Zika virus infection during pregnancy is associated with severe birth defects including microcephaly in the new born. The lack of specific treatment calls for the development of a safe and effective vaccine for use in pregnant women. We recently tested the efficacy of a Virus Like Particle (VLP) vaccine for Zika virus in mice and found that Capsid-preMembrane-Env (CprME) VLPs generated a better neutralizing antibody response than preMembrane-Env (prME) VLPs. The superiority of CprME VLPs suggested that inclusion of capsid in the vaccine may enhance the immune response. However, production of CprME VLPs requires co-expression of NS2B-3 protease, which creates a major hurdle for generation of stable cell lines. To overcome this limitation, we generated a bicistronic vector that expresses CprME and NS2B-3 using an IRES sequence. This bicistronic expression cassette, in a lentiviral vector, was used to create a stable cell line that constitutively secretes CprME VLPs. The expression of NS2B-3, presence of capsid in the secreted VLPs, efficiency of VLP release, and stability of the cell line was extensively tested. Antigen sparing studies in mice using prME and CprME VLPs, both derived from stable cell lines, confirmed the superiority of CprME VLPs in generation of neutralizing antibody response. Capsid specific antibodies were detected in CprME VLP immunized mice providing mechanistic insights into the superiority of these VLPs. Challenge of CprME VLP immunized mice with Zika PRVABC59 showed complete protection against day 3 viremia further validating the efficacy of the vaccine. Our study is the first to generate a stable cell line secreting Zika CprME VLPs via natural NS2B-3 cleavage, demonstrate incorporation of capsid in CprME VLPs and complete protection in challenge studies. This is a major advancement for the Zika vaccine platform that is safe for use in pregnant women and readily scalable for use in developing countries.

Enhancement of Anti-Leukemia Immunity by Leukemia–Derived Exosomes Via Downregulation of TGF-β1 Expression

Article

作者: Hu, Weiwei ; Wan, Jiangbo ; Hao, Siguo ; Huang, Fang

Background/Aims: Minimal residual leukemia cells (MRLs) are difficult to eradicate through traditional treatment and therefore remain to be a major threat to the long-term survival of leukemia patients. Tumor-derived exosomes (TEXs), which carry tumor associated antigens (TAA), may be a potential cell-free tumor vaccine for the specific eradication of MRLs. However, TEXs are intended to be less immunogenic due to exosomal TGF-β1. To further optimize the efficacy of TEX-based vaccines, we investigated whether exosomes from TGF-β1 silenced leukemia cells (LEXTGF-β1si) had an increased potential to induce a specific antitumor effect compared with non-modified exosomes. Methods: Exosomal TGF-β1 was downregulated via lentiviral shRNA silencing of TGF-β1 in leukemia cells. The characteristics of LEXTGF-β1si were determined via electron microscopy, western blot analysis, and flow cytometry. The antitumor effect of LEXTGF-β1si was evaluated by detecting the properties of LEXTGF-β1si-pulsed dendritic cells (DCs), CD4+ T-cell proliferation, Th1 cytokine secretion, specific CTL activity, and NK cell function. Moreover, to verify the superiority of LEXTGF-β1si immunization, LEXTGF-β1si was subcutaneously injected into DBA/2 mice: either followed by tumor challenge or tumor bearing. Results: The lentiviral shRNA silencing of TGF-β1 in parental leukemia cells successfully downregulated the TGF-β1 level in leukemia cell derived exosomes (LEX). LEXTGF-β1si was uptaken by DCs and was more potent in promoting DC function by upregulating the surface expression of costimulatory factors and MHC class II molecules, while inducing the secretion of IL-12p70 and TNF-α. Furthermore, immunization with LEXTGF-β1si facilitated CD4+ T-cell proliferation and Th1 cytokine secretion, and stimulated stronger specific cytotoxic lymphocyte (CTL) response and nature killer (NK) cell cytotoxicity more efficiently compared to non-modified LEX. In mice models, immunization with LEXTGF-β1si resulted in a more potent capability to inhibit tumor growth and to prolong survival, suggesting that LEXTGF-β1si was more effective in both protective and therapeutic antitumor tests than non-modified LEX. Conclusions: These data suggested that down-regulation of exosomal TGF-β1 effectively induced potent anti-tumor immunity. Our strategy of optimizing exosome vaccine may have promising potential for leukemia immunotherapy.

