Disruption treatments on two strains of Streptococcus thermophilus: Levels of lysis/permeabilisation of the cultures, and influence of treated cultures on the ripening profiles of Cremoso cheese
(Elsevier, 2019-05)
The influence of several disruption treatments on the viability and the release of intracellular enzymes of two strains of Streptococcus thermophilus (St1 and St2) was studied. In addition, the impact of the incorporation ...
The membranotropic activity of N-terminal peptides from the pore-forming proteins sticholysin I and II is modulated by hydrophobic and electrostatic interactions as well as lipid composition
(Indian Acad Sciences, 2011-12-01)
The sea anemone Stichodactyla helianthus produces two pore-forming proteins, sticholysins I and II (St I and St II). Despite their high identity (93%), these toxins exhibit differences in hemolytic activity that can be ...

Characterization of dual effects induced by antimicrobial peptides: Regulated cell death or membrane disruption
(Elsevier B.V., 2012-07-01)
Background: Some reports describe lysis mechanisms by antimicrobial peptides (AMPs), while others describe the activation of regulated cell death. in this study, we compare the cell death-inducing activities of four ...
Cytotoxic effects of crotamine are mediated through lysosomal membrane permeabilization
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Crotamine, one of the main toxic components of Crotalus durissus terrificus venom, is a small non-enzymatic basic polypeptide, which causes hind limb paralysis and necrosis of muscle cells. it is well-known that several ...
Pore Formation Triggered by Legionella spp. Is an Nlrc4 Inflammasome-Dependent Host Cell Response That Precedes Pyroptosis
(AMER SOC MICROBIOLOGY, 2010)
Legionella pneumophila, the etiological agent of Legionnaires disease, is known to trigger pore formation in bone marrow-derived macrophages (BMMs) by mechanisms dependent on the type IVB secretion system known as Dot/Icm. ...
Chlorogenic acid is a fungicide active against phytopathogenic fungi
(Academic Press Inc Elsevier Science, 2017-08)
Plants synthesize diverse types of secondary metabolites and some of them participate in plant protection against pathogen attack. These compounds are biodegradable and renewable alternatives, which may be envisaged for ...
Biophysical characterization and antitumor activity of synthetic Pantinin peptides from scorpion's venom
(2018-11-01)
Antimicrobial peptides have been extensively described as bioactive agents, mainly considering their selective toxicity towards bacteria but not to healthy mammalian cells. In past years, this class of compounds has been ...
