DEFB133 is a member of the beta‐defensin family, typically involved in innate immunity and cellular stress responses. The first study (which examines the role of the epigenetic regulator ZBTB4 in maintaining genomic stability through proper mitotic checkpoint function) suggests that pathways ensuring chromosomal integrity might intersect with cellular processes—such as stress response and signaling modulation—that are also influenced by defensin peptides."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nIn the second study, BMSC‐secreted exosomes were shown to modulate astrocyte activation following spinal cord injury, highlighting mechanisms of neuroprotection and inflammation control.
