| 2 | Highly Stretchable,Elastic,and Sensitive MXene-Based Hydrogel for Flexible Strain and Pressure Sensors显示文摘Electronic skin is driving the next generation of cutting-edge wearable electronic products due to its good wearability and high accuracy of information acquisition.However,it remains a challenge to fulfill the requirements on detecting full-range human activities with existing flexible strain sensors.Herein,highly stretchable,sensitive,and multifunctional flexible strain sensors based on MXene-(Ti_(3)C_(2)T_(x)-)composited poly(vinyl alcohol)/polyvinyl pyrrolidone double-network hydrogels were prepared.The uniformly distributed hydrophilic MXene nanosheets formed a three-dimensional conductive network throughout the hydrogel,endowing the flexible sensor with high sensitivity.The strong interaction between the double-network hydrogel matrix and MXene greatly improved the mechanical properties of the hydrogels.The resulting nanocomposited hydrogels featured great tensile performance(2400%),toughness,and resilience.Particularly,the as-prepared flexible pressure sensor revealed ultrahigh sensitivity(10.75 kPa^(-1))with a wide response range(0-61.5 kPa),fast response(33.5 ms),and low limit of detection(0.87 Pa).Moreover,the hydrogel-based flexible sensors,with high sensitivity and durability,could be employed to monitor fullrange human motions and assembled into some aligned devices for subtle pressure detection,providing enormous potential in facial expression and phonation recognition,handwriting verification,healthy diagnosis,and wearable electronics. | Yao Lu Xinyu Qu Wen Zhao Yanfang Ren Weili Si Wenjun Wang Qian Wang Wei Huang Xiaochen Dong | 2020 | Research2020，，1： | 14 |
| 3 | Receptome profiling identifies KREMEN1 and ASGR1 as alternative functional receptors of SARS-CoV-2显示文摘Host cellular receptors play key roles in the determination of virus tropism and pathogenesis.However,little is known about SARS-CoV-2 host receptors with the exception of ACE2.Furthermore,ACE2 alone cannot explain the multi-organ tropism of SARS-CoV-2 nor the clinical differences between SARS-CoV-2 and SARS-CoV,suggesting the involvement of other receptor(s).Here,we performed genomic receptor profiling to screen 5054 human membrane proteins individually for interaction with the SARS-CoV-2 capsid spike(S)protein.Twelve proteins,including ACE2,ASGR1,and KREMEN1,were identified with diverse S-binding affinities and patterns.ASGR1 or KREMEN1 is sufficient for the entry of SARS-CoV-2 but not SARS-CoV in vitro and in vivo.SARS-CoV-2 utilizes distinct ACE2/ASGR1/KREMEN1(ASK)receptor combinations to enter different cell types,and the expression of ASK together displays a markedly stronger correlation with virus susceptibility than that of any individual receptor at both the cell and tissue levels.The cocktail of ASK-related neutralizing antibodies provides the most substantial blockage of SARS-CoV-2 infection in human lung organoids when compared to individual antibodies.Our study revealed an interacting host receptome of SARS-CoV-2,and identified ASGR1 and KREMEN1 as alternative functional receptors that play essential roles in ACE2-independent virus entry,providing insight into SARS-CoV-2 tropism and pathogenesis,as well as a community resource and potential therapeutic strategies for further COVID-19 investigations. | Yunqing Gu Jun Cao Xinyu Zhang Hai Gao Yuyan Wang Jia Wang Juan He Xiaoyi Jiang Jinlan Zhang Guanghui Shen Jie Yang Xichen Zheng Gaowei Hu Yuanfei Zhu Shujuan Du Yunkai Zhu Rong Zhang Jianqing Xu Fei Lan Di Qu Guoliang Xu Yun Zhao Dong Gao Youhua Xie Min Luo Zhigang Lu | 2022 | Cell Research2022，32，1： | 8 |

| 6 | Iron metabolism,ferroptosis,and lncRNA in cancer: knowns and unknowns显示文摘Cancer cells undergo substantial metabolic alterations to sustain increased energy supply and uncontrolled proliferation.As an essential trace element,iron is vital for many biological processes.Evidence has revealed that cancer cells deploy various mechanisms to elevate the cellular iron concentration to accelerate proliferation.Ferroptosis,a form of cell death caused by iron-catalyzed excessive peroxidation of polyunsaturated fatty acids(PUFAs),is a promising therapeutic target for therapyresistant cancers.Previous studies have reported that long noncoding RNA(lncRNA)is a group of critical regulators involved in modulating cell metabolism,proliferation,apoptosis,and ferroptosis.In this review,we summarize the associations among iron metabolism,ferroptosis,and ferroptosis-related lncRNA in tumorigenesis.This information will help deepen understanding of the role of lncRNA in iron metabolism and raise the possibility of targeting lncRNA and ferroptosis in cancer combination therapy. | Lei QU Xinyu HE Qian TANG Xiao FAN Jian LIU Aifu LIN | 2022 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2022，23，10： | 3 |
