Popis: Infectious pathogens that break through surface defences and reach underlying tissue or blood encounter an array of interior host defences. These fall basically into two classes: innate and adaptive defences. The innate system is the phylogenically older of the two branches and uses germline-encoded pattern-recognition receptors (PRR) to identify microbial invaders (Pugin et al. 1994). An example is CD14, a receptor for bacterial cell-wall components (CWCs), such as lipopolysaccharides (LPS) and lipoteichoic acids. CD14 recognises carbohydrate constituents commonly expressed on pathogens (Espevix et al. 1993; Zhang et al. 1994; Ulevitch and Tobias 1995; Cleveland et al. 1996) and signals “danger” to myeloid-lineage cells (Matzinger 1994).
