Abstract Due to the cytotoxic effect of antimicrobial peptides (AMP) against several microorganism and tumor cells has been proposed their association with the immune system. However, just a few reports have shown this relationship. In this study, mice were treated with gomesin, a beta-hairpin AMP that exhibit high cytotoxicity against bacterial and tumor cells. Different effects in the immune system were observed, such as, decrease of CD3(+) in T lymphocytes (Control: 17.7 +/- 1.4%

Gomesin: 7.67 +/- 11.2%) and in hematopoietic progenitors and increase of hematopoietic stem cell (Control: 0.046 +/- 0.004%

Gomesin: 0.067 +/- 10.003%), B220(+) B lymphocytes (Control: 38.63 +/- 1.5%

Gomesin: 47.83 +/- 0.48%), and Mac-1(+)F4/80(+) macrophages (Control: 11.76 +/- 3.4%

Gomesin: 27.13 +/- 4.0%). Additionally, macrophage increase was accompanied by an increase of macrophage phagocytosis (Control 20.85 +/- 1.53

Gomesin 31.32 +/- 1 Geometric mean), interleukin 6 (Control: 47.24 +/- 1.9 ng/mL

Gomesin: 138.68 +/- 33.68 ng/mL) and monocyte chemoattractant protein-1 (Control: 0.872 +/- 0.093 ng/mL

Gomesin: 1.83 +/- 0.067 ng/mL). Thus, this report showed immunomodulatory activity of gomesin in the immune system of mice. (C) 2016 Elsevier Inc. All rights reserved.
