A substantial proportion of GBS cases are precipitated by infectious agents, most notably\n                    <jats:italic>Campylobacter jejuni<\/jats:italic>\n                    and\n                    <jats:italic>Haemophilus influenzae<\/jats:italic>\n                    , which initiate pathogenic autoimmunity via molecular mimicry. This narrative review aimed to synthesize current evidence on the microbial triggers of GBS and elucidate the immune mechanisms linking infection to neuropathic damage. We discuss the evolving landscape of GBS pathogenesis, emphasizing the roles of ganglioside\u2010like lipooligosaccharide (LOS), host genetic predisposition, and dysregulated immune responses. The clinical heterogeneity of GBS subtypes, including axonal and demyelinating variants, was analyzed in relation to serotype\u2010specific antibody profiles that inform the diagnosis and prognosis. Current therapeutic interventions, including intravenous immunoglobulin and plasma exchange, are critically assessed alongside experimental strategies, such as monoclonal antibody therapies, microbiome modulation, and LOS\u2010targeted vaccines. This review highlights microbial surveillance and precision immunotherapy in the management of GBS. Collectively, this study underscores the central role of microbiological insights in redefining the prevention, diagnosis, and treatment of this complex neuroimmune disorder.\n                  <\/jats:p>","DOI":"10.1002\/mbo3.70177","type":"journal-article","created":{"date-parts":[[2025,11,28]],"date-time":"2025-11-28T04:45:06Z","timestamp":1764305106000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Infectious Triggers and Immune Dynamics in Guillain\u2013Barr\u00e9 Syndrome: Revisiting\n                    <i>Campylobacter jejuni<\/i>\n                    and the Silent Role of\n                    <i>Haemophilus influenzae<\/i>"],"prefix":"10.1002","volume":"14","author":[{"given":"Aswathi","family":"Ramesh","sequence":"first","affiliation":[{"name":"Centre for Advanced Biotherapeutics and Regenerative Medicine, Faculty of Research, Chettinad Hospital and Research Institute, Chettinad Academy of Research and Education Kelambakkam India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5890-5273","authenticated-orcid":false,"given":"Rajasekaran","family":"Subbarayan","sequence":"additional","affiliation":[{"name":"Centre for Advanced Biotherapeutics and Regenerative Medicine, Faculty of Research, Chettinad Hospital and Research Institute, Chettinad Academy of Research and Education Kelambakkam India"},{"name":"Centre for Herbal Pharmacology and Environmental Sustainability, Chettinad Hospital and Research Institute, Chettinad Academy of Research and Education Kelambakkam India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dhasarathdev","family":"Srinivasan","sequence":"additional","affiliation":[{"name":"Centre for Advanced Biotherapeutics and Regenerative Medicine, Faculty of Research, Chettinad Hospital and Research Institute, Chettinad Academy of Research and Education Kelambakkam India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ranjith","family":"Balakrishnan","sequence":"additional","affiliation":[{"name":"Centre for Advanced Biotherapeutics and Regenerative Medicine, Faculty of Research, Chettinad Hospital and Research Institute, Chettinad Academy of Research and Education Kelambakkam India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6804-6070","authenticated-orcid":false,"given":"Rupendra","family":"Shrestha","sequence":"additional","affiliation":[{"name":"Department of Natural and Applied Sciences Nexus Institute of Research and Innovation (NIRI) Lalitpur Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7707-1032","authenticated-orcid":false,"given":"Ankush","family":"Chauhan","sequence":"additional","affiliation":[{"name":"Centre for Herbal Pharmacology and Environmental Sustainability, Chettinad Hospital and Research Institute, Chettinad Academy of Research and Education Kelambakkam India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,11,27]]},"reference":[{"key":"e_1_2_17_2_1","volume-title":"Elucidating the Potential Role of Aryl Hydrocarbon Receptor in the Pathogenesis of Campylobacter jejuni","author":"Ahmed H.","year":"2022"},{"key":"e_1_2_17_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/jns.12266"},{"key":"e_1_2_17_4_1","doi-asserted-by":"publisher","DOI":"10.3390\/biomedinformatics4020073"},{"key":"e_1_2_17_5_1","unstructured":"\u0391\u03c1\u03bc\u03c0\u03bf\u03c5\u03bd\u03b9\u03ce\u03c4\u03b7 \u0399 Usage of Machine Learning and Computational Chemistry Methodologies to Predict the Activity of Potential Antiviral Compounds Against the Zika Virus Protease.2024."},{"key":"e_1_2_17_6_1","volume-title":"Haemophilus influenzae and Moraxella catarrhalis Intra\u2010and Interspecies Quorum Signaling","author":"Armbruster C.
