Transplantation

Alloimmune T cell responses have a crucial role in graft rejection. Here, the authors examine the factors that regulate T cell activation, differentiation and function in secondary lymphoid organs and in the graft, including the different pathways of allorecognition, innate–adaptive immunity crosstalk and the role of survival cytokines.

Lung transplantation is hindered by the scarcity of organs and by mortality following primary graft dysfunction. Here, the authors show that cytokine absorption can be used in donor lungs during ex vivo lung perfusion and post-transplant, and leads to restored lung function and reduced primary graft dysfunction in animal models.
