Immune cells as squatters

Contrary to previous belief, some blood cells stay in tissues for years


Human immune cells not only circulate in the blood, but can also occupy certain tissues and sometimes remain there for years. A research team led by immunologist Christina Zielinski discovered this phenomenon by examining patient samples after stem cell transplantation. In addition, the ...

Cancer: Study suggests that gut microbiome can provide prognosis for therapy

Possible correlation between success of cancer therapy and intestinal microbes


Cancer patients respond differently to therapies. The success of the classical treatment methods possibly depends on the composition of the microbiome in the gut. Study results obtained by researchers from Jena and Hong Kong point to that. For their study they investigated eight different types ...
