Abstract
OBJECTIVE The objectives of this study were to describe poisonings occurring in older or disabled patients residing in structured living facilities, identify risk factors, and propose preventive measures. METHOD This was a prospective and observational study, covering all cases of poisoning occurring in structured living facilities in the Brittany region of France. All calls were received at the Grand Ouest Poison Control Centre (PCC) of Angers and were recorded from 1 February 2019 to 31 January 2020. The clinical severity of the poisonings was assessed using the Poisoning Severity Score (PSS). Clinical severity was compared by univariate and multivariate analyses using the following dependent variables: PSS score < 2 and PSS ≥ 2. RESULTS This study included 158 residents with a median age of 83 years (5-116 years old). The average number of residents supervised by a member of the supervisory staff was 11 (+/-10.7). The substance ingested was a personal hygiene product or a cleaning product in 48% and 25% of cases, respectively. The most frequently ingested product was a bar of soap (n = 20). All moderate to severe cases (4.6%, n = 8 including one death) occurred in residents with dementia living in nursing homes for elderly patients, and 9% of residents required hospital treatment. In more than 50% of cases (n = 83), the product was provided by the facility and in 23% (n = 40), it was brought in by the family. Ingestion of a bar of soap or a product brought in by the family was significantly associated with higher poisoning severity (PSS ≥ 2). After adjustment for age, sex and the number of residents per supervisor, the severity of poisoning was significantly greater after ingestion of a bar of soap (OR = 12.33, CI95 [2.12, 71.63], p = 0.005). CONCLUSION Older adults residing in medical facilities who have a history of dementia and/or cognitive impairment are more at risk of non-medicinal product poisoning. Clinical severity and the hospitalisation rate were greater when bar soap was ingested.

Abstract
Amphotericin B (AmB) belongs to a group of polyene antibiotics commonly used in the treatment of systemic mycotic infections. A widely accepted mechanism of action of AmB is based on the formation of an oligomeric pore structure within the plasma membrane (PM) by interaction with membrane sterols. Although AmB binds preferentially to ergosterol, it can also bind to cholesterol in the mammalian PM and cause severe cellular toxicity. The lipid content and its lateral organization at the cell PM appear to be significant for AmB binding. Several ATP-binding cassette (ABC) transporters, including ABCA1, play a crucial role in lipid translocation, cholesterol redistribution and efflux. Here, we demonstrate that cells expressing ABCA1 are more resistant to AmB treatment, while cells lacking ABCA1 expression or expressing non-active ABCA1MM mutant display increased sensitivity. Further, a FLIM analysis of AmB-treated cells reveals a fraction of the antibiotic molecules, characterized by relatively high fluorescence lifetimes (> 6 ns), involved in formation of bulk cholesterol-AmB structures at the surface of ABCA1-expressing cells. Finally, lowering the cellular cholesterol content abolishes resistance of ABCA1-expressing cells to AmB. Therefore, we propose that ABCA1-mediated cholesterol efflux from cells induces formation of bulk cholesterol-AmB structures at the cell surface, preventing AmB cytotoxicity.

Abstract
The neutrophilic serine protease proteinase 3 (PR3) is involved in inflammation and immune response and thus appears as a therapeutic target for a variety of infectious and inflammatory diseases. Here we combined kinetic and molecular docking studies to increase the potency of peptidyl-diphenyl phosphonate PR3 inhibitors. Occupancy of the S1 subsite of PR3 by a nVal residue and of the S4-S5 subsites by a biotinylated Val residue as obtained in biotin-VYDnVP(O-C6H4-4-Cl)2 enhanced the second-order inhibition constant kobs/[I] toward PR3 by more than 10 times ( kobs/[I] = 73000 ± 5000 M-1 s-1) as compared to the best phosphonate PR3 inhibitor previously reported. This inhibitor shows no significant inhibitory activity toward human neutrophil elastase and resists proteolytic degradation in sputa from cystic fibrosis patients. It also inhibits macaque PR3 but not the PR3 from rodents and can thus be used for in vivo assays in a primate model of inflammation.

