Next-Generation Immunotherapies: Engineering Stem Cells into Functional Immune Effectors

About this Research Topic

Background

Adoptive immune cell therapies, such as CAR-T and NK cell therapies, have demonstrated remarkable success in certain hematologic malignancies but face limitations in scalability, donor dependence, and restricted efficacy against solid tumors. Stem cells, including induced pluripotent stem cells (iPSCs), embryonic stem cells (ESCs), and mesenchymal stromal/stem cells (MSCs), offer a renewable, genetically modifiable source for generating standardized and potent immune effectors. Recent advances in differentiation protocols, genetic engineering, and synthetic biology now allow for precise reprogramming of stem cells into tailored immune cell subsets with enhanced persistence, tumor homing capacity, and resistance to immunosuppression. This rapidly emerging field holds promise for delivering next-generation, off-the-shelf cancer immunotherapies that would address unmet clinical needs and overcome the bottlenecks of current adoptive cell and gene therapy approaches.

The goal of this Research Topic is to feature cutting-edge advances at the intersection of stem cell biology/engineering and cancer immunotherapy. The central challenge in this field is to develop scalable, programmable, and clinically safe immune effector cells from renewable stem cell sources. Recent breakthroughs in genome editing, synthetic biology, and biomaterials enable us an unprecedented manipulation of stem cell fate that can be used for generation of cytotoxic cells with enhanced persistence, trafficking, and tumor-killing capabilities. By integrating knowledge from differentiation biology, tumor immunology, and translational oncology, this collection aims to showcase approaches to achieve greater in vivo persistence, increased tumor cell killing and infiltration of solid tumors, and the capacity to counter or modify the immunosuppressive tumor microenvironment (TME). Through multidisciplinary contributions, the collection aims to provide a consolidated knowledge base for rational design and (pre)clinical development of engineered immune effectors for both solid and hematologic malignancies, thereby paving the way toward novel cancer immunotherapies.

This Research Topic invites original research, reviews, mini-reviews, perspectives, and methodology reports focused on strategies to engineer stem cells into functional immune effector cells for cancer therapy. We welcome studies on generating engineered pluripotent or adult stem cells to gain specific or hybrid immune characteristics. Contributions may explore the application of synthetic biology tools, such as chimeric antigen receptors (CARs), T cell receptor (TCR) engineering, cytokine expression, immune checkpoint modulation, expression of killer ligands (e.g. TRAIL), and chemokines and their receptors in order to enhance the specificity and potency of these cells. Submissions addressing the optimization of differentiation protocols, enhancement of functional fitness, solutions to TME-mediated suppression, and functional comparisons with peripheral blood-derived immune cells are encouraged. We also invite insights into large-scale, GMP-compliant manufacturing, safety, and regulatory pathways toward clinical translation.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
