Ossification of the posterior longitudinal ligament (OPLL) is a progressive spinal disease characterized by ectopic bone formation in the spine, leading to severe neurological symptoms due to spinal cord compression. This condition is more prevalent in Asian countries and has been associated with various genetic and hormonal factors. Recent insights reveal the potential role of interferon (IFN) signaling in the pathogenesis of OPLL, particularly the type I IFN pathway, which is known to play a role in innate immune responses and bone formation. A single-cell transcriptome profiling study has identified the activation of type I IFN signaling in ossified posterior longitudinal ligament, suggesting a therapeutic target for OPLL.
