About this Research Topic

Background

Pancreatic cancer remains one of the deadliest threats to human life, and there is an urgent need for effective treatment strategies. The tumor microenvironment (TME) comprising abnormal tumor blood vessels, extracellular matrix components, endothelial cells, pericytes, tumor-associated fibroblasts, smooth muscle cells, and immune cells, plays a crucial role in the occurrence, growth, and metastasis of tumors. The immunosuppressive nature of the TME significantly contributes to the failure of various anti-tumor treatments, including immunotherapy. Clinical evidence for therapies targeting the tumor immune microenvironment in pancreatic cancer is limited compared to treatments involving anti-PD-1/PD-L1 or CTLA-4 antibodies. Addressing the complexity and heterogeneity of the tumor immune microenvironment through research at the single-cell and molecular levels can provide practical and precise solutions for diverse patient populations and cancer types, which is promising for enhancing the therapeutic efficacy targeting the tumor immune microenvironments. In recent years, many studies have increasingly focused on improving therapeutic efficacy by targeting and reshaping TME.

This topic aims to elaborate on the latest strategies and studies for targeting and reshaping the tumor microenvironment (TME) of pancreatic cancer, providing innovative approaches for pancreatic cancer treatment. Key strategies include improving tumor hypoxia, targeting tumor blood vessels, targeting tumor-associated fibroblasts, extracellular matrix components, tumor-associated macrophages, dendritic cells, and so on. These approaches aim to enhance the infiltration of drugs and endogenous anti-tumor immune cells by weakening the matrix barrier or improving the immunosuppressive microenvironment, thereby enhancing the effectiveness of anti-tumor therapy. Existing issues and exploration of future developments in this field are both highly welcome in this topic.

Specifically, researchers are welcome to address, but not limited to, the following sub-topics.
● Small molecule drugs targeting oncogenic pathways in tumor cells and tumor microenvironment of pancreatic cancer
● The latest technology for developing small molecules that directly stimulate anti-tumor immune responses in pancreatic cancer
● Establishment and treatment strategy of targeted drugs for pancreatic cancer based on cross-presentation
● Drug development targeting KRAS to drive immune remodeling of tumor microenvironment of pancreatic cancer
● Drug delivery system targeting the tumor stromal microenvironment of pancreatic cancer
● Targeting the tumor microenvironment to regulate tumor cell metabolism and enhance anti-pancreatic cancer immunotherapy strategies
● New immunotherapy targets for reshaping the tumor microenvironment of pancreatic cancer
● Immune combination therapy reprogramming tumor immune microenvironment for pancreatic cancer treatment
● Application of artificial intelligence in biomarkers and target drug development of pancreatic cancer

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 they fall 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?

  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.
