Background

Immunotherapy, particularly through the use of recombinant antibodies and T cell receptor (TCR) engineered T-cell therapies, has significantly advanced the targeting of intracellular neoantigens in both benign and malignant diseases. These therapies, including TCR-T cells, TCR chimeric antigen receptor T-cells (TCR-CAR T-cells), and TCR-like CAR T-cells, leverage the specificity of TCRs to recognize and attack tumor cells presenting neoantigens. Additionally, modalities like STAR and T-CARS employ double-chain TCRαβ-based receptors that mimic natural TCR signaling, further enhancing therapeutic efficacy. Despite their potential, challenges such as antigen variability, tumor heterogeneity, and an immunosuppressive tumor microenvironment persist, impacting the efficacy and application of these therapies.

This Research Topic aims to conduct a thorough comparison of the current T cell therapies and recombinant antibody therapies, elucidating their respective advantages and disadvantages in clinical settings. It seeks to address how these therapies can be optimized for better specificity and efficacy, and how emerging technologies like CRISPR/Cas9, immune checkpoint inhibitors and mRNA delivery systems can be integrated to overcome existing limitations.

To gather further insights into these innovative therapies, we welcome articles addressing, but not limited to, the following themes:
o T cells and TCR-T-cell therapy
o Innovations in STAR, T-CARs and TCR-CAR T-cell formats
o TCR-like CAR-T cells
o Developments in recombinant antibodies targeting MHC/neopeptide complexes
o Bispecific antibodies formats like CD3 x TCR-like antibody and CD3 x TCR antibody
o Intrabodies and their role in neutralizing intra-tumoral neoantigens
o CD8+ T cell therapy advancements and challenges (e.g. CD8-fit T cells)
o Harnessing and modulating the tumor microenvironment to boost adoptive T cell therapy


Please note that manuscripts consisting solely of bioinformatics or computational analysis of public genomic or transcriptomic databases which are not accompanied by robust and relevant validation (clinical cohort or biological validation in vitro or in vivo) are out of scope for this Research Topic.

Topic editors

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.

  • As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).

  • 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. This provides you with valuable editorial experience, improving your ability to critically evaluate research articles and enhancing your understanding of the quality standards and requirements for scientific publishing, as well as the opportunity to discover new research in your field, and expand your professional network.

  • Yes, certificates can be issued on request. We are happy to provide a certificate for your contribution to editing a successful Research Topic.
