Inflammation as a cause of acute myocardial infarction in patients with myeloproliferative neoplasm

Myeloproliferative neoplasms(MPN)are a group of diseases characterized by the clonal proliferation of hematopoietic progenitor or stem cells.They are clinically classifiable into four main diseases:chronic myeloid leukemia,essential thrombocythemia,polycythemia vera,and primary myelofibrosis.These pathologies are closely related to cardio-and cerebrovascular diseases due to the increased risk of arterial thrombosis,the most common underlying cause of acute myocardial infarction.Recent evidence shows that the classical Virchow triad(hypercoagulability,blood stasis,endothelial injury)might offer an explanation for such association.Indeed,patients with MPN might have a higher number and more reactive circulating platelets and leukocytes,a tendency toward blood stasis because of a high number of circulating red blood cells,endothelial injury or overactivation as a consequence of sustained inflammation caused by the neoplastic clonal cell.These abnormal cancer cells,especially when associated with the JAK2V617F mutation,tend to proliferate and secrete several inflammatory cytokines.This sustains a pro-inflammatory state throughout the body.The direct consequence is the induction of a pro-thrombotic state that acts as a determinant in favoring both venous and arterial thrombus formation.Clinically,MPN patients need to be carefully evaluated to be treated not only with cytoreductive treatments but also with cardiovascular protective strategies.

Effects of Wuwei Xiaodu Decoction on Uterine Energy Metabolism and Serum Inflammatory Factors in Rats with Acute Pelvic Inflammatory Disease

[Objectives]To observe the effects of Wuwei Xiaodu Decoction on uterine energy metabolism and serum inflammatory factors in the acute pelvic inflammatory disease(APID)model.[Methods]75 Wistar rats(females)were randomly divided into control group,model group and Wuwei Xiaodu Decoction low,medium and high dose groups(n=15).Except for the control group,the rat APID model was established by right uterine inoculation.On the fifth day after inoculation,the low,medium and high dose groups of Wuwei Xiaodu Decoction were administered at 4,8 and 16 g/kg,and the control group and model group received normal saline.Rats were killed 12 h after nondose administration,blood was collected from the abdominal aorta and measured by ELISA for serum interleukin-6(interleukin-6,IL-6),IL-8,and C-reactive proteins(CRP);the right uterus of rats was tested for high-energy phosphate adenosine phosphate(AMP),adenosine diphosphate(ADP),adenosine triphosphate(ATP)and total adenine nucleotides(TAN)level to evaluate the uterine energy metabolism.[Results]AMP,ADP,ATP and TAN were significantly higher in the Wuwei Xiaodu Decoction of low,medium and high dose than the model group,while the serum IL-6,IL-8 and CRP were significantly lower than the model group,and the difference between the low,medium and high doses(P<0.05).[Conclusions]The Wuwei Xiaodu Decoction can dose-dependent promote uterine energy metabolism and inhibit inflammatory response in APID model rats.

The effect of Huanglian Jiedu Decoction on inflammatory factors and oxidative stress in patients with acute ischemic stroke

Objective:To study the clinical efficacy of Huanglian Jiedu decoction in treating acute ischemic stroke(AIS)and its effects on inflammatory factors and oxidative stress.Method:A total of 53 patients with AIS were recruited as the study subjects and randomly divided into a control group and a treatment group using a random number table method.The control group consisted of 26 patients and the treatment group consisted of 27 patients.The control group received conventional Western medicine treatment.The control group received routine Western medicine treatment,while the treatment group received Huanglian Jiedu decoction based on the control group,with 14 days as a course of treatment.The effects of Huanglian Jiedu decoction on neurological function and activities of daily living were evaluated using the National Institute of Health stroke scale(NIHSS)and activities of daily living(ADL)scores.The effects of Huanglian Jiedu decoction on inflammatory reactions and oxidative stress were evaluated by detecting interleukin-4(IL-4),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),transforming growth factorβ(TGF-β),total antioxidative capacity(T-AOC),malondialdehyde(MDA),superoxide dismutase(SOD),and catalase(CAT)levels.Results:After treatment with Huanglian Jiedu Decoction,the ALD scores of AIS patients in both groups increased,while the NISHH scores decreased,suggesting that Huanglian Jiedu Decoction has therapeutic effects on AIS patients.It also reduces the levels of serum IL-6,TNF-α,MDA in AIS patients and increases the levels of IL-4,TGF-β,CAT,SOD,T-AOC,suggesting that Huanglian Jiedu decoction can improve the anti-inflammatory and antioxidant abilities of AIS patients.Conclusion:Huanglian Jiedu decoction can help AIS patients recover their neurological function,increase their capacity for self-care in daily life,and strengthen the body’s anti-inflammatory and antioxidant defenses.

