Why Your Skin Never Forgets Inflammation, Even Years Later
Graded Preliminary — mouse study of epidermal stem cells after psoriasis-like skin flares, with no human data yet and no animal count given.
Animal study. Findings may not carry over to people, which is why the grade is capped at Preliminary.
This study suggests past inflammatory episodes may permanently alter tissue responses to future stressors.
In mice, skin stem cells can hold lifelong "memories" of past inflammation like psoriasis flares. These memories are stored as epigenetic changes. Specific DNA sequences rich in CpG patterns keep the memory accessible through cell divisions. This means once skin has been inflamed, its stem cells stay primed to react faster and stronger to future triggers.
