[PMID: 35202265 PMCID: PMC8875078 DOI: 10.3390/toxics10020079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Revised: 01/31/2022] [Accepted: 02/02/2022] [Indexed: 02/04/2023]
Abstract
Background: The treatment of relapsed or refractory leukemia remains a major problem. Among the new therapeutic approaches, the use of modified T lymphocytes, called chimeric antigen receptor T cells (CAR-T cells), seems promising. The first step of their preparation is leukapheresis, which involves the collection of mononuclear cells from the patient. This medical procedure requires numerous medical devices (MDs) made of plasticized polyvinylchloride (PVC). These compounds can leach out of the devices during contact with the patient’s blood. The aim of our study was to evaluate the migration of the plasticizers contained in the MD during a simulated pre-CAR-T cell leukapheresis procedure, and to measure the patient’s and their lymphocytes’ exposure to them. Methods: The qualitative and quantitative composition of the MD used for pre-CAR-T cell apheresis was determined by gas chromatography–mass spectrometry (GC–MS). Then, an ex vivo leukapheresis model using an ethanol/water simulant was performed to evaluate the plasticizers’ migration under simulated clinical conditions of pre-CAR-T cells’ cytapheresis. The plasticizers released into the simulant were quantified by GC–MS. Results: Diethylhexylphthalate (DEHP) was found in the apheresis kit, with amounts ranging from 25% to 59% (g/100 g of PVC). Bis(2-ethylhexyl) adipate was detected at trace levels. A total of 98.90 ± 11.42 mg of DEHP was released into the simulant, corresponding to an exposure dose of 1.4 mg/kg for a 70 kg patient. Conclusions: Patients undergoing a pre-CAR-T cell apheresis are mainly exposed to DEHP, which can impact their health because of its endocrine disruption effect, but could also lead to a decrease in CAR-T cells’ efficiency/quality.

Abstract
Phthalates are among the most ubiquitous environmental contaminants and endocrine-disrupting chemicals. Exposure to phthalates and related health effects have been extensively studied over the past four decades. An association between phthalate exposure and allergic diseases has been suggested, although the literature is far from conclusive. This article reviews and evaluates epidemiological (n = 43), animal (n = 49), and cell culture studies (n = 42), published until the end of 2019, on phthalates and allergic diseases, such as asthma, rhinoconjunctivitis, and eczema. In contrast to earlier reviews, emphasis is placed on experimental studies that use concentrations with relevance for human exposure. Epidemiological studies provide support for associations between phthalate exposures and airway, nasal, ocular, and dermal allergic disease outcomes, although the reported significant associations tend to be weak and demonstrate inconsistencies for any given phthalate. Rodent studies support that phthalates may act as adjuvants at levels likely to be relevant for environmental exposures, inducing respiratory and inflammatory effects in the presence of an allergen. Cell culture studies demonstrate that phthalates may alter the functionality of innate and adaptive immune cells. However, due to limitations of the applied exposure methods and models in experimental studies, including the diversity of phthalates, exposure routes, and allergic diseases considered, the support provided to the epidemiological findings is fragmented. Nevertheless, the current evidence points in the direction of concern. Further research is warranted to identify the most critical windows of exposure, the importance of exposure pathways, interactions with social factors, and the effects of co-exposure to phthalates and other environmental contaminants.

Abstract
Asthma is a chronic inflammatory disorder of the airway, characterized by airway hyperresponsiveness. It is a disabling disease with an increasing prevalence, resulting in heavy social and economic burdens worldwide. Humans are extensively exposed to phthalates, and many epidemiological studies have shown a relationship between phthalate exposure and asthma in recent decades. Earlier experimental studies focused on inflammatory cells, demonstrating the adjuvant effects, immunomodulatory effects, or immunosuppressive effects related to phthalate exposure. Recent studies have shown that phthalates may have a direct effect on airway epithelial cells and contribute to airway remodeling, which is the cardinal pathologic characteristic of chronic asthma, with a high correlation with disease severity. Through these efforts, phthalates have been recognized as important environmental factors in the pathogenesis of asthma, but further studies are still required to elucidate the detailed mechanism. This review discusses the current status of human exposure to phthalates in Taiwan and summarizes the epidemiological and experimental evidence related to the roles of phthalate exposure in the development of asthma and associated diseases.

Abstract
The aim of the present study was to evaluate the inhibitory effect of glycoprotein isolated from Cudrania tricuspidata Bureau (CTB glycoprotein) on di(2-ethylhexyl) phthalate (DEHP)-induced allergic inflammatory response in mice. We evaluated the activity of β-hexosaminidase, expression of cyclooxygenase (COX)-2, p38 mitogen-activated protein kinase (MAPK), and activator protein (AP)-1, and production of immunoglobulin (Ig)E and interleukin (IL)-4 in DEHP-treated RBL-2H3 cells and ICR mice. Our results revealed that the CTB glycoprotein inhibited the activity of β-hexosaminidase and production of IgE and IL-4 in serum from DEHP-treated mice. We also found that the CTB glycoprotein reduced arachidonic acid release, COX-2 expression, and AP-1 transcriptional activation through p38 MAPK phosphorylation in DEHP-treated RBL-2H3 cells. The activation of AP-1 was completely blocked by treatment with p38 MAPK inhibitor (SKF86002). The results from these experiments indicate that CTB glycoprotein effectively protects against the allergic inflammation response, mainly through downregulation of MAPK/AP-1 in the mast cell degranulation stage. In conclusion, we suggest that the CTB glycoprotein may be one component of health supplements for the prevention of allergic inflammation.

