Immunolocalization of AeAmt2 in the anal papillae of A. aegypti larvae. Representative paraffin-embedded cross sections of anal papillae showing immunoreactivity for: (A,E) AeAmt2 (red), (B) the V0 subunit of V-type H+ ATPase (VA, green), (F) Na+-K+-ATPase (NKA, green), and (C,G) nuclei staining with DAPI (blue). (D) Merged image of AeAmt2, VA, and DAPI, and (H) merged image of AeAmt2, NKA, and DAPI. White arrows indicate areas with nuclei, where separation of the apical and basolateral membranes is observed. Cross sections of anal papillae in brightfield (BF) corresponding to (I) panels (A–D) and (J) panels (E–H), demonstrating the apical (solid arrows) and basolateral (dashed arrows). (K) Control cross section of anal papillae (primary antibodies omitted). Scale bars (A–K): 20 μM.
