However, this was not unexpected since previous reports have shown that GARP identifies the subset of highly suppressive, activated Foxp3+ Treg cells.42, 43 Apart from Treg, the type I transmembrane protein GARP, which binds and activates latent TGF‐β isoforms, is typically expressed also on platelets.42, 43 Both Treg and platelets contribute to the establishment of immune tolerance44 with missense mutations of GARP being associated with atopic dermatitis.45 The gene discussed is TGFB1; the disease is atopic eczema.
