In Drosophila melanogaster, 13 TRP channels have been identified, while Aedes aegypti and Anopheles gambiae possess 11 and 10, respectively, showcasing evolutionary adaptations to their ecological niches. This review explores recent advancements in understanding the structure, classification, and physiological functions of TRP channels, emphasizing their evolutionary divergence across Diptera, Lepidoptera, and Hymenoptera. Key TRP subfamilies, such as TRPA, TRPC, TRPM, TRPV, TRPN, and TRPP, are discussed, highlighting their roles in chemo-sensation, gustation, and stress responses. Examples include TRPA1's involvement in thermal sensing and TRPV's role in osmoregulation, critical for insect survival under fluctuating environmental conditions. The review highlights the potential of TRP channels as targets for pest control, focusing on TRP-specific insecticides like pymetrozine, afidopyrifen, and flonicamid, which impact feeding and sensory pathways. RNA interference (RNAi) techniques targeting TRP genes are highlighted as promising tools for innovative pest management. TRP channels' role in mediating thermal tolerance is particularly significant in the context of climate change, where variable temperatures challenge pest dynamics and agricultural sustainability. Understanding these mechanisms is vital for developing climate-resilient pest control strategies. The review also evaluates methodologies used in TRP channel studies, including genomic, transcriptomic, and functional assays, alongside behavioural analyses. Despite progress, challenges remain in studying TRP channels in non-model insects and elucidating their regulation. Future research should integrate multidisciplinary approaches to fully harness TRP channels for sustainable pest management.</p>","PeriodicalId":8329,"journal":{"name":"Archives of Toxicology","volume":" ","pages":""},"PeriodicalIF":4.8,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143582166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their unique structural properties and mechanisms of toxicity raise concerns regarding their potential misuse. Unlike classical organophosphorus compounds that inhibit acetylcholinesterase, BOPCs exert toxicity by antagonising gamma-aminobutyric acid receptors, resulting in severe neurotoxic effects, including convulsions and seizures. This underscores the urgent need to prioritise predictive toxicity studies on these compounds as part of a national defence strategy. The present study represents the first extensive application of in silico toxicological approaches to investigate the acute toxicity of a BOPC dataset (n = 18) utilising advanced in silico tools, such as QSAR models and probabilistic software/platforms, to predict acute oral toxicity in rats. All the investigated BOPCs are highly acutely toxic, judging from LD₅₀ values ranging for humans between < 1 mg and > 1.000 mg/kg bw, depending on the applied model. Noticeable variation between model predictions reminds us that present in silico approaches have significant limitations, at least when addressing chemically complex compounds, such as the BOPC class. This calls for wet-laboratory experimentation. Major toxicophoric groups, such as phosphate and phosphorothione moieties, have been identified as significant contributors to their toxicity. This study considers the need for high-level computational tools, well-founded experimental validation, targeted antidotes, and regulatory measures to reduce the risks from BOPCs and improve public health protection and chemical safety.</p>","PeriodicalId":8329,"journal":{"name":"Archives of Toxicology","volume":" ","pages":""},"PeriodicalIF":4.8,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143571593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While OTA is well-known for its nephrotoxic effects, emerging evidence highlights its neurotoxic potential. Parkinson's disease (PD) is a neurodegenerative disorder with both genetic and environmental aetiologies. Emerging lines of investigation have focused their research on the role of environmental toxins, including mycotoxins, in PD pathogenesis. However, the specific involvement of OTA in PD-related pathways still needs to be unravelled. This systematic review compiles and evaluates OTA neurotoxicity studies according to the adverse outcome pathway (AOP) for PD, established by the Organisation for Economic Cooperation and Development (OECD). The AOP framework outlines a series of key event (KEs) beginning with mitochondrial Complex I (CI) inhibition and progressing through mitochondrial dysfunction, impaired proteostasis, dopaminergic neuron degeneration, neuroinflammation, and resulting in parkinsonian motor deficits. In this systematic review, a comprehensive literature search was conducted in PubMed, to identify studies evaluating OTA neurotoxic effects. Using a search strategy of 19 terms and following a two-phased study selection, 30 relevant studies were retrieved, of which 16 dealt with in vitro adult neurotoxicity (ANT), 13 focused on in vivo ANT, and 1 gave both in vitro and in vivo approaches. Authors agree that in vitro and in vivo exposure to OTA causes mitochondrial dysfunction, impaired proteostasis, degeneration of dopaminergic (DA) neurons, and neuroinflammation. However, a notable absence of research remains on the molecular initiating event (MIE), binding to CI, and on KE1, inhibition of CI. This review identifies critical research gaps and highlights the need for further mechanistic studies on the impact of OTA on neurodegenerative pathways, particularly its binding and inhibition of CI, as well as mechanisms related to KE3: impaired proteostasis. Addressing these gaps may provide valuable insights into OTA neurotoxic potential and its relevance in PD-like neurodegeneration.