文摘Cadmium accumulation in seafood has become a major concern for human health.Recently,there has been an increasing focus on the potential risks associated with food-borne fluorescent carbon dots(CDs)that are formed during the thermal processing of seafood.The co-occurrence of cadmium and CDs from cooked seafood become a common phenomenon and co-exposure of them to human has been an inevitable route during long-term seafood consuming.In addition,it has been widely recognized that CDs can be used as nanocarriers for metal ion chelation for their transport into organisms,thereby,they could influence the bioavailability of metal ion.While there have been numerous studies on the toxic effects of cadmium or CDs,none have explored the combined toxicity of food-borne CDs from clams(CCDs)and Cd^(2+).In this study,we investigated the single or co-exposure(combined exposure)of Cd^(2+)and CCDs on PC12 cells to investigate the combined toxicity of them.Our analysis of cell viability revealed that CCDs significantly augmented the cytotoxicity induced by Cd^(2+).More in-depth metabolomics and lipidomics investigation indicated that the combined exposure of Cd^(2+)and CCDs led to significant metabolic disorders,causing an antagonistic effect on energy metabolism,and a synergistic effect on amino acids and lipids metabolism.The disturbance in metabolomics and lipidomics was further supported by the disruption of mitochondrial membrane potential and the accumulation of reactive oxygen species following co-exposure.These findings provide new evidence that support the enhanced cytotoxicity of Cd^(2+)by the CCDs derived from the thermal processing of clams.This study also declares the necessary that prioritize the investigation of the potential impact of other thermal processing hazards originating from heat-processed foods on the toxicity of heavy metal ions.

文摘In order to ensure food safety,controlling foodborne pathogen contamination is of utmost importance.Growing apprehensions regarding the safety of synthetic antimicrobials,due to their adverse health effects,have prompted a search for alternative options.Plant natural products(PNPs)with antimicrobial activity are being explored as a viable alternative.Among the various antimicrobial natural products studied,plant essential oils,plant flavonoids,plant polyphenols,plant polysaccharides,and plant antimicrobial peptides have been identified as potential candidates.PNPs demonstrate a diverse array of antimicrobial mechanisms,encompassing cell wall and membrane damage,interference with genetic replication,disruption of energy metabolism,and induction of oxidative stress at the single-cell level,as well as inhibition of biofilm formation and quorum sensing at the population level.Certain PNPs have been harnessed as natural antimicrobial agents for the food preservation.The utilization of encapsulation technology proves to be an effective strategy in protecting PNPs,thereby ensuring good antimicrobial efficacy,enhanced dispersibility,and controlled release within food products.The utilization of nanoemulsions,nanoliposomes,edible packaging,electrospun nanofibers,and microcapsules formed by encapsulation has enriched the ways in which PNPs can be applied in food preservation.Although PNPs have great potential in food preservation,their widespread application in the food industry is currently constrained by factors such as production costs,safety concerns,and legal considerations.Chemical synthesis and biosynthesis pathways offer viable strategies for reducing the cost of producing PNPs,and ongoing efforts to assess safety and improve regulatory frameworks are likely to facilitate the broader adoption of PNPs in food preservation practices.This article provides an overview of the main types of PNPs with antimicrobial activity and their properties,focusing on their mechanisms of action.Additionally,it summarizes the use of PNPs in food preservation and discusses the characteristics and applications of different encapsulation technologies.Lastly,the paper briefly analyzes current limitations and proposes potential future trends for this field.

文摘Respiratory infections are associated with high morbidity and mortality and are a major global health problem[1].Acute respiratory infections are caused by multiple respiratory pathogens,including viruses and bacteria.Viral-bacterial co-infections,which have become increasingly common and a global concern,can lead to substantial complications,causing higher morbidity and adverse prognosis[2].Previous studies have reported low positive detection rates of targeted pathogens related to acute respiratory infections,owing to the limited number of detected pathogens and variations in the sensitivity of diagnostic methods[3-4].Low positive detection rates may impede our understanding of respiratory pathogen characteristics and hamper the development of precise treatment and prevention strategies.

