Generation of chimeric forms of rhesus macaque rhadinovirus expressing KSHV envelope glycoproteins gH and gL for utilization in an NHP model of infection

Article

作者: Li, Helen ; Wong, Scott W. ; Axthelm, Michael K. ; Govindan, Aparna N. ; McDonald, Kaidlyn A. ; Estep, Ryan D.

ABSTRACT:

Kaposi’s sarcoma-associated herpesvirus (KSHV) is a human gammaherpesvirus associated with Kaposi’s sarcoma and B cell malignancies. Like all herpesviruses, KSHV contains conserved envelope glycoproteins (gps) involved in virus binding, entry, assembly, and release from infected cells, which are also targets of the immune response. Due to the lack of a reproducible animal model of KSHV infection, the precise functions of the KSHV gps during infection in vivo are not completely known. Fortunately, a nonhuman primate (NHP) model of KSHV infection and disease has been established utilizing closely related rhesus macaque rhadinovirus (RRV) that naturally infects rhesus macaques (RM) and possesses analogous gps to KSHV. To address the roles conserved envelope gps gH and gL play during KSHV infection in vivo , we utilized the pathogenic RRV 17577 BAC to generate chimeric forms of RRV expressing KSHV gL or KSHV gH/gL, as well as an RRV mutant lacking gL expression. These viruses incorporate KSHV gH and gL into infectious virions, and although they display variable replication and differing plaque phenotypes in primary rhesus fibroblasts, they retain the ability to infect human B cells in vitro . Importantly, we also demonstrate that RRV gp chimeras can infect RM and induce the development of antibodies against KSHV. Overall, this work demonstrates that RRV gp chimeras can serve as important tools to assess the role of KSHV gH/gL in infection and disease while also providing an NHP model for testing the efficacy of KSHV gH and gL neutralizing antibodies and vaccine strategies to prevent and treat KSHV infection.

IMPORTANCE:

Rhesus macaque rhadinovirus (RRV) is a rhesus macaque homolog of KSHV and serves as a model system for examining Kaposi’s sarcoma-associated herpesvirus (KSHV) infection and pathogenesis in vivo . KSHV and RRV both encode conserved herpesvirus envelope glycoproteins, including gH and gL, that are important for regulating entry into host cells. In this study, we utilized the RRV BAC system to generate chimeric forms of RRV expressing KSHV gH and gL, as well as a mutant form of RRV lacking gL expression. Although these mutant and chimeric viruses can replicate in vitro , they do display growth properties different from wild-type RRV. Importantly, we demonstrate that RRV gp chimeras are capable of infecting rhesus macaques in vivo , inducing B cell hyperplasia, and promoting the development of anti-viral antibody responses that can also recognize KSHV antigens. RRV gp chimeras provide a novel system that allows for the examination of the role of KSHV gH and gL during infection in vivo .

Type I interferon signaling in dendritic cells limits direct antigen presentation and CD8 ⁺ T cell responses against an arthritogenic alphavirus

Article

作者: Liu, Tian-Tian ; Wagoner, Ngan ; Handley, Scott A. ; Bullock, Christopher B. ; Diamond, Michael S. ; Ohara, Ray A. ; Murphy, Kenneth M. ; Desai, Pritesh ; Wang, Leran ; Peters, Bjoern ; Ware, Brian C. ; Morrison, Thomas E.

ABSTRACT:

Ross River virus (RRV) and other alphaviruses cause chronic musculoskeletal syndromes that are associated with viral persistence, which suggests deficits in immune clearance mechanisms, including CD8 + T-cell responses. Here, we used a recombinant RRV-gp33 that expresses the immunodominant CD8 + T-cell epitope of lymphocytic choriomeningitis virus (LCMV) to directly compare responses with a virus, LCMV, that strongly induces antiviral CD8 + T cells. After footpad injection, we detected fewer gp33-specific CD8 + T cells in the draining lymph node (DLN) after RRV-gp33 than LCMV infection, despite similar viral RNA levels in the foot. However, less RRV RNA was detected in the DLN compared to LCMV, with RRV localizing principally to the subcapsular region and LCMV to the paracortical T-cell zones. Single-cell RNA-sequencing analysis of adoptively transferred gp33-specific transgenic CD8 + T cells showed rapid differentiation into effector cells after LCMV but not RRV infection. This defect in RRV-specific CD8 + T effector cell maturation was corrected by local blockade of type I interferon (IFN) signaling, which also resulted in increased RRV infection in the DLN. Studies in Wdfy4−/− , CD11c-Cre B2mfl/fl , or Xcr1-Cre Ifnar1fl/fl mice that respectively lack cross-presenting capacity, MHC-I antigen presentation by dendritic cells (DCs), or type I IFN signaling in the DC1 subset show that RRV-specific CD8 + T-cell responses can be improved by enhanced direct antigen presentation by DCs. Overall, our experiments suggest that antiviral type I IFN signaling in DCs limits direct alphavirus infection and antigen presentation, which likely delays CD8 + T-cell responses.

