Special Issue Information

Dear Colleagues,

This Special Issue, titled "Molecular Mechanisms of Bone Metastasis in Cancer", aims to explore the intricate biological and immunological processes that govern cancer cell dissemination and colonization in the bone microenvironment.

Bone metastasis is a devastating and frequent complication in advanced cancers, particularly in breast, prostate, and lung malignancies. It arises from complex bidirectional interactions between tumor cells and components of the bone niche, including osteoclasts, osteoblasts, immune cells, stromal cells, and the extracellular matrix. These interactions result in dynamic remodeling of the bone, immune evasion, and the establishment of a permissive pre-metastatic niche.

We invite original research articles and reviews that provide mechanistic insights into the following:

  • Tumor cell homing, dormancy, and colonization in bone;
  • RANKL/OPG, TGF-β, and Wnt signaling pathways in tumor–bone crosstalk;
  • Cytokine and chemokine signaling networks;
  • The role of myeloid-derived suppressor cells (MDSCs) and immune checkpoints in metastasis;
  • Epigenetic and metabolic reprogramming of the bone niche;
  • The contribution of extracellular vesicles and exosomes to bone tropism;
  • Preclinical models investigating tumor–bone–immune cell interactions.

By highlighting key molecular pathways and cellular dynamics, this Special Issue seeks to advance our understanding of the immune biology underlying bone metastasis and to support the development of innovative therapeutic strategies.

We look forward to your contributions to this important topic.

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 250 words) can be sent to the Editorial Office for assessment.

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. Biology is an international peer-reviewed open access semimonthly 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 2700 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.

Abstract
Bone metastases represent a major cause of morbidity in advanced cancers, yet the neural regulation of metastatic growth within bone remains largely unexplored. The skeletal system is richly innervated by sensory and sympathetic nerve fibers that influence bone remodeling, hematopoiesis, and immune surveillance. [...] Read more.
Bone metastases represent a major cause of morbidity in advanced cancers, yet the neural regulation of metastatic growth within bone remains largely unexplored. The skeletal system is richly innervated by sensory and sympathetic nerve fibers that influence bone remodeling, hematopoiesis, and immune surveillance. Emerging evidence suggests that disseminated tumor cells exploit these neural circuits to create a growth-permissive microenvironment. Tumor-secreted neurotrophic factors can induce nerve sprouting, while sympathetic activation via β-adrenergic receptors promotes osteoclastogenesis, immunosuppression, and tumor proliferation. Neuropeptides such as substance P and calcitonin gene-related peptide exert dual effects on bone cells and infiltrating immune populations, further shaping the metastatic niche. The interplay between neural signals, osteolytic activity, and immune modulation positions the neuro–bone axis as a critical but underappreciated driver of metastatic progression. In this review, we synthesize current evidence on the anatomy and function of bone innervation, tumor-induced neural remodeling, and neuro–immune–osteoclast interactions. We highlight preclinical and clinical data supporting neuromodulatory strategies, including β-blockers, neurotrophin inhibitors, and targeted nerve ablation, as potential adjuncts to standard bone metastasis therapies. Finally, we identify key knowledge gaps, including the need for spatial and functional mapping of nerve–tumor interfaces and for integrating neuroimaging into bone metastasis detection. By framing the neuro–bone axis as a therapeutic target, we aim to catalyze interdisciplinary research that bridges oncology, neuroscience, and bone biology, with the goal of disrupting neural support for metastatic growth Full article