Abstract
Cathepsin C (CatC) is a tetrameric cysteine dipeptidyl aminopeptidase that plays a key role in activation of pro-inflammatory serine protease zymogens by removal of a N-terminal pro-dipeptide sequence. Loss of function mutations in the CatC gene is associated with lack of immune cell serine protease activities and cause Papillon-Lefèvre syndrome (PLS). Also, only very low levels of elastase-like protease zymogens are detected by proteome analysis of neutrophils from PLS patients. Thus, CatC inhibitors represent new alternatives for the treatment of neutrophil protease-driven inflammatory or autoimmune diseases. We aimed to experimentally inactivate and lower neutrophil elastase-like proteases by pharmacological blocking of CatC-dependent maturation in cell-based assays and in vivo. Isolated, immature bone marrow cells from healthy donors pulse-chased in the presence of a new cell permeable cyclopropyl nitrile CatC inhibitor almost totally lack elastase. We confirmed the elimination of neutrophil elastase-like proteases by prolonged inhibition of CatC in a non-human primate. We also showed that neutrophils lacking elastase-like protease activities were still recruited to inflammatory sites. These preclinical results demonstrate that the disappearance of neutrophil elastase-like proteases as observed in PLS patients can be achieved by pharmacological inhibition of bone marrow CatC. Such a transitory inhibition of CatC might thus help to rebalance the protease load during chronic inflammatory diseases, which opens new perspectives for therapeutic applications in humans.

Abstract
Due to the intrinsic molecular Brownian agitation within plasma membrane and the vast diversity of membrane components, it is expected that the plasma membrane organization is highly heterogeneous with the formation of local complex multicomponent assemblies of lipids and proteins on different time scales. Still, deciphering this lateral organization on living cells and on the appropriate length and temporal scales has been challenging but is crucial to advance our knowledge on the biological function of the plasma membrane. Among the methodological developments based on biophotonics, the spot variation FCS (svFCS), a fluorescent correlation spectroscopy (FCS)-based method, has allowed the significant progress in the characterization of cell membrane lateral organization at the suboptical level, including to providing compelling evidence for the in vivo existence of lipid-dependent nanodomains. The aim of this chapter is to serve as a guide for setting and applying the svFCS methodology to study the plasma membrane of both adherent and nonadherent cell types.

Abstract
The cysteine protease cathepsin C (CatC) activates granule-associated proinflammatory serine proteases in hematopoietic precursor cells. Its early inhibition in the bone marrow is regarded as a new therapeutic strategy for treating proteolysis-driven chronic inflammatory diseases, but its complete inhibition is elusive in vivo Controlling the activity of CatC may be achieved by directly inhibiting its activity with a specific inhibitor or/and by preventing its maturation. We have investigated immunochemically and kinetically the occurrence of CatC and its proform in human hematopoietic precursor cells and in differentiated mature immune cells in lung secretions. The maturation of proCatC obeys a multistep mechanism that can be entirely managed by CatS in neutrophilic precursor cells. CatS inhibition by a cell-permeable inhibitor abrogated the release of the heavy and light chains from proCatC and blocked ∼80% of CatC activity. Under these conditions the activity of neutrophil serine proteases, however, was not abolished in precursor cell cultures. In patients with neutrophilic lung inflammation, mature CatC is found in large amounts in sputa. It is secreted by activated neutrophils as confirmed through lipopolysaccharide administration in a nonhuman primate model. CatS inhibitors currently in clinical trials are expected to decrease the activity of neutrophilic CatC without affecting those of elastase-like serine proteases.

