This has traditionally been studied in the context of specific transmembrane receptors, particularly integrin adhesion receptors, which link extracellular adhesive molecules to the actin cytoskeleton. However, leukocytes and other cells can also migrate using integrin-independent strategies both in vivo and in vitro, though the cellular and environmental requirements for this mode are not fully understood. In seminal recent work, Reversat et al.1 develop a range of innovative 2D and 3D engineered microdevices and probe the biophysical mechanisms underlying T lymphocytes and dendritic cells in conditions of limited substrate adhesion. They identify a physical principle of mechano-coupling between retrograde actin flow and irregular extracellular confinement, which allows the cell to generate mechanical resistance and move in the absence of receptor-mediated adhesion. Through the combined use of experiments and theoretical modeling, this work resolves a long-standing question in cell biology and establishes mechanical interaction with an irregular-shaped 3D environment which may be relevant to cell migration in a range of tissue contexts.","PeriodicalId":73016,"journal":{"name":"Faculty reviews","volume":"11 ","pages":"18"},"PeriodicalIF":0.0,"publicationDate":"2022-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9354731/pdf/facrev-11-18.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10607783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Recent advances in connexin gap junction biology","authors":"P. Lampe, D. Laird","doi":"10.12703/r/11-14","DOIUrl":"https://doi.org/10.12703/r/11-14","url":null,"abstract":"Connexins are assembled into dodecamer intercellular channels, a collection of which is termed a gap junction, and their canonical function allowing direct exchange of ions and metabolites has been unequivocally established. When initially assembled into undocked cell surface connexin hemichannels, healthy cells may also engage in cell signaling via a regulated small-molecule release. Recent advances in the field have led to an expanded view of the functional roles of intercellular channels and hemichannels in both physiology and pathology. As more of the 21-member human connexin family is intensely interrogated, mounting evidence points to the biological uniqueness of each member, and no longer can we confidently refer to all connexins engaging in the same cellular processes. Innovations in high-resolution cryo-electron microscopy have revealed important insights into the structure of functionally important domains of both hemichannels and channels. These and other studies have established a foundation of knowledge that should allow inhibitory smart drug design for situations where enhanced intercellular or hemichannel activity is at the root of a connexin-linked disease. Assessment of the connexin interactome, which varies widely for each connexin subtype, continues to provide regulatory insights into the assembly and function of connexins that exhibit a short half-life. As the most intensely studied, Cx43 is found in about 50% of all human cell types and is extensively regulated by multiple inhibitory and enhancing phosphorylation events that have direct implications on tissue function and outcomes of disease, including cancer. Here, we briefly discuss these advances and give our thoughts on where the field is headed.","PeriodicalId":73016,"journal":{"name":"Faculty reviews","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46824929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Neuronal classifications that group neurons based on specific features/behaviors have become essential to further analyze the different subtypes in a systematic and reproducible way. A comprehensive taxonomic framework, accounting for multiple defining and quantitative features, will provide the reference to infer generalized rules for cells ascribed to the same neuronal type, and eventually predict cellular behaviors, even in the absence of experimental measures. Technologies that enable cell-type classification in the nervous system are rapidly evolving in scalability and resolution. While these approaches depict astonishing diversity in neuronal morphology, electrophysiology, and gene expression, a robust metric of the coherence between different profiling modalities leading to a unified classification is still largely missing. Focusing on GABAergic neurons of the cerebral cortex, Gouwens et al.1 pioneered the first integrated cell-type classification based on the simultaneous analysis of the transcriptional networks, the recording of intrinsic electrophysiological properties, and the reconstruction of 3D morphologies of the same cell. Their comprehensive and high-quality data provide a new framework to shed light on what may be considered a \"neuronal cell type.\"","PeriodicalId":73016,"journal":{"name":"Faculty reviews","volume":" ","pages":"13"},"PeriodicalIF":0.0,"publicationDate":"2022-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9190211/pdf/facrev-11-13.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40000048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nappi","doi":"10.12703/r/11-11","DOIUrl":"https://doi.org/10.12703/r/11-11","url":null,"abstract":"Premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) are common disorders of the luteal phase of the menstrual cycle and are characterized by moderate to severe physical, affective, or behavioral symptoms that impair daily activities and quality of life. PMS and PMDD have recently raised great interest in the research community for their considerable global prevalence. The etiology of PMS/PMDD is complex. Ovarian reproductive steroids (estradiol and progesterone) are considered pathogenetic effectors, but the key feature seems to be an altered sensitivity of the GABAergic central inhibitory system to allopregnanolone, a neurosteroid derived from progesterone produced after ovulation. Also, a reduced availability of serotonin seems to be involved. New insights point to a role for genetic and epigenetic modifications of hormonal and neurotransmitter pathways, and inflammation is the potential link between peripheral and neurological integrated responses to stressors. Thus, new therapeutic approaches to PMS/PMDD include inhibition of progesterone receptors in the brain (i.e., with ulipristal acetate), reduced conversion of progesterone to its metabolite allopregnanolone with dutasteride, and possible modulation of the action of allopregnanolone on the brain GABAergic system with sepranolone. Further research is needed to better understand the interaction between peripheral inflammatory molecules (cytokines, interleukins, C-reactive protein, and reactive oxygen species) and the brain neurotransmitter systems in women with PMS/PMDD. If confirmed, neuroinflammation could lead both to develop targeted anti-inflammatory therapies and to define prevention strategies for the associated chronic inflammatory risk in PMS/PMDD. Finally, the observed association between premenstrual disorders and psychological diseases may guide prompt and adequate interventions to achieve a better quality of life.","PeriodicalId":73016,"journal":{"name":"Faculty reviews","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48012097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
