Shiga toxin-producing Escherichia coli (STEC) infections pose a significant public health challenge, characterized by severe complications including hemolytic uremic syndrome (HUS) due to Shiga toxin (Stx) production. Current therapeutic approaches encounter a critical limitation, as conventional antibiotic treatment is contraindicated due to its propensity to trigger bacterial SOS response and subsequently enhance Stx production, which increases the likelihood of developing HUS in antibiotic-treated patients. The lack of effective, safe therapeutic options has created an urgent need for alternative treatment strategies for STEC infections.

The regular workshops held by the Center for Alternatives to Animal Testing (CAAT) on biology-inspired microphysiological systems (MPS) taking place every four years, have become a reliable measure to assess fundamental scientific, industrial and regulatory trends for translational science in the MPS-field from a bird's eye view. The 2023 workshop participants at that time concluded that the technology as used within academia has matured significantly, underlined by the broad use of MPS and the steadily increasing number of high quality research publications - yet, broad industry adoption of MPS has been slow, despite strong interest. Academic research using MPS primarily aims to accurately recapitulate human biology in MPS-based organ models in areas where traditional models have been lacking key elements of human physiology, thereby enabling breakthrough discoveries for life sciences.

A data-driven latent variable approach to validating the research domain criteria framework.

Nat Commun

January 2025

Department of Psychiatry & Behavioral Sciences, School of Medicine, Stanford University, Stanford, CA, USA.

Despite the widespread use of the Research Domain Criteria (RDoC) framework in psychiatry and neuroscience, recent studies suggest that the RDoC is insufficiently specific or excessively broad relative to the underlying brain circuitry it seeks to elucidate. To address these concerns, we employ a latent variable approach using bifactor analysis. We examine 84 whole-brain task-based fMRI (tfMRI) activation maps from 19 studies with 6192 participants.

A wealth of research focused on African American populations has connected rs2814778-CC ("Duffy-null") to decreased neutrophil (neutropenia) and leukocyte counts (leukopenia). While it has been proposed that this variant is benign, prior studies have shown that the misinterpretation of Duffy-null associated neutropenia and leukopenia can lead to unnecessary bone marrow biopsies, inequities in cytotoxic and chemotherapeutic treatment courses, under-enrollment in clinical trials, and other disparities. To investigate the phenotypic correlates of Duffy-null status, we conducted a phenome-wide association study (PheWAS) across more than 1,400 clinical conditions in All of Us, the Vanderbilt University Medical Center's Biobank, and the Million Veteran Program.

Nr4a1 and Nr4a3 redundantly control clonal deletion and contribute to an anergy-like transcriptome in auto-reactive thymocytes to impose tolerance in mice.

Nat Commun

January 2025

Division of Rheumatology, Rosalind Russell and Ephraim P. Engleman Arthritis Research Center, Department of Medicine, University of California, San Francisco, CA, 94143, USA.

The Nr4a nuclear hormone receptors are transcriptionally upregulated in response to antigen recognition by the T cell receptor (TCR) in the thymus and are implicated in clonal deletion, but the mechanisms by which they operate are not clear. Moreover, their role in central tolerance is obscured by redundancy among the Nr4a family members and by their reported functions in Treg generation and maintenance. Here we take advantage of competitive bone marrow chimeras and the OT-II/RIPmOVA model to show that Nr4a1 and Nr4a3 are essential for the upregulation of Bcl2l11/BIM and thymic clonal deletion by self-antigen.
