Redox Biol 2024; 70:103072. [PMID: 38330550 PMCID: PMC10865407 DOI: 10.1016/j.redox.2024.103072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2024] [Revised: 01/27/2024] [Accepted: 01/31/2024] [Indexed: 02/10/2024] Open
Abstract
T-cell immunoglobulin domain and mucin domain-3 (Tim-3) is a versatile immunomodulator that protects against intestinal inflammation. Necroptosis is a type of cell death that regulates intestinal homeostasis and inflammation. The mechanism(s) underlying the protective role of macrophage Tim-3 in intestinal inflammation is unclear; thus, we investigated whether specific Tim-3 knockdown in macrophages drives intestinal inflammation via necroptosis. Tim-3 protein and mRNA expression were assessed via double immunofluorescence staining and single-cell RNA sequencing (sc-RNA seq), respectively, in the colonic tissues of patients with inflammatory bowel disease (IBD) and healthy controls. Macrophage-specific Tim3-knockout (Tim-3M-KO) mice were generated to explore the function and mechanism of Tim-3 in dextran sodium sulfate (DSS)-induced colitis. Necroptosis was blocked by pharmacological inhibitors of receptor-interacting protein kinase (RIP)1, RIP3, and reactive oxygen species (ROS). Additionally, in vitro experiments were performed to assess the mechanisms of neutrophil necroptosis induced by Tim-3 knockdown macrophages. Although Tim-3 is relatively inactive in macrophages during colon homeostasis, it is highly active during colitis. Compared to those in controls, Tim-3M-KO mice showed increased susceptibility to colitis, higher colitis scores, and increased pro-inflammatory mediator expression. Following the administration of RIP1/RIP3 or ROS inhibitors, a significant reduction in intestinal inflammation symptoms was observed in DSS-treated Tim-3M-KO mice. Further analysis indicated the TLR4/NF-κB pathway in Tim-3 knockdown macrophages mediates the TNF-α-induced necroptosis pathway in neutrophils. Macrophage Tim-3 regulates neutrophil necroptosis via intracellular ROS signaling. Tim-3 knockdown macrophages can recruit neutrophils and induce neutrophil necroptosis, thereby damaging the intestinal mucosal barrier and triggering a vicious cycle in the development of colitis. Our results demonstrate a protective role of macrophage Tim-3 in maintaining gut homeostasis by inhibiting neutrophil necroptosis and provide novel insights into the pathogenesis of IBD.

Xiang ZY, Tao DD. The role of calcium-sensitive receptor in ovalbumin-induced airway inflammation and hyperresponsiveness in juvenile mice with asthma. Kaohsiung J Med Sci 2022; 38:1203-1212. [PMID: 36169192 DOI: 10.1002/kjm2.12601] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 07/31/2022] [Accepted: 08/18/2022] [Indexed: 12/15/2022] Open
Abstract
The role of the calcium-sensitive receptor (CaSR) was assessed in a juvenile mouse model of asthma induced by ovalbumin (OVA). The experiment was divided into normal control, OVA, and OVA +2.5/5 mg/kg NPS2143 (a CaSR antagonist) groups. OVA induction was performed in all groups except the normal control, followed by assessing airway hyperresponsiveness (AHR) and lung pathological changes. Serum OVA-specific IgE and IgG1 were detected with an enzyme-linked immunosorbent assay (ELISA), and inflammatory cells were counted in bronchoalveolar lavage fluid (BALF). Real-time quantitative polymerase chain reaction, ELISA, and western blotting were performed to detect gene and protein expression. NPS2143 improved the OVA-induced AHR in mice, and AHR was higher in the OVA +2.5 mg/kg NPS2143 group than in the OVA +5 mg/kg NPS2143 group. Furthermore, NPS2143 reduced the production of OVA-specific IgE and IgG1 in serum and the number of eosinophils and lymphocytes in BALF in OVA mice with reduced CaSR expression in lung tissues. Besides, OVA-induced mice exhibited peribronchial and perivascular inflammatory cell infiltration, which was accompanied by severe goblet cell hyperplasia/hyperplasia and airway mucus hypersecretion. Furthermore, these mice exhibited increased levels of Interleukin (IL)-5, IL-13, MCP-1, and eotaxin, which were alleviated by NPS2143. The 5 mg/kg NPS2143 showed more effective than the 2.5 mg/kg treatment. CaSR expression was elevated in the lung tissues of OVA-induced asthmatic juvenile mice, whereas the CaSR antagonist NPS2143 reduced AHR and attenuated the inflammatory response in OVA-induced juvenile mice, possibly exerting therapeutic effects on childhood asthma.

