Identification of calcium-binding proteins associated with the human sperm plasma membrane [PDF]

open access: yes, 2010
Background The precise composition of the human sperm plasma membrane, the molecular interactions that define domain specific functions, and the regulation of membrane associated proteins during the capacitation process, still remain to be fully ...

A common response to common danger? Comparison of animal and plant signaling pathways involved in cadmium sensing

open access: yesJournal of Cell Communication and Signaling, Volume 6, Issue 4, Page 191-204, December 2012., 2012
Abstract Exposure to cadmium results in disturbances in cell homeostasis in all living organisms. The first response to stress factors, including cadmium, is activation of signal transduction pathways that mobilize cell defense mechanisms. The aim of this review is a comparison between the signaling network triggered by Cd in plants and animals ...

Differential IL-1β secretion by monocyte subsets is regulated by Hsp27 through modulating mRNA stability. [PDF]

open access: yes, 2016
Monocytes play a central role in regulating inflammation in response to infection or injury, and during auto-inflammatory diseases. Human blood contains classical, intermediate and non-classical monocyte subsets that each express characteristic patterns ...

Inhibition of Maitotoxin‐Induced Ca2+ Influx in Rat Glioma C6 Cells by Brevetoxins and Synthetic Fragments of Maitotoxin [PDF]

open access: yesJournal of Neurochemistry, 1998
Abstract: 45Ca2+ influx in rat glioma C6 cells induced by 0.3 nM maitotoxin (MTX) was markedly inhibited by brevetoxin A (PbTx1) and brevetoxin B (PbTx2), with EC50 values of 16 and 13 µM, respectively. This inhibition was observed immediately after addition of MTX when monitored with fura‐2, which suggests that PbTx2 directly blocks the action of MTX.

Modulating P2X7 Receptor Signaling during Rheumatoid Arthritis: New Therapeutic Approaches for Bisphosphonates

open access: yesJournal of Osteoporosis, Volume 2012, Issue 1, 2012., 2012
P2X7 receptor‐mediated purinergic signaling is a well‐known mechanism involved in bone remodeling. The P2X7 receptor has been implicated in the pathophysiology of various bone and cartilage diseases, including rheumatoid arthritis (RA), a widespread and complex chronic inflammatory disorder. The P2X7 receptor induces the release into the synovial fluid

Maitotoxin, a Ca2+ channel activator candidate.

open access: yesJournal of Biological Chemistry, 1982
Effects of maitotoxin, the most potent marine toxin, were studied using a rat pheochromocytoma cell line, PC12h. A low concentration (10(-8) g/ml) of maitotoxin induced a profound increase in CA2+ influx into PC12h cells and the Ca2+-dependent release of [3H]norepinephrine from them.

Opinion of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) on the risks to human health associated with the proliferation of Ostreopsis spp. on the Basque coast

open access: yesFood Risk Assess Europe, Volume 3, Issue 2, April 2025.
Abstract In France, the presence of marine microalgae of the genus Ostreopsis has been identified repeatedly on the Mediterranean coast for several years, whereas on the French Basque coasts its presence is much more recent. In the summers of 2021 and 2022, major Ostreopsis flowering episodes were reported on the Basque coast, resulting in several ...

Role of the Inflammasome, IL‐1β, and IL‐18 in Bacterial Infections

open access: yesThe Scientific World Journal, Volume 11, Issue 1, Page 2037-2050, 2011., 2011
The inflammasome is an important innate immune pathway that regulates at least two host responses protective against infections: (1) secretion of the proinflammatory cytokines IL‐1β and IL‐18 and (2) induction of pyroptosis, a form of cell death. Inflammasomes, of which different types have been identified, are multiprotein complexes containing pattern

Addressing the safety of new food sources and production systems

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 23, Issue 3, May 2024.
Abstract New food sources and production systems (NFPS) are garnering much attention, driven by international trade, changing consumer preferences, potential sustainability benefits, and innovations in climate‐resilient food production systems. However, NFPS can introduce new challenges for food safety agencies and food manufacturers.

The role of the inflammasome in cellular responses to toxins and bacterial effectors [PDF]

open access: yes, 2018
Invading pathogens are recognized by mammalian cells through dedicated receptors found either at the cell surface or in the cytoplasm. These receptors, like the trans-membrane Toll-like Receptors (TLR) or the cytosolic Nod-like Receptors (NLR), initiate ...
