In this review, we consider a conceptual framework whereby the virus itself is a reservoir of peptide motifs with pro-inflammatory activity. These motifs can potentially be liberated by highly variable proteolytic processing by the host. We focus on the ability of viral peptide motifs that can mimic innate immune peptides (more commonly known as ‘antimicrobial peptides’ (AMPs)). AMPs (and their ‘xenoAMP’ mimics) are not themselves pathogen-associated molecular patterns (PAMPs) that activate innate immunity via recognition by host pattern recognition receptors (PRRs) but can strongly amplify PRR activation via promoting multivalent PAMP presentation. An important mechanism in the host’s immune amplification machinery and is implicated in a range of autoimmune conditions, including lupus and rheumatoid arthritis, which are among the sequelae of COVID-19. We review experiments that show AMPs and SARS-CoV-2-derived xenoAMP can assemble with PAMPs such as dsRNA into pro-inflammatory complexes, resulting in cooperative, multivalent immune recognition by PRRs and grossly amplified inflammatory responses, a phenomenon generally not observed in harmless coronavirus homologs. We also review the persistence of viral remnants from other viral infections and their association with inflammatory sequelae long after the infection has been cleared.</div></div>","PeriodicalId":295,"journal":{"name":"Current Opinion in Solid State & Materials Science","volume":"33 ","pages":"Article 101191"},"PeriodicalIF":12.2,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142315828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electrochemical random-access memories (ECRAMs) are developed specifically to implement efficient analog in-memory computing for these data-intensive workloads, showing some critical advantages over competing memory technologies mostly developed originally for digital electronics. ECRAMs possess the distinctive capability to switch between a very large number of memristive states with a high level of symmetry, small cycle-to-cycle variability, and low energy consumption; and they simultaneously exhibit good endurance, long data retention, fast switching speed up to nanoseconds, and verified scalability down to sub-50 nm regime, therefore holding great promise in realizing deep-learning accelerators when heterogeneously integrated with silicon-based peripheral circuits. In this review, we first examine challenges in constructing in-memory-computing accelerators and unique advantages of ECRAMs. We then critically assess the various ionic species, channel materials, and solid-state electrolytes employed in ECRAMs that influence device programming characteristics and performance metrics with their different memristive modulation and ionic transport mechanisms. Furthermore, ECRAM device engineering and integration schemes are discussed, within the context of their implementation in high-density pseudo-crossbar array microarchitectures for performing DNN inference and training with high parallelism. Finally, we offer our insights regarding major remaining obstacles and emerging opportunities of harnessing ECRAMs to realize deep-learning accelerators through material-device-circuit-architecture-algorithm co-design.</p></div>","PeriodicalId":295,"journal":{"name":"Current Opinion in Solid State & Materials Science","volume":"32 ","pages":"Article 101187"},"PeriodicalIF":12.2,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1359028624000536/pdfft?md5=33fbb3f4ff0a27b0a69d3fcaa7f064ea&pid=1-s2.0-S1359028624000536-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142136393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their layered structures allow a straightforward identification of the monolayers as 2D structures. Today, 2D structures are reported from a wide class of materials ranging from molecules to thin non-van der Waals layers, generating interest across a large variety of scientific fields.
