Neuroimmunology is an interdisciplinary branch of biomedical science that emerges from the intersection of studies on the nervous system and the immune system.The complex interplay between the two systems has long been recognized.Research efforts directed at the underlying functional interface and associated pathophysiology,however,have garnered attention only in recent decades.In this narrative review,we highlight significant advances in research on neuroimmune interplay and modulation.A particular focus is on early-and middle-career neuroimmunologists in China and their achievements in frontier areas of"neuroimmune interface","neuro-endocrine-immune network and modulation","neuroimmune interactions in diseases","meningeal lymphatic and glymphatic systems in health and disease",and"tools and methodologies in neuroimmunology research".Key scientific questions and future directions for potential breakthroughs in neuroimmunology research are proposed.

Endocytosis is a basic cellular process that describes a form of active transport across the plasma membrane into the cell.The endocytic pathway consists of distinct membrane compartments;internalized molecules are delivered to early endosomes,and some of them are recycled back to the surface,whereas other molecules are sent to late endosomes and lysosomes for degradation.However,little is known about how mitochondria are involved in the endocytic pathway.Here,we report that FM dyes, membrane-impermeant fluorescent lipid probes,can traffic to mitochondria directly from the plasma membrane by clathrinmediated endocytosis.FM dye entry into mitochondria uses microtubule-dependent active transport,but the mechanism is different from the classical endocytic pathway.Hence,this study reveals a previously unrealized lipid trafficking pathway from the plasma membrane to mitochondria.

Constructing inbred lines for self-incompatible species and species with long generation times is challenging,making the use of F1 outcross/segregating populations the main strategy for genetic studies of such species.However,there is a lack of dedicated algorithms/tools for rapid quantitative trait locus(QTL)mapping using the F1 populations.To this end,we have designed and developed an algorithm/tool called OcBSA specifically for QTL mapping of F1 populations.OcBSA transforms the four-haplotype inheritance problem from the two heterozygous diploid parents of the F1 population into the two-haplotype inheritance problem common in current genetic studies by removing the two haplotypes from the heterozygous parent that do not contribute to phenotype segregation in the F1 population.Testing of OcBSA on 1800 simulated F1 populations demonstrated its advantages over other currently available tools in terms of sensitivity and accuracy.In addition,the broad applicability of OcBSA was validated by QTL mapping using seven reported F1 populations of apple,pear,peach,citrus,grape,tea,and rice.We also used OcBSA to map the QTL for flower color in a newly constructed F1 population of potato generated in this study.The OcBSA mapping result was verified by the insertion or deletion markers to be consistent with a previously reported locus harboring the ANTHOCYANIN 2 gene,which regulates potato flower color.Taken together,these results highlight the power and broad utility of OcBSA for QTL mapping using F1 populations and thus a great potential for functional gene mining in outcrossing species.For ease of use,we have developed both Windows and Linux versions of OcBSA,which are freely available at:https://***/Bioinformaticslab/OcBSA.

As a result of evolution,our body has evolved into a sophisticated system in which various tissues and organs cooperate in a highly orchestrated manner.Few tissues or organs operate in isolation.The brain serves as the command center of our body and is relatively isolated from the peripheral system due to the presence of the blood-brain barrier(BBB).This barrier prevents direct and extensive interaction between blood cells,plasma molecules,and brain cells,contributing to the longstanding perception of the brain as an“immune-privileged”area.Consequently,neuroscientists and immunologists historically conducted separate research with minimal overlap between these two disciplines.However,this perspective has undergone reconsideration over the past few decades.

Trans-neuronal viral tracing is becoming one of the most important methods for mapping neuronal circuit connections,but an anterograde trans-synaptic tracer compatible with functional assays is still lacking.Adeno-associated virus（AAV）is replication-defective,and its production of offspring needs the help of adenovirus（AV）[1]or herpesvirus co-infection[2].The replication deficiency,non-pathogenicity,easy manipulability,

Anxiolytic Effect of Increased NREM Sleep after Acute Social Defeat Stress in Mice

细胞—生命的基础——中国细胞生物学学会2013年全国学...

作者： Shumin Duan Zhejiang University School of Medicine

Glial cells can release signal molecules that mediate intercellular communication.In particular,ATP release from astrocytes is required for Ca wave propagation among astrocytes and for feedback modulation of synaptic functions.We found that lysosomes in astrocytes contain abundant ATP and their partial exocytosis resulted in a low-level ATP release,whereas full exocytosis led to the release of a larger amount of ATP,together with lysosomal enzymes.Repetitive neuronal activity induces release

Social defeat stress(SDS)plays a major role in the pathogenesis of psychiatric disorders like anxiety and depression.Sleep is generally considered to involve recovery of the brain from prior experience during wakefulness and is altered after acute SDS.However,the effect of acute SDS on sleep/wake behavior in mice varies between studies.In addition,whether sleep changes in response to stress contribute to anxiety is not well established.Here,we first investigated the effects of acute SDS on sleep/wake states in the active period in mice.Our results showed that total sleep time(time in rapid eyemovement[REM]and non-REM[NREM]sleep)increased in the active period after acute SDS.NREM sleep increased mainly during the first 3 h after SDS,while REM sleep increased at a later time.Then,we demonstrated that the increased NREM sleep had an anxiolytic benefit in acute SDS.Mice deprived of sleep for 1 h or 3 h after acute SDS remained in a highly anxious state,while in mice with ad libitum sleep the anxiety rapidly faded away.Altogether,our findings suggest an anxiolytic effect of NREM sleep,and indicate a potential therapeutic strategy for anxiety.

tAstrocytes are the largest glial population in the mammalian brain.However,we have a minimal understanding of astrocyte development,especially fate specification in different regions of the brain.Through lineage tracing of the progenitors of the third ventricle(3V)wall via in-utero electroporation in the embryonic mouse brain,we show the fate specification and migration pattern of astrocytes derived from radial glia along the 3V wall.Unexpectedly,radial glia located in different regions along the 3V wall of the diencephalon produce distinct cell types:radial glia in the upper region produce astrocytes and those in the lower region produce neurons in the diencephalon.With genetic fate mapping analysis,we reveal that the first population of astrocytes appears along the zona incerta in the diencephalon.Astrogenesis occurs at an early time point in the dorsal region relative to that in the ventral region of the developing diencephalon.With transcriptomic analysis of the region-specific 3V wall and lateral ventricle(LV)wall,we identified cohorts of differentially-expressed genes in the dorsal 3V wall compared to the ventral 3V wall and LV wall that may regulate astrogenesis in the dorsal diencephalon.Together,these results demonstrate that the generation of astrocytes shows a spatiotemporal pattern in the developing mouse diencephalon.
