Dysregulated activation of the NLRP3 inflammasome, driven by NF-κB and STAT3 signaling, may exacerbate disease pathogenesis, highlighting this axis as a potential therapeutic target. Although traditional Chinese medicine has shown promise in antiviral and anti-inflammatory applications, it remains unclear whether it can inhibit BVDV replication via the NF-κB/STAT3-NLRP3 pathway. The present study aimed to clarify the inhibitory effect of luteolin on bovine viral diarrhea virus (BVDV) replication, and to elucidate its underlying mechanisms from two perspectives: interference with viral internalization and replication processes, as well as regulation of the NF-κB/SVeterinary sciencesLuteolin Inhibits Bovine Viral Diarrhea Virus Replication by Disrupting Viral Internalization and Replication and Interfering with the NF-κB/STAT3-NLRP3 Inflammasome Pathway.PMC128464342521993028/2025No. SCCXTD-2024-13Cai DShen ZMa LTian BMa XLiu QGao JLin YWang YfalseLuteolin Inhibits Bovine Viral Diarrhea Virus Replication by Disrupting Viral Internalization and Replication and Interfering with the NF-κB/STAT3-NLRP3 Inflammasome Pathway.Bovine viral diarrhea virus (BVDV) causes severe mucosal inflammation in cattle, and effective treatment options remain limited.