Abstract
The Calcium-Sensing Receptor (CaSR) is a member of the class C of G-proteins coupled receptors (GPCRs), it plays a pivotal role in calcium homeostasis by directly controlling calcium excretion in the kidneys and indirectly by regulating parathyroid hormone (PTH) release from the parathyroid glands. The CaSR is found to be ubiquitously expressed in the body, playing a plethora of additional functions spanning from fluid secretion, insulin release, neuronal development, vessel tone to cell proliferation and apoptosis, to name but a few. The present review aims to elucidate and clarify the emerging regulatory effects that the CaSR plays in inflammation in several tissues, where it mostly promotes pro-inflammatory responses, with the exception of the large intestine, where contradictory roles have been recently reported. The CaSR has been found to be expressed even in immune cells, where it stimulates immune response and chemokinesis. On the other hand, CaSR expression seems to be boosted under inflammatory stimulus, in particular, by pro-inflammatory cytokines. Because of this, the CaSR has been addressed as a key factor responsible for hypocalcemia and low levels of PTH that are commonly found in critically ill patients under sepsis or after burn injury. Moreover, the CaSR has been found to be implicated in autoimmune-hypoparathyroidism, recently found also in patients treated with immune-checkpoint inhibitors. Given the tight bound between the CaSR, calcium and vitamin D metabolism, we also speculate about their roles in the pathogenesis of severe acute respiratory syndrome coronavirus-19 (SARS-COVID-19) infection and their impact on patients' prognosis. We will further explore the therapeutic potential of pharmacological targeting of the CaSR for the treatment and management of aberrant inflammatory responses.

Abstract
A number of species of the genus Trichilia (Meliaceae) exhibit anti-inflammatory effects. However, the effect of Trichilia martiana C. DC. (TM) on lipopolysaccharide (LPS)-induced inflammation has not, to the best of our knowledge, yet been determined. Therefore, in the present study, the antiinflammatory effect of TM on LPS-stimulated RAW264.7 macrophages was evaluated. The ethanol extract of TM (TMEE) significantly inhibited LPS-induced nitric oxide (NO), prostaglandin 2 (PGE2), inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). TMEE also reduced the levels of inflammatory cytokines, including tumor necrosis factor-alpha (TNF-α), interleukin (IL)-1β and IL-6. The upregulation of mitogen-activated protein kinases (MAPKs) and NF-κB activation was revealed to be downregulated following TMEE pretreatment. Furthermore, TMEE was indicated to lead to the nucleus translocation of nuclear factor erythroid-derived 2-related factor 2 (Nrf2) and the expression of heme oxygenase-1 (HO-1). In H292 airway epithelial cells, the pretreatment of TMEE significantly downregulated the production of LPS-stimulated IL-1β, and TMEE was indicated to increase the expression of HO-1. In animal models exhibiting LPS-induced acute lung injury (ALI), treatment with TMEE reduced the levels of macrophages influx and TNF-α production in the bronchoalveolar lavage fluid (BALF) of ALI mice. Additionally, TMEE significantly downregulated the activation of ERK, JNK and IκB, and upregulated the expression of HO-1 in the lungs of ALI mice. In conclusion, the results of the current study demonstrated that TMEE could exert a regulatory role in the prevention or treatment of the endotoxin-mediated inflammatory response.

