They share mechanisms such as overexpression of pro-inflammatory cytokines. Anti-TNF-a agents like adalimumab are effective, but up to 40% of patients do not respond. This thesis developed a PET-based methodology using [89Zr]Zr-DFOadalimumab to analyze biodistribution and pharmacokinetics in murine models of inflammatory bowel disease, uveitis, and rheumatoid arthritis, administered intravenously, subcutaneously, and intravitreally. This work opens new possibilities for both diagnosis and individualized therapeutic monitoring in inflammatory diseases (theragnosis).engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/PETantiTNFadalimumab320910 Radiofármacos241202 Anticuerposdoctoral thesisopen access
