PGAM5 promotes RIPK1-PANoptosome activity by phosphorylating and activating RIPK1 to mediate PANoptosis after subarachnoid hemorrhage in rats.

Exp Neurol

February 2025

Department of Neurosurgery, The Fifth Affiliated Hospital of Sun Yat-sen University, Zhuhai, Guangdong, China; Guangdong Provincial Key Laboratory of Biomedical Imaging, The Fifth Affiliated Hospital, Sun Yat-sen University, Zhuhai, Guangdong, China. Electronic address:

Neuronal death plays a crucial role in early brain injury after subarachnoid hemorrhage (SAH). PANoptosis is a programmed form of cell death regulated by the PANoptosome, which possesses key characteristics of pyroptosis, apoptosis and necroptosis. Phosphoglycerate mutase family member 5 (PGAM5) has specific phosphatase activity that phosphorylates or dephosphorylates serine and threonine residues on bound proteins such as receptor-interacting protein kinase 1 (RIPK1), which are involved in programmed cell death.

Epigenetic regulation of the inflammatory response in stroke.

Neural Regen Res

November 2025

Laboratory for Clinical Medicine, Beijing Key Laboratory of Neural Regeneration and Repair, Capital Medical University, Beijing, China.

Stroke is classified as ischemic or hemorrhagic, and there are few effective treatments for either type. Immunologic mechanisms play a critical role in secondary brain injury following a stroke, which manifests as cytokine release, blood-brain barrier disruption, neuronal cell death, and ultimately behavioral impairment. Suppressing the inflammatory response has been shown to mitigate this cascade of events in experimental stroke models.

  • Memory consolidation during sleep depends on brain areas like the cortex, thalamus, and hippocampus, but how insomnia disrupts their metabolic patterns is still unclear.
  • This study investigates how insomnia affects metabolites related to memory consolidation, using both clinical research with human participants and experimental studies with rats.
  • Findings show that insomnia with mild cognitive impairment is associated with lower GABA levels, while sleep deprivation in rats worsens metabolic imbalances in the hippocampus, linking these changes to cognitive decline.
