064 Functional interrogation of lymphocyte subsets in alopecia areata using single-cell RNA sequencing

Abstract

Alopecia areata (AA) is one of the most prevalent autoimmune diseases, yet the development of innovative therapeutic strategies has been hampered by an incomplete understanding of disease pathogenesis, such as the complex immunological mechanisms that underlie AA pathogenesis. Here, we performed single-cell RNA sequencing (scRNAseq) of skin-infiltrating immune cells from the well-established graft-induced C3H/HeJ mouse model of AA, together with antibody-based depletion experiments to systematically interrogate the role of specific immune cell types in disease pathophysiology in vivo.
