: Post-treatment side effects of chemotherapy can include cognitive deficits commonly known as Chemo-brain. The treatment of patients with Doxorubicin (DOX), one of the most widely used chemotherapeutic drugs in the treatment of cancer, can induce depression, anxiety, and impaired cognitive function. Cannabidiol (CBD) is a non-psychoactive component of that has been identified as a possible therapeutic agent against many neurodegenerative disorders, including traumatic brain injury, spinal cord injury, Tau-protein-induced neurodegeneration, and neuropathic pain. Therefore, this study aimed to assess whether oral CBD administration could reduce DOX-induced anxiety and depression-like behaviors and alter the expression of mRNA associated with neuroinflammation. : Female Long Evans Hooded rats received intraperitoneal injections of DOX (6 mg/kg) or the vehicle (0.9% saline) once a week for four weeks, followed by oral administration of CBD (10 mg/kg) three times a week for the same period. : CBD was significantly protective against DOX-induced anxiety and depression-like behaviors, as measured by several behavioral tests. Furthermore, CBD improved DOX-induced alterations in the gene expression of biomarkers of neuroinflammation in the hippocampus and prefrontal cortex. : This provides insights into future studies on possible mechanisms by which DOX-induced cognitive dysfunction could be alleviated by CBD.
化疗的治疗后副作用可能包括通常被称为“化疗脑”的认知缺陷。阿霉素(DOX)是治疗癌症最广泛使用的化疗药物之一,对其患者的治疗可能会导致抑郁、焦虑和认知功能受损。大麻二酚(CBD)是大麻的一种非精神活性成分,已被确定为一种可能针对多种神经退行性疾病的治疗剂,包括创伤性脑损伤、脊髓损伤、 Tau蛋白诱导的神经退行性变和神经性疼痛。因此,本研究旨在评估口服CBD是否可以减轻DOX诱导的焦虑和抑郁样行为,并改变与神经炎症相关的mRNA表达。:雌性长Evans有帽大鼠每周一次腹腔注射DOX(6mg/kg)或赋形剂(0.9%生理盐水),持续四周,随后在同一时期每周口服三次CBD(10mg/kg)。:通过多项行为测试测量,CBD对DOX诱导的焦虑和抑郁样行为具有显著的保护作用。此外,CBD改善了DOX诱导的海马体和前额叶皮质神经炎症生物标志物基因表达的改变。:这为未来关于CBD缓解DOX诱导的认知功能障碍可能机制的研究提供了见解。
