Immunomodulatory and Cytotoxic Properties of Enniatin B1 in Porcine Alveolar Macrophages

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT This study investigates the immunomodulatory effects of Enniatin B1 (ENNB1), an emerging mycotoxin, on porcine alveolar macrophages (PAMs), a species‐specific model relevant to human innate immunity. PAMs were exposed to increasing ENNB1 concentrations (0.5–6 μM) over 6, 24, and 48 h.

μ-calpain binds to lipid bilayers via the exposed hydrophobic surface of its Ca2+-activated conformation [PDF]

open access: yes, 2006
μ- and m-calpain are cysteine proteases requiring micro- and millimolar Ca2+ concentrations for their activation in vitro. Among other mechanisms, interaction of calpains with membrane phospholipids has been proposed to facilitate their activation by ...

The Mechanism of NLRP3 Inflammasome Activation and Its Roles in Chronic Rhinosinusitis

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT NLRP3 (NLR family pyrin domain containing 3) is one of the crucial receptors in pathogen recognition receptor (PRR) families which can recognize the pathogen‐associated molecular patterns (PAMPs) and the damage‐associated molecular patterns (DAMPs), thus triggering innate immune response. After NLRP3 activation, it recruits the adaptor protein

GCN2 in proteostasis: structural logic, signalling networks and disease

open access: yesThe FEBS Journal, EarlyView.
Threats to protein synthesis activate the kinase GCN2, initiating the integrated stress response (ISR). GCN2 is triggered by stalled ribosomes and uncharged tRNAs, which accumulate when amino acids are scarce. The ISR adjusts cellular physiology by promoting redox balance, protein quality control, and mitochondrial optimisation.

Inactivation of murine norovirus on a range of copper alloy surfaces is accompanied by loss of capsid integrity

open access: yes, 2015
Norovirus is one of the most common causes of acute viral gastroenteritis. The virus is spread via the fecal-oral route, most commonly from infected food and water, but several outbreaks have originated from contamination of surfaces with infectious ...
