Special Issue Information

Dear Colleagues,

Head and neck squamous cell carcinoma (HNSCC) remains a major clinical challenge due to its high heterogeneity, frequent late-stage diagnosis, and resistance to conventional therapies. Central to its pathogenesis is the tumor microenvironment (TME), which is a complex and dynamic network composed of cancer cells, stromal cells, immune infiltrates, extracellular matrix components, and signaling molecules. This environment plays a crucial role in modulating tumor growth, invasion, immune escape, and therapy resistance.

Exosomes, which are small extracellular vesicles released by both tumor and stromal cells, have gained increasing attention as key players in cell-to-cell communication within the TME. They carry bioactive molecules such as proteins, RNAs, and microRNAs that can reshape the immune response, promote angiogenesis, support metastatic spread, and mediate drug resistance. Exosomes also offer potential as non-invasive biomarkers and therapeutic targets.

Understanding the cellular and molecular interactions within the TME, including the roles of cancer-associated fibroblasts (CAFs), immune checkpoints, and tumor-infiltrating lymphocytes (TILs), is essential for advancing precision medicine in HNSCC.

The current Special Issue invites contributions focused on the molecular and cellular components of the TME in HNSCC, aiming to uncover novel insights for improved prognosis and therapeutic innovation.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Biomedicines is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
