Hijacking the Host Defenses Gives Bacteria an Advantage

A metabolic switch in microbe-fighting macrophages signals bacteria to convert them to hotels with amenities 

cells that remember their identity

Cancer cells turn out to have memories. But these are unreliable and can end up causing trouble

immune cells in cancer

A possible cause for cancer resistance to immunotherapy could be reversed

When the NXF1 gene functions properly (left), RNA molecules (orange dots) of a particular single-exon gene are exported from the nucleus (purple) into the cytoplasm; when the NXF1 is silenced (right), the RNAs are largely stuck within the nucleus

Cells use two separate routes to export RNA out of the nucleus
