We verify the structure using mutagenesis and confirm that the conformation corresponds to the active state of the receptor. Subsequent study of TrkB interaction with the antidepressant drug fluoxetine, and the antipsychotic drug chlorpromazine, provides a clear self-consistent model, describing the mechanism by which fluoxetine activates the receptor by binding to its transmembrane domain.

Depression degree in patients with malignant bone tumors correlates with serum inflammatory factors and thyroxine levels. Measurement of serum inflammatory factors and thyroxine levels can assess the progression and prognosis of depressed patients.

Additional candidates like pinocembrin, which reduces NSCLC cell invasion by modulating epithelial-mesenchymal transition, and citalopram, an SSRI with anti-carcinogenic properties, were also identified. These findings provide valuable insights into the molecular underpinnings of NSCLC and suggest new directions for therapeutic strategies through drug repurposing.

Collectively, our findings showed the diversity of tumor vascular endothelial cells across VEGF and non-VEGF pathways led to anti-angiogenic resistance. The combination of axitinib and sertraline can represent an effective anti-angiogenic therapy for glioblastoma with safe, low cost, and fast availability.

One hour before CUMS, rats were given a treatment with acupuncture, electroacupuncture, sham-acupuncture, or fluoxetine (2.1 mg/kg)...Additionally, our findings indicate that acupuncture also modulates the ERK and Caspase-3 apoptotic pathways in the hippocampus of CUMS rats. This study suggests that acupuncture may play a potential preventive role by regulating hippocampal neuroinflammatory response, levels of oxidative stress, apoptotic processes, and enhancing synaptic plasticity.

Fluoxetine and CUR-N373 can inhibit CVB4 replication in macrophage cultures...The cytolytic activity of activated GM-CSF macrophages was higher towards CVB4-persistently infected 1.1B4 cells than mock-infected 1.1B4 cells. In conclusion, macrophages may play a role in CVB4 infection of pancreatic cells, and are capable of inducing lysis of infected pancreatic cells.

Retrospective analysis reveals that SSRI use correlates with a lower risk of metastasis among patients with HCC. Our study describes a role for SSRIs in cancer metabolism, establishing a rationale for their repurposing as potential anti-cancer drugs for HCC.

The rats were randomly divided into normal group, model group, CD300f blocker(CLM1, 2 μg·kg~(-1)) group, CD300f agonist(Fcγ, 5 μg·kg~(-1)) group, positive drug(0.18 g·kg~(-1) metformin+1.8 mg·kg~(-1) fluoxetine) group, and high-dose and low-dose(20.52 and 10.26 g·kg~(-1)) Zuogui Jiangtang Jieyu Formula groups. They could up-regulate the protein expression of presyna-ptic membrane SYN and postsynaptic membrane PSD-95 in hippocampal neurons and finally improve the damage to the hippocampal synaptic microenvironment. In conclusion, this research confirmed that Zuogui Jiangtang Jieyu Formula effectively alleviated the depression-like behavior and inhibited inflammatory activation of microglial cells in the hippocampus of rats with DD, and the mechanism might be related to the regulation of CD300f/TLR4 signal to alleviate the damage to hippocampal synaptic microenvironment.

Results suggest that R- and S-ketamine have pro-neurogenic and anti-inflammatory properties, however, this is mediated by inhibition of the kynurenine pathway only in the context of IL-1b. Overall, this study enhances our understanding of the mechanisms underlying ketamine's antidepressant effects in the context of different inflammatory phenotypes, ultimately leading to the development of more effective, personalised therapeutic approaches for patients suffering from depression.

Age, antidepressant type, duration of antidepressant use, and comorbidities could be risk factors for NAFLD in patients with depression. Furthermore, mirtazapine can cause steatosis in both AML-12 and MIHA cell lines and may promote the development of NAFLD through the TLR4/MyD88/NF-κB signaling pathway. This study lays a solid foundation for further research on depression and NAFLD and can contribute to the prevention and treatment of these two diseases.

Sertraline remarkably augmented paclitaxel-induced autophagy by increasing autophagosome formation indicated by elevated LC3-II/I ratio and promoting autophagic flux by degrading autophagy cargo receptor SQSTM1/p62, which may explain the synergistically cytotoxic effect of sertraline and paclitaxel combination therapy on CRC cells. This study provides important evidence to support repurposing sertraline as an anticancer agent and suggests a novel combinational regimen for effectively treating CRC as well as in the simultaneous treatment of CRC and depression.

In the co-culture model, the immunological effects of escitalopram oxalate on MCF-7 cells were 2.8%, 11.1%, 15.6%, 10.6%, and 12.1% for interleukin (IL)-1β, IL-6, IL-8, IL-10, and TNF-α, respectively, while MDA effects on MB-231 cells, respectively, were 2.1%, 15.9%, 16.2%, 8.8%, and 11.8%. According to the results obtained, it was concluded that the immunological effects of escitalopram oxalate are more effective than tamoxifen and that it can be used as an adjunctive agent in breast cancer treatment.

From 15 th to the 22 nd day, the animals received RIP I or RIP II (50 mg/kg) or fluoxetine (FLU, 10 mg/kg) or vehicle, by gavage...RIP I and RIP II reversed these alterations. These results contribute to the understanding the mechanisms underlying the antidepressant effect of RIP I and RIP II, which may be related to neuroinflammatory suppression.
