TLDR Alopecia areata involves complex immune and genetic factors, with potential treatment targets identified, but more research is needed.

The first day of the Alopecia Areata Research Summit in 2013 reviewed advancements in understanding the genetic and immunologic factors of alopecia areata (AA). It was found that both innate and acquired immunity played roles in AA, with genetic studies revealing complex immunologic networks. Key treatment targets identified included NKG2D ligands, IL-15, CTLA-4, and JAK signaling pathways. The modulation of immune privilege was also considered as a potential management strategy. However, the specificity of the immune response in AA, particularly the role of antigen-specific T cells or antibodies, remained unclear. The summit highlighted the need for a strong clinical research platform to test new treatments and further explore these findings.
