Effect of human defensins on lactobacilli and liposomes
(Wiley Blackwell Publishing, Inc, 2012-11)
Aims: To study the effect of human b-defensins (HBD-1 and HBD-2) on lactobacilli membranes as well as on liposomes prepared from purified bacterial lipids. Methods and Results: Lactobacillus delbrueckii subsp. bulgaricus ...
Interaction between the plant ApDef1 defensin and Saccharomyces cerevisiae results in yeast death through a cell cycle- and caspase-dependent process occurring via uncontrolled oxidative stress
(Elsevier Science, 2017-01)
Background Plant defensins were discovered at beginning of the 90s' however, their precise mechanism of action is still unknown. Herein, we studied ApDef1-Saccharomyces cerevisiae interaction. Methods ApDef1-S. cerevisiae ...
Microcin J25 inhibits ubiquinol oxidase activity of purified cytochrome bd-I from Escherichia coli
(Elsevier France-editions Scientifiques Medicales Elsevier, 2019-05)
Microcin J25 (MccJ25), an antimicrobial peptide, targets the respiratory chain but the exact mechanism by which it does so remains unclear. Here, we reveal that MccJ25 is able to inhibit the enzymatic activity of the ...
Cathelicidin modulates synthesis of Toll-like Receptors (TLRs) 4 and 9 in colonic epithelium
(2017-11)
Cathelicidin are innate antimicrobial peptides with broad immunomodulatory functions; however, their role in regulating intestinal defenses is not well characterized. This study aimed to investigate the role of cathelicidin ...
Potato snakin-1 gene enhances tolerance to Rhizoctonia solani and Sclerotinia sclerotiorum in transgenic lettuce plants
(Elsevier, 2018-10)
Snakin-1 is a cysteine-rich antimicrobial peptide (AMP) isolated from potato tubers, with broad-spectrum activity.
It belongs to the Snakin/GASA family, whose members have been studied because of their diverse roles ...
Cathelicidin bovine myeloid antimicrobial peptide (BMAP) 28 is involved in the inflammatory response against alpha-herpesviruses in the bovine nervous system
(Elsevier, 2020-06)
The role of the local innate immune response in the neuropathogenesis of bovine herpesvirus (BoHV) type 1 and 5 remains largely unknown. This study determined the gene transcriptional expression of relevant bovine ...
The arsenal of bioactive molecules in the skin secretion of urodele amphibians
(Frontiers Media, 2022-01)
Urodele amphibians (∼768 spp.), salamanders and newts, are a rich source of molecules with bioactive properties, especially those isolated from their skin secretions. These include pharmacological attributes, such as ...
Lactobacillus delbrueckii subsp. bulgaricus CRL 454 cleaves allergenic peptides of beta-lactoglobulin
(Elsevier, 2015-01)
Whey, a cheese by-product used as a food additive, is produced worldwide at 40.7 million tons per year.b-Lactoglobulin (BLG), the main whey protein, is poorly digested and is highly allergenic. We aimed to study the ...

Transgenic expression of plant-specific insert of potato aspartic proteases (StAP-PSI) confers enhanced resistance to Botrytis cinerea in Arabidopsis thaliana
(Pergamon-Elsevier Science Ltd, 2018-05)
The plant-specific insert of Solanum tuberosum aspartic proteases (StAP-PSI) has high structural similarity with NK-lysin and granulysin, two saposin-like proteins (SAPLIPs) with antimicrobial activity. Recombinant StAP-PSI ...
