Stroke: Macrophages migrate from the blood

Macrophages are part of the innate immune system and essential for brain development and function. Using a novel method, scientists from Jena University Hospital, the University of Bonn and the Memorial Sloan Kettering Cancer Center in New York (USA) succeeded in visualizing macrophages that were formed in the bone marrow. In studies on mice, this technology enabled the researchers to observe that shortly after a stroke, numerous macrophages that had migrated from the blood begin to attack dead and adjacent healthy brain tissue. The results have now been published in the journal Nature Neuroscience.

Now, a new “Perspective” in The Journal of Infectious Diseases by NIAID Director Anthony S. Fauci, M.D., and other Institute officials summarizes recent progress in improved TB diagnostics, therapeutic regimens and prevention approaches that made 2019 a “banner year” for TB research.
