Advances in detailed genetic and epigenetic characterizations along with an appreciation that subtypes associated with developmental origins, including brain location and patient age, have shifted glioma classification from the historical reliance on histopathological features to updated categories incorporating molecular signatures and spatiotemporal incidence. Within a subtype, individual gliomas show cellular heterogeneity, generally containing subpopulations resembling different types of normal glial and progenitor cells. In addition to tumor-autonomous mechanisms of aberrant growth regulation driven by genetic mutations and signaling between tumor cells, interactions with the tumor microenvironment, including neurons, astrocytes, oligodendrocyte precursor cells, and the immune microenvironment play important roles in driving glioma growth and influencing response to treatment. The emerging understanding of the complex contributions of normal brain to glioma growth represents new opportunities for therapeutic advances.","PeriodicalId":10494,"journal":{"name":"Cold Spring Harbor perspectives in biology","volume":"10 1","pages":""},"PeriodicalIF":7.2,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142253968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike every other organ in the body, the brain parenchyma lacks a traditional lymphatic system to drain fluids and central nervous system (CNS) antigens. It was historically assumed that all brain wastes were removed by endogenous processing, such as phagocytosis and autophagy, while excess fluids drained directly into the blood. However, the twin discoveries of the glial-lymphatic (glymphatic) system and meningeal lymphatics have transformed our understanding of brain waste clearance. The glymphatic system describes the movement of fluids through the subarachnoid space (SAS), the influx along periarterial spaces into the brain parenchyma, and the ultimate efflux back into the SAS along perivenous spaces where it comes into direct contact with the meningeal lymphatics. The dura mater of the meninges contains a bona fide lymphatic network that can drain CSF that has entered the dura. Together, these pathways provide insights into the clearance of molecules and fluids from the brain, and show that the CNS is physically connected to the adaptive immune system. Here, we outline the glymphatic and lymphatic systems, and describe the cellular components that are important to their function.","PeriodicalId":10494,"journal":{"name":"Cold Spring Harbor perspectives in biology","volume":"32 1","pages":""},"PeriodicalIF":7.2,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141933294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Skeletal muscles are composed of multiple fiber types whose structural and functional properties have only in part been characterized. Further progress in this field is mainly occurring along two directions: Multiomics approaches are providing a global picture of the molecular composition of muscle fibers up to the single fiber and single nucleus level. Signaling studies are identifying many transcription factors and pathways controlling fiber-type specification. These new data should now be integrated into a wider whole-body context by defining the matching between muscle fiber and motor neuron heterogeneity in the neuromuscular system, as well as the relevance of muscle fiber types in systemic homeostatic functions, including metabolism and thermogenesis.","PeriodicalId":10494,"journal":{"name":"Cold Spring Harbor perspectives in biology","volume":"74 1","pages":""},"PeriodicalIF":7.2,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141933436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are classified either as leukodystrophies (LDs), with primary glial abnormalities, or genetic leukoencephalopathies (gLEs), where other CNS cells are involved. As a group, these disorders are common, with an incidence of 1 in 7500 births. However, IWMDs often go undiagnosed or suffer delayed or misdiagnosis due to their heterogeneous presentation. Many of these disorders present with lethal secondary manifestations that can be prevented through early disease recognition, periodic surveillance, and preventative management. Emerging therapeutics, including gene therapy trials for metachromatic leukodystrophy (MLD) and adrenoleukodystrophy (ALD), suggest disease progression may be slowed or even prevented if treated early. Therapies for IWMDs that target glial cells or the peripheral immune system may provide novel insights for treating acquired disorders of white matter.","PeriodicalId":10494,"journal":{"name":"Cold Spring Harbor perspectives in biology","volume":"40 1","pages":""},"PeriodicalIF":7.2,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141933438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This process may be selective for specific cell components, as in the case of glycogen (glycophagy) or organelles, as with mitochondria (mitophagy). The autophagic flux is activated by fasting, and contributes with the proteasome to provide the organism with amino acids required for survival. Autophagy is also essential for the normal turnover of muscle proteins and organelles, as shown by the degenerative changes induced by genetic block of the autophagic mechanism, and in several myopathies. Autophagy is enhanced in muscle by exercise and impaired during aging, suggesting that aging-dependent muscle dysfunction could be delayed by boosting autophagy.","PeriodicalId":10494,"journal":{"name":"Cold Spring Harbor perspectives in biology","volume":"1 1","pages":""},"PeriodicalIF":7.2,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141933437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