Characterization of Negative Allosteric Modulators of the Calcium-Sensing Receptor for Repurposing as a Treatment of Asthma. J Pharmacol Exp Ther 2020; 376:51-63. [PMID: 33115824 DOI: 10.1124/jpet.120.000281] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2020] [Accepted: 10/05/2020] [Indexed: 12/16/2022] Open
Abstract
Asthma is still an incurable disease, and there is a recognized need for novel small-molecule therapies for people with asthma, especially those poorly controlled by current treatments. We previously demonstrated that calcium-sensing receptor (CaSR) negative allosteric modulators (NAMs), calcilytics, uniquely suppress both airway hyperresponsiveness (AHR) and inflammation in human cells and murine asthma surrogates. Here we assess the feasibility of repurposing four CaSR NAMs, which were originally developed for oral therapy for osteoporosis and previously tested in the clinic as a novel, single, and comprehensive topical antiasthma therapy. We address the hypotheses, using murine asthma surrogates, that topically delivered CaSR NAMs 1) abolish AHR; 2) are unlikely to cause unwanted systemic effects; 3) are suitable for topical application; and 4) inhibit airway inflammation to the same degree as the current standard of care, inhaled corticosteroids, and, furthermore, inhibit airway remodeling. All four CaSR NAMs inhibited poly-L-arginine-induced AHR in naïve mice and suppressed both AHR and airway inflammation in a murine surrogate of acute asthma, confirming class specificity. Repeated exposure to inhaled CaSR NAMs did not alter blood pressure, heart rate, or serum calcium concentrations. Optimal candidates for repurposing were identified based on anti-AHR/inflammatory activities, pharmacokinetics/pharmacodynamics, formulation, and micronization studies. Whereas both inhaled CaSR NAMs and inhaled corticosteroids reduced airways inflammation, only the former prevented goblet cell hyperplasia in a chronic asthma model. We conclude that inhaled CaSR NAMs are likely a single, safe, and effective topical therapy for human asthma, abolishing AHR, suppressing airways inflammation, and abrogating some features of airway remodeling. SIGNIFICANCE STATEMENT: Calcium-sensing receptor (CaSR) negative allosteric modulators (NAMs) reduce airway smooth muscle hyperresponsiveness, reverse airway inflammation as efficiently as topical corticosteroids, and suppress airway remodeling in asthma surrogates. CaSR NAMs, which were initially developed for oral therapy of osteoporosis proved inefficacious for this indication despite being safe and well tolerated. Here we show that structurally unrelated CaSR NAMs are suitable for inhaled delivery and represent a one-stop, steroid-free approach to asthma control and prophylaxis.