IMPORTANCE:

Chronic arthritis and musculoskeletal disease are common outcomes of infections caused by arthritogenic alphaviruses, including Ross River virus (RRV), due to incomplete virus clearance. Unlike other viral infections that are efficiently cleared by cytotoxic CD8 + T cells, RRV infection is surprisingly unaffected by CD8 + T cells as mice lacking or having these cells show similar viral persistence in joint and lymphoid tissues. To elucidate the basis for this deficient response, we measured the RRV-specific CD8 + T-cell population size and activation state relative to another virus known to elicit a strong T-cell response. Our findings reveal that RRV induces fewer CD8 + T cells due to limited infection of immune cells in the draining lymph node. By increasing RRV susceptibility in antigen-presenting cells, we elicited a robust CD8 + T-cell response. These results highlight antigen availability and virus tropism as possible targets for intervention against RRV immune evasion and persistence.

Interferon regulatory factor 8-driven reprogramming of the immune microenvironment enhances antitumor adaptive immunity and reduces immunosuppression in murine glioblastoma

Article

作者: Collins, Sara A ; Nejo, Takahide ; Kasahara, Noriyuki ; Chuntova, Pavlina ; Patel, Trishna S ; Yamamichi, Akane ; Montoya, Megan ; Okada, Hideho

Abstract:

Background:

Glioblastoma (GBM) has a highly immunosuppressive tumor immune microenvironment (TIME), largely mediated by myeloid-derived suppressor cells (MDSCs). Here, we utilized a retroviral replicating vector (RRV) to deliver Interferon Regulatory Factor 8 (IRF8), a master regulator of type 1 conventional dendritic cell (cDC1) development, in a syngeneic murine GBM model. We hypothesized that RRV-mediated delivery of IRF8 could “reprogram” intratumoral MDSCs into antigen-presenting cells and thereby restore T-cell responses.

Methods:

Effects of RRV-IRF8 on survival and tumor growth kinetics were examined in the SB28 murine GBM model. The immunophenotype was analyzed by flow cytometry and gene expression assays. We assayed functional immunosuppression and antigen presentation by ex vivo T-cell-myeloid co-culture.

Results:

Intratumoral injection of RRV-IRF8 in mice bearing intracerebral SB28 glioma significantly suppressed tumor growth and prolonged survival. RRV-IRF8 treated tumors exhibited significant enrichment of cDC1s and CD8+ T-cells. Additionally, myeloid cells derived from RRV-IRF8 tumors showed decreased expression of the immunosuppressive markers Arg1 and IDO1 and demonstrated reduced suppression of naïve T-cell proliferation in ex vivo co-culture, compared to controls. Furthermore, DCs from RRV-IRF8 tumors showed increased antigen presentation compared to those from control tumors. In vivo treatment with azidothymidine (AZT), a viral replication inhibitor, showed that IRF8 transduction in both tumor and non-tumor cells is necessary for survival benefit, associated with a reprogrammed, cDC1- and CD8 T-cell-enriched TIME.

Conclusions:

Our results indicate that reprogramming of glioma-infiltrating myeloid cells by in vivo expression of IRF8 may reduce immunosuppression and enhance antigen presentation, achieving improved tumor control.

索元生物在研脑瘤基因疗法临床首位受试者完成入组

▎药明康德内容团队报道 3月24日，索元生物宣布其创新药DB107治疗新诊断的高级别胶质瘤的临床1/2期试验首例受试者完成入组。这项名为“评估DB107 RRV疗效的1/2a期研究，在切除时和术后静脉注射，联合DB107FC和放射治疗或DB107FC、替莫唑胺 (TMZ) 和放射治疗对新诊断的高级别胶质瘤患者进行治疗”的临床试验是由三家著名脑瘤研究机构，加州大学旧金山医学院、南加州大学及加州大学圣地亚哥医学院共同发起。该试验计划招募70名患者，其目标是证明DB107在生物标志物阳性脑瘤患者中无进展生存率的改善。 DB107为一种组合疗法，即由前药激活剂基因疗法的逆转录病毒复制载体（RRV） DB107-RRV（vocimagene amiretrorepvec）和口服前药DB107-FC（缓释5-氟胞嘧啶）两部分组成。DB107-RRV是一种肿瘤内和静脉注射的逆转录病毒复制载体（RRV），可将口服的5FC在肿瘤部位转化为强效化疗药5-氟尿嘧啶（5-FU）。这一疗法可使瘤内浓度达到5-FU全身用药的30-50倍，在杀死局部细胞的同时，最大限度地减少了全身暴露和5-FU的脱靶毒性。通过过往临床试验的回顾性研究，索元生物利用其独特的DGM生物标志物发现平台，发现了一个全新的生物标志物Denovo Genomic Marker 7（DGM7）。DGM7阳性的患者的总体生存率显著优于DGM7阴性患者，同时也显著优于采用标准治疗的患者。加州大学旧金山医学院神经肿瘤学家兼首席研究员Nicholas Butowski博士说：“招募第一批患者是推进高级胶质瘤患者治疗选择的重要里程碑。我们认为这项试验将为患者及提高新诊断患者的生存率提供有高度的价值。” 该项目合作单位Anova CEO Chris Beardmore博士说：“这是一项革命性的科学研究，治疗方法藉由基因疗法感染癌症细胞进行化疗。因此可以显著降低化疗治疗常见的全身毒性并且进一步感染无法通过手术和其他干预措施去除的癌细胞，大幅改善脑瘤患者的病症。” 索元生物创始人暨董事长罗文博士表示：“高级别胶质瘤（High-grade gliomas, HGG）仍然是治疗最具挑战性的癌症之一，其治疗选择有限且病情高度复杂。该疾病的治疗方法在过去20年中几乎没有变化。DGM7则是DGM发现平台首次在基因治疗药物中发现的全新生物标志物，是索元生物DGM平台在小分子药物之外的成功案例，再次证明了DGM平台的可持续性和可扩展性。这个项目将精准医疗、基因治疗及化药有机的结合起来，这种组合疗法旨在根除肿瘤细胞，同时以最小的毒性刺激强大而持久的抗癌免疫反应。” 参考资料： [1]索元生物新闻稿. 本文由药明康德内容团队根据公开资料整理编辑，欢迎个人转发至朋友圈。转发授权及其他合作需求，请联系wuxi_media@wuxiapptec.com。免责声明：药明康德内容团队专注介绍全球生物医药健康研究进展。本文仅作信息交流之目的，文中观点不代表药明康德立场，亦不代表药明康德支持或反对文中观点。本文也不是治疗方案推荐。如需获得治疗方案指导，请前往正规医院就诊。

