Both mannose-binding lectin (MBL) and ficolins are lectins, that circulate in plasma as oligomers of structural subunits. Each subunit is composed of three identical peptides and contains an amino-terminal cysteine-rich region, a collagen-like domain, a neck region and a carboxy-terminal carbohydrate-binding domain. However, the carbohydrate-binding domains of MBL and ficolins are quite different. A carbohydrate-recognition domain (CRD) is in MBL and a fibrinogen-like domain is in ficolins [Holmskov U et al 2003; Endo Y et al 2006; Thiel S and Gadjeva M 2009]. MBL recognizes certain carbohydrates such as mannose and GlcNAc. Mammalian ficolins like MBL possess carbohydrate-binding activity. Different ficolins have distinct recognition specificities [Matsushita M et al 1996; Lu J and Le Y 1998; Gout E et al 2009].

Mammals usually possess two MBL genes and two or three ficolin genes, but only one of each has been found in the chicken genome. Several studies investigated the function of chicken MBL upon avian viral infections with infectious laryngotracheitis virus (ILTV), infectious bursal disease virus (IBDV) and infectious bronchitis virus (IBV) [Nielsen OL et al 1998, 1999; Laursen SB and Nielsen OL 2000; Juul-Madsen HR et al 2003, 2007]. Similar to mammals, chickens produce MBL in the hepatocytes, secrete it into the blood, and upregulate the production during acute stages of virus infections. The serum concentration of chicken MBL increased two- to three-fold in virus-infected chickens compared with noninfected controls, indicating that chicken MBL is a minor acute phase mediator. Chicken MBL was also reported to mediate host response against bacterial infection such as Pasteurella multocida [Schou TW et al 2010]. The ability of chicken MBL to activate the complement cascade was tested in a heterologous system by deposition of human C4 on the chicken MBL:MASP complex in response to infection with avian IBV. The complement activation was directly associated with the concentration of MBL in serum [Laursen SB and Nielsen OL 2000; Juul-Madsen HR et al 2003, Norup LR and Juul-Madsen HR 2007].
