Studysummary This review explores the cellular dynamics of graft rejection in vascularized composite allotransplantation and discusses how understanding these processes might lead to innovative treatments for managing rejection. Our plain-language summary of this paper — not a Tressless recommendation.

Vascularized composite allotransplantation (VCA) is a transformative approach in reconstructive surgery for severe injuries, involving the transplantation of multiple tissue types. A significant challenge in VCA is the strong rejection response, particularly due to the antigenicity of components like skin, necessitating lifelong immunosuppression. This review explores the cellular mechanisms involved in graft rejection, highlighting the roles of various immune cells and donor-derived tissues. Recent advancements in understanding these cellular interactions may lead to new therapies targeting specific processes, potentially improving the clinical management of VCA patients.
