CLEC4E (also called Mincle or CLECSF9) is a C-type lectin receptor (CLR) expressed in activated macrophages and dendritic cells (DCs) in response to several inflammatory stimuli, including LPS, TNF, IL6, IFN-gamma and cellular stresses (Matsumoto et al. 1999). Like the other activating receptors in the Dectin-2 family, CLEC4E is coupled with the FCERG (High affinity immunoglobulin epsilon receptor subunit gamma) to transduce intracellular signalling (Yamasaki et al. 2008). CLEC4E possesses a typical carbohydrate recognition domain (CRD) containing an EPN (Glu-Pro-Asn) motif which is capable of recognising several types of carbohydrates, particularly those containing alpha-mannose. CLEC4E can recognise fungal (Candida albicans and Malassezia), mycobacterial (trehalose-6,6?-dimycolate (TDM)) and necrotic cell ligands implicating this receptor in anti-microbial immunity and homeostasis (Schoenen et al. 2010, Yamasaki et al. 2009, Graham & Brown. 2009).