Abstract
Newborns and infants present a higher susceptibility to infection than adults, a vulnerability associated with deficiencies in both the innate and adaptive immune systems. Innate immune receptors are sensors involved in the recognition and elimination of microbes that play a pivotal role at the interface between innate and adaptive immunity. Pentraxin 3 (PTX3), the prototypic long pentraxin, is a soluble pattern recognition receptor involved in the initiation of protective responses against selected pathogens. Because neonates are generally resistant to these pathogens, we suspected that PTX3 may be provided by a maternal source during the early life times. We observed that human colostrum contains high levels of PTX3, and that mammary epithelial cell and CD11b(+) milk cells constitutively produce PTX3. Interestingly, PTX3 given orally to neonate mice was rapidly distributed in different organs, and PTX3 ingested during lactation was detected in neonates. Finally, we observed that orally administered PTX3 provided protection against Pseudomonas aeruginosa lung infection in neonate mice. Therefore, breastfeeding constitutes, during the early life times, an important source of PTX3, which actively participates in the protection of neonates against infections. In addition, these results suggest that PTX3 might represent a therapeutic tool for treating neonatal infections and support the view that breastfeeding has beneficial effects on the neonates' health.

Abstract
The prototypic long pentraxin PTX3, a soluble pattern recognition receptor, plays an important role in innate defense against selected pathogens by favoring their elimination and the initiation of protective responses. PTX3 has notably beneficial effects in mice infected with Aspergillus fumigatus and Pseudomonas aeruginosa. Cystic fibrosis (CF), a severe inherited autosomal recessive disease, is characterized by recurrent lung infections, especially by these two pathogens. We thus hypothesized that the status of PTX3 may be altered in CF patients. Level and integrity of PTX3 were analyzed in the sputum samples from 51 CF patients and 7 patients with chronic obstructive pulmonary disease (COPD). The levels of PTX3 were increased in serums from CF patients, but low in their respiratory secretions. PTX3 concentrations in sputum samples were dramatically lower in CF patients than in COPD patients. The low concentration of PTX3 resulted from a proteolysis cleavage by elastase and A. fumigatus proteases. Interestingly, the N-ter domain of PTX3, involved in protection against A. fumigatus, is preferentially degraded by these proteases. These results indicate that the selective proteolysis of PTX3 in the CF lung may explain, in part, the recurrent lung infections by PTX3-sensitive pathogens in CF patients.

Abstract
The transport of specific molecules across lipid membranes is an essential function of all living organisms and a large number of specific transporters have evolved to carry out this function. The largest transporter gene family is the ATP-binding cassette (ABC) transporter superfamily. These proteins translocate a wide variety of substrates including sugars, amino acids, metal ions, peptides, and proteins, and a large number of hydrophobic compounds and metabolites across extra- and intracellular membranes. ABC genes are essential for many processes in the cell, and mutations in these genes cause or contribute to several human genetic disorders including cystic fibrosis, neurological disease, retinal degeneration, cholesterol and bile transport defects, anemia, and drug response. Characterization of eukaryotic genomes has allowed the complete identification of all the ABC genes in the yeast Saccharomyces cerevisiae, Drosophila, and C. elegans genomes. To date, there are 48 characterized human ABC genes. The genes can be divided into seven distinct subfamilies, based on organization of domains and amino acid homology. Many ABC genes play a role in the maintenance of the lipid bilayer and in the transport of fatty acids and sterols within the body. Here, we review the current knowledge of the human ABC genes, their role in inherited disease, and understanding of the topology of these genes within the membrane.

Abstract
The identification of defects in ABCA1 as the molecular basis of Tangier disease has highlighted its crucial role in the loading with phospholipids and cholesterol of nascent apolipoprotein particles. Indeed the expression of ABCA1 affects apolipoprotein A-I (apoA-I)-mediated removal of lipids from cell membranes, and the possible role of ABCA1 as an apoA-I surface receptor has been recently suggested. In the present study, we have investigated the role of the ABCA1 transporter as an apoA-I receptor with the analysis of a panel of transfectants expressing functional or mutant forms of ABCA1. We provide experimental evidence that the forced expression of a functional ABCA1 transporter confers surface competence for apoA-I binding. This, however, appears to be dependent on ABCA1 function. Structurally intact but ATPase-deficient forms of the transporter fail to elicit a specific cell association of the ligand. In addition the diffusion parameters of membrane-associated apoA-I indicate an interaction with membrane lipids rather than proteins. These results do not support a direct molecular interaction between ABCA1 and apoA-I, but rather suggest that the ABCA1-induced modification of the lipid distribution in the membrane, evidenced by the phosphatidylserine exofacial flopping, generates a biophysical microenvironment required for the docking of apoA-I at the cell surface.