| 7 | A male-ABCD algorithm for hepatocellular carcinoma risk prediction in HBs Ag carriers显示文摘Objective: Hepatocellular carcinoma(HCC) development among hepatitis B surface antigen(HBs Ag) carriers shows gender disparity, influenced by underlying liver diseases that display variations in laboratory tests. We aimed to construct a risk-stratified HCC prediction model for HBs Ag-positive male adults.Methods: HBs Ag-positive males of 35-69 years old(N=6,153) were included from a multi-center populationbased liver cancer screening study. Randomly, three centers were set as training, the other three centers as validation. Within 2 years since initiation, we administrated at least two rounds of HCC screening using Bultrasonography and α-fetoprotein(AFP). We used logistic regression models to determine potential risk factors,built and examined the operating characteristics of a point-based algorithm for HCC risk prediction.Results: With 2 years of follow-up, 302 HCC cases were diagnosed. A male-ABCD algorithm was constructed including participant's age, blood levels of GGT(γ-glutamyl-transpeptidase), counts of platelets, white cells,concentration of DCP(des-γ-carboxy-prothrombin) and AFP, with scores ranging from 0 to 18.3. The area under receiver operating characteristic was 0.91(0.90-0.93), larger than existing models. At 1.5 points of risk score,26.10% of the participants in training cohort and 14.94% in validation cohort were recognized at low risk, with sensitivity of identifying HCC remained 100%. At 2.5 points, 46.51% of the participants in training cohort and 33.68% in validation cohort were recognized at low risk with 99.06% and 97.78% of sensitivity, respectively. At 4.5 points, only 20.86% of participants in training cohort and 23.73% in validation cohort were recognized at high risk,with positive prediction value of 22.85% and 12.35%, respectively.Conclusions: Male-ABCD algorithm identified individual's risk for HCC occurrence within short term for their HCC precision surveillance. | Yuting Wang Minjie Wang He Li Kun Chen Hongmei Zeng Xinyu Bi Zheng Zhu Yuchen Jiao Yong Wang Jian Zhu Hui Zhao Xiang Liu Chunyun Dai Chunsun Fan Can Zhao Deyin Guo Hong Zhao Jianguo Zhou Dongmei Wang Zhiyuan Wu Xinming Zhao Wei Cui Xuehong Zhang Jianqiang Cai Wanqing Chen Chunfeng Qu | 2021 | Chinese Journal of Cancer Research2021，33，3： | 3 |
| 8 | Thermoresponsive Lignin-Reinforced Poly(Ionic Liquid)Hydrogel Wireless Strain Sensor显示文摘To meet critical requirements on flexible electronic devices,multifunctionalized flexible sensors with excellent electromechanical performance and temperature perception are required.Herein,lignin-reinforced thermoresponsive poly(ionic liquid)hydrogel is prepared through an ultrasound-assisted synthesized method.Benefitting from the electrostatic interaction between lignin and ionic liquid,the hydrogel displays high stretchability(over 1425%),excellent toughness(over 132 kPa),and impressive stress loading-unloading cyclic stability.The hydrogel strain sensor presents excellent electromechanical performance with a high gauge factor(1.37)and rapid response rate(198 ms),which lays the foundation for human body movement detection and smart input.Moreover,owing to the thermal-sensitive feature of poly(ionic liquid),the as-prepared hydrogel displays remarkable thermal response sensitivity(0.217℃^(-1))in body temperature range and low limit of detection,which can be applied as a body shell temperature indicator.Particularly,the hydrogel can detect dual stimuli of strain and temperature and identify each signal individually,showing the specific application in human-machine interaction and artificial intelligence.By integrating the hydrogel strain sensor into a wireless sensation system,remote motion capture and gesture identification is realized in real-time. | Xinyu Qu Ye Zhao Zi’ang Chen Siying Wang Yanfang Ren Qian Wang Jinjun Shao Wenjun Wang Xiaochen Dong | 2021 | Research2021，，1： | 3 |
