Homeostasis-related glia-typical functions in T. marmoratus camera eyes. A Insect glia-typical genes such as stretchin-mick (strn-Mlck), myogialnin (myo), axotactin (axo), and tramtrack (ttk) are enriched in the SupCs, but the general insect glia marker reversed polarity (repo) is enriched in the retina. B The SupCs are enriched in immune response genes, including gram-negative bacteria binding protein 3 (gnbp3), limpet (lmpt), immune deficiency (imd), Toll-like receptor (tollo), defense repressor 1 (dnr1), and dorsal (dl). C SupC-enriched genes associated with blood–brain barrier (BBB) formation include pasiflora 2 (pasi2), fasciclin 3 isoform B (fas3), sinuous (sinu), and kune. D and E Genes required for potassium transport (inwardly rectifying potassium channel 2 (irk2) and acid-sensitive potassium channel 7 (task7)), sodium symport (rumpel/CG9657), chloride transport (chloride channels (clic and clc-c) and bestrophin (bes2)), amine transport (pathetic (path)), osmoregulation (serotonin receptor (5-ht2a), vacuolar H + ATPase (vha100-2), and osmotic stress response related gene inebriated (ine)) are enriched in the SupCs. The expression of aquaporin genes such as aqp, eglp4, prip, drip, and bib is not significantly different in the SupCs and retina