MicroRNA-29a-3p Prevents Drug-Induced Acute Liver Failure through Inflammation-Related Pyroptosis Inhibition

Objective Little is known about the role of microRNA-29a-3p(miR-29a-3p)in inflammation-related pyroptosis,especially in drug-induced acute liver failure(DIALF).This study aimed to identify the relationship between miR-29a-3p and inflammation-related pyroptosis in DIALF and confirm its underlying mechanisms.Methods Thioacetamide(TAA)-and acetaminophen(APAP)-induced ALF mouse models were established,and human samples were collected.The expression levels of miR-29a-3p and inflammation and pyroptosis markers were measured by quantitative real-time polymerase chain reaction(qRT-PCR),Western blotting,or immunochemical staining in miR-29a-3p knock-in transgenic mouse(MIR29A(KI/KI))DIALF models.In addition,RNA sequencing was conducted to explore the mechanisms.Results MiR-29a-3p levels were decreased in TAA-and APAP-induced DIALF models.MiR-29a-3p prevented DIALF caused by TAA and APAP.RNA sequencing and further experiments showed that the protective effect of miR-29a-3p on DIALF was mainly achieved through inhibition of inflammation-related pyroptosis,and the inhibition was dependent on activation of the PI3K/AKT pathway.In addition,miR-29a-3p levels were reduced,and pyroptosis was activated in both peripheral blood mononuclear cells and liver tissues of DIALF patients.Conclusion The study supports the idea that miR-29a-3p inhibits pyroptosis by activating the PI3K/AKT pathway to prevent DIALF.MiR-29a-3p may be a promising therapeutic target for DIALF.

Periplaneta Americana Extract Ameliorates LPS-induced Acute Lung Injury Via Reducing Inflammation and Oxidative Stress

Objective Acute lung injury(ALI)is an acute clinical syndrome characterized by uncontrolled inflammation response,which causes high mortality and poor prognosis.The present study determined the protective effect and underlying mechanism of Periplaneta americana extract(PAE)against lipopolysaccharide(LPS)-induced ALI.Methods The viability of MH-S cells was measured by MTT.ALI was induced in BALB/c mice by intranasal administration of LPS(5 mg/kg),and the pathological changes,oxidative stress,myeloperoxidase activity,lactate dehydrogenase activity,inflammatory cytokine expression,edema formation,and signal pathway activation in lung tissues and bronchoalveolar lavage fluid(BALF)were examined by H&E staining,MDA,SOD and CAT assays,MPO assay,ELISA,wet/dry analysis,immunofluorescence staining and Western blotting,respectively.Results The results revealed that PAE obviously inhibited the release of proinflammatory TNF-α,IL-6 and IL-1βby suppressing the activation of MAPK/Akt/NF-κB signaling pathways in LPS-treated MH-S cells.Furthermore,PAE suppressed the neutrophil infiltration,permeability increase,pathological changes,cellular damage and death,pro-inflammatory cytokines expression,and oxidative stress upregulation,which was associated with its blockage of the MAPK/Akt/NF-κB pathway in lung tissues of ALI mice.Conclusion PAE may serve as a potential agent for ALI treatment due to its anti-inflammatory and anti-oxidative properties,which correlate to the blockage of the MAPK/NF-κB and AKT signaling pathways.

Systemic inflammation response index and systemic immune-inflammation index for predicting complications of acute appendicitis:A retrospective study

Objective:To investigate the value of systemic inflammatory response index(SIRI)and systemic immune-inflammation index(SII)in predicating acute appendicitis complications based on hemogram parameters.Methods:Demographic data,histopathological studies,and laboratory results of the patients who were admitted to the emergency department with a complaint of abdominal pain between January 2020 and June 2022 and were hospitalized with the diagnosis of acute appendicitis for operation by general surgery were examined.Simple appendicitis and complicated appendicitis groups were compared in terms of parameters according to their histopathological examinations.Results:A total of 220 patients who met the inclusion criteria were included in our study.Mean SIRI levels were found to be significantly higher in the complicated appendicitis group than in the simple appendicitis group[6.60(4.07,14.40)vs.3.50(2.20,6.80);P=0.002].Similarly,SII levels were found to be significantly higher in the complicated appendicitis group compared to the simple appendicitis group[2514.50(1132.25,5388.00)vs.1207.00(571.50,2089.00),P<0.001].The power of SIRI and SII to indicate complications was higher than white blood cell count and C-reactive protein(area under the curve:0.753 and 0.786,respectively).Conclusion:SIRI and SII could be used to indicate complications in patients with acute appendicitis.

