Targeting multiple immune mechanisms may overcome therapy resistance and further improve cancer immunotherapy for humans.Here,we describe the application of virus-like vesicles(VLV)for delivery of three immunomodulators alone and in combination,as a promising approach for cancer immunotherapy.VLV vectors were designed to deliver single chain interleukin(IL)-12,shorthairpin RNA(shRNA)targeting programmed death ligand 1(PD-L1),and a dominant-negative form of IL-17 receptor A(dn-IL17RA)as a single payload or as a combination payload.Intralesional delivery of the VLV vector expressing IL-12 alone,as well as the trivalent vector(designated CARG-2020)eradicated large established tumors.However,only CARG-2020 prevented tumor recurrence and provided long-term survival benefit to the tumor-bearing mice,indicating a benefit of the combined immunomodulation.The abscopal effects of CARG-2020 on the non-injected contralateral tumors,as well as protection from the tumor cell re-challenge,suggest immune-mediated mechanism of protection and establishment of immunological memory.Mechanistically,CARG-2020 potently activates Th1 immune mechanisms and inhibits expression of genes related to T cell exhaustion and cancer-promoting inflammation.The ability of CARG-2020 to prevent tumor recurrence and to provide survival benefit makes it a promising candidate for its development for human cancer immunotherapy.

Chinese Medical Journal 2022年第10期135卷 1234-1241页

作者： Babusai Rapaka Daniel B.Maselli Gontrand Lopez-Nava Inmaculada Bautista-Castano Reem Matar Veeravich Jaruvongvanich Eric J.Vargas Andrew C.Storm Andres Acosta Barham K.Abu Dayyeh Division of Gastroenterology and Hepatology Mayo ClinicRochesterMN 55905USA Madrid Sanchinarro University Hospital MadridSpain

Background: Endoscopic bariatric therapies can help address widening management gaps in obesity. Their ability to facilitate weight loss is largely tied to influences on appetite through perturbations of gastric emptying and accommodation. As these tools gain traction in obesity therapy, their physiologic underpinnings require exploration, which may enhance efficacy, tolerance, and patient-tailored care.Methods: We prospectively assessed consecutive subjects with fluid-filled intragastric balloons (IGBs) (n = 18) placed between October 2016 and June 2017 or underwent endoscopic sleeve gastroplasty (ESG) (n = 23) from March 2018 to June 2018. Patients underwent physiologic appraisal at 3 months with13C-spirulina-based gastric emptying breath test to determine time to half emptying (T50), as well as maximum tolerated volume (MTV) of a standard nutrient drink test. Changes in T50 and MTV at 3 months were compared with percent total body weight loss (%TBWL) at 3 and 6 months using best-fit linear regression.Results: The change in T50 at 3 months correlated with %TBWL at 3 months for IGB (P = 0.01) and ESG (P = 0.01) but with greater impact on %TBWL in IGB compared to ESG (R2 = 0.42vs. 0.26). Change in T50 at 3 months was predictive of weight loss at 6 months for IGB (P = 0.01) but not ESG (P = 0.11). ESG was associated with greater decrease in MTV compared to IGB (340.25 ± 297.97 mLvs. 183.00 ± 217.13 mL,P = 0.08), indicting an enhanced effect on satiation through decreased gastric accommodation. Changes in MTV at 3 months did not correlate with %TBWL for either IGB (P = 0.26) or ESG (P = 0.49) but trended toward significance for predicting %TBWL at 6 months for ESG (P = 0.06) but not IGB (P = 0.19).Conclusion: IGB and ESG both induce weight loss but likely through distinct gastric motor function phenotypes, and gastric emptying may predict future weight loss in patients with IGB.

