Abstract:
Breast cancer (BC) remains one of the most prevalent and deadly malignancies among women globally. A deeper understanding of the molecular mechanisms driving BC progression and metastasis is essential for the development of effective therapeutic strategies. While traditional chemokine receptors are well known for their roles in immune cell migration and positioning, atypical chemokine receptors (ACKRs) have recently gained attention as key modulators in cancer-related processes. Unlike conventional receptors, ACKRs-comprising ACKR1, ACKR2, ACKR3, and ACKR4-primarily function by scavenging chemokines, regulating their availability, and modulating receptor signaling in a ligand-independent manner. This review aims to elucidate the roles of ACKRs in BC, focusing on their influence on the tumor microenvironment (TME), cancer cell proliferation, survival, metastasis, and angiogenesis. Additionally, we will explore the potential of ACKRs as diagnostic and prognostic markers and assess their viability as therapeutic targets. By synthesizing recent research findings and highlighting future research directions, this review seeks to provide a comprehensive understanding of the significance of ACKRs in BC and underscore the need for continued investigation into their therapeutic potential.