Pleuro-Pericardial Inflammation and Effusion: A Rare Acute Initial Presentation of Rheumatoid Arthritis

Background: Rheumatoid arthritis is a systemic inflammatory arthritis characterized by joint pain and morning stiffness. The affected joints are typically symmetrically affected, and given the inflammatory nature of this condition, patients often present with warmth and erythema around affected joints as well as fatigue. Extra-articular manifestations, especially pleuro-pericardial inflammation, are rare initial presentations, although may be seen in advanced or undertreated disease. Case Presentation: We describe a case of a rheumatoid arthritis presenting atypically in a middle-aged male who came to the emergency department complaining of diffuse muscle pain and swelling in the distal extremities. Cardiac ultrasound revealed pleuro-pericardial inflammation and effusions. Myositis and infectious causes were ruled out and bilateral hand x-rays did not show erosions or any evidence of arthritic changes. All rheumatological auto-antibodies were negative except for rheumatoid factor and anti-cyclic citrullinated peptide (CCP) and a diagnosis of rheumatoid arthritis was made. The patient was started on prednisone with excellent response. Conclusions: This case highlights that rheumatoid arthritis can uncommonly present initially with extra-articular manifestations that are often manifested in advanced disease. Typically, extra-articular manifestations, especially those as severe as this patient’s, occur with untreated, advanced disease and could accompany extensive arthritic joint changes. Thus, it is important to have an understanding of rare, atypical presentations of rheumatoid arthritis so that a high index of suspicion can be maintained to make the diagnosis and initiate treatment in a timely manner.

Protein-mediated interactions in the dynamic regulation of acute inflammation

Protein-mediated interactions are the fundamental mechanism through which cells regulate health and disease.These interactions require physical contact between proteins and their respective targets of interest.These targets include not only other proteins but also nucleic acids and other important molecules as well.These proteins are often involved in multibody complexes that work dynamically to regulate cellular health and function.Various techniques have been adapted to study these important interactions,such as affinity-based assays,mass spectrometry,and fluorescent detection.The application of these techniques has led to a greater understanding of how protein interactions are responsible for both the instigation and resolution of acute inflammatory diseases.These pursuits aim to provide opportunities to target specific protein interactions to alleviate acute inflammation.

Erratum to: Melatonin Alleviates Acute Gouty Inflammation In Vivo and In Vitro

The authors examined the original data of their work and noticed some mistakes.The ELISA kit was bought from IBL Co.Germany instead of Abcam Co,UK.The anti-NLRP3,anti-IL-1βand anti-caspase-1 primary antibodies were from CST Co,USA.There were 31 acute gout patients and 25 gout patients in remission who met the American Rheumatism Society(ACR)diagnostic criteria of gout in this study,and 7 normal individuals were recruited as controls.The authors sincerely apologize for the mistakes and confirm that the changes do not affect the scientific conclusion of the published work.

AGK2 pre-treatment protects against thioacetamide-induced acute liver failure via regulating the MFN2-PERK axis and ferroptosis signaling pathway

