Implementation of a responsible conduct of research education program at Duke University School of Medicine.

Academic medical centers rarely require of their research faculty and staff to participate in educational programs on the responsible conduct of research (RCR). There is also little published evidence of RCR programs addressing high-profile, internal cases of misconduct as a way of promoting deliberation and learning. In the wake of major research misconduct, Duke University School of Medicine (DUSoM) expanded its RCR education activities to include all DUSoM faculty and staff engaged in research.

Potentiation of P2RX7 as a host-directed strategy for control of mycobacterial infection.

is the leading worldwide cause of death due to a single infectious agent. Existing anti-tuberculous therapies require long treatments and are complicated by multi-drug-resistant strains. Host-directed therapies have been proposed as an orthogonal approach, but few have moved into clinical trials.

Macrophage Epithelial Reprogramming Underlies Mycobacterial Granuloma Formation and Promotes Infection.

Mycobacterium tuberculosis infection in humans triggers formation of granulomas, which are tightly organized immune cell aggregates that are the central structure of tuberculosis. Infected and uninfected macrophages interdigitate, assuming an altered, flattened appearance. Although pathologists have described these changes for over a century, the molecular and cellular programs underlying this transition are unclear.

Infection-Induced Vascular Permeability Aids Mycobacterial Growth.

Pathogenic mycobacteria trigger formation of organized granulomas. As granulomas mature, they induce angiogenesis and vascular permeability. Here, in a striking parallel to tumor pro-angiogenic signaling, we identify angiopoietin-2 (ANG-2) induction as an important component of vascular dysfunction during mycobacterial infection.
