Lysozyme C-1; Lysozymes have primarily a bacteriolytic function; those in tissues and body fluids are associated with the monocyte-macrophage system and enhance the activity of immunoagents. Lyz1 is active against a range of Gram-positive and Gram-negative bacteria. Less effective than Lyz2 in killing Gram-negative bacteria. Lyz1 and Lyz2 are equally effective in killing Gram-positive bacteria; Belongs to the glycosyl hydrolase 22 family.

Angiogenin-4; Has bactericidal activity against E.faecalis and L.monocytogenes, but not against L.innocua and E.coli. Promotes angiogenesis (in vitro). Has low ribonuclease activity (in vitro). Promotes proliferation of melanoma cells, but not of endothelial cells or fibroblasts (in vitro).

Regenerating islet-derived protein 3-beta 16.5 kDa form; Bactericidal C-type lectin which acts against several intestinal Gram-positive and Gram-negative bacteria. Lacks antibacterial activity against S.typhimurium. May play a role in protection against infection with S.enteritidis by inhibiting its translocation from the gut lumen into intestinal tissues and further extraintestinal tissues.

Mucin-2; Coats the epithelia of the intestines, airways, and other mucus membrane-containing organs. Thought to provide a protective, lubricating barrier against particles and infectious agents at mucosal surfaces. Major constituent of both the inner and outer mucus layers of the colon and may play a role in excluding bacteria from the inner mucus layer.

Alpha-defensin 5; Probably contributes to the antimicrobial barrier function of the small bowel mucosa; Belongs to the alpha-defensin family.

Alpha-defensin-related sequence 1; Apparent precursor of a secreted, cationic, proline- and cysteine-rich peptide that contains Cys-Pro-Xaa repeats. Unlike cryptdin, the proposed mature peptide region lacks the structural motif characteristic of defensins. It may have microbicidal activities; Belongs to the alpha-defensin family.

Alpha-defensin 20; May have microbicidal activities; Belongs to the alpha-defensin family.

Myeloid differentiation primary response protein MyD88; Adapter protein involved in the Toll-like receptor and IL-1 receptor signaling pathway in the innate immune response. Acts via IRAK1, IRAK2, IRF7 and TRAF6, leading to NF- kappa-B activation, cytokine secretion and the inflammatory response. Increases IL-8 transcription. Involved in IL-18-mediated signaling pathway. Isoform 2 is defective in its ability to induce IRAK phosphorylation and NF- kappa-B activation and can function as a negative regulator of activation by IL-1 or lipopolysaccharide (LPS). Activates IRF1 resulting in it [...]