| 9 | MXene-composited highly stretchable,sensitive and durable hydrogel for flexible strain sensors显示文摘The flourishing development in flexible electronics has provoked intensive research in flexible strain sensors to realize accurate perception acquisition under different external stimuli.However,building hydrogel-based strain sensors with high stretchability and sensitivity remains a great challenge.Herein,MXene nanosheets were composited into polyacrylamide-sodium alginate matrix to construct mechanical robust and sensitive double networked hydrogel strain sensor.The hydrophilic MXene nanosheets formed strong interactions with the polymer matrix and endowed the hydrogel with excellent tensile properties(3150%),compliant mechanical strength(2.03 kPa^(-1)in Young’s Module)and long-lasting stability and fatigue resistance(1000 dynamic cycles under 1,600%strain).Due to the highly oriented MXene-based three dimensional conductive networks,the hydrogel sensor achieved extremely high tensile sensitivity(18.15 in gauge factor)and compression sensitivity(0.38 kPa^(-1)below 3 kPa).MXene hydrogel-based strain sensors also displayed negligible hysteresis in electromechanical performance,typical frequent-independent feature and rapid response time to external stimuli.Moreover,the sensor exhibited accurate response to different scales of human movements,providing potential application in speech recognition,expression recognition and handwriting verification. | Wei Yuan Xinyu Qu Yao Lu Wen Zhao Yanfang Ren Qian Wang Wenjun Wang Xiaochen Dong | 2021 | Chinese Chemical Letters2021，32，6： | 3 |
| 10 | Ultradurable,freeze-resistant,and healable MXene-based ionic gels for multi-functional electronic skin显示文摘Hydrogel is a potential matrix material of electronic-skins(E-skins)because of its excellent ductility,tunability,and biocompatibility.However,hydrogel-based E-Skins will inevitably lose their sensing performance in practical applications for water loss,physical damage,and ambient interferences.It remains a challenge to manufacture highly durable gel-based E-skins.Herein,an E-Skin is fabricated by introducing ionic liquids(ILs)into MXene-composited binary polymer network.The obtained ionic gel shows excellent mechanical properties,strong adhesion,and superior tolerance to harsh environments.The E-skin exhibits high sensitivity to both strain and pressure in a wide range of deformations,which enables a monitoring function for various human motions and physiological activities.Importantly,the E-skin shows consistent electrical response after being stored in the open air for 30 days and can be quickly healed by irradiation with 808 nm near-infrared light,originating from the photo-thermal effect induced self-healing acceleration.It is noteworthy that the E-skin also reveals a highly sensitive perception of temperature and near-infrared light,displaying the promising potential applications in the multifunctional flexible sensor. | Yao Lu Xinyu Qu Siying Wang Ye Zhao Yanfang Ren Wenli Zhao Qian Wang Chencheng Sun Wenjun Wang Xiaochen Dong | 2022 | Nano Research2022，15，5： | 2 |

| 12 | Photosynthetic response of floating Ulva prolifera to diurnal changes of in-situ environments on the sea surface显示文摘During yellow sea green tide outbreak, the thalli of Ulva prolifera drifted more than 350 km on the sea surface from off shore of Jiangsu Province to Qingdao city, where they were exposed to complex changes of local environments. The purpose of this study is to investigate the response of the thalli to diurnal changes of environments on the sea surface, and a sea surface environment simulator (SSES) was designed to simulate the natural environment of floating U . prolifera mat. A control experiment is designed in the laboratory, which was processed under suitable conditions (20°C for temperature, 72 μmol photons/(m 2 ·s) for light intensity and 30 for salinity), and an in-situ research was conducted to study the photosynthetic responses of floating U . prolifera to diurnal changes of environments. The results show that the photosynthetic efficiency of the thalli decreased gradually with time, and decreased rapidly after 14:00 local time (LT). After exposed to the environment on the sea surface for 6 h, the photosynthetic activity of the thalli decreased significantly. Furthermore, physiological-level and molecular-level experiments revealed that non-photochemical quenching (NPQ), cyclic electron flow (CEF) and energy redistribution between PSI and PSII all