Int Immunopharmacol 2020; 85:106656. [PMID: 32504994 DOI: 10.1016/j.intimp.2020.106656] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2020] [Revised: 05/12/2020] [Accepted: 05/29/2020] [Indexed: 01/23/2023]
Abstract
3,4,5-Trihydroxycinnamic acid (THCA), a derivative of hydroxycinnamic acid, has been reported to exert anti-inflammatory and antioxidant activities. However, its anti-inflammatory effects in chronic obstructive pulmonary disease (COPD) have not yet been elucidated. Therefore, we explored the protective effects of THCA on pulmonary inflammation in an experimental COPD model elicited by cigarette smoke (CS) and lipopolysaccharide (LPS). Oral administration of THCA significantly inhibited the activity of elastase, the release of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and monocyte chemoattractant protein-1 (MCP-1), myeloperoxidase (MPO) and the numbers of neutrophils and macrophages in the bronchoalveolar lavage fluid (BALF) of experimental COPD mice. THCA also exerted inhibitory effects on the recruitment of inflammatory cells, the levels of PAS positive cells and cAMP-response-element-binding protein (CREB) activation, and the expression of phosphodiesterase 4 (PDE4) in the lungs of experimental COPD mice. In addition, THCA exerted a regulatory effect on the activation of p38, ERK and nuclear factor-κB (NF-κB) in the lungs of experimental COPD mice. THCA also significantly upregulated the expression of NAD(P)H dehydrogenase (quinone 1) 1 (NQO1) and the activation of nuclear factor erythroid-derived 2-related factor 2 (Nrf2) in the lungs of mice. Furthermore, THC restored the reduction of NAD-dependent protein deacetylase sirtuin-1 (SIRT1) in the lungs of experimental COPD mice. In phorbol myristate acetate (PMA)-stimulated A549 or H292 airway epithelial cells, pretreatment of THCA dose-dependently inhibited the generation of IL-6. THCA also led to increased NQO1 expression in H292 cells. Collectively, these protective effects of antioxidant THCA were notably excellent and are thought to be associated with the downregulation of MAPK (partial)/NF-κB signaling and upregulation of NQO1 and SIRT1 expression.

Abstract
Understanding and targeting of GPCRs remain a critical aspect of airway pharmacology and therapeutics for diseases such as asthma or COPD. Most attention has been on the large Class A GPCRs towards improved bronchodilation and blunting of remodeling. Better known in the central or peripheral nervous system, there is increasing evidence that Class C GPCRs which include metabotropic glutamate and GABA receptors, the calcium sensing receptor, sweet/umami taste receptors and a number of orphan receptors, can contribute to airway structure and function. In this review, we will summarize current state of knowledge regarding the pharmacology of Class C GPCRs, their expression and potential functions in the airways, and the application of pharmacological agents targeting this group in the context of airway diseases.

[PMID: 31391530 DOI: 10.1038/s41417-019-0128-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2019] [Revised: 07/15/2019] [Accepted: 07/20/2019] [Indexed: 12/13/2022]
Abstract
NPS-2143 is a calcium-sensing receptor (CaSR) antagonist that has been demonstrated to possess anticancer activity. To date, the effects of NPS-2143 on gastric cancer (GC) cell growth, motility, and apoptosis have not been investigated. In the present study, we firstly investigated the expression of CaSR in GC tissues using immunohistochemistry and western blotting. Then Cell Counting Kit-8 and colony formation assays were conducted to explore the effect of the NPS-2143 on the proliferation of GC cell line AGS. Transwell invasion and migration assays were performed to test the effect of NPS-2143 on AGS cell motility. We determined the percentage of apoptotic cells by flow cytometry and explored the changes of apoptosis-related protein by western blotting. Furthermore, we constructed a CaSR knockdown AGS cell line to determine whether NPS-2143 acted via inhibition of CaSR. We found that the protein expression level of CaSR was higher in GC tissues compared with the paired adjacent normal tissues. In addition, NPS-2143 treatment caused an inhibitory effect on the proliferation, invasion, and migration of AGS cells and a promoting effect on AGS apoptosis. The expression of Bcl-2 was decreased while the levels of Bax and active caspase 3 were enhanced in AGS cells after NPS-2143 treatment. Mechanistically, NPS-2143 lead to a significant decrease in the expression of phosphorylated (p)-AKT, phosphorylated mechanistic target of rapamycin (p-mTOR), p70, and cyclin D1. Knockdown of CaSR also suppressed cell proliferation, invasion, and migration and promoted cell apoptosis. No significant difference was observed between CaSR-silenced AGS cells with and without NPS-2143 treatment. These results confirmed that NPS-2143 has an inhibitory influence on AGS cell growth via inhibiting CaSR, which then suppresses the PI3K/Akt signaling pathway.

Pistacia weinmannifolia ameliorates cigarette smoke and lipopolysaccharide‑induced pulmonary inflammation by inhibiting interleukin‑8 production and NF‑κB activation. Int J Mol Med 2019; 44:949-959.

