A review by Du and colleagues in ACS Biomaterials Science & Engineering surveys the biophysical mechanisms by which endogenous and externally applied direct-current electric fields shape macrophage immune responses. Both types of field modulate electrotaxis, M1/M2 phenotypic polarization, and phagocytic activity via surface charge redistribution, growth factor receptors, and ion channels feeding into PI3K/Akt, MAPK, and NF-ÎșB pathways. The authors argue that distinguishing physiological endogenous fields from therapeutic applied fields provides a theoretical basis for bio-mimetic immunomodulatory strategies.
🔬 This research is covered in EMF Signal's section on therapeutic EMF applications. It investigates controlled use of electromagnetic fields as potential treatment, not environmental exposure.

"Bioelectrical signals, particularly endogenous direct-current electric fields (EFs), constitute a pivotal yet often underappreciated class of physical cues within the cellular microenvironment."

— Du et al. (study authors)

"Accumulating evidence indicates that both endogenous and applied direct current EFs can significantly modulate key macrophage behaviors, including electrotaxis, phenotypic polarization (M1/M2), and phagocytic activity."

— Du et al. (study authors)

"A rigorous dissection of the biophysical and molecular mechanisms governing these responses is essential for elucidating the role of physical signaling in tissue repair, chronic inflammation, and the tumor microenvironment."

— Du et al. (study authors)

"Future efforts should focus on characterizing the in vivo spatiotemporal dynamics of EFs, unraveling cell-type-specific response mechanisms, and assessing the translational feasibility of these fundamental insights."

— Du et al. (study authors)
