Images of monocytes in the brain after a heart attack and schematic of the findings. Microscopy images of monocytes in the brain of a mouse after a heart attack. Schematic of hypothesized mechanism: after a heart attack, monocytes are released from the bone marrow and recruited to the brain where they produce TNF to increase sleep which limits stress signaling to the heart and promotes heart healing and recovery.