Background:Acute liver failure(ALF)is an unpredictable and life-threatening critical illness.The pathological characteristic of ALF is massive necrosis of hepatocytes and lots of inflammatory cells infiltration which may lead to multiple organ failure.Methods:Animals were divided into 3 groups,normal,thioacetamide(TAA,ALF model)and TAA+AGK2.Cultured L02 cells were divided into 5 groups,normal,TAA,TAA+mitofusin 2(MFN2)-siRNA,TAA+AGK2,and TAA+AGK2+MFN2-siRNA groups.The liver histology was evaluated with hematoxylin and eosin staining,inositol-requiring enzyme 1(IRE1),activating transcription factor 6β(ATF6β),protein kinase R(PKR)-like endoplasmic reticulum kinase(PERK)and phosphorylated-PERK(p-PERK).C/EBP homologous protein(CHOP),reactive oxygen species(ROS),MFN2 and glutathione peroxidase 4(GPX4)were measured with Western blotting,and cell viability and liver chemistry were also measured.Mitochondriaassociated endoplasmic reticulum membranes(MAMs)were measured by immunofluorescence.Results:The liver tissue in the ALF group had massive inflammatory cell infiltration and hepatocytes necrosis,which were reduced by AGK2 pre-treatment.In comparison to the normal group,apoptosis rate and levels of IRE1,ATF6β,p-PERK,CHOP,ROS and Fe2+in the TAA-induced ALF model group were significantly increased,which were decreased by AGK2 pre-treatment.The levels of MFN2 and GPX4 were decreased in TAA-induced mice compared with the normal group,which were enhanced by AGK2 pretreatment.Compared with the TAA-induced L02 cell,apoptosis rate and levels of IRE1,ATF6β,p-PERK,CHOP,ROS and Fe2+were further increased and levels of MFN2 and GPX4 were decreased in the MFN2-siRNA group.AGK2 pre-treatment decreased the apoptosis rate and levels of IRE1,ATF6β,p-PERK,CHOP,ROS and Fe2+and enhanced the protein expression of MFN2 and GPX4 in MFN2-siRNA treated L02 cell.Immunofluorescence observation showed that level of MAMs was promoted in the AGK2 pre-treatment group when compared with the TAA-induced group in both mice and L02 cells.Conclusions:The data suggested that AGK2 pre-treatment had hepatoprotective role in TAA-induced ALF via upregulating the expression of MFN2 and then inhibiting PERK and ferroptosis pathway in ALF.

Early systemic anticoagulation reduces hospital readmission in acute necrotizing pancreatitis patients:A retrospective cohort study

Background:Early systemic anticoagulation(SAC)is a common practice in acute necrotizing pancreatitis(ANP),and its impact on in-hospital clinical outcomes had been assessed.However,whether it affects long-term outcomes is unknown.This study aimed to evaluate the effect of SAC on 90-day readmission and other long-term outcomes in ANP patients.Methods:During January 2013 and December 2018,ANP patients admitted within 7 days from the onset of abdominal pain were screened.The primary outcome was 90-day readmission after discharge.Cox proportional-hazards regression model and mediation analysis were used to define the relationship between early SAC and 90-day readmission.Results:A total of 241 ANP patients were enrolled,of whom 143 received early SAC during their hospitalization and 98 did not.Patients who received early SAC experienced a lower incidence of splanchnic venous thrombosis(SVT)[risk ratio(RR)=0.40,95%CI:0.26-0.60,P<0.01]and lower 90-day readmission with an RR of 0.61(95%CI:0.41-0.91,P=0.02)than those who did not.For the quality of life,patients who received early SAC had a significantly higher score in the subscale of vitality(P=0.03)while the other subscales were all comparable between the two groups.Multivariable Cox regression model showed that early SAC was an independent protective factor for 90-day readmission after adjusting for potential confounders with a hazard ratio of 0.57(95%CI:0.34-0.96,P=0.04).Mediation analysis showed that SVT mediated 37.0%of the early SAC-90-day readmission causality.Conclusions:The application of early SAC may reduce the risk of 90-day readmission in the survivors of ANP patients,and reduced SVT incidence might be the primary contributor.

Magnetic resonance imaging of extraocular rectus muscles abnormalities in acute acquired concomitant esotropia

AIM:To investigate the difference of medial rectus(MR)and lateral rectus(LR)between acute acquired concomitant esotropia(AACE)and the healthy controls(HCs)detected by magnetic resonance imaging(MRI).METHODS:A case-control study.Eighteen subjects with AACE and eighteen HCs were enrolled.MRI scanning data were conducted in target-controlled central gaze with a 3-Tesla magnetic resonance scanner.Extraocular muscles(EOMs)were scanned in contiguous image planes 2-mm thick spanning the EOM origins to the globe equator.To form posterior partial volumes(PPVs),the LR and MR cross-sections in the image planes 8,10,12,and 14 mm posterior to the globe were summed and multiplied by the 2-mm slice thickness.The data were classified according to the right eye,left eye,dominant eye,and non-dominant eye,and the differences in mean cross-sectional area,maximum cross-sectional area,and PPVs of the MR and LR muscle in the AACE group and HCs group were compared under the above classifications respectively.RESULTS:There were no significant differences between the two groups of demographic characteristics.The mean cross-sectional area of the LR muscle was significantly greater in the AACE group than that in the HCs group in the non-dominant eyes(P=0.028).The maximum cross-sectional area of the LR muscle both in the dominant and non-dominant eye of the AACE group was significantly greater than the HCs group(P=0.009,P=0.016).For the dominant eye,the PPVs of the LR muscle were significantly greater in the AACE than that in the HCs group(P=0.013),but not in the MR muscle(P=0.698).CONCLUSION:The size and volume of muscles dominant eyes of AACE subjects change significantly to overcome binocular diplopia.The LR muscle become larger to compensate for the enhanced convergence in the AACE.

