Background

T cell therapies can lead to deep and durable responses in a range of solid tumors. This has been demonstrated for both engineered T cells, such as chimeric antigen receptor (CAR) T cells and T cell receptor (TCR) T cells, as well as non-engineered approaches such as tumor infiltrating lymphocytes (TILs) or T cells stimulated from peripheral blood. The common goal of these approaches is to direct a significant T cell response specifically to the tumor. In order to make these therapies more effective and accessible to the maximum number of patients, several key challenges need to be addressed, considering both the T cell specificity, potency and safety, as well as the complexity of the manufacturing process and the patient experience.

The goal of this Research Topic is to bring together innovations and advancements that address key scientific, technological, and clinical challenges in improving efficacy and expanding the reach of cell therapies to a broader patient population. This Research Topic seeks to cover the full spectrum of the therapeutic development pipeline, including the identification and validation of novel targets, strategies to enhance the potency and persistence of cell therapies while mitigating toxicities, assessment of potential mechanisms of cell therapy failure, and innovative approaches to overcome barriers in manufacturing scalability and accessibility.

Additionally, we invite contributions that explore novel manufacturing techniques, such as in vivo generation of cell therapies, and process engineering strategies that simplify production and increase affordability.
We also welcome submissions related to clinical experiences, including experimental trials and strategies to manage the unique toxicities associated with T-cell therapeutics. Through this interdisciplinary effort, the collection aspires to accelerate the translation of scientific breakthroughs into practical, scalable, and impactful treatments, ultimately broadening access to potentially curative therapies.

Key scientific advances:

- Identification and validation of targets, including shared antigens or personalized neoantigens, to enable broader and deeper responses.
- Computational approaches to refine target identification, receptor identification and optimization.
- Strategies to enhance T cell functionality, persistence, and infiltration into the tumor microenvironment (TME) for durable responses.

Scalability:

- Approaches to streamline and simplify manufacturing processes, increasing access to adoptive cell therapies (ACTs) for more patients.
- Development of innovative methods, such as in vivo manufacturing, to generate cellular immunotherapies more efficiently and lower costs.

Clinical considerations:

- Patient stratification using genetic or molecular markers and advanced computational methods to identify those most likely to benefit.
- Safety frameworks to mitigate risks, from target selection to clinical toxicities, including preclinical model development and clinical toxicity management strategies.

Frequently asked questions

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

     

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

  • Yes, we would love to hear your ideas for a topic. Most of our Research Topics are community-led and suggested by researchers in the field. Our in-house editorial team will contact you to talk about your idea and whether you’d like to edit the topic. If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.

  • A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

    The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

  • As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

     

    You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.
