Tumor-resident microbiota in breast cancer promotes cancer initiation and malignant progression.However,targeting microbiota to improve the effects of breast cancer therapy has not been investigated in detail.Here,we evaluated the microbiota composition of breast tumors and found that enterotoxigenic Bacteroides fragilis(ETBF)was highly enriched in the tumors of patients who did not respond to taxane-based neoadjuvant chemotherapy.ETBF,albeit at low biomass,secreted the toxic protein BFT-1 to promote breast cancer cell stemness and chemoresistance.Mechanistic studies showed that BFT-1 directly bound to NOD1 and stabilized NOD1 protein.NOD1 was highly expressed on ALDH+breast cancer stem cells(BCSCs)and cooperated with GAK to phosphorylate NUMB and promote its lysosomal degradation,thereby activating the NOTCH1-HEY1 signaling pathway to increase BCSCs.NOD1 inhibition and ETBF clearance increase the chemosensitivity of breast cancer by impairing BCSCs.

The gut microbiota plays a key role in host health and disease,particularly through their interactions with the immune system.Intestinal homeostasis is dependent on the symbiotic relationships between the host and the diverse gut microbiota,which is influenced by the highly co-evolved immune-microbiota interactions.The first step of the interaction between the host and the gut microbiota is the sensing of the gut microbes by the host immune system.In this review,we describe the cells of the host immune system and the proteins that sense the components and metabolites of the gut microbes.We further highlight the essential roles of pattern recognition receptors(PRRs),the G protein-coupled receptors(GPCRs),aryl hydrocarbon receptor(AHR)and the nuclear receptors expressed in the intestinal epithelial cells(IECs)and the intestine-resident immune cells.We also discuss the mechanisms by which the disruption of microbial sensing because of genetic or environmental factors causes human diseases such as the inflammatory bowel disease(IBD).

SARS-CoV-2 infection-induced hyper-inflammation is a key pathogenic factor of COVID-19.Our research,along with others',has demonstrated that mast cells(MCs)play a vital role in the initiation of hyper-inflammation caused by SARS-CoV-2.In previous study,we observed that SARS-CoV-2 infection induced the accumulation of MCs in the peri-bronchus and bronchioalveolar-duct junction in humanized mice.Additionally,we found that MC degranulation triggered by the spike protein resulted in inflammation in alveolar epithelial cells and capillary endothelial cells,leading to subsequent lung injury.The trachea and bronchus are the routes for SARS-CoV-2 transmission after virus inhalation,and inflammation in these regions could promote viral spread.MCs are widely distributed throughout the respiratory tract.Thus,in this study,we investigated the role of MCs and their degranulation in the development of inflammation in tracheal-bronchial epithelium.Histological analyses showed the accumulation and degranulation of MCs in the peri-trachea of humanized mice infected with SARS-CoV-2.MC degranulation caused lesions in trachea,and the formation of papillary hyperplasia was observed.Through transcriptome analysis in bronchial epithelial cells,we found that MC degranulation significantly altered multiple cellular signaling,particularly,leading to upregulated immune responses and inflammation.The administration of ebastine or loratadine effectively suppressed the induction of inflammatory factors in bronchial epithelial cells and alleviated tracheal injury in mice.Taken together,our findings confirm the essential role of MC degranulation in SARS-CoV-2-induced hyper-inflammation and the subsequent tissue lesions.Furthermore,our results support the use of ebastine or loratadine to inhibit SARS-CoV-2-triggered degranulation,thereby preventing tissue damage caused by hyper-inflammation.

Thermoplastic polyimides(PIs)with shape memory potential have received growing attention in recent years.In this work,highperformance thermoplastic PIs were fabricated by introducing PIs with chain rigidity(r-PI)into PI with chain flexibility(f-PI).The influences of molecular chain entanglement andπ-πinteractions on their thermomechanical and shape memory properties were investigated.The degree of molecular chain entanglement was quantitively characterized based on dynamic mechanical analysis(DMA).Theπ-πinteractions were investigated in detail by X-ray diffraction(XRD)and UV-Vis spectroscopy.It was found that the entanglement density increased andπ-πinteractions became stronger with the introduction of r-PI into f-PI,leading to the improvement of shape recovery.Moreover,a broad and increased glass transition temperature(T_(g))was achieved,endowing the PIs with multiple shape memory properties.The synergistic effects of increased entanglement density and enhancedπ-πinteractions were beneficial to regulating interchain interactions and thereby achieving high shape memory performance of the PIs.

T lymphocytes in the intestinal mucosa: defense and tolerance

Cellular & Molecular Immunology 2019年第3期16卷 216-224页

Although lymphocytes are known to circulate throughout lymphoid tissues and blood,they also establish residency in nonlymphoid organs,most prominently in barrier tissues,such as the intestines.The adaptation of T lymphocytes to intestinal environments requires constant discrimination between natural stimulation from commensal flora and food and pathogens that need to be cleared.Genetic variations that cause a defective defense or a break in tolerance along with environmental cues,such as infection or imbalances in the gut microbiota known as dysbiosis,can trigger several immune disorders via the activation of T lymphocytes in the intestines.Elucidation of the immune mechanisms that distinguish between commensal flora and pathogenic organisms may reveal therapeutic targets for the prevention or modulation of inflammatory diseases and boost the efficacy of cancer immunotherapy.In this review,we discuss the development and adaptation of T lymphocytes in the intestine,how these cells protect the host against pathogenic infections while tolerating food antigens and commensal microbiota,and the potential implications of targeting these cells for disease management and therapeutics.

Multiple signal strategies remarkably improve the accuracy and efficiency of electrochemiluminescence(ECL)immunoassays,but the lack of potential-resolved luminophore pairs and chemical cross talk hinders their development.In this study,we synthesized a series of gold nanoparticles(AuNPs)/reduced graphene oxide(Au/rGO)composites as adjustable oxygen reduction reaction and oxygen evolution reaction catalysts to promote and modulate tris(2,2′-bipyridine)ruthenium(II)(Ru(bpy)_(3)^(2+))’s multisignal luminescence.With the increase in the diameter of AuNPs(3 to 30 nm),their ability to promote Ru(bpy)_(3)^(2+)’s anodic ECL was first impaired and then strengthened,and cathodic ECL was first enhanced and then weakened.Au/rGOs with medium-small and medium-large AuNP diameters remarkably increased Ru(bpy)_(3)^(2+)’s cathodic and anodic luminescence,respectively.Notably,the stimulation effects of Au/rGOs were superior to those of most existing Ru(bpy)_(3)^(2+)co-reactants.Moreover,we proposed a novel ratiometric immunosensor construction strategy using Ru(bpy)_(3)^(2+)’s luminescence promoter rather than luminophores as tags of antibodies to achieve signal resolution.This method avoids signal cross talk between luminophores and their respective co-reactants,which achieved a good linear range of 10−7 to 10−1 ng/ml and a limit of detection of 0.33 fg/ml for detecting carcinoembryonic antigen.This study addresses the previous scarcity of the macromolecular co-reactants of Ru(bpy)_(3)^(2+),broadening its application in biomaterial detection.Furthermore,the systematic clarification of the detailed mechanisms for converting the potential-resolved luminescence of Ru(bpy)_(3)^(2+)could facilitate an in-depth understanding of the ECL process and should inspire new designs of Ru(bpy)_(3)^(2+)luminescence enhancers or applications of Au/rGOs to other luminophores.This work removes some impediments to the development of multisignal ECL biodetection systems and provides vitality into their widespread applications.