Outcomes of combined mitochondria and mesenchymal stem cellsderived exosome therapy in rat acute respiratory distress syndrome and sepsis

BACKGROUND The treatment of acute respiratory distress syndrome(ARDS)complicated by sepsis syndrome(SS)remains challenging.AIM To investigate whether combined adipose-derived mesenchymal-stem-cells(ADMSCs)-derived exosome(EXAD)and exogenous mitochondria(mitoEx)protect the lung from ARDS complicated by SS.METHODS In vitro study,including L2 cells treated with lipopolysaccharide(LPS)and in vivo study including male-adult-SD rats categorized into groups 1(sham-operated-control),2(ARDS-SS),3(ARDS-SS+EXAD),4(ARDS-SS+mitoEx),and 5(ARDS-SS+EXAD+mitoEx),were included in the present study.RESULTS In vitro study showed an abundance of mitoEx found in recipient-L2 cells,resulting in significantly higher mitochondrial-cytochrome-C,adenosine triphosphate and relative mitochondrial DNA levels(P<0.001).The protein levels of inflammation[interleukin(IL)-1β/tumor necrosis factor(TNF)-α/nuclear factor-κB/toll-like receptor(TLR)-4/matrix-metalloproteinase(MMP)-9/oxidative-stress(NOX-1/NOX-2)/apoptosis(cleaved-caspase3/cleaved-poly(ADP-ribose)polymerase)]were significantly attenuated in lipopolysaccharide(LPS)-treated L2 cells with EXAD treatment than without EXAD treatment,whereas the protein expressions of cellular junctions[occluding/β-catenin/zonula occludens(ZO)-1/E-cadherin]exhibited an opposite pattern of inflam-mation(all P<0.001).Animals were euthanized by 72 h post-48 h-ARDS induction,and lung tissues were harvested.By 72 h,flow cytometric analysis of bronchoalveolar lavage fluid demonstrated that the levels of inflam-matory cells(Ly6G+/CD14+/CD68+/CD11b/c+/myeloperoxidase+)and albumin were lowest in group 1,highest in group 2,and significantly higher in groups 3 and 4 than in group 5(all P<0.0001),whereas arterial oxygen-saturation(SaO2%)displayed an opposite pattern of albumin among the groups.Histopathological findings of lung injury/fibrosis area and inflammatory/DNA-damaged markers(CD68+/γ-H2AX)displayed an identical pattern of SaO2%among the groups(all P<0.0001).The protein expressions of inflammatory(TLR-4/MMP-9/IL-1β/TNF-α)/oxidative stress(NOX-1/NOX-2/p22phox/oxidized protein)/mitochondrial-damaged(cytosolic-cytochrome-C/dynamin-related protein 1)/autophagic(beclin-1/Atg-5/ratio of LC3B-II/LC3B-I)biomarkers exhibited a similar manner,whereas antioxidants[nuclear respiratory factor(Nrf)-1/Nrf-2]/cellular junctions(ZO-1/E-cadherin)/mitochondrial electron transport chain(complex I-V)exhibited an opposite manner of albumin among the groups(all P<0.0001).CONCLUSION Combined EXAD-mitoEx therapy was better than merely one for protecting the lung against ARDS-SS induced injury.

Inflammation: Complexity and significance of cellular and molecular responses

Inflammation is a multifaceted cellular and molecular response triggered by injury,infection,or various pathological conditions.Serving as a protective defense mechanism,the inflammatory response involves clinical signs like redness,swelling,pain,and increased body temperature.Immune cells,notably neutrophils and macrophages,play key roles in orchestrating this response.The delicate balance between proinflammatory and anti-inflammatory mediators,including cytokines and chemokines,regulates the inflammatory cascade.While acute inflammation is crucial for tissue repair,chronic inflammation may indicate an imbalance,contributing to conditions like autoimmune diseases.Understanding these mechanisms is vital for developing therapeutic strategies and managing chronic diseases.

