Background: is a common opportunistic infection in patients with acquired immune deficiency syndrome (AIDS) in South China. Spinal cord abscesses caused by are exceptionally rare and present with non-specific symptoms, which may result in delayed diagnosis and heightened adverse prognoses.
Case Presentation: We report a case of a spinal cord abscess in a 30-year-old patient with AIDS that was caused by infection. The patient initially presented with septicemia and pleurisy. After initial antifungal treatment and combined antiretroviral therapy (cART), the patient's condition temporarily improved. However, he discontinued the antifungal treatment against medical advice and subsequently developed paraplegia, meningitis, and related intracranial and thoracic spinal cord lesions. Neurosurgical resection of the spinal cord lesion, combined with continued cART and antifungal treatment, resulted in the intracranial mass in the cerebellum resolving on MRI, but the patient remained non-ambulatory and incontinent during the last follow-up in August 2024.
Conclusion: In patients with spinal cord abscesses and a history of disseminated infection, especially those with AIDS, talaromycosis should be considered as a potential differential diagnosis. Comprehensive management, encompassing adherence to treatment plans and effective follow-up, is crucial for improving prognosis.

Background: Osteosarcoma, an aggressive bone malignancy predominantly affecting children and adolescents, presents significant therapeutic challenges with a 5-year survival rate below 30% in metastatic cases. T-cell exhaustion, characterized by the overexpression of immune checkpoint molecules, contributes to osteosarcoma progression and immune evasion. Although targeting these inhibitory pathways has shown potential in restoring T-cell activity, the molecular regulators of T-cell depletion in osteosarcoma are poorly understood.

Background: Varicella-zoster virus (VZV) central nervous system infection is typically observed in immunocompromised patients, and there is a lack of studies involving large samples of non-immunocompromised individuals. In this study, we retrospectively analyzed 108 non-immunocompromised patients diagnosed with VZV central nervous system infection.
Methods: This retrospective study was conducted in the Department of Neurology, Affiliated Nanjing Brain Hospital, Nanjing Medical University, China.

Cerebrospinal fluid (CSF) plays a crucial role in maintaining brain homeostasis by facilitating the clearance of metabolic waste and regulating intracranial pressure. Dysregulation of CSF flow can lead to conditions like syringomyelia, and hydrocephalus. This review details the anatomy of CSF flow, examining its contribution to waste clearance within the brain and spinal cord.

Spinal cord injury (SCI) can cause permanent dysfunction proceeding from multifaceted neuroinflammatory processes that contribute to damage and repair. Fidgetin-like 2 (FL2), a microtubule-severing enzyme that negatively regulates axon growth, microglial functions, and wound healing, has emerged as a potential therapeutic target for central nervous system injuries and neuroinflammation. To test the hypothesis that FL2 knockdown increases acute neuroinflammation and improves recovery after SCI, we examined the effects of nanoparticle-encapsulated FL2 siRNA treatment after a moderate contusion SCI in rats.
