TLDR Blocking CD44 can reduce leukocyte migration in autoimmune skin diseases.
The study investigated the role of CD44 in leukocyte migration in autoimmune diseases, specifically alopecia areata (AA) and chronic eczema. Researchers explored whether blocking CD44 could inhibit the migration of leukocytes, particularly AA effector cells, using CD44 isoform-specific antibodies. In vitro, anti-panCD44 and anti-CD44v10 antibodies inhibited leukocyte migration in both control and AA mice. In vivo, these antibodies interfered with T cell and monocyte extravasation into the skin, with anti-panCD44 also preventing T cell homing into lymph nodes. The study suggested that targeting AA T cells with a panCD44-CD49d-bispecific antibody could support allergen treatment in AA by selectively inhibiting T cell migration.