Abstract
Phthalate esters as plasticizers have been widespread in the environment and may be associated with development of allergic diseases such as asthma and atopic dermatitis. In this study, we demonstrated that the CTB glycoprotein attenuates allergic reactions caused by di(2-ethylhexyl) phthalate (DEHP) in human mast cells (HMC-1). This experiment evaluated degranulation of histamine and β-hexosaminidase as well as activities of protein kinase C (PKC), stress-activated protein kinase/c-Jun N-terminal kinase (SAPK/JNK), activator protein (AP)-1 and interleukin (IL)-4 and tumor necrosis factor (TNF)-α using immunoblotting and reverse transcription-polymerase chain reaction (RT-PCR). Our results revealed that the CTB glycoprotein in the presence of DEHP inhibits degranulation of mast cell, translocation of PKC from cytosol to membrane, and phosphorylation of SAPK/JNK in HMC -1 cells. We also found that the CTB glycoprotein (100 μg mL(-1) ) has suppressive effects on transcriptional activation of AP-1, and on the expression of IL-4 and TNF-α in DEHP-treated HMC-1 cells. We suggest that the CTB glycoprotein inhibits degranulation of mast cells and expressions of cytokines in HMC-1 cells.

We evaluated the activities of mitogen-activated protein kinase (MAPK), transcriptional factor, and production of immunoglobulin (Ig)E and interleukin (IL)-4 in RBL-2H3 cells and BALB/c mice. Our results showed that CTB glycoprotein inhibited the production of IgE and IL-4 in serum from ovalbumin (OVA)-treated BALB/c mice. We also found that CTB glycoprotein inhibited the phosphorylation of p38 MAPK, and transcriptional activation of nuclear factor (NF)-κB in RBL-2H3 cells. The activation of NF-κB was effectively blocked by treatment with p38 MAPK inhibitor (SKF86002). The results from these experiments indicate that the CTB glycoprotein inhibits release of β-hexosaminidase, and production of IgE and IL-4 via down regulation of MAPK/ NF-κB on the stage of mast cell degranulation. In conclusion, we suggest that the CTB glycoprotein might be a potent preventive agent in allergic responses.

Abstract
This study investigated the inhibitory effect of a glycoprotein isolated from Cudrania tricuspidata Bureau (CTB glycoprotein) on di(2-ethylhexyl) phthalate (DEHP)-induced mast cell degranulation and related signaling cascade in RBL-2H3 cells. This experiment evaluated the intracellular Ca(2+) level, and the activities of protein kinase C (PKC), mitogen-activated protein kinase (MAPK), transcription factor, and the cytokines in DEHP-treated RBL-2H3 cells. Our results revealed that the CTB glycoprotein in the presence of DEHP inhibits the release of histamine and expression of interleukin (IL)-4, IL-6, and TNF-alpha in RBL-2H3 cells. We also found that the CTB glycoprotein inhibits the intracellular Ca(2+) level, translocation of PKC from cytosol to membrane and the phosphorylation of ERK1/2 in cells. Moreover, the CTB glycoprotein (100 microg/ml) has suppressive effects on transcriptional activation of nuclear factor (NF)-kappaB in DEHP-treated RBL-2H3 cells. The activation of NF-kappaB was collectively blocked by treatment with PKC inhibitor (staurosporine) as well as ERK1/2 inhibitor (PD98059), respectively. The results from these experiments indicated that the CTB glycoprotein inhibits release of histamine and expressions of IL-4, IL-6, and TNF-alpha via down regulations of PKC/MAPK and NF-kappaB on the stage of mast cell degranulation induced by DEHP. Moreover, oral administration of CTB glycoprotein (10-20 mg/kg) inhibited compound 48/80-mediated systemic reaction in mice. In conclusion, we speculated that the CTB glycoprotein might be one component for preparation of health supplements for prevention of allergic immune disorders.

Abstract
During the last decades more than 100 000 new chemicals have been introduced to the environment. Many of these new chemicals and many common consumer products that include these have been shown to be toxic in animal studies and an increasing body of evidence suggests that they are also impacting human health. Among the suspect chemicals, the endocrine disrupting chemicals (EDCs) are of particular concern. One such chemical group is the phthalates, used in soft poly vinyl chloride (PVC) material and in a huge number of consumer products. During the same period of time that the prevalence of these modern chemicals has increased, there has been a remarkable increase in several chronic illnesses, including asthma and allergy in children. In this article we outline the scientific knowledge on phthalate exposure for asthma and airway diseases in children by examining epidemiological and experimental peer review data for potential explanatory mechanisms. Epidemiological data point to a possible correlation between phthalate exposure and asthma and airway diseases in children. Experimental studies present support for an adjuvant effect on basic mechanisms in allergic sensitization by several phthalates. Despite variations in the experimental design and reported result in the individual studies, a majority of published reports have identified adjuvant effects on Th2 differentiation, production of Th2 cytokines and enhanced levels of Th2 promoted immunoglobulins (mainly IgG1 but also IgE) in mice. A limited amount of data do also suggest phthalate-induced enhancement of mast cell degranulation and eosinophilic infiltration which are important parts in the early inflammation phase. Thus, some of the early key mechanisms in the pathology of allergic asthma could possibly be targeted by phthalate exposure. But the important questions of clinical relevance of real life exposure and identification of molecular targets that can explain interactions largely remain to be answered.
