  2026-08-08

  A translational perspective on how tumor-directed PAD4 inhibition, m-PBA-mediated uptake, and NET pathway control may improve mechanistic cancer research while guiding rigorous preclinical study design.

• IBDV VP3 Disrupts IRF7 Antiviral Signaling

  2026-08-07

  Wang et al. identify an immune-evasion mechanism in which infectious bursal disease virus VP3 suppresses IRF7-dependent type I interferon signaling and promotes proteasome-associated IRF7 loss. The study combines viral strain comparison, IRF7 gain- and loss-of-function experiments, inhibitor testing, and VP3 interaction analyses to connect host-factor degradation with enhanced viral replication.

• Kir4.1-ROS-p38 MAPK Pathway Drives Orofacial Neuropathic Pai

  2026-08-07

  This study uncovers how downregulation of Kir4.1 in trigeminal ganglion satellite glial cells leads to orofacial neuropathic pain through a cascade involving increased ROS, activation of p38 MAPK, and upregulation of pannexin 3. The mechanistic insights clarify pain sensitization pathways and suggest new molecular targets for intervention.
