Material and methods: This narrative review was based on a structured search of the PubMed, Scopus, and Web of Science databases, including studies published between 2010 and 2025. Keywords related to post-traumatic stress disorder, inflammation, cytokines, stress response, and neuroendocrine regulation were used. Clinical and experimental studies addressing stress\u2013immune interactions were included. Results: Post-traumatic stress disorder is increasingly conceptualized as a systemic condition involving persistent dysregulation of neuroendocrine and immune pathways. Disturbances of the hypothalamic\u2013pituitary\u2013adrenal axis, including altered glucocorticoid receptor sensitivity and impaired negative feedback regulation, coexist with increased sympathetic nervous system activity. These abnormalities promote activation of pro-inflammatory transcription factors such as nuclear factor kappa B and increased production of cytokines, including interleukin-1 beta, interleukin-6, tumour necrosis factor alpha, and interleukin-18. Additional mechanisms include activation of the NLR family pyrin domain containing 3 inflammasome, oxidative stress, mitochondrial dysfunction, and microglial activation, which contribute to neuroinflammation and impaired synaptic plasticity. These processes are associated with both psychiatric symptoms and increased risk of cardiovascular and metabolic comorbidities. Conclusions: Post-traumatic stress disorder may be understood as a disorder of maladaptive stress\u2013immune interaction. Targeting inflammatory pathways and stress-response mechanisms may improve diagnostic approaches and support the development of personalized therapeutic strategies.<\/jats:p>","DOI":"10.36740\/wlek\/222497","type":"journal-article","created":{"date-parts":[[2026,9,16]],"date-time":"2026-09-16T09:39:33Z","timestamp":1789551573000},"page":"1667-1675","source":"Crossref","is-referenced-by-count":0,"title":["Dysregulation of Immune and Stress Responses in Post-Traumatic Stress Disorder: Increased Inflammation and Altered Stress Signalling Pathways"],"prefix":"10.36740","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5425-6210","authenticated-orcid":false,"given":"EWa Alicja","family":"Og\u0142odek","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"22436","published-online":{"date-parts":[[2026,7,30]]},"container-title":["Wiadomo\u015bci Lekarskie"],"original-title":[],"link":[{"URL":"https:\/\/www.wiadomoscilekarskie.pl\/pdf-222497-145236","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.wiadomoscilekarskie.pl\/pdf-222497-145236","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,16]],"date-time":"2026-09-16T09:39:42Z","timestamp":1789551582000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.wiadomoscilekarskie.pl\/Dysregulation-of-Immune-and-Stress-Responses-in-Post-Traumatic-Stress-Disorder-Increased,222497,0,2.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7,30]]},"references-count":0,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2026]]}},"alternative-id":["222497"],"URL":"https:\/\/doi.org\/10.36740\/wlek\/222497","relation":{},"ISSN":["0043-5147","2719-342X"],"issn-type":[{"value":"0043-5147","type":"print"},{"value":"2719-342X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,7,30]]}}}