</p>","PeriodicalId":8329,"journal":{"name":"Archives of Toxicology","volume":" ","pages":""},"PeriodicalIF":4.8,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143565877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One key concern is the reduction of antibody production, as seen with per- and poly-fluoroalkyl substances (PFASs), commonly known as \"forever chemicals.\" Both in vivo and epidemiological data show that PFASs have immunosuppressive effects, leading to reduced antibody responses, particularly following vaccination. In animal studies, the T cell-dependent (TD) antibody response is the gold standard for assessing chemical effects on immune function. This study utilized two in vitro approaches to investigate the effects of chemicals on antibody production using human peripheral blood mononuclear cells. Initial tests used unstimulated, negative (vehicle), and positive (rapamycin) controls to confirm the robustness of the models. Subsequently, four long-chain PFASs (PFOA, PFOS, PFNA, and PFHxS) were tested. Keyhole limpet hemocyanin (KLH) was used to mimic the TD response, while a TLR9 agonist and IL-2 activated B cells for T cell-independent (TI) immunoglobulin production. The results demonstrated the ability to reproduce TD and TI responses in vitro with robust, reproducible outcomes across a cohort of 20 human donors. The data, consistent with existing literature, showed a significant reduction in anti-KLH IgM production, especially for PFOA in male donors. Similar trends were observed for all PFASs in suppressing total TI IgG and IgM production. These methods closely replicated in vivo conditions, offering a potential alternative to animal models in immunotoxicity assessments.</p>","PeriodicalId":8329,"journal":{"name":"Archives of Toxicology","volume":" ","pages":""},"PeriodicalIF":4.8,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143565874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mechanisms underlying the beneficial effects of bisphosphonates on bone graft integration have been previously investigated. Previous studies have demonstrated that both local and systemic applications of bisphosphonates in the integration of autogenous and allogenic bone grafts yield promising results in enhancing allograft and autograft outcomes. Several animal studies have revealed that low to moderate doses of local bisphosphonate optimize new bone formation with good mechanical properties. In addition, bisphosphonates in combination with certain growth factors, such as bone morphogenetic protein (BMP)-7, have synergistic effects on the integration of both autogenous and allogenic bone grafts. However, only some clinical parameters support these findings from in vivo studies, including increased bone volume and density in bone-grafted areas following the integration of bone grafts. Thus, the present review aims to summarize and discuss the effects of bisphosphonates and the mechanistic insights associated with the integration of autogenous and allogenic bone grafts. The contradictory findings between studies will also be presented and discussed in this review. While the promising benefits of bisphosphonates on bone grafts have been reported, further research is still needed to investigate optimal dosage.

Liver tumours induced by PB are dependent upon the activation of the constitutive androstane receptor (CAR). However, marked species differences in CAR activation by exogenous chemicals exist with some being much more potent activators of human CAR, e.g., 6-(4-chlorophenyl)imidazo[2,1-β][1,3]thiazole-5-carbaldehyde-O-(3,4-dichlorobenzyl)oxime (CITCO). We have compared CITCO-induced tumour formation in the livers of mice in which murine CAR has been replaced with its human counterpart. Our findings reveal that CITCO-dependent liver tumours are only formed in mice-expressing human CAR and not in wild-type animals. In addition, contrary to one of the proposed mechanisms of NGC carcinogenicity, we show that CITCO did not induce a hyperplastic response in the liver of the humanised mice.

The objective of this study was to assess the enduring cardiac molecular impacts of DOX in old CD-1 male mice, focusing on ubiquitinated proteins. At 19 months of age, DOX group received a cumulative dose of 9.0 mg/kg of DOX, while control animals got saline solution. Animals were sacrificed 2 months after the administration. DOX induced heart structural changes and increased proteolytic activity. Additionally, increased protein ubiquitination was observed in DOX group, despite the decreased content of the E3 ubiquitin-protein ligase Atrogin-1. A search of poly-ubiquitinated proteins, enriched by tandem ubiquitin-binding entities (TUBEs), showed increased poly-ubiquitination of proteins associated with sarcomere organization and mitochondrial metabolism processes by DOX. Increased mitochondrial density inferred by higher citrate synthase activity was found in DOX group. Moreover, decreased biogenesis and auto(mito)phagy occurred in DOX animals, proven by decreased peroxisome proliferator-activated receptor γ coactivator 1 α, Beclin1 and microtubule-associated protein light chain 3 content. These findings indicate a reduction in mitochondrial biogenesis and accumulation of dysfunctional mitochondria in the aged heart, along with elevated levels of poly-ubiquitinated proteins after DOX treatment. Thus, the disruption of mitochondrial remodeling and impaired protein ubiquitination emerge as enduring consequences of DOX-induced cardiotoxicity, persisting for even 2 months after DOX exposure.