Novel insights in phosphodiesterase 4 subtype inhibition to target neuroinflammation and stimulate remyelination

In neurodegenerative and classically demyelinating disorders such as multiple sclerosis(MS),spinal cord injury(SCI),stroke,and Charcot-Marie-Tooth disease,glial functioning is compromised and nervous tissue integrity is lost.Recently,primary neurodegenerative disorders such as Alzheimer’s disease,amyotrophic lateral sclerosis(ALS),and Parkinson’s disease(PD)are increasingly linked to impaired oligodendroglia functioning upon neurodegeneration.Due to the destructive micro-environment created by nervous tissue damage,the progressive cellular loss in these disorders,and the amitotic nature of neurons,spontaneous endogenous repair process are limited in nature.Hence,there is a medical need for efficient therapeutic strategies capable of supporting neuro-reparative processes to occur,likely supported by improved oligodendroglia cell functioning.

The miR-9-5p/CXCL11 pathway is a key target of hydrogen sulfide-mediated inhibition of neuroinflammation in hypoxic ischemic brain injury

We previously showed that hydrogen sulfide(H2S)has a neuroprotective effect in the context of hypoxic ischemic brain injury in neonatal mice.However,the precise mechanism underlying the role of H2S in this situation remains unclear.In this study,we used a neonatal mouse model of hypoxic ischemic brain injury and a lipopolysaccharide-stimulated BV2 cell model and found that treatment with L-cysteine,a H2S precursor,attenuated the cerebral infarction and cerebral atrophy induced by hypoxia and ischemia and increased the expression of miR-9-5p and cystathionineβsynthase(a major H2S synthetase in the brain)in the prefrontal cortex.We also found that an miR-9-5p inhibitor blocked the expression of cystathionineβsynthase in the prefrontal cortex in mice with brain injury caused by hypoxia and ischemia.Furthermore,miR-9-5p overexpression increased cystathionine-β-synthase and H2S expression in the injured prefrontal cortex of mice with hypoxic ischemic brain injury.L-cysteine decreased the expression of CXCL11,an miR-9-5p target gene,in the prefrontal cortex of the mouse model and in lipopolysaccharide-stimulated BV-2 cells and increased the levels of proinflammatory cytokines BNIP3,FSTL1,SOCS2 and SOCS5,while treatment with an miR-9-5p inhibitor reversed these changes.These findings suggest that H2S can reduce neuroinflammation in a neonatal mouse model of hypoxic ischemic brain injury through regulating the miR-9-5p/CXCL11 axis and restoringβ-synthase expression,thereby playing a role in reducing neuroinflammation in hypoxic ischemic brain injury.

Monomeric C-reactive protein:a link between chronic inflammation and neurodegeneration?

Pre-diabetic insulin resistance is associated with sub-clinical inflammation and concomitant increase in systemic C-reactive protein(CRP)levels.Type 2 diabetes mellitus(T2DM)patients register even higher chronic levels of inflammation,with excess circulating CRP originating from both typical hepatic synthesis,and also visceral white adipose tissue.

Advanced brain organoids for neuroinflammation disease modeling

Brain organoids mimic closely the embryonic human brain:Over the last decade,the development of human organoid systems has evolved rapidly.Different tissues have been modeled with organoids,such as the gut,lung,liver,kidney retina and brain.These systems have a high cellular heterogeneity,with many cell types integrated into the same system.Organoids'cellular populations interact between and amongst each other in a cellular and molecular level,which represents an advantage with respects to monolayer 2D cell culture systems.

Neuroinflammation attenuation effects by celastrol and PDIA3 in the amygdala, hippocampus and dorsal raphe nucleus of obese mice

Nowadays,roughly 603.7 million people are bothered by obesity[1].More seriously,obesity brings inflammation to the peripheral and central nervous system,which compromises the comorbidity of obesity,major depression[2],and cognitive deficits[3].Drug competent in the comorbidity is still lacking.In 2015,Liu et al.[4]reported celastrol(CEL)as a powerful anti-obesity agent.In our previous study.
