Abstract
Antibody-mediated rejection (AMR) is a recognized cause of allograft dysfunction in lung transplant recipients. Unlike AMR in other solid-organ transplant recipients, there are no standardized diagnostic criteria or an agreed-upon definition. Hence, a working group was created by the International Society for Heart and Lung Transplantation with the aim of determining criteria for pulmonary AMR and establishing a definition. Diagnostic criteria and a working consensus definition were established. Key diagnostic criteria include the presence of antibodies directed toward donor human leukocyte antigens and characteristic lung histology with or without evidence of complement 4d within the graft. Exclusion of other causes of allograft dysfunction increases confidence in the diagnosis but is not essential. Pulmonary AMR may be clinical (allograft dysfunction which can be asymptomatic) or sub-clinical (normal allograft function). This consensus definition will have clinical, therapeutic and research implications.

TL;DR: The clinical and histological manifestations of AMR are described, and the immunopathological mechanisms contributing to antibody-mediated allograft injury as well as current and emerging therapies are discussed.

Non-HLA agonistic anti-angiotensin II type 1 receptor antibodies induce a distinctive phenotype of antibody-mediated rejection in kidney transplant recipients

TL;DR: Those with AT1R antibody-associated rejection had a higher prevalence of hypertension, more vascular rejection with arterial inflammation, higher levels of endothelial-associated transcripts, and lack of complement deposition in allograft capillaries, which could lead to the development of new treatment strategies to improve allografted survival.

Revision of the 1990 Working Formulation for the Standardization of Nomenclature in the Diagnosis of Heart Rejection

TL;DR: This article summarizes the revised consensus classification of lung allograft rejection and recommends the evaluation of antibody-mediated rejection, recognizing that this is a controversial entity in the lung, less well developed and understood than in other solid-organ grafts, and with no consensus reached on diagnostic features.

Revision of the 1990 working formulation for the classification of pulmonary allograft rejection : Lung Rejection Study Group

TL;DR: This article summarizes the updated classification for pulmonary allograft rejection, which is based on perivascular and interstitial mononuclear infiltrates and divided into bronchiolitis obliterans--active or inactive--and vascular atherosclerosis--accelerated arterial or venous sclerosis.

Evolution and Clinical Pathologic Correlations of De Novo Donor‐Specific HLA Antibody Post Kidney Transplant

TL;DR: Pathology consistent with antibody‐mediated injury can occur and progress in patients with dnDSA in the absence of graft dysfunction and furthermore, nonadherence and cellular rejection contribute to dNDSA development and progression to graft loss.