Abstract
Pistacia weinmannifolia (PW) has been used in traditional Chinese medicine to treat headaches, dysentery, enteritis and influenza. However, PW has not been known for treating respiratory inflammatory diseases, including chronic obstructive pulmonary disease (COPD). The present in vitro analysis confirmed that PW root extract (PWRE) exerts anti-inflammatory effects in phorbol myristate acetate- or tumor necrosis factor α (TNF-α)-stimulated human lung epithelial NCI-H292 cells by attenuating the expression of interleukin (IL)-8, IL-6 and Mucin A5 (MUC5AC), which are closely associated with the pulmonary inflammatory response in the pathogenesis of COPD. Thus, the aim of the present study was to evaluate the protective effect of PWRE on pulmonary inflammation induced by cigarette smoke (CS) and lipopoly-saccharide (LPS). Treatment with PWRE significantly reduced the quantity of neutrophils and the levels of inflammatory molecules and toxic molecules, including tumor TNF-α, IL-6, IL-8, monocyte chemoattractant protein-1, neutrophil elastase and reactive oxygen species, in the bronchoalveolar lavage fluid of mice with CS- and LPS-induced pulmonary inflammation. PWRE also attenuated the influx of inflammatory cells in the lung tissues. Furthermore, PWRE downregulated the activation of nuclear factor-κB and the expression of phosphodiesterase 4 in the lung tissues. Therefore, these findings suggest that PWRE may be a valuable adjuvant treatment for COPD.

Antagonism of Ca 2+-sensing receptors by NPS 2143 is transiently masked by p38 activation in mouse brain bEND.3 endothelial cells. Naunyn Schmiedebergs Arch Pharmacol 2019; 392:823-832.

Abstract
Ca2+-sensing receptors (CaSR) are G protein-coupled receptors which are activated by a rise in extracellular Ca2+. CaSR activation has been known to inhibit parathyroid hormone release and stimulate calcitonin release from parathyroid glands and thyroid parafollicular C cells, respectively. The roles of CaSR in other cell types including endothelial cells (EC) are much less understood. In this work, we demonstrated protein and functional expression of CaSR in mouse cerebral EC (bEND.3). Unexpectedly, CaSR response (high Ca2+-elicited cytosolic [Ca2+] elevation) was unaffected by edelfosine or U73122 but strongly suppressed by SK&F 96365, ruthenium red, and 2-aminoethoxydiphenyl borate (2-APB), suggesting involvement of TRPV and TRPC channels but not Gq-phospholipase C. Acute application of NPS2143, a negative allosteric modulator of CaSR, suppressed CaSR response. However, a 40-min NPS2143 pre-treatment surprisingly enhanced CaSR response. After 4-24 h of application, this enhancement faded away and suppression of CaSR response was observed again. Similar results were obtained when La3+ and Sr2+ were used as CaSR agonists. The transient NPS 2143 enhancement effect was abolished by SB203580, a p38 inhibitor. Consistently, NPS 2143 triggered a transient p38 activation. Taken together, results suggest that in bEND.3 cells, NPS 2143 caused acute suppression of CaSR response, but then elicited a transient enhancement of CaSR response in a p38-dependent manner. NPS 2143 effects on CaSR in bEND.3 cells therefore depended on drug exposure time. These findings warrant cautious use of this agent as a CaSR modulator and potential cardiovascular drug.

