Hypothetical model for the existence of various prion strains postulating that PrPsc carries a modification, for example carbohydrate residues, which varies from strain to strain and targets a particular subset of cells.

DEF

A theory explaining some biological effects of radiation on the basis that ionization, which occurs in a discrete volume(the target) within the cell, directly causes a lesion that later results in a physiological response to the damage at that location.

OBS

One, two or more hits (ionizing events within the target) may be necessary to elicit the response.
