Neutrophils are recruited to infected regions or web pages of injury based on a chemoattractant gradient (Borregaard, 2010; Kumar and Sharma, 2010). Recruited neutrophils may be activated by extracellular stimuli, resulting in the production of a number of reactive oxygen species (Dahlgren and Karlssson, 1999; Walther et al., 2000; Tiffany et al., 2001). It truly is a important aspect of resting neutrophils that they have to be activated for host defense. The activation of neutrophils could be induced by various various stimuli, which includes pathogen-derived molecules and several chemoattractants (Walther et al., 2000; Tiffany et al., 2001; Sabroe et al., 2003; Kobayashi, 2008). Among these, chemoattractants, such as various chemokines that regulate the activities of neutrophils, have received much interest over the final decade. These chemoattractants bind to particular cell surface receptors, that are coupled to pertussis toxin (PTX)-sensitive G-protein(s), resulting in intracellular Ca2+ mobilization, cell migration, exocytosis, adhesion, and generation of bioactive lipids andor reactive oxygen species (Walther et al., 2000; Tiffany et al., 2001; Kobayashi, 2008).

Within this study, we identified three novel peptides by screening a synthetic hexapeptide combinatorial library. The identified peptides GMMWAI, MMHWAM, and MMHWFM triggered an increase in intracellular Ca2+ within a concentration-dependent manner through phospholipase C activity in human neutrophils.
