The first four cells in each line are roughers and the last five are
scavenger cells. The rougher concentrate (10-15% Cu) reports to the cleaning circuit.
He and his colleagues verified that bacterial products stimulate the TH1 response and that this response involves roving
scavenger cells called macrophages.
Two mechanisms of secondary injury are being studied, including (1) the activation in nerve cells of self-digesting enzymes by increases of calcium levels within the cells after ischemia and (2) the role of free radicals --such as peroxides generated by astrocytes and macrophages (
scavenger cells)--in promoting neuronal damage.
For T-cells that actually leave the blood stream and enter the brain tissue, macrophages (the large
scavenger cells found throughout the body) can play this role.
"The clinical endpoint is immediate epidermal whitening of tattooed skin." The process causes transdermal elimination; some of it flows into the lymphatic system, while the rest undergoes rephagocytosis by dermal
scavenger cells.
