Long-Range Activation of Systemic Immunity through Peptidoglycan Diffusion in Drosophila
Figure 1
Infection of Drosophila males through the genitalia.
(A) A scanning electron microscopy image of the male genital plate (kindly provided by Jagadeeshan and Singh). Note the complex cuticular structures surrounding the anal (yellow) and genital (blue) openings. Scale bar = 200µm. See also Jagadeeshan and Singh [46]. (B) GI of males was performed by depositing about 30nL of bacteria or microbial products on the genital plate using a 200µL tip as illustrated.
