Solid-organ transplantation (for example, kidney or liver) and haematopoietic-stem-cell transplantation have revolutionized treatment of end-stage organ failure and haematological malignancies. However, long-term outcomes are often undermined by complications such as allograft rejection, graft-versus-host disease in haematopoietic-stem-cell recipients, opportunistic infections, adverse effects of drugs and decreased quality of life. Emerging evidence now highlights the gut microbiome and its metabolites (such as short-chain fatty acids) as a potentially modifiable factor influencing transplantation outcomes. Transplantation recipients frequently exhibit gut dysbiosis, which has been linked to graft function, risk of infection (for example, vulnerability to multidrug-resistant bacteria), immune-mediated complications and patient survival. Furthermore, pharmacomicrobiomics studies indicate that microorganisms can metabolize immunosuppressive drugs into less active forms (such as the conversion of the immunosuppressive drug tacrolimus into less active or toxic forms through keto-reduction, glucuronidation or deconjugation) or can activate prodrugs (such as the conversion of mycophenolate mofetil into mycophenolic acid), thereby modulating drug efficacy and safety. Here, we discuss how the intestinal ecosystem is altered and persistently shaped by transplantation-related factors and immunosuppression and how these changes correlate with clinical outcomes. We provide a perspective on leveraging microbiome insights, through biomarkers or microbiome-targeted interventions, to improve outcomes in solid-organ and stem-cell transplantation.

The microbiome is increasingly recognized as a key player in cancer pathogenesis and treatment response, acting through both local and systemic mechanisms. Microbial communities and their metabolites can directly influence drug metabolism, shape the immune landscape, and alter transcriptional and epigenetic programmes in the gut, systemically and in the tumour microenvironment. Emerging data support the potential of microbiome-targeted interventions (such as faecal microbiota transplantation, diet, prebiotics and probiotics) as adjuncts to conventional cancer therapies, with the goal of enhancing efficacy and reducing toxicity. This Review highlights the promise of the microbiome as a prognostic and predictive biomarker, a modifiable factor in cancer care and prevention, and a therapeutic target. We also discuss major knowledge gaps, limitations in current study designs, and the need for mechanism-guided, personalized strategies to advance clinical translation.

Different definitions of keystone taxa and functions agree that they have an outsized role in maintaining community composition, and thus, the keystone concept continues to attract attention even 50 years after its introduction. In this Perspective, we base our definition of microbial keystones on the original one to explore its implications and limitations. We review different mechanisms behind keystoneness, cover the strengths and weaknesses of current keystone prediction methods and present findings on keystones discovered in recent experiments. In addition, we suggest a new prediction method for keystones based on metabolic modelling. Finally, we discuss the role of keystones in community control strategies. Overall, the development of new prediction methods and the insights from recent experiments illustrate the continued relevance of the keystone concept for microbial communities.