Immature Dendritic Cell-Derived Exosomes: a Promise Subcellular Vaccine for Autoimmunity

2区 · 医学

Review

作者: Huan Yang ; Song Ouyang ; Bo Xiao ; Yi Li ; Weifan Yin

Exosomes, 60-90-nm-sized vesicles, are produced by a large number of cell types, including tumor cells, neurons, astrocytes, hemocytes, intestinal epithelial cells, and so on. Dendritic cell (DC), the most potent professional antigen-presenting cell in the immune system, produces exosomes in the course of maturation. Mature DCs produce exosomes with the ability to elicit potent immunoactivation, resulting in tumor eradication and bacterial or virus elimination. Given the notion that exosomes are stable and easy to be modified artificially, autologous mature DC-derived exosomes have been vaccinated into patients with malignant diseases. In clinical trials utilizing exosomes as therapeutic approaches, researchers observed considerable curative effect with little side effect. However, immature or suppressive DC-derived exosomes harbor anti-inflammatory properties distinct from mature DC-derived exosomes. In murine models of autoimmune disease and transplantation, immature DC-derived exosomes reduced T cell-dependent immunoactivation, relieved clinical manifestation of autoimmune disease, and prolonged survival time of transplantation. Although the exact mechanism of how immature DC-derived exosomes function in vivo is still unclear, and there are no clinical trials regarding application of exosome vaccine into patients with autoimmune disease, we will analyze the promise of immature DC-derived exosomes as a subcellular vaccine in autoimmunity in this review.

Capricor Therapeutics Announces Positive 24-Month Results from Ongoing HOPE-2 Open Label Extension Study of CAP-1002 in Duchenne Muscular Dystrophy

