Figure 2. Expression pattern of selected G-protein coupled receptors in the airway system of Drosophila larvae.

Figure 2

Promotor-Gal4 lines of different G-protein coupled receptors were used to study their expression pattern in the airway system. The promoter of the OAMB receptor drives expression to terminal branches or cells (A overview, B intestine with terminal cell). The TyrR show higher expression in primary branches (C), the frizzled receptor is also predominantly found in these structures (D) octopamine/tyramine receptors drive expression in different parts of the airway system. The Oct2βR-Gal4 is primarily present in the dorsal trunks (A). The OAMB receptor can be observed in the primary airways (B). Especially the terminal cells located directly adjacent to different organ systems show a strong expression of this receptor (C). The OA2 receptor is also found predominantly in the primary airways (D). In contrast, the TyrRII (E), the DopR2 (F) and the OAR2 (G) show a broader expression pattern. Scale bars in A, C, D, E is 50 µm, in B, F 20 µm and in G 10 µm.
