Although NMO-IgG can induce pathological changes in the central nervous system (CNS), the immunological changes in the CNS and peripheral tissue remain largely unknown. We investigated whether NMO-IgG binds to tissue expressing AQP4 and induces immunological changes in the peripheral tissue and CNS. Methods: C57BL\/6 female mice were assigned into an NMOSD or control group. Pathological and immunological changes in peripheral tissue and CNS were measured by immunostaining and flow cytometry, respectively. Motor impairment was measured by open-field test. Results: We found that NMO-IgG did bind to astrocyte- and AQP4-expressing peripheral tissue, but induced glial fibrillary acidic protein and AQP4 loss only in the CNS. NMO-IgG induced the activation of microglia and modulated microglia polarization toward the classical (M1) phenotype, but did not affect innate or adaptive immune cells in the peripheral immune system, such as macrophages, neutrophils, Th17\/Th1, or IL-10-producing B cells. In addition, NMOSD mice showed significantly less total distance traveled and higher immobility time in the open field. Conclusions: We found that injection of human NMO-IgG led to astrocytopathic lesions with microglial activation in the CNS. However, there were no significant pathological or immunological changes in the peripheral tissues.<\/jats:p>","DOI":"10.31083\/j.jin2306119","type":"journal-article","created":{"date-parts":[[2024,6,21]],"date-time":"2024-06-21T09:22:30Z","timestamp":1718961750000},"source":"Crossref","is-referenced-by-count":1,"title":["Human NMO-IgG Induced Different Pathological and Immunological Changes in the CNS and Peripheral Tissues of Mice"],"prefix":"10.31083","volume":"23","author":[{"given":"Weiwei","family":"Xiang","sequence":"first","affiliation":[{"name":"Department of Neurology, Renji Hospital, Shanghai Jiao Tong University School of Medicine, 200127 Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuwei","family":"Bai","sequence":"first","affiliation":[{"name":"Department of Neurology, Renji Hospital, Shanghai Jiao Tong University School of Medicine, 200127 Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kan","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Neurology, Renji Hospital, Shanghai Jiao Tong University School of Medicine, 200127 Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Peng","sequence":"first","affiliation":[{"name":"Department of Neurology, Renji Hospital, Shanghai Jiao Tong University School of Medicine, 200127 Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ze","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Neurology, Renji Hospital, Shanghai Jiao Tong University School of Medicine, 200127 Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lu","family":"Han","sequence":"first","affiliation":[{"name":"Department of Neurology, Renji Hospital, Shanghai Jiao Tong University School of Medicine, 200127 Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chong","family":"Xie","sequence":"first","affiliation":[{"name":"Department of Neurology, Renji Hospital, Shanghai Jiao Tong University School of Medicine, 200127 Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yangtai","family":"Guan","sequence":"first","affiliation":[{"name":"Department of Neurology, Renji Hospital, Shanghai Jiao Tong University School of Medicine, 200127 Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"16242","published-online":{"date-parts":[[2024,6,20]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","unstructured":"Pittock SJ, Lucchinetti CF.
