Autoimmunity and Periodontitis

Journal of Periodontal Research, EarlyView.
In a microbe‐driven inflammatory environment, peptidyl‐arginine deiminase (PAD) enzymes from neutrophils and Porphyromonas gingivalis citrullinate both microbial and self‐antigens. B cell presentation of citrullinated or self‐mimicking epitopes activates T cells that assist B cells in antibody isotype switching, affinity maturation, epitope spreading ...

Image‐based evaluation of a commercial AI synthetic CT generator for brain and prostate MR‐only radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Synthetic CTs (sCT) were developed to provide electron density information for MR‐only treatment planning. Some AI‐based sCT generators have received FDA‐clearance and better capture tissue heterogeneity through voxel‐wise mappings to improve image guidance and dose calculation.
