The Hidden Architecture
of Disease

Microcirculation, biological barriers, immune memory, tissue remodeling and the failure of repair.

31 independent papers · Free full-text HTML · Individual PDF / Markdown / TXT · Selected peer-reviewed readings

This collection asks what may sustain tissue-level dysfunction after the original injury has diminished. It combines established mechanisms and clearly identified hypotheses; it is not a report of clinical trials or a treatment guide.
