Background
Alternative splicing of exon 10 results in the expression of two groups of tau: three-repeat and four-repeat tau. Isoforms 2, 4, and 5 express three microtubule binding repeat domains (tau 3R) while isoforms 6, 7, and 8 express four microtubule binding repeat domains (tau 4R) (4). Expression of tau 3R and tau 4R in cells can be different in mild or pathological conditions. For example, tau 3R is preferentially expressed in Pick's disease (PiD) and corticobasal degeneration (CBD), while tau 3R and tau 4R are equally expressed in AD (5,6). The repeat-dependent tau has a different pattern of phosphorylation in different diseases, and also has the ability and patterns of aggregation (7-9).