Abstract
Airway smooth muscle (ASM) regulation of airway structure and contractility is critical in fetal/neonatal physiology in health and disease. Fetal lungs experience higher Ca2+ environment that may impact extracellular Ca2+ ([Ca2+ ]o ) sensing receptor (CaSR). Well-known in the parathyroid gland, CaSR is also expressed in late embryonic lung mesenchyme. Using cells from 18-22 week human fetal lungs, we tested the hypothesis that CaSR regulates intracellular Ca2+ ([Ca2+ ]i ) in fetal ASM (fASM). Compared with adult ASM, CaSR expression was higher in fASM, while fluorescence Ca2+ imaging showed that [Ca2+ ]i was more sensitive to altered [Ca2+ ]o . The fASM [Ca2+ ]i responses to histamine were also more sensitive to [Ca2+ ]o (0-2 mM) compared with an adult, enhanced by calcimimetic R568 but blunted by calcilytic NPS2143. [Ca2+ ]i was enhanced by endogenous CaSR agonist spermine (again higher sensitivity compared with adult). Inhibition of phospholipase C (U73122; siRNA) or inositol 1,4,5-triphosphate receptor (Xestospongin C) blunted [Ca2+ ]o sensitivity and R568 effects. NPS2143 potentiated U73122 effects. Store-operated Ca2+ entry was potentiated by R568. Traction force microscopy showed responsiveness of fASM cellular contractility to [Ca2+ ]o and NPS2143. Separately, fASM proliferation showed sensitivity to [Ca2+ ]o and NPS2143. These results demonstrate functional CaSR in developing ASM that modulates airway contractility and proliferation.

Abstract
The extracellular calcium-sensing receptor (CaSR) is best known for its action in the parathyroid gland and kidneys where it controls body calcium homeostasis. However, the CaSR has different roles in the gastrointestinal tract, where it is ubiquitously expressed. In the colon, the CaSR is involved in controlling multiple mechanisms, including fluid transport, inflammation, cell proliferation and differentiation. Although the expression pattern and functions of the CaSR in the colonic microenvironment are far from being completely understood, evidence has been accumulating that the CaSR might play a protective role against both colonic inflammation and colorectal cancer. For example, CaSR agonists such as dipeptides have been suggested to reduce colonic inflammation, while dietary calcium was shown to reduce the risk of colorectal cancer. CaSR expression is lost in colonic malignancies, indicating that the CaSR is a biomarker for colonic cancer progression. This dual anti-inflammatory and anti-tumourigenic role of the CaSR makes it especially interesting in colitis-associated colorectal cancer. In this review, we describe the clinical and experimental evidence for the role of the CaSR in colonic inflammation and colorectal cancer, the intracellular signalling pathways which are putatively involved in these actions, and the possibilities to exploit these actions of the CaSR for future therapies of colonic inflammation and cancer.

Abstract
Rhododendron album Blume (RA) has traditionally been used as an herbal medicine and is considered to have anti‑inflammatory properties. It is a well‑known medicine for treatment of allergic or atopic diseases. In the present study, the biological effects of an RA methanol extract (RAME) on inflammation were investigated in tumor necrosis factor‑α (TNF‑α)/interferon‑γ (IFN‑γ)‑stimulated human keratinocytes. The present study aimed to investigate the potential mechanisms by which RAME inhibited TNF‑α/IFN‑γ‑induced expression of chemokines [thymus‑ and activation-regulated chemokine (TARC) and macrophage‑derived chemokine (MDC)] and cytokines [interleukin (IL)‑6 and IL‑8] through the nuclear factor‑κB (NF‑κB) pathway in human keratinocytes. The effects of RAME treatment on cell viability were investigated in TNF‑α/IFN‑γ‑stimulated HaCaT cells. The expression of TARC, MDC, IL‑6 and IL‑8 was assessed using reverse transcription‑quantitative polymerase chain reaction analysis or ELISA, and its effect on the inhibitory mitogen-activated protein kinase pathway was also studied using western blot analysis. TNF‑α/IFN‑γ induced the expression of IL‑6, IL‑8, TARC and MDC in a dose‑dependent manner through NF‑κB and Janus kinase/signal transducers and activators of transcription (JAK/STAT) activation. Notably, treatment with RAME significantly suppressed TNF-α/IFN-γ-induced expression of IL‑6, IL‑8, TARC, and MDC. In addition, RAME treatment inhibited the activation of NF‑κB and the JAK/STAT pathway in TNF‑α/IFN‑γ‑induced HaCaT cells. These results suggest that RAME decreases the production of chemokines and pro‑inflammatory cytokines by suppressing the NF‑κB and the JAK/STAT pathways. Consequently, RAME may potentially be used for treatment of atopic dermatitis.

