Metchnikowin (Mtk) encodes an antifungal peptide that is secreted from the fat body during the systemic immune response, and is produced by various epithelia. Its expression is regulated at the transcriptional level by the immune deficiency and/or Toll pathways.

Immune-induced peptide 16; Attacin-C (AttC) encodes an immune inducible peptide that shows homology to antibacterial peptides having activity against Gram-negative bacteria; Belongs to the attacin/sarcotoxin-2 family.

Attacin-A (AttA) encodes an antibacterial peptide with activity against Gram-negative bacteria. It is expressed in the fat body and various epithelia under the regulation of the immune deficiency and, to a lesser extent, Toll pathways; Belongs to the attacin/sarcotoxin-2 family.

Drosocin (Dro) encodes an o-Glycosylated antibacterial peptide with activity against Gram-negative and Gram-positive bacteria. It is expressed in the fat body during the systemic immune response and is expressed in various epithelia. The expression of Dro is regulated at the transcriptional level mostly by the immune deficiency pathway; Belongs to the drosocin 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 [...]

Protein immune deficiency; Essential for the imd/NF-kappa-B (Imd) humoral and epithelial immune response to Gram-negative bacteria. Functions as an adapter protein that transduces immunity signals from the activation of pathogen recognition receptors (PRRs) by bacterial infection to the Imd signaling pathway. Binding of diaminopimelic acid-type (DAP-type) bacterial peptidoglycans (PGN) causes multimerization or clustering of PGRP receptors which activate the Imd cascade probably by recruiting imd, Fadd and Dredd to the receptor complex. Once in proximity, Dredd cleaves imd in a Fadd-de [...]

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

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.

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.
