The present research has been undertaken to study the therapeutic potential of mesenchymal stem cells (MSCs) for the treatment of neuroinflammation-induced cognitive disorders. Either umbilical cord or adipose MSCs were injected into mice treated with lipopolysaccharide. The mice were studied in behavioral tests, and their brains were examined by means of immunohistochemistry, electron microscopy and sandwich ELISA. MSCs, introduced either intravenously or intraperitoneally, restored episodic memory of mice disturbed by inflammation, normalized nAChR and Aβ levels and stimulated proliferation of neural progenitor cells in the brain. The effect of MSCs was observed for months, whereas that of MSC-conditioned medium was transient and stimulated an immune reaction. SDF-1α potentiated the effects of MSCs on the brain and memory. MSCs of different origins provide a long-term therapeutic effect in the treatment of neuroinflammation-induced episodic memory impairment.

Cerebral ischemia-reperfusion injury (CIRI) is a common and serious complication of reperfusion therapy in patients with ischemic stroke (IS). The regulation of microglia-mediated neuroinflammation to control CIRI has garnered considerable attention. The balance of iron metabolism is key to maintaining the physiological functions of microglia.

Objective: This study aims to elucidate the mechanisms by which nanovesicles (NVs) transport curcumin(CUR) across the blood-brain barrier to treat hypothalamic neural damage induced by heat stroke by regulating the expression of poly(c)-binding protein 2 (PCBP2).
Methods: Initially, NVs were prepared from macrophages using a continuous extrusion method. Subsequently, CUR was loaded into NVs using sonication, yielding engineered cell membrane Nanovesicles loaded with curcumin (NVs-CUR), which were characterized and subjected to in vitro and in vivo tracking analysis.

Macroautophagy, a universal cellular process, sends cellular material to lysosomes for breakdown and is often activated by stressors like hypoxia or drug exposure. It is vital for protein balance, neurotransmitter release, synaptic function, and neuron survival. The role of macroautophagy in substance use disorders is dual.

Neuroinflammation and oxidative stress are key factors leading to neuronal injury. In this study, we investigated the role of S32, a novel 3-acetylaminocoumarin compound, in ameliorating neuronal injury induced by neuroinflammation and oxidative stress and . First, we found that S32 reduced the expression levels of p-P65 and p-P38, inhibited the nuclear translocation of P65, and lowered the levels of pro-inflammatory factors in LPS-induced BV2 cells, which indicated that S32 had an antineuroinflammatory effect.
