One potential source for rapid genesis of amyloid‐beta (Aβ) species after traumatic brain injury (TBI). A. Widespread damage to axons induces transport interruption and accumulation of amyloid precursor protein (APP) and the secretases, PS‐1 and BACE that can cleave it to form Aβ peptides within axonal swellings. B. Accumulating Aβ assembles into oligomers and protofibrils, that are (C) released into the brain when the axonal bulb is lysed. D. Free Aβ oligomers, protofibrils and developing fibrils may exert toxicity to the brain and/or form plaques that can be observed within hours after TBI.
