(A) Representative images showing EV release from the tail at the initial imaging (0 hr) and the second imaging (1 hr) while the animals were mounted on slides, in wild-type, unc-13, and unc-31 males.
(B) Schematic diagram depicts the functional roles of UNC-13 and UNC-31 in synaptic vesicle- and dense core vesicle-mediated neuronal transmission in the axon. (C) Quantification of EV release from the tail at the initial imaging (0 hr) and second imaging (1 hr) in wild-type, unc-13, and unc-31 males. The scatter plot with lines indicates the mean ± SEM. Each data point represents the total EV count released by an individual C. elegans male. 12-15 animals were imaged for each genotype. Statistical analysis was performed by two-way ANOVA with Bonferroni correction. ns denotes not significant, * denotes p < 0.05, and ** denotes p < 0.01.
