Author Response: Involvement of ILC1-Like Innate Lymphocytes in Human Autoimmunity, Lessons from Alopecia Areata
February 2023
New to Alopecia Areata? There is a guide in the encyclopedia. Read the guide → Studysummary This study found that innate lymphoid cells-type 1 (ILC1) can induce alopecia areata by disrupting hair follicle immune privilege without the involvement of classical CD8+ T cells.

The study examines the involvement of ILC1-like innate lymphocytes in alopecia areata (AA), identifying a novel population of NKG2D+ ILC1-like cells that secrete IFN-γ, contributing to hair follicle immune privilege loss and hair fiber dystrophy. Through rigorous phenotyping using markers such as CD49a, CD200R, CD127, and CXCR6, the authors differentiate these cells from NK cells, challenging the notion that AA is solely driven by CD8+ T cells. Despite limitations in ex vivo and in vivo models and budget constraints preventing single-cell RNA sequencing, the study provides insights into AA's molecular biology and proposes new therapeutic targets. Further research is suggested to refine the characterization of ILC1-like cells and explore their role in AA.
