A new study suggests the leprosy bacterium can reprogram one type of nervous system cell to a stem cell-like state and use it to infiltrate other tissues in the body. Here, reprogrammed cells (green) fuse with and become skeletal muscles (red), spreading infection as they go. Cell nuclei are shown in blue.
