Nanoparticle triggered regulated necrosis (Homo sapiens)
Programmed cell death: regulated necrosis. During regulated necrosis, different stimuli are recognized or sensed by specific receptors on the cell surface or inside cells. The activation of the necrosome stimulates different signaling pathways leading to mitochondrial hyperpolarization, lysosomal membrane permeabilization, and generation of reactive oxygen species (ROS), leading to cellular disintegration. A recent study revealed that germanium nanoparticles trigger necrostatin-1-inhibitable cell death with a reduction of the mitochondrial membrane potential.