played an important role in the strong photosynthetic plasticity of U . prolifera . NPQ is the most important photoprotective responses to environmental changes before 12:00 LT. The results also confirmed that the CEF and energy redistribution between PSI and PSII are the main synergistic eff ects for the thalli to adapt to the environmental changes when the process NPQ cannot work. And the result can further reveal the reason why U . prolifera can adapt to the living condition of long distance drift on the sea surface. The findings of this research could provide a theoretical basis for explaining outbreaks of the green tide and instructing the management of the problem. | ZHAO Xinyu TANG Xuexi HU Shunxin ZHONG Yi QU Tongfei WANG Ying | 2019 | Journal of Oceanology and Limnology2019，37，2： | 2 |
| 13 | Chemotherapy initiation with single-course methotrexate alone or combined with dactinomycin versus multi-course methotrexate for low-risk gestational trophoblastic neoplasia: a multi-centric randomized clinical trial显示文摘We aimed to evaluate the effectiveness and safety of single-course initial regimens in patients with low-risk gestational trophoblastic neoplasia(GTN).In this trial (NCT01823315),276 patients were analyzed.Patients were allocated to three initiated regimens:single-course methotrexate(MTX),single-course MTX+dactinomycin(ACTD),and multi-course MTX(control arm).The primary endpoint was the complete remission(CR)rate by initial drug(s).The primary CR rate was 64.4%with multi-course MTX in the control arm.For the single-course MTX arm,the CR rate was 35.8%by one course;it increased to 59.3%after subsequent multi-course MTX,with non-inferiority to the control(difference-5.1%,95%confidence interval(CI)-19.4%to 9.2%,P=0.014).After further treatment with multi-course ACTD,the CR rate(93.3%)was similar to that of the control(95.2%,P=0.577).For the single-course MTX+ACTD arm,the CR rate was 46.7%by one course,which increased to 89.1%after subsequent multi-course,with non-inferiority(difference 24.7%,95%CI 12.8%-36.6%,P<0.001)to the control.It was similar to the CR rate by MTX and further ACTD in the control arm(89.1%vs.95.2%,P=0.135).Four patients experienced recurrence,with no death,during the 2-year follow-up.We demonstrated that chemotherapy initiation with single-course MTX may be an alternative regimen for patients with low-risk GTN. | Lili Chen Ling Xi Jie Jiang Rutie Yin Pengpeng Qu Xiuqin Li Xiaoyun Wan Yaxia Chen Dongxiao Hu Yuyan Mao Zimin Pan Xiaodong Cheng Xinyu Wang Qingli Li Danhui Weng Xi Zhang Hong Zhang Quanhong Ping Xiaomei Liu Xing Xie Beihua Kong Ding Ma Weiguo Lu | 2022 | Frontiers of Medicine2022，16，2： | 2 |
| 14 | Inducing the SnO2-based electron transport layer into NiFe LDH/NF as efficient catalyst for OER and methanol oxidation reaction显示文摘In an electrocatalyst with a heterointerface structure,the different interfaces can efficiently adjust the catalyst’s conductivity and electron arrangement,thereby enhancing the activity of the electrocatalyst.Ultrathin and smaller Ni Fe LDH was successfully constructed on the surface of SnOnanosheet supported NF by layer by layer assembly,and exhibits lower overpotential of 234 mV at a current density of 10 m A cm,which only increases by 6.4%even at a high current density of 100 mA cm.The excellent OER activity of catalyst is attributed to the contribution of the semiconductor SnOelectron transport layer.Through experiments and characterization,3d structure SnOnanosheets control the growth of ultra-thin nickel-iron,the hierarchical interface between SnOand Ni Fe LDH can change the electron arrangement around the iron and nickel active centers at the interface,resulting the valence states of iron slightly increased and Nicontent increased.The result will promote the oxidation of water.Meanwhile,the SnOsemiconductor as electron transport layer is conducive to trapping electrons generated in oxidation reaction,promoting electrons transferring from the Ni Fe LDH active center to the Ni substrate more quickly,and enhance the activity of Ni Fe LDH.It also shows excellent activity in an electrolyte solution containing 0.5 M methanol and 1 M KOH,and only 1.396 V(vs.RHE)is required to drive a current density of 10 mA cm. | Changwu Wan Jie Jin Xinyu Wei Shizhuo Chen Yi Zhang Tenglong Zhu Hongxia Qu | 2022 | Journal of Materials Science & Technology2022，，29： | 1 |