文摘Neurodegenerative diseases are a class of disorders with the gradual loss of the central nervous system and peripheral nervous system.Neurodegenerative diseases manifest primarily as cognitive and behavioral disorders that adversely affect the lives of millions of people worldwide.Therefore,it is necessary to elucidate the mechanism of neurodegenerative diseases further and find effective new therapies.In recent years,increasing evidence has shown that the immune system plays a significant role in the pathophysiology of neurodegenerative diseases and regulates this process.The central and peripheral immune systems exert different roles in the disease progression.The development of neurodegenerative diseases is influenced by interactions between them.This review focuses on how the immune system,including microglia mediated nucleotide-binding oligomerization domain-like receptor protein 3 inflammation activation and T cell-mediated neuroinflammation,interactions with neurodegenerative diseases by modulating protein aggregation and blood-brain barrier permeability.Besides,we gave particular attention to glial cell-centered multicellular interactions and the inflammatory signaling pathway.Insight into the immune system’s functions and cellular interactions is essential for progressing disease research.In addition,the functions and mechanisms of these immune cells also suggest new ideas and targets for treatment.Therefore,this review summarizes some of the existing treatment strategies for amyloid-beta,tau,neuroinflammation,α-synuclein,associated microbiota,immune modulation,and neural injury repair.In addition,this review summarizes and compares animal models of different common neurodegenerative diseases and clinical research progress.In view of the current research status,new research directions and suggestions are proposed.

文摘NADC34-like porcine reproductive and respiratory syndrome virus(PRRSV),which first appeared in China in 2017,is currently one of the main epidemic strains in China.In this study,we found that a new variant of NADC34-like PRRSV evolved,named the L1A variant.The phylogenetics,epidemic status,and pathogenicity of the LA variants were subsequently comprehensively evaluated.Based on the results of the ORF5 phylogenetic analysis,the L1A variants were classified as NADC34-like PPRSV.All the strains had the same discontinuous 131-aa deletion in the NSP2 region(similar to that in the NADC30).Recombination analysis revealed that the L1A variants were recombinant viruses that contained an NADC30-like PRRSV skeleton,a nonstructural protein-encoding gene region obtained in part from JXA1-like PRRSV and a ORF2-ORF6 gene region partly obtained from NADC34-like PRRSV and that exhibited similar recombination patterns.We successfully isolated the L1A variant TZJ2756 from PAMs and Marc-145 cells.In animal experiments,TZJ2756 exhibited moderate pathogenicity in piglets,causing obvious clinical symptoms,namely,persistent fever,significantly reduced body weight,interstitial edema and severe interstitial pneumonia in the lungs,and prolonged high-load viremia.L1A variants have been detected in at least 12 provinces in China and share many similar epidemiological characteristics with the American L1C variant.This research will enhance our understanding of the prevalence of L1A variants and furnish valuable data for the ongoing monitoring of NADC34-like PRRSV in China.

文摘Multiple sclerosis is a severe autoimmune disorder that is mainly mediated by pathogenic cluster of CD4^(+)T cell subsets.Despite advancements in the management of multiple sclerosis,there is a critical need for more effective and safer treatments.In the present study,we administered Lycium barbarum glycopeptide to a mouse model of experimental autoimmune encephalomyelitis-an animal model of multiple sclerosis-and evaluated its effects on pathogenic CD4^(+)T cell activation both in vivo and in vitro.Lycium barbarum glycopeptide significantly mitigated the clinical severity of experimental autoimmune encephalomyelitis,as demonstrated by reduced demyelination and neuroinflammation.Moreover,Lycium barbarum glycopeptide treatment decreased the infiltration of peripheral leukocytes into the central nervous system and suppressed pro-inflammatory cytokine expression.Lycium barbarum glycopeptide also modulated pathogenic CD4^(+)T cell activation by inhibiting T helper 1/T helper 17 cell differentiation while promoting regulatory T cell expansion.Notably,no side effects were observed,suggesting the long-term safety and tolerability of Lycium barbarum glycopeptide.Furthermore,RNA sequencing data indicated that Lycium barbarum glycopeptide inhibits activator protein-1,an essential regulator of T cell activation and differentiation.This finding was supported by the reversal of T helper/T helper 17 cell response suppression upon AP-1 blockade.Collectively,these results highlight the potential of Lycium barbarum glycopeptide as an innovative therapeutic agent for CD4^(+)T cell-associated autoimmune or inflammatory diseases,such as multiple sclerosis.
