Detailed Description
Statement
Reference

Cubn2E3-1 homozygous larval nephrocytes exhibit a decrease in the number of slit diaphragms in the cortical region, and are not strictly confined to the entrance of labyrinthine channels but are also found at internal ectopic positions; the subcortical region occupied by labyrinthine channels, clathrin-coated vesicles and pits, tubules, and α-vacuoles is less compact than in controls; the subcortical region seems to be occupied by membrane ingressions containing SD-like densities, suggesting elongated labyrinthine channels; vacuoles and mitochondria are regularly distributed throughout the cytoplasm instead of being confined to the transition zone; nuclei are displaced from their central position; and multilaminar structures are frequently observed.
