Antibody-mediated rejection (AMR) is an important cause of graft loss and continues to present a formidable obstacle to successful transplantation. Unresolved problems continue to be the absence of effective strategies to ablate the donor-specific antibody (DSA) response as well as to attenuate the antibody-mediated graft tissue injury. While the properties of DSA that cause greater graft tissue injury and the characteristic microvascular pathology of the graft injury are well documented, the mechanisms underlying the injury mediated by the antibodies remains unclear. Recent transcriptome interrogation of kidney and heart biopsies procured during ongoing AMR has indicated the expression of genes associated with natural killer (NK) cell activation that is absent during T cell–mediated rejection. The expression of NK cell transcripts during AMR correlates with the presence of CD56+ cells in the microcirculation inflammation observed during AMR. Several mouse models have recently demonstrated the role of NK cells in antibody-mediated chronic vasculopathy in heart allografts and the requirement for NK cell activation during acute AMR of kidney allografts. In the latter model, NK cell activation within kidney allografts is regulated by the activation of myeloid cells producing myeloperoxidase. Overall, the studies to date indicate that AMR constitutes a complex series of DSA-induced interactions with components of the innate immune response. The innate immune participants and their expressed effector functions resulting in the rejection are beginning to be identified. The identification of these components should uncover novel targets that can be used to attenuate acute graft tissue injury in the presence of DSA.

Cannabis, or marijuana, comprises many compounds with varying effects. It has become a treatment option for chronic diseases and debilitating symptoms, and evidence suggests that it has immunomodulatory and antiinflammatory properties. Transplant centers are more frequently facing issues about cannabis, as indications and legalization expand. As of February 2020, 33 states and the District of Columbia have legalized medical cannabis, and 14 have legalized recreational cannabis. Moreover, 8 states have passed legislation prohibiting the denial of transplant listing solely based on cannabis use. Studies demonstrate the potential for significant pharmacokinetic and pharmacodynamic interactions between cannabis and immunosuppression. Additionally, safety concerns include increased risk of myocardial infarction, ischemic stroke, tachyarrhythmias, malignancy, neurocognitive deficits, psychosis, other neuropsychiatric disorders, cannabis use disorder, respiratory symptoms, and infection. A recent retrospective database study found a negative association between documented cannabis use disorder and graft survival, but little additional evidence exists evaluating this relationship. In the absence of robust clinical data, transplant centers need a clear, reasoned, and systematic approach to cannabis. The results of our national survey, unfortunately, found little consensus among institutions. As both recreational and medicinal cannabis become more ubiquitous nationwide, transplant centers will need to develop comprehensive policies to address its use.

Advances in genetic engineering, particularly CRISPR/Cas9, have resulted in the development of a triple glycan-knockout (TKO) pig. There is minimal human antipig antibody binding to TKO pig cells. The TKO background has decreased antibody binding to a sufficiently low level that any additional xenoantigens expressed on the cells can now be more easily detected. One of these xenoantigens is the swine major histocompatibility complex, termed swine leukocyte antigens (SLA). SLA are the homolog to HLAs, a protein complex expressed on human tissue capable of stimulating the development of new antibodies in allotransplantation. These antibodies can result in graft failure through hyperacute, acute, or chronic rejection. Our knowledge of SLA, particularly in the last 5 years, has grown considerably. The presence, cause, and methods to detect anti-SLA antibodies will need to be carefully considered for the first clinical trial of xenotransplantation. The focus of this review is to summarize the role of SLA in xenotransplantation and consider whether it will prove to be a major barrier. Techniques are now available to mutate target SLA amino acids to ensure that cross-reactive anti-HLA antibodies no longer bind to SLA on the cells of the organ-source pigs. While deletion of SLA expression is possible, it would render the pig at risk for infectious complications. The ideal organ-source pig for HLA highly sensitized recipients may therefore be 1 with site-specific mutations to eliminate cross-reactive binding.

Ischemia-reperfusion injury (IRI) is the major cause of primary graft dysfunction in organ transplantation. The mitogen-activated protein kinase/extracellular signal-regulated kinase (ERK) signaling pathway plays a crucial role in cell physiological and pathological processes including IRI. This study aims to investigate whether inhibition of ERK signaling with U0126 can prevent prolonged cold IRI in heart transplantation.

Natural preformed anti-pig IgM/IgG antibodies in primates play an important role in xenograft rejection. As it is not clear how IgE and IgA engage in the immune system in xenotransplantation, we investigated natural preformed and elicited anti-pig IgE/IgA in naive primates and after xenotransplantation in nonhuman primates.

Extended-spectrum ?-lactamase–producing Enterobacteriaceae (ESBL-E) carriage is frequent among liver transplant (LT) recipients, thereby fostering a large empirical carbapenem prescription. However, ESBL-E infections occur in only 10%–25% of critically ill patients with rectal colonization. Our aim was to identify risk factors for post-LT ESBL-E infection in colonized patients. The effect of perioperative antimicrobial prophylaxis (AP) was also analyzed in patients with prophylaxis lasting <48 hours and without proven intraoperative infection.

Donor-recipient oversizing based on predicted total lung capacity (pTLC) is associated with a reduced risk of primary graft dysfunction (PGD) following lung transplant but the effect varies with the recipient’s diagnosis. Chest x-ray (CXR) measurements to estimate actual total lung capacity (TLC) could account for disease-related lung volume changes, but their role in size matching is unknown.

Procuring a good quality transbronchial-biopsy sample is essential for diagnosing acute cellular rejection after lung transplantation (LT). Insufficient transbronchial-biopsy samples are graded “AX.” We hypothesized that AX samples may be associated with a higher risk for chronic lung allograft dysfunction (CLAD) or death/retransplant, through a potential anatomic or physiologic underlying pulmonary process or because of undiagnosed acute cellular rejection episodes.