Lipolysis supports bone formation by providing osteoblasts with endogenous fatty acid substrates to maintain bioenergetic status

Bone Research 2023年第4期11卷 876-894页

Bone formation is a highly energy-demanding process that can be impacted by metabolic disorders.Glucose has been considered the principal substrate for osteoblasts,although fatty acids are also important for osteoblast function.Here,we report that osteoblasts can derive energy from endogenous fatty acids stored in lipid droplets via lipolysis and that this process is critical for bone formation.As such,we demonstrate that osteoblasts accumulate lipid droplets that are highly dynamic and provide the molecular mechanism by which they serve as a fuel source for energy generation during osteoblast maturation.Inhibiting cytoplasmic lipolysis leads to both an increase in lipid droplet size in osteoblasts and an impairment in osteoblast function.The fatty acids released by lipolysis from these lipid droplets become critical for cellular energy production as cellular energetics shifts towards oxidative phosphorylation during nutrient-depleted conditions.In vivo,conditional deletion of the ATGL-encoding gene Pnpla2 in osteoblast progenitor cells reduces cortical and trabecular bone parameters and alters skeletal lipid metabolism.Collectively,our data demonstrate that osteoblasts store fatty acids in the form of lipid droplets,which are released via lipolysis to support cellular bioenergetic status when nutrients are limited.Perturbations in this process result in impairment of bone formation,specifically reducing ATP production and overall osteoblast function.

Nephrolithiasis is a common,painful condition that requires surgery in many patients whose stones do not pass spontaneously.Recent technologic advances have enabled the use of ultrasonic propulsion to reposition stones within the urinary tract,either to relieve symptoms or facilitate treatment.Burst wave lithotripsy(BWL)has emerged as a noninvasive technique to fragment stones in awake patients without significant pain or renal injury.We review the preclinical and human studies that have explored the use of these two technologies.We envision that BWL will fill an unmet need for the noninvasive treatment of patients with nephrolithiasis.

作者： Craig E.Pfeifer Leanna M.Ross Samantha R.Weber Xuemei Sui Steven N.Blair Department of Exercise Science University of South Carolina921 Assembly StColumbiaSC29208United States Applied Sport and Exercise Sciences University of GloucestershireUniversity of Gloucestershire Oxstalls CampusOxstalls LnLonglevens GL29HWUnited Kingdom Duke Molecular Physiology Institute Duke University School of Medicine300 N Duke StDurhamNC27701United States Department of Nursing and Health Sciences Limestone University1115 College DrGaffneySC29340United States

This retrospective cohort study examined the relationship between self-reported participation in flexibility and muscular strengthening activities and the development of functional limitation(i.e.,once an individual has difficulty with or becomes unable to perform activities of daily living).Data were obtained from 1318 adults(mean age 49.59.7 years;98.7%Caucasian;14.9%female)enrolled in the Aerobics Center Longitudinal Study from 1979 to 2004 and free of functional limitation at baseline.Mail-back health surveys were used to prospectively determine incident functional limitation.Participation in muscle-strengthening and flexibility activities was assessed via self-report.Adjusted logistic regression analyses were used to determine the odds ratios(OR)and corresponding 95%confidence intervals for developing functional limitation during follow-up based on participation in general and specific categories of flexibility(‘Stretching’,‘Calisthenics’,or‘Exercise Class’)and musclestrengthening activities(‘Calisthenics’,‘Free Weights’,‘Weight Training Machines’,or‘Other’).Overall,42.6%of the sample reported incident functional limitation.After adjusting for potential confounders(e.g.,age,sex,cardiometabolic risk factors),those who reported performing muscle-strengthening activities in general(n=685)were at lower risk of developing functional limitation[OR=0.79(0.63–1.00)].In addition,the specific flexibility activities of stretching(n=491)and calisthenics(n=122)were associated with 24%and 38%decreased odds of incident functional limitation,respectively.General muscle-strengthening,stretching,and calisthenics activities are prospectively associated with decreased risk of incident functional limitation in generally healthy,middleaged and older adults.Thus,both public health and rehabilitation programs should highlight the importance of flexibility and muscle-strengthening activities during adulthood to help preserve functional capacity.