| 15 | Carrier-free nanoprodrug for p53-mutated tumor therapy via concurrent delivery of zinc-manganese dual ions and ROS显示文摘Human cancers typically express a high level of tumor-promoting mutant p53 protein(Mutp53)with a minimal level of tumor-suppressing wild-type p53 protein(WTp53).In this regard,inducing Mutp53 degradation while activating WTp53 is a viable strategy for precise anti-tumor therapy.Herein,a new carrier-free nanoprodrug(i.e.,Mn-ZnO_(2)nanoparticles)was developed for concurrent delivery of dual Zn-Mn ions and reactive oxygen species(ROS)within tumor to regulate the p53 protein for high anti-tumor efficacy.In response to the mild tumor acidic environment,the released Zn^(2+)and H_(2)O_(2)from Mn-ZnO_(2)NPs induced ubiquitination-mediated proteasomal degradation of Mutp53,while the liberative Mn^(2+)and increased ROS level activated the ATM-p53-Bax pathway to elevate WTp53 level.Both in vitro and in vivo results demonstrated that pH-responsive decomposition of Mn-ZnO2 NPs could effectively elevate the intracellular dual Zn-Mn ions and ROS level and subsequently generate the cytotoxic hydroxyl radical(·OH)through the Fenton-like reaction.With the integration of multiple functions(i.e.,carrier-free ion and ROS delivery,tumor accumulation,p53 protein modulation,toxic·OH generation,and pH-activated MRI contrast)in a single nanosystem,Mn-ZnO_(2)NPs demonstrate its superiority as a promising nanotherapeutics for p53-mutated tumor therapy. | Jinping Wang Chang Qu Xinyue Shao Guoqiang Song Jingyu Sun Donghong Shi Ran Jia Hailong An Hongjun Wang | 2023 | Bioactive Materials2023，，2： | 1 |
| 16 | Atomic-level correlation between the electrochemical performance of an oxygen-evolving catalyst and the effects of CeO_(2) functionalization显示文摘Herein,we prepared a bimetallic layered double hydroxide(FeCo LDH)featuring a dandelion-like structure.Anchoring of CeO_(2)onto FeCo LDH produced interfaces between the functionalizing CeO_(2)and the parent LDH.Comparative electrochemical studies were carried out.Onset potential,overpotential,and Tafel slope point to the superior oxygen-evolving performance of CeO_(2)-FeCo LDH with respect to FeCo LDH,therefore,demonstrating the merits of CeO_(2)functionalization.The electronic structures of Fe,Co,and Ce were analyzed by X-ray photoelectron spectroscopy(XPS)and electron energy loss spectroscopy(EELS)from which the increase of Co^(3+)and the concurrent lowering of Ce^(4+)were established.With the use of CeO_(2)-FeCo LDH,accelerated formation at a sizably reduced potential of Co-OOH,one of the key intermediates preceding the release of O_(2)was observed by in situ Raman spectroscopy.We now have the atomic-level and location-specific evidence,the increase of the active Co^(3+)across the interface to correlate the enhanced catalytic performance with CeO_(2)functionalization. | Yanyan Li Wen Luo Duojie Wu Qi Wang Jie Yin Pinxian Xi Yongquan Qu Meng Gu Xinyu Zhang Zhouguang Lu Zhiping Zheng | 2022 | Nano Research2022，15，4： | 1 |
| 17 | Temperature-sensitive and solvent-resistance hydrogel sensor for ambulatory signal acquisition in“moist/hot environment”显示文摘To realize continuously and stably work in a“moist/hot environment”,flexible electronics with excellent humid resistance,antiswelling,and detection sensitivity are demanding.Herein,a solvent-resistant and temperature-ultrasensitive hydrogel sensor was prepared by combining MXene and quaternized chitosan(QCS)with the binary polymer chain.The strong electrostatic interaction between the QCS chain and the poly(acrylic acid)(PAA)network endows the hydrogel stability against solvent erosion,high temperature,and high humidity.The strong dynamic interaction between MXene and polymer matrix significantly improves the mechanical properties and sensing(strain and temperature)sensitivity of the hydrogel.The hydrogel strain sensor exhibits a high gauge factor(5.53),temperature/humidity tolerance(equilibrium swelling ratio of 2.5%at 80℃),and excellent cycle stability,which could achieve a remote and accurate perception of complex human motion and environment fluctuation under aquatic conditions.Moreover,the hydrogel sensor exhibits impressive thermal response sensitivity(-3.183%/℃),ultrashort response time(<2.53 s),and a low detection limit(<0.5℃)in a wide temperature range,which is applied as an indicator of the body surface and ambient temperature.In short,this study broadens the application scenarios of hydrogels in persistent extreme thermal and wet environments. | Xinyu Qu Hanjun Sun Xiaolong Kan Bing Lei Jinjun Shao Qian Wang Wenjun Wang Zhenhua Ni Xiaochen Dong | 2023 | Nano Research2023，16，7： | 0 |
