Enkephalin-producing regulatory T cells in the skin restrain local inflammation through control of nociception
Overview
Paper Summary
This mouse study found a subset of regulatory T cells in the skin produce enkephalins, natural painkillers, which help control inflammation by dampening pain signals from sensory neurons. Specifically, these enkephalin-producing T cells reduced IL-23 production and other inflammatory responses in a mouse model of psoriasis.
Explain Like I'm Five
Special immune cells in the skin of mice can make natural painkillers. These painkillers calm down other nearby cells that sense pain, and this helps prevent too much inflammation.

Rating Explanation
This is a well-conducted study with a clear hypothesis, appropriate methodology, and compelling results. Although limited to a mouse model and a specific inflammatory context, the findings provide novel insights into the complex interplay between the immune and nervous systems in regulating skin inflammation. The mechanistic insights regarding enkephalin production by Treg cells and their impact on sensory neurons are valuable contributions to the field.
