Abstract
Cow's milk allergy (CMA) is common in early childhood and the incidence is increasing. However, its mechanisms of action are still not fully understood due to the range of different clinical symptoms. So far, the development of different mouse models has been the best choice to study the molecular mechanisms triggering allergy. However, the selection of suitable strains for the establishment of animal models truly representative of associated human pathologies is still a challenge. Hence, we focused on both C3H/HeNCrl and BALB/c mice to characterize their susceptibility to CMA. After intraperitoneal sensitization, BALB/c and C3H/HeNCrl strains were challenged with β-lactoglobulin (BLG), and compared in allergic symptoms and active immune response, which assessed by specific antibody production and cytokine release. At first, both groups exhibited anaphylaxis, showed specific BLG-related IgE, Th2 response and seemed both suitable for the development of CMA models. However, a detailed analysis revealed that BALB/c had both stronger humoral and Th2 immune responses, producing more antibodies (IgE and IgG/IgG1/IgG2a), and releasing higher levels of Th2-associated cytokines (IL-4, IL-5, IL-13) compared to C3H/HeNCrl mice. Therefore, BALB/c strain would represent a preferential choice in the establishment of CMA models. This study highlights the subtle differences and major outcomes in the selection of mouse strains for the development of suitable food allergy models.

[PMID: 38584553 DOI: 10.2174/0113816128288970240321073436] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Revised: 02/29/2024] [Accepted: 03/04/2024] [Indexed: 04/09/2024]
Abstract
BACKGROUND Targeting immunogenic cell death (ICD) is considered a promising therapeutic strategy for cancer. However, the commonly identified ICD inducers promote the expression of programmed cell death ligand 1 (PD-L1) in tumor cells, thus aiding them to evade the recognition and killing by the immune system. Therefore, the finding of novel ICD inducers to avoid enhanced PD-L1 expression is of vital significance for cancer therapy. Celastrol (CeT), a triterpene isolated from Tripterygium wilfordii Hook. F induces various forms of cell death to exert anti-cancer effects, which may make celastrol an attractive candidate as an inducer of ICD. METHODS In the present study, bioinformatics analysis was combined with experimental validation to explore the underlying mechanism by which CeT induces ICD and regulates PD-L1 expression in clear cell renal cell carcinoma (ccRCC). RESULTS The results showed that EGFR, IKBKB, PRKCQ and MAPK1 were the crucial targets for CeT-induced ICD, and only MAPK1 was an independent prognostic factor for the overall survival (OS) of ccRCC patients. In addition, CeT triggered autophagy and up-regulated the expressions of HMGB1 and CRT to induce ICD in 786-O cells in vitro. Importantly, CeT can down-regulate PD-L1 expression through activating autophagy. At the molecular level, CeT suppressed PD-L1 via the inhibition of MAPK1 expression. Immunologically, the core target of celastrol, MAPK1, was tightly correlated with CD8+ T cells and CD4+ T cells in ccRCC. CONCLUSION These findings indicate that CeT not only induces ICD but also suppresses PD-L1 by down-regulating MAPK1 expression, which will provide an attractive strategy for ccRCC immunotherapy.

Optimization of green extraction process with natural deep eutectic solvent and comparative in vivo pharmacokinetics of bioactive compounds from Astragalus-Safflower pair. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 114:154814. [PMID: 37062134 DOI: 10.1016/j.phymed.2023.154814] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Revised: 03/25/2023] [Accepted: 04/09/2023] [Indexed: 06/19/2023]
Abstract
INTRODUCTION Natural deep eutectic solvents (NaDESs) are promising not only in componential extraction, but also in drug delivery system due to their green and safe features. In this work, NaDESs were applied to extract bioactive components from Astragalus-Safflower pair, a classic traditional Chinese medicine combination. Furthermore, ready-to-use crude extracts were administrated to SD rats. METHODS Total 9 NaDESs composed of food grade ingredients were screened for the extraction of representative 9 components (hydroxysafflor yellow A, anhydrosafflor yellow B, eleutheroside B, calycosin-7-O-glucoside, kaempferol-3-O-rutinoside, ononin, calycosin, astraganoside, and carthamin) from Astragalus-Safflower pair. Afterwards, genetic artificial neural network (GNN) was adopted for optimizing the ultrasound-assisted extraction process. After SD rats were orally administrated with the ready-to-use crude extracts extracted under the optimized conditions, the in vivo pharmacokinetic characteristics of 5 components were evaluated comprehensively from weight, gender, solvent and modeling surgery, under a well-established UPLC-MS/MS method. RESULTS Betaine-Lactic acid (Bet-Lac) was eventually determined as the optimal extraction solvent for subsequent experiments. The optimal ultrasound assisted extraction process was as follows: 90 min of extraction time, 65 °C of temperature, 80% of Bet-Lac content and 50 mg/ml of solid-liquid ratio. Bet-Lac enhanced to varying degrees the bioavailability of analytes in normal and cerebral ischemia/reperfusion injured (CI/RI) rats in contrast with corresponding rats administrated with water extract groups (p < 0.05). Besides, the bioavailability of active components in CI/RI rat plasma was significantly lower than that in normal rats (p < 0.05), indicating pathological damage of CI/R had a significant impact on pharmacokinetic profile of compounds in rats. However, gender and body weight had no significant effects on the pharmacokinetic profile of bioactive components. CONCLUSIONS NaDESs exhibited higher extraction efficiency than conventional solvents. And GNN is reliable to optimize the ultrasound assisted extraction process. This study supported the potential of non-toxic NaDESs as solvents for extraction process and drug delivery systems at the same time.