Abstract
ATP-binding-cassette transporter 1 (ABC1) has been implicated in processes related to membrane-lipid turnover. Here, using in vivo loss-of-function and in vitro gain-of-function models, we show that ABC1 promotes Ca2+-induced exposure of phosphatidylserine at the membrane, as determined by a prothrombinase assay, membrane microvesiculation and measurement of transbilayer redistribution of spin-labelled phospholipids. That ABC1 promotes engulfment of dead cells is shown by the impaired ability of ABC1-deficient macrophages to engulf apoptotic preys and by the acquisition of phagocytic behaviour by ABC1 transfectants. Release of membrane phospholipids and cholesterol to apo-AI, the protein core of the cholesterol-shuttling high-density lipoprotein (HDL) particle, is also ABC1-dependent. We propose that both the efficiency of apoptotic-cell engulfment and the efflux of cellular lipids depend on ABC1-induced perturbation of membrane phosphatidylserine turnover. Transient local exposure of anionic phospholipids in the outer membrane leaflet may be sufficient to alter the general properties of the membrane and thus influence discrete physiological functions.

Abstract
The production of interleukin-1beta (IL-1beta), a powerful mediator of inflammation, is tightly regulated at several levels. However, in some pathologic conditions, a pharmacologic treatment is required to control the toxicity of excessive extracellular IL-1beta. Because of the heavy side effects of most therapies used in IL-1beta-mediated pathologies, a goal of pharmacologic research is the development of selective anti-IL-1beta drugs. We show here that the sulfonylurea glyburide, currently used in the oral therapy of noninsulin dependent diabetes, is an inhibitor of IL-1beta secretion from human monocytes and mouse macrophages. Glyburide reduces dramatically the recovery of extracellular 17-kD IL-1beta in the absence of toxic effects on the cells and without affecting the synthesis or processing of the IL-1beta precursor. IL-1beta belongs to the family of leaderless secretory proteins released from the cell by a nonclassical secretory route. In bacteria and yeast Atp binding cassette (ABC) transporters are involved in the secretion of leaderless secretory proteins. Interestingly, glyburide blocks the anion exchanger function of ABC1, a mammalian member of the family of ABC transporters. We thus investigated the involvement of ABC1 in IL-1beta secretion, through the analysis of the effects of drugs known to inhibit IL-1beta secretion, on the activity of ABC1 and in turn the ability of known inhibitors of ABC1 of blocking IL-1beta secretion. Our data show that IL-1beta secretion and the function of ABC1 as an anion exchanger are sensitive to the same drugs, therefore suggesting an involvement of the ABC1 transporter in the secretion of leaderless proteins in mammals.

Abstract
The ATP binding cassette transporter ABC1 is a 220-kDa glycoprotein expressed by macrophages and required for engulfment of cells undergoing programmed cell death. Since members of this family of proteins such as P-glycoprotein and cystic fibrosis transmembrane conductance regulator share the ability to transport anions, we have investigated the transport capability of ABC1 expressed in Xenopus oocytes using iodide efflux and voltage-clamp techniques. We report here that ABC1 generates an anion flux sensitive to glibenclamide, sulfobromophthalein, and blockers of anion transporters. The anion flux generated by ABC1 is up-regulated by orthovanadate, cAMP, protein kinase A, and okadaic acid. In other ABC transporters, mutating the conserved lysine in the nucleotide binding folds was found to severely reduce or abolish hydrolysis of ATP, which in turn altered the activity of the transporter. In ABC1, replacement of the conserved lysine 1892 in the Walker A motif of the second nucleotide binding fold increased the basal ionic flux, did not alter the pharmacological inhibitory profile, but abolished the response to orthovanadate and cAMP agonists. Therefore, we conclude that ABC1 is a cAMP-dependent and sulfonylurea-sensitive anion transporter.
