Article Abstract

Background: Bisphenol A (BPA) is a known neurotoxic compound with potentially harmful effects on the nervous system. Cyanidin (CYN) has shown promise as a neuroprotective agent.

Objective: The current study aims to determine the efficacy of CYN against BPA-induced neuropathology.

Methods: experiments utilized PC12 cells were pre-treated with gradient doses of CYN and further stimulated with 10ng/ml of BPA. DPPH radical scavenging activity, catalase activity, total ROS activity, and nitric oxide radical scavenging activity were done. assessments employed doublecortin immunohistochemistry of the brain in BPA-exposed Sprague-Dawley rats. Further, molecular docking of CYN with all proteins involved in canonical Wnt signaling was performed using the Autodock v4.2 tool and BIOVIA Discovery Studio Visualizer.

Results: IC values of CYN and ascorbic acid were determined using dose-response curves, and it was found to be 24.68 ± 0.563 μg/ml and 20.69 ± 1.591μg/ml, respectively. BPA-stimulated cells pre-treated with CYN showed comparable catalase activity with cells pre-treated with ascorbic acid (p = 0.0287). The reactive species production by CYN-treated cells was significantly decreased compared to BPA-stimulated cells (p <0.0001). Moreover, CYN significantly inhibited nitric oxide production compared to BPA stimulated and the control cells (p < 0.0001). CYN positively affected immature neuron quantity, correlating with dosage. During molecular docking analysis, CYN exhibited a binding affinity > -7 Kcal/mol with all the key proteins associated with the Wnt/β- catenin signaling cascade.

Conclusion: Conclusively, our finding suggests that CYN exhibited promise in counteracting BPAinduced oxidative stress, improving compromised neurogenesis in hippocampal and cortical regions, and displaying notable interactions with Wnt signaling proteins. Thereby, CYN could render its neuroprotective potential against BPA-induced neuropathology.

Background: Aerobic vaginitis (AV) is a state of abnormal vaginal microbiota, which is associated with increased numbers of aerobic, enteric bacteria and inflammation of the vaginal epithelium. Anti-microbial treatment combined with anti-inflammatory therapy could be useful in the treatment of this condition. It is known that calcitriol, the active form of vitamin D, plays an important role in modulating the immune response in several inflammatory diseases.

Background: Diabetes mellitus (DM), a chronic metabolic disease, is characterized by long-term hyperglycemia resulting from the defect of insulin production and insulin resistance. The damage and dysfunction of pancreatic β-cells is a main link in DM development.

Methods: In this work, pancreatic β-cell line INS-1E cells were exposed to 30 mM glucose for 48 h to construct an in vitro DM model.

Nasopharyngeal carcinoma (NPC) is an Epstein-Barr virus (EBV)-associated cancer, and immune checkpoint inhibitors (ICIs) have shown efficacy in its treatment. The combination of chemotherapy and ICIs represents a new trend in the standard care for metastatic NPC. In this study, we aim to clarify the immune cell profile and related prognostic factors in the ICI-based treatment of metastatic NPC.

Hybrid lipid nanoparticles with tumor antigen-primed dendritic cell membranes for post-surgical tumor immunotherapy.

J Control Release

Post-surgical tumor recurrence poses a major challenge in cancer treatment due to residual tumor cells and surgery-induced immunosuppression. Here, we developed hybrid nanoparticles, termed T-DCNPs, designed to promote antigen-specific activation of cytotoxic CD8+ T cells while concurrently inhibiting immunosuppressive pathways within the tumor microenvironment. T-DCNPs were formulated by co-extruding lipid nanoparticles containing a transforming growth factor β inhibitor with dendritic cells that were pre-treated with autologous neoantigens derived from surgically excised tumors.

Objective: To investigate the reparative effect of hypoxia pretreated hAMSCs on radiation-induced damage to salivary gland function in mice.

Methods: hAMSCs were separated from human amniotic tissues by mechanical and enzymatic digestion methods and a 15 Gy electron beam was used to locally irradiate the neck of mouse to create a salivary gland injury model. The mouse models were randomly divided into four groups: control group, IR+PBS group, IR+Nor group and IR+HP group.
