Human cerebral arterial morphogenesis explored by 3D microscopic imaging of cleared embryos: Bridging the gap between embryonic and adult anatomy

Journal of Anatomy, EarlyView.
We provide a description of human embryonic cerebral arterial development based on whole‐mount immunostaining, tissue clearing, three‐dimensional (3D) light‐sheet microscopy imaging, and anatomically informed virtual segmentation of human embryos. Findings are compared with adult radiological anatomy. We provide a detailed account of the development of

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 ...
