From chronic pain to depression: Neurogenesis- driven microglial remodeling in the hippocampal dentate gyrus Ming Ding1,2,3,4†, Shitong Xiang1†, Yuqing Zhang1, Lei Wei1,5, Yuanfeng Weng1, Xueting Zhang1, Yiling Ni1, Yuwen Zhang1, Qianfeng Wang1, Ruiqing Hou1, Huaihao Du1, Ka Kei Chio1, Wei Zhang1, He Wang1,4, Tianye Jia1,4,6, Yi Wu2, Jianfeng Feng1,4,7*, Trevor W. Robbins1,8*, Xiao Xiao1,2,3,4* Chronic pain often evolves into depression and anxiety, yet mechanisms linking sensory distress to affective dysfunction remain unclear. Integrating human neuroimaging from the UK Biobank with a rodent model, we uncovered biphasic hippocampal remodeling. Hippocampal volume increased during early pain stages, with paradoxical cognitive improvements, but declined with comorbid depression. …
