The week of November 12th was exciting with the 43rd Union World Conference, the WGND Annual Meeting (will be posting presentations soon), and the Stop TB Coordinating Board Meeting. Included are some news highlights and a listing of webcasts of interesting and presentations relevant for TB drug development and research.
During the “Cure All: A briefing on the status of the most promising new TB drugs research” sponsored by the Critical Path to New TB Drug Regimens (CPTR) on Monday, March 19, Dr. Mel Spigelman, CEO & President, of TB Alliance announced the launch of the NC002 trial, a combination drug trial that establishes a new pathway to TB and multi-drug resistant TB treatment. The meeting also involved high-level officials from U.S. agencies that support TB research including Anthony Fauci (Director, NIAID/NIH), Janet Woodcock (Director, CDER/FDA), and Robert Clay (Deputy Assistant Administrator, Global Health Bureau/USAID).
This week, we provide an brief overview of research supported by CNRS, INSERM, Institut Pasteur and other donors providing new evidence of the role of Zinc in the body’s immune response to intracellular infection by M.tb. and the microbe’s strategy to subvert this defense. Additional links to TB R&D news are included.
In this week’s article, potential cellular biomarkers are explored in the mouse model with three potential markers: PD-1 and TIM-3 on CD8 T cells and KIRG-1 on both CD4 and CD8 T cells. The search for validated biomarkers that can predict treatment success has been a difficult one. The focus of much of the research on biomarkers has been on serum markers, because of practical reasons and considerations of use in resource-limited settings. Henao-Tamayo, et al., took a different focus looking at markers on the surface of lung T cells. Additional links to TB R&D News are included.