-Improvements in Left Ventricular Ejection Fraction (LVEF) for the Majority of Patients Suggest Preservation of Cardiac Function- -Results in Performance of the Upper Limb PUL v2.0 Continue to Show Long-Term Benefit in Skeletal Muscle Function (p=0.02)- -Safety and Efficacy Results Continue to Suggest Potential Disease Attenuation in Duchenne Muscular Dystrophy (DMD)- -Results to be Presented at the PPMD Annual Conference Being Held Today- SAN DIEGO, June 30, 2023 (GLOBE NEWSWIRE) -- Capricor Therapeutics (NASDAQ: CAPR), a biotechnology company focused on the development of transformative cell and exosome-based therapeutics for the treatment and prevention of muscular and other select diseases, today announced positive 24-month safety and efficacy results from its ongoing HOPE-2 open label extension (OLE) study with its lead asset, CAP-1002, for the treatment of Duchenne muscular dystrophy (DMD). Data from the OLE study demonstrated that the majority of patients had an improvement in left ventricular ejection fraction (LVEF), after two years of CAP-1002 treatment, which suggests preservation of cardiac function. Additionally, patients continue to show statistically significant benefit (p=0.021) after two years of treatment in the Performance of the Upper Limb (PUL v2.0) scale when compared to the original rate of decline of the placebo group from HOPE-2 after one year. Furthermore, the OLE study continues to show a favorable safety profile for long-term treatment of CAP-1002. These data will be featured in an oral presentation being webcast today at this year’s Parent Project Muscular Dystrophy (PPMD) Annual Conference. “The results from this two-year open label study are tremendously impactful for DMD patients showing cardiac and skeletal functional benefits, which underscores the potential long-term benefits of CAP-1002 treatment in DMD,” said Linda Marbán, Ph.D., Capricor’s chief executive officer. “Importantly, the natural history of DMD cardiomyopathy suggests a steady decline in cardiac function as measured by ejection fraction, however, in HOPE-2-OLE, we observed improvements in heart function in six of nine patients. Furthermore, as the HOPE-2-OLE data highlights the disease modifying potential of CAP-1002, we believe it is imperative to start treatment as early as possible to prevent the irreversible loss of muscle. Taken together with the favorable safety/tolerability profile, these data position CAP-1002 as a potential anchor therapy for DMD patients. We thank the patients, their families, caregivers, and the broader Duchenne community for continuing to work with us on this promising therapy.” The HOPE-2-OLE study previously met its primary endpoint at the one-year timepoint on the PUL v2.0 scale (p=0.02). At the 24-month timepoint, data showed statistically significant differences in the PUL v2.0 in the OLE treatment group when compared to the original rate of decline of the placebo group from HOPE-2 after one-year (p=0.021). LVEF was measured using cardiac magnetic resonance imaging (cMRI) and six of nine patients showed improvements in heart function with CAP-1002 treatment compared to their final assessment at the end of the HOPE-2 study. Over time, there was an increasing correlation with PUL v2.0 and ejection fraction results (24-month OLE results r=0.75, p=0.02). Dr. Marbán continued, “We are encouraged by the robust and consistent results observed to date and will continue to work closely with the U.S. Food and Drug Administration (FDA) to bring CAP-1002 to patients as quickly as possible. We plan to discuss these results as well as the key features of our ongoing Phase 3 HOPE-3 trial and outline our proposed path towards submission of a potential Biologics License Application (BLA) during our upcoming meeting with the FDA. In parallel, HOPE-3 continues to enroll patients and we remain on track to complete enrollment in the second half of 2023 and report the interim analysis in the fourth quarter of 2023.” CAP-1002 treatment during the HOPE-2-OLE study continues to yield a consistent safety profile and has been well-tolerated throughout the study. The HOPE-2-OLE study remains ongoing, and participants continue to be monitored for safety and functional performance. About HOPE-2 Open Label Extension (OLE) Study HOPE-2 was a randomized, double-blind, placebo-controlled, Phase 2 clinical study of Capricor’s lead investigational therapy, CAP-1002, in boys and young men who have DMD. Study patients were treated via intravenous delivery with either CAP-1002 (150 million cells per infusion) or placebo every 3 months. Data from a total of 20 patients was analyzed (12 placebo and 8 treated) at the 12-month time-point and the results were published in The Lancet. After the completion of the HOPE-2 study, all patients stopped treatment for approximately 392 days (mean, range [239, 567]), which is referred to as the gap phase. Then all eligible patients who wished to remain on treatment re-entered the OLE study where they received CAP-1002 (150 million cells per infusion) every three months over the course of 24 months. Patients continued through the gap phase (off treatment for both groups) and the OLE phase (on treatment for both groups). About Duchenne Muscular Dystrophy Duchenne muscular dystrophy (DMD) is a devastating genetic disorder characterized by progressive weakness and chronic inflammation of the skeletal, heart and respiratory muscles. Patients suffering from DMD typically lose their ability to walk in their teenage years and generally die of cardiac or respiratory complications by age 30. It occurs in approximately one in every 3,600 live male births across all races, cultures and countries. DMD afflicts approximately 200,000 boys and young men around the world. Treatment options are limited and there is no cure. About CAP-1002 CAP-1002 consists of allogeneic cardiosphere-derived cells (CDCs), a population of stromal cells that have been shown in preclinical and clinical studies to exert potent immunomodulatory, antifibrotic and regenerative actions in dystrophinopathy and heart failure. CDCs act by secreting extracellular vesicles known as exosomes, which target macrophages and alter their expression profile so that they adopt a healing, rather than a pro-inflammatory, phenotype. CDCs have been the subject of over 100 peer-reviewed scientific publications and have been administered to over 200 human subjects across several clinical trials.
