小胶质细胞是脑内的免疫细胞,持续监测周围环境的变化。大约100多年前,研究者们就发现了小胶质细胞,但对于其来源,学术界一直存在争议。除了在胚胎发育的早期,迁徙进入发育中的神经外胚层的粒单核细胞群之外,在成年脑组织中,新迁入的骨髓细胞也是疾病的重要调节因子。因此,了解骨髓细胞从外周进入脑内及其分化为骨髓来源吞噬细胞的机制,有助于控制免疫细胞进入中枢神经系统,可能有利于疾病的控制。其中一个关键的问题是,骨髓来源的单核吞噬细胞是否具有和脑内源性免疫细胞相似的特征和作用。近年来,对小胶质细胞的生理和病理方面的研究较多,尤其是结合新基因定位技术,可以对细胞进行修饰、操控和跟踪分析,使得对小胶质细胞的生物学特性的认识有了较大的突破。本文即对相关研究进展综述如下。

The role of copper element has been an increasingly relevant topic in recent years in the fields of human and animal health, for both the study of new drugs and innovative food and feed supplements. This metal plays an important role in the central nervous system, where it is associated with glutamatergic signaling, and it is widely involved in inflammatory processes. Thus, diseases involving copper(Ⅱ) dyshomeostasis often have neurological symptoms, as exemplified by Alzheimer's and other diseases(such as Parkinson's and Wilson's diseases). Moreover, imbalanced copper ion concentrations have also been associated with diabetes and certain types of cancer, including glioma. In this paper, we propose a comprehensive overview of recent results that show the importance of these metal ions in several pathologies, mainly Alzheimer's disease, through the lens of the development and use of copper chelators as research compounds and potential therapeutics if included in multi-target hybrid drugs. Seeing how copper homeostasis is important for the well-being of animals as well as humans, we shortly describe the state of the art regarding the effects of copper and its chelators in agriculture, livestock rearing, and aquaculture, as ingredients for the formulation of feed supplements as well as to prevent the effects of pollution on animal productions.

Brain plasticity-A universal tool with many variations:The study of brain plasticity has been gaining interest since almost a century and has now reached a huge amount of information(>80,000 results in PubMed).Overall,different types of plasticity,including stem cell-driven genesis of new neurons(adult neurogenesis),cells in arrested maturation(dormant neurons),neuro-glial and synaptic plasticity,can coexist and contribute to grant plastic changes in the brain,from a cellular to system level(Benedetti and Couillard-Despres,2022;Bonfanti et al.,2023).
