Randomized trial investigating the utility of a liver tissue transcriptional biomarker in identifying adult liver transplant recipients not requiring maintenance immunosuppression.

The maintenance of stable allograft status in the absence of immunosuppression, known as operational tolerance, can be achieved in a small proportion of liver transplant recipients, but we lack reliable tools to predict its spontaneous development. We conducted a prospective, multi-center, biomarker-strategy design, immunosuppression withdrawal clinical trial to determine the utility of a predictive biomarker of operational tolerance. The biomarker test, originally identified in a patient cohort with high operational tolerance prevalence, consisted of a 5-gene transcriptional signature measured in liver tissue collected before initiating immunosuppression weaning.

Yin Yang 1 and guanine quadruplexes protect dopaminergic neurons from cellular stress via transmissive dormancy.

Neurons deploy diverse adaptive strategies to ensure survival and neurotransmission amid cellular stress. When these adaptive pathways are overwhelmed, functional impairment or neurodegeneration follows. Here we show that stressed neurons actively induce a state of transmissive dormancy as a protective measure.

Neutrophils enhance the clearance of systemic amyloid deposits in a murine amyloidoma model.

Introduction: Amyloid-specific antibodies have been shown to opsonize and enhance amyloid clearance in systemic amyloidosis mouse models. However, the immunological mechanisms by which amyloid is removed have not been clearly defined. Previous reports from preclinical studies suggest polymorphonuclear cells (, neutrophils) can affect amyloid removal.

A spatially explicit assessment of factors shaping attitudes toward African elephant conservation.

Conservation plans that explicitly account for the social landscape where people and wildlife co-occur can yield more effective and equitable conservation practices and outcomes. Yet, social data remain underutilized, often because social data are treated as aspatial or are analyzed with approaches that do not quantify uncertainty or address bias in self-reported data. We conducted a survey (questionnaires) of 177 households in a multiuse landscape in the Kenya-Tanzania borderlands.