Abstract
Pulmonary infection by Streptococcus pneumoniae is characterized by a robust alveolar infiltration of neutrophils (polymorphonuclear cells [PMNs]) that can promote systemic spread of the infection if not resolved. We previously showed that 12-lipoxygenase (12-LOX), which is required to generate the PMN chemoattractant hepoxilin A3 (HXA3) from arachidonic acid (AA), promotes acute pulmonary inflammation and systemic infection after lung challenge with S. pneumoniae As phospholipase A2 (PLA2) promotes the release of AA, we investigated the role of PLA2 in local and systemic disease during S. pneumoniae infection. The group IVA cytosolic isoform of PLA2 (cPLA2α) was activated upon S. pneumoniae infection of cultured lung epithelial cells and was critical for AA release from membrane phospholipids. Pharmacological inhibition of this enzyme blocked S. pneumoniae-induced PMN transepithelial migration in vitro Genetic ablation of the cPLA2 isoform cPLA2α dramatically reduced lung inflammation in mice upon high-dose pulmonary challenge with S. pneumoniae The cPLA2α-deficient mice also suffered no bacteremia and survived a pulmonary challenge that was lethal to wild-type mice. Our data suggest that cPLA2α plays a crucial role in eliciting pulmonary inflammation during pneumococcal infection and is required for lethal systemic infection following S. pneumoniae lung challenge.

Abstract
The calcium-sensing receptor (CaSR) plays a pivotal role in systemic calcium metabolism by regulating parathyroid hormone secretion and urinary calcium excretion. The diseases caused by an abnormality of the CaSR are genetically determined or are more rarely acquired. The genetic diseases consist of hyper- or hypocalcemia disorders. Hypercalcaemia disorders are related to inactivating mutations of the CASR gene either heterozygous (autosomal dominant familial benign hypercalcaemia, still named hypocalciuric hypercalcaemia syndrome type 1) or homozygous (severe neonatal hyperparathyroidism). The A986S, R990G and Q1011E variants of the CASR gene are associated with higher serum calcium levels than in the general population, hypercalciuria being also associated with the R990G variant. The differential diagnosis consists in the hypocalciuric hypercalcaemia syndrome, types 2 (involving GNA11 gene) and 3 (involving AP2S1 gene); hyperparathyroidism; abnormalities of vitamin D metabolism, involving CYP24A1 and SLC34A1 genes; and reduced GFR. Hypocalcemia disorders, which are more rare, are related to heterozygous activating mutations of the CASR gene (type 1), consisting of autosomal dominant hypocalcemia disorders, sometimes with a presentation of pseudo-Bartter’s syndrome. The differential diagnosis consists of the hypercalciuric hypocalcaemia syndrome type 2, involving GNA11 gene and other hypoparathyroidism aetiologies. The acquired diseases are related to the presence of anti-CaSR antibodies, which can cause hyper- or especially hypocalcemia disorders (for instance in APECED syndromes), determined by their functionality. Finally, the role of CaSR in digestive, respiratory, cardiovascular and neoplastic diseases is gradually coming to light, providing new therapeutic possibilities. Two types of CaSR modulators are known: CaSR agonists (or activators, still named calcimimetics) and calcilytic antagonists (or inhibitors of the CasR). CaSR agonists, such as cinacalcet, are indicated in secondary and primary hyperparathyroidism. Calcilytics have no efficacy in osteoporosis, but could be useful in the treatment of hypercalciuric hypocalcaemia syndromes.
