The renin-angiotensin system (RAS) serves as a key regulator of body fluid balance and cardiovascular homeostasis, whose