Cecropin-A1; Cecropin A1 (CecA1) encodes an antibacterial peptide with activity against Gram-negative bacteria. It is expressed in the fat body during the systemic immune response and in various epithelia, and it is regulated at the transcriptional level, mostly by the immune deficiency pathway; Belongs to the cecropin family.

Nuclear factor NF-kappa-B p110 subunit; Plays a key role in the humoral immune response. Rel-p68 subunit translocates to the nucleus where it binds to the promoter of the Cecropin A1 gene and probably other antimicrobial peptide genes. I-kappa-B kinase complex (IKKbeta and key) and PGRP-LC are essential signaling components in transmitting the lipopolysaccharide (LPS) signal leading to cact degradation for NF-kappa-B (rel) activation. Part of a Toll-related receptor pathway that functions in the apoptosis of unfit cells during cell competition. May be part of a NF-kappa-B and Tollo sig [...]

Defensin (Def) encodes an antibacterial peptide with activity against Gram-positive bacteria. It is induced in the fat body during the systemic immune response and is expressed in various epithelia. The expression of Def is regulated at the transcriptional level by both the immune deficiency and Toll pathways; Belongs to the invertebrate defensin family. Type 1 subfamily.

Cecropin-C; Cecropin C (CecC) encodes an antibacterial peptide with activity against Gram-negative bacteria. It is strongly expressed at the pupal stage.

Embryonic polarity protein dorsal; Embryonic developmental protein. The lateral or ventral identity of a cell depends upon the concentration of this protein in its nucleus during the blastoderm stage. A morphogenetic protein that specifically binds to the kappa B-related consensus sequence 5'- GRGAAAANCC-3', located in the enhancer region of zygotic genes such as Zen, Twist, Snail and Decapentaplegic. Mediates an immune response in larvae. Part of a signaling pathway involving NF- kappa-B and Toll-related receptors, that functions in the apoptosis of unfit cells during cell competition [...]

Cecropin-B; Cecropin B (CecB) encodes an helicoidal antibacterial peptide with activity against Gram-negative bacteria. It is mostly expressed at the pupal stage; Belongs to the cecropin family.

Bomanin-1; Secreted immune-induced peptide induced by Toll signaling. Has a role in resistance to bacterial and fungal infections. Has no activity against the fungus C.glabrata in vitro.

Drosomycin; Possesses antifungal activity and is active against a relatively broad spectrum of filamentous fungi. It inhibits spore germination at high concentrations and at low concentrations delays growth of hyphae which subsequently exhibit abnormal morphology. Spz C-106 in the hemolymph controls expression of the antifungal peptide by acting as a ligand of Tl and inducing an intracellular signaling pathway. Part of a psh-dependent Toll pathway, which may function in activating the systematic immune response in response to localized melanization of the tracheal system.

Myd88 (Myd88) encodes an adaptor protein involved in in the Toll pathway functioning downstream of the product of Tl and upstream of the product of tub. Toll pathway is a signaling cascade that plays a key role in various developmental and immune processes, notably embryonic dorsoventral patterning and regulation of antimicrobial peptides.
