Figure 2. SV accumulation in the Caps1 cKO presynapse.
(A) Representative images of presynaptic boutons in the CA3–CA1 stratum radiatum in control and Caps1 cKO mice. The presynaptic bouton is coloured in purple (scale bar: 200 nm). (B) Number of SVs in control and Caps1 cKO synapses; n = 48 and 51 synapses for control and Caps1 cKO, respectively. ***P < 0.001, Student’s t-test. (C) The area of the presynapse in control and Caps1 cKO synapses; n = 48 and 51 synapses for control and Caps1 cKO, respectively. P = 0.14, Student’s t-test. (D) Cumulative frequency of active zone length in control and Caps1 cKO synapses; n = 49 and 88 active zones for control and Caps1 cKO, respectively. P = 0.33, Kolmogorov–Smirnov test. (E) Cumulative frequency of PSD length in control and Caps1 cKO synapses; n = 49 and 86 PSDs for control and Caps1 cKO, respectively. P = 0.61, Kolmogorov–Smirnov test.