BACKGROUND The increased prevalence of inflammatory bowel disease(IBD)among patients with obesity and type 2 diabetes suggests a causal link between these diseases,potentially involving the effect of hyperglycemia to disrupt intestinal barrier integrity.AIM To investigate whether the deleterious impact of diabetes on the intestinal barrier is associated with increased IBD severity in a murine model of colitis in mice with and without diet-induced obesity.METHODS Mice were fed chow or a high-fat diet and subsequently received streptozotocin to induce diabetic-range hyperglycemia.Six weeks later,dextran sodium sulfate was given to induce colitis.In select experiments,a subset of diabetic mice was treated with the antidiabetic drug dapagliflozin prior to colitis onset.Endpoints included both clinical and histological measures of colitis activity as well as histochemical markers of colonic epithelial barrier integrity.RESULTS In mice given a high-fat diet,but not chow-fed animals,diabetes was associated with significantly increased clinical colitis activity and histopathologic markers of disease severity.Diabetes was also associated with a decrease in key components that regulate colonic epithelial barrier integrity(colonic mucin layer content and epithelial tight junction proteins)in diet-induced obese mice.Each of these effects of diabetes in diet-induced obese mice was ameliorated by restoring normoglycemia.CONCLUSION In obese mice,diabetes worsened clinical and pathologic outcomes of colitis via mechanisms that are reversible with treatment of hyperglycemia.Hyperglycemia-induced intestinal barrier dysfunction offers a plausible mechanism linking diabetes to increased colitis severity.These findings suggest that effective diabetes management may decrease the clinical severity of IBD.

Selective deletion of the soluble Colony-Stimulating Factor 1 isoform in vivo prevents estrogen-deficiency bone loss in mice

Neutralizing CSF1 in vivo completely prevents ovariectomy （OVX）-induced bone loss in mice. There are two isoforms of CSF1, soluble （sCSF1）, and membrane-bound （mCSF1）, but their individual biological functions are unclear. It had been previously reported that mCSF1 knockout （K/O） and wild type （Wt） female mice experience the same degree of bone loss following OVX. In Wt mice the expression of sCSF1 was elevated fourfold in skeletal tissue following OVX while expression of mCSF1 was unchanged. To examine the role of sCSF1 in OVX-induced bone loss, mice were engineered in which sCSF1 was not expressed but expression of mCSF1 was unaffected （sCSF1 K/O）. Isoform-specific reverse transcription PCR confirmed the absence of transcripts for sCSF1 in bone tissue isolated from these animals and no circulating CSF1 was detected by ELISA. Surprisingly, there were no significant differences in bone mineral density （BMD） between sCSF1 K/O mice and Wt controls as assessed by dual-energy X-ray absorptiometry and micro-CT. However, one month after OVX, femoral, spinal and total BMD had declined by 11.2%, 8.9%, and 8.7% respectively in OVX-Wt animals as compared to Sham-OVX. In contrast OVX sCSF1 K/O mice showed changes of ＋0.1%, - 2.4%, and ＋2.3% at the same 3 sites compared to Sham-OVX sCSF1 K/O mice. These data indicate important non-redundant functions for the two isoforms of CSF1 and suggest that sCSF1, but not mCSF1, plays a key role in estrogen-deficiency bone loss.

Unexpected alliance between syndecan-1 and innatelike T cells to protect host from autoimmune effects of interleukin-17

引用

World Journal of Diabetes 2018年第12期9卷 220-225页

作者： Anil Kumar Jaiswal Mohanraj Sadasivam Abdel Rahim A Hamad Department of Pathobiology Auburn University Department of Pathology School of Medicine Johns Hopkins University

Innate-like T cells, namely natural killer T(NKT) and γδ T cells, play critical roles in linking innate and adaptive immune responses through rapid production of cytokines. Prominent among these cytokines is interleukin-17(IL-17), which is a potent proinflammatory cytokine that plays a critical role in host defense against fungi and extracellular bacteria. However, excessive IL-17-production promotes autoimmune diseases, including psoriasis, multiple sclerosis, rheumatoid arthritis, inflammatory bowel disease, and systemic lupus erythematosus. IL-17 has also been implicated in regulating body fat, which is highly relevant given rises in obesity and type 2 diabetes. NKT cells, γδ T cells and mucosal-associated invariant T cells(MAIT) are the major sources of IL-17 involved in protection of mucosal surfaces from opportunistic infections and causing autoimmunity when become dysregulated. Given the pathogenic effects of IL-17, efforts have been directed towards understanding mechanisms that guard against IL-17 overproduction. One novel potent mechanism is mediated by the heparan sulfate proteoglycan, syndecan-1(sdc1), which is selectively expressed by IL-17-producing subsets of NKT and γδ T cells. This unexpected role for sdc1 is uncovered by analysis of NKT and γδ T cells in sdc1-deficient mice. In this mini-review, we discuss selective expression of sdc1 by these innate T cells and consequences of its absence on IL-17 homeostasis and pathological implications.
