuroinflammation [PDF]
, 2016 神经炎症以中枢神经系统中小胶质细胞的激活、炎症因子以及趋化因子的大量表达为特征。小胶质细胞作为脑内最主要的免疫和吞噬细胞，在神经损伤以及包括阿尔兹海默症（Alzheimer’sdisease，AD）在内的神经退行性疾病中过度激活，同时起到神经保护或者毒性损伤功能。作为载脂蛋白E（apolipoproteinE，apoE）和β淀粉样蛋白（amyloid-β，Aβ）最主要的受体，低密度脂蛋白受体相关蛋白1（low-densitylipoproteinreceptor-relatedprotein1，LRP1）

Conservation Biology, Volume 39, Issue 3, June 2025.Abstract Successful long‐term conservation relies on strategic planning for pragmatic actions to mitigate threats. Prioritizing actions and areas to support conservation goals in the most cost‐effective scenario becomes crucial in resource‐limited environments. However, planning and management can be challenging in data‐limited contexts.