| 18 | Thermal-sensitive ionogel with NIR-light controlled adhesion for ultrasoft strain sensor显示文摘With the widespread prevailing of flexible electronics in human-machine interfaces,health monitor,and human motion detection,ultrasoft flexible sensors are urgently desired with critical demands in conformality.Herein,a temperature-sensitive ionogel with near-infrared(NIR)-light controlled adhesion is prepared by electrostatic interaction of poly(diallyl dimethylammonium chloride)(PDDA)and acrylic acid,as well as the incorporation of the conductive polydopamine modified polypyrrole nanoparticles(PPy-PDA NPs).The PPy-PDA NPs could weaken the tough interaction between polymer chains and depress the Young’s modulus of the ionogel,thus promoting the ionogel ultrasoft(34 kPa)and highly stretchable(1,013%)performance to tensile deformations.In addition,the high photothermal conversion capacity of PPy-PDA NPs ensured the ionogel excellent NIR-light controlled adhesion and temperature sensitivity,which facilitated the ionogel on-demand removal and promised a reliable thermal sensor.Moreover,the resulted ultrasoft flexible sensor exhibited high sensitivity and stability to both strain and pressure in a broad range of deformations,enabling a precise monitoring on various human motions and physiological activities.The temperature-sensitive,ultrasoft,and controlled adhesive capabilities prompted great potential of the flexible ionogel in medical diagnosis and wearable electronics. | Bing Lei Longxue Cao Xinyu Qu Yunlong Liu Jinjun Shao Qian Wang Shuhong Li Wenjun Wang Xiaochen Dong | 2023 | Nano Research2023，16，4： | 0 |
| 19 | Uncovering hidden nodes and hidden links in complex dynamic networks显示文摘Inferring network structures from available data has attracted much interest in network science;however,in many realistic networks,only some of the nodes are perceptible while others are hidden,making it a challenging task.In this work,we develop a method for reconstructing the network with hidden nodes and links,taking account of fast-varying noise and time-delay interactions.By calculating the correlations of available data with different derivative orders for multiple pairs of accessible nodes,analyzing and integrating the relationships between different correlations,and defining diverse hidden-node-related reconstruction motifs,we can effectively identify the hidden nodes and hidden links in the network. | Zhaoyang Zhang Xinyu Wang Haihong Li Yang Chen Zhilin Qu Yuanyuan Mi Gang Hu | 2024 | Science China(Physics,Mechanics & Astronomy)2024，67，4： | 0 |
| 20 | Targeting cAMP in D1-MSNs in the nucleus accumbens, a new rapid antidepressant strategy显示文摘Studies have suggested that the nucleus accumbens(NAc)is implicated in the pathophysiology of major depression;however,the regulatory strategy that targets the NAc to achieve an exclusive and outstanding anti-depression benefit has not been elucidated.Here,we identified a specific reduction of cyclic adenosine monophosphate(cAMP)in the subset of dopamine D1 receptor medium spiny neurons(D1-MSNs)in the NAc that promoted stress susceptibility,while the stimulation of cAMP production in NAc D1-MSNs efficiently rescued depression-like behaviors.Ketamine treatment enhanced cAMP both in D1-MSNs and dopamine D2 receptor medium spiny neurons(D2-MSNs)of depressed mice,however,the rapid antidepressant effect of ketamine solely depended on elevating cAMP in NAc D1-MSNs.We discovered that a higher dose of crocin markedly increased cAMP in the NAc and consistently relieved depression 24 h after oral administration,but not a lower dose.The fast onset property of crocin was verified through multicenter studies.Moreover,crocin specifically targeted at D1-MSN cAMP signaling in the NAc to relieve depression and had no effect on D2-MSN.These findings characterize a new strategy to achieve an exclusive and outstanding anti-depression benefit by elevating cAMP in D1-MSNs in the NAc,and provide a potential rapid antidepressant drug candidate,crocin. | Yue Zhang Jingwen Gao Na Li Peng Xu Shimeng Qu Jinqian Cheng Mingrui Wang Xueru Li Yaheng Song Fan Xiao Xinyu Yang Jihong Liu Hao Hong Ronghao Mu Xiaotian Li Youmei Wang Hui Xu Yuan Xie Tianming Gao Guangji Wang Jiye Aa | 2024 | Acta Pharmaceutica Sinica B2024，14，2： | 0 |
