Probable mechanisms of resistance to carcinogenic impacts and spontaneous tumours of long life span vertebrate species have been discussed. It has been suggested that this compatible with long life span mechanism is likely phagocyte elimination with involving DNA-protenkinase-dependent, wt p53 or/and wt p53-dependent signaling pathways also ligands for "Scavenger receptor" and "Toll-like receptors". The approaches to the experimental evidence of this hypothesis have been produced.
