Trimeric Tau Is Toxic to Human Neuronal Cells at Low Nanomolar Concentrations

Figure 4

Plots of height distribution of monomeric, dimeric, and trimeric fractions of rhTau 1N4R (a) and tau 2N4R (b). The height value of each particle was measured using Gwyddion. The numbers of particles falling in continuous size ranges were calculated and normalized into count percentages. The peak values give an approximate value for each tau species particle size. As expected, high-degree oligomers are larger than low-degree oligomers within the same isoform, and corresponding oligomeric aggregates from the longer isoform are larger than aggregates from the shorter isoform.
