Activation of 5-HT Receptors in the Ventrolateral Orbital Cortex Produces Anti-Anxiodepressive Effects in a Rat Model of Neuropathic Pain.

The comorbidity of anxiety and depression frequently occurs in patients with neuropathic pain. The ventrolateral orbital cortex (VLO) plays a critical role in mediating neuropathic pain and anxiodepression in rodents. Previous studies suggested that 5-HT receptors in the VLO are involved in neuropathic pain.

Activation of 5-HT receptor in the ventrolateral orbital cortex produces antinociceptive effects in rat models of neuropathic and inflammatory pain.

The ventrolateral orbital cortex (VLO) is identified as an integral component of the endogenous analgesic system comprising a spinal cord - thalamic nucleus submedius - VLO - periaqueductal gray (PAG) - spinal cord loop. The present study investigates the effects of 5-HT receptor activation in the VLO on allodynia induced by spared nerve injury and formalin-evoked flinching behavior and spinal c-Fos expression in male SD rats, and further examines whether GABAergic modulation is involved in the effects evoked by VLO 5-HT receptor activation. We found an upregulation of 5-HT receptor expression in the VLO during neuropathic and inflammatory pain states.

CD147-specific chimeric antigen receptor T cells effectively inhibit T cell acute lymphoblastic leukemia.

T cell acute lymphoblastic leukemia (T-ALL) is invasive and heterogeneous, and existing therapies are sometimes unsuccessful. Chimeric antigen receptor (CAR) T cell therapy is a breakthrough tumor treatment method, particularly for B cell acute lymphoblastic leukemia. We found that CD147 was highly expressed in tumor T cells of T-ALL patients and T cell lymphoma.

Spinal 5-HT receptor is involved in electroacupuncture inhibition of chronic pain.

Knee osteoarthritis (KOA) is a highly prevalent, chronic joint disorder, and it is a typical disease which can develop chronic pain. Our previous study has proved that endocannabinoid (2-AG)-CB1R-GABA-5-HT pathway is involved in electroacupuncture (EA) mediated inhibition of chronic pain. However, it is still unclear which among the 5-HT receptor subtype is involved in EA evoked 5-HT mediated inhibition of chronic pain in the dorsal spinal cord.

Active demethylation upregulates CD147 expression promoting non-small cell lung cancer invasion and metastasis.

Non-small cell lung cancer (NSCLC) is a fatal disease, and its metastatic process is poorly understood. Although aberrant methylation is involved in tumor progression, the mechanisms underlying dynamic DNA methylation remain to be elucidated. It is significant to study the molecular mechanism of NSCLC metastasis and identify new biomarkers for NSCLC early diagnosis.

Ionizing Radiation-Induced RPL23a Reduction Regulates Apoptosis RPL11-MDM2-p53 Pathway in Mouse Spermatogonia.

Objective: The expression patterns of ribosomal large subunit protein 23a (RPL23a) in mouse testes and GC-1 cells were analyzed to investigate the potential relationship between RPL23a expression and spermatogonia apoptosis upon exposure to X-ray.

Methods: Male mice and GC-1 cells were irradiated with X-ray, terminal dUTP nick end-labelling (TUNEL) was performed to detect apoptotic spermatogonia . Apoptotic rate and cell cycle phase of GC-1 cells were analyzed with flow cytometry.

5-HT Receptor Is Involved in Electroacupuncture Inhibition of Chronic Pain in the Spinal Cord.

Knee osteoarthritis (KOA) is a common and disabling condition characterized by attacks of pain around the joints, and it is a typical disease that develops chronic pain. Previous studies have proved that 5-HT, 5-HT, and 5-HT receptors in the spinal cord are involved in electroacupuncture (EA) analgesia. The 5-HT receptor plays antinociceptive role in the spinal cord.