Anova Announces First Patient Enrolled to Phase 1/2a Study of DB107 for the Treatment of High-Grade Gliomas

LONDON, UK & CHICAGO, IL, USA I March 05, 2025 I Anova Enterprises, Inc. (Anova), a technology-enabled CRO dedicated to accelerating promising treatments, has announced enrollment of the first two patients in the highly anticipated study of DB107 for the treatment of brain tumors. The Phase 1/2a clinical trial is a multicenter, open-label study designed to confirm whether treatment DB107, when added to standard-of-care (SOC), provides clinical benefit to patients with newly diagnosed high-grade gliomas (HGG) when compared to historical performance. The study is funded with a California Institute for Regenerative Medicine (CIRM) grant to advance the development of DB107 in patients with newly diagnosed high-grade glioma. Led by Noriyuki Kasahara, MD, PhD, Principal Investigator, Brain Tumor Research Center (BTRC) at University of California, San Francisco (UCSF), the study is also enrolling at the University of Southern California (USC) and the University of California at San Diego UCSD, and will enroll 70 participants over the coming months. “Enrolling our first patients is an important milestone in our mission to advance treatment options for patients with high- grade glioma,” said Nicholas Butowski, MD, Neuro-Oncologist and Lead Investigator at UCSF. “We are optimistic this trial will provide valuable insights into how we can better treat patients and improve survival in newly diagnosed patients.” High- grade gliomas remain one of the most challenging cancers to treat, with limited treatment options and a high degree of complexity. Treatment for the disease has not changed in 20 years. DB107 is an investigational gene therapy being developed by Denovo Biopharma for the treatment of HGG, including glioblastoma multiforme (GBM). It comprises two components: DB107-RRV (vocimagene amiretrorepvec), a retroviral replicating vector designed to selectively infect and change cancer cells, and DB107-FC, an extended-release oral formulation of 5-fluorocytosine (5-FC), which is converted into a chemotherapeutic agent within the tumor. This combination aims to eradicate tumor cells while stimulating a robust and durable anti-cancer immune response with minimal toxicity. Chris Beardmore said, “This is revolutionary science where the treatment infects cancer cells and genetically changes them to make chemotherapy inside of the infected cells. This is known to reduce systemic toxicity commonly seen with systemic treatments. It also has a chance to infect cells that cannot be removed by surgery and other interventions to improve outcomes in newly diagnosed brain tumor patients.” The clinical trial is currently recruiting eligible patients who meet the study criteria at UCSF, USC and UCSD. Individuals interested in participating or learning more about the trial can contact the study team at info.us@anovaevidence.com . To find out more, contact info.us@anovaevidence.com .

Denovo recently announced a major breakthrough in treatment‑resistant depression (TRD) with its DGM4™ biomarker‑guided DB104 drug (liafensine, a potential first‑in‑class triple reuptake inhibitor for TRD). The global Phase 2b clinical trial of DB104 in DGM4‑positive patients with TRD demonstrated strikingly positive results, with highly significant improvements in symptoms of depression seen in DGM4‑positive patients.

About the California Institute for Regenerative Medicine (CIRM) The California Institute for Regenerative Medicine (CIRM) is a funding agency established by Californians to accelerate regenerative medicine research to deliver treatments for patients with unmet medical needs. Established in 2004 through the passage of Proposition 71, CIRM was initially funded with $3 billion from the state of California to support ongoing research, and in 2020, was funded again with another $5.5 billion through Proposition 14 to continue the Agency’s important work. CIRM has provided billions in funding to support stem cell, genetic research, and development programs in its portfolio. Through the Agency’s research, infrastructure, and education programs, CIRM aims to transform the field of regenerative medicine, stimulate economic growth, and improve the lives of diverse communities throughout the state.
