Although, anti-inflammatory effects of CAP are studied, there are no reports investigating its effect on T cell hyperactivation associated pathologies. This study examines CAP&#8217;s impact on antigen driven and homeostatic T cell proliferation and its potential to prevent acute graft-versus-host disease (aGvHD). CAP treatment significantly attenuated GvHD-associated mortality and morbidity in mice. CAP inhibited stimulation-induced T cell activation, surface marker expression, cytokine secretion, and proliferation without inducing cell death, indicating non-cytotoxic immunomodulation. CAP modulated cellular redox and pre-treatment with N-acetylcysteine (NAC) or PEG-catalase (PEG-CAT) abrogated CAP-mediated suppression of mitogen-induced T cell responses. Moreover, CAP-mediated inhibition of stimulation-induced T-cell responses was associated with suppression of immune-regulatory, redox-sensitive transcription factors, NF-\u03baB and Nrf2. These findings underscore immunotherapeutic potential of CAP in treatment of disorders linked to T cell hyperactivation.<\/p>\n<p>PMID:<a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/42394517\/?utm_source=SimplePie&amp;utm_medium=rss&amp;utm_content=8405628&amp;ff=20260703071154&amp;v=2.20.0\">42394517<\/a> | DOI:<a href=\"https:\/\/doi.org\/10.1093\/jleuko\/qiag066\">10.1093\/jleuko\/qiag066<\/a><\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>J Leukoc Biol. 2026 Jul 3:qiag066. doi: 10.1093\/jleuko\/qiag066.
