Abstract
Although alopecia areata (AA) is recognized as a hair loss disorder stemming from the dysregulation of cutaneous immune homeostasis, its precise pathogenesis still remains elusive. The collapse of hair follicle (HF) immune privilege (IP), leading to immune cell-mediated attack on the hair follicle, is currently the widely accepted fundamental mechanism of AA. Among the immune cells studied in this context, CD8+ T cells and regulatory T (Treg) cells are relatively well-researched, but the direct involvement of macrophages in the disease process has been less frequently demonstrated. In this review, we summarize various previous studies on macrophages and hypothesize the immune mechanisms by which macrophages contribute to the pathogenesis of AA. This exploration provides new insights for future research and potential clinical treatments.
期刊介绍：
Clinical Reviews in Allergy & Immunology is a scholarly journal that focuses on the advancement of clinical management in allergic and immunologic diseases. The journal publishes both scholarly reviews and experimental papers that address the current state of managing these diseases, placing new data into perspective. Each issue of the journal is dedicated to a specific theme of critical importance to allergists and immunologists, aiming to provide a comprehensive understanding of the subject matter for a wide readership.
The journal is particularly helpful in explaining how novel data impacts clinical management, along with advancements such as standardized protocols for allergy skin testing and challenge procedures, as well as improved understanding of cell biology. Ultimately, the journal aims to contribute to the improvement of care and management for patients with immune-mediated diseases.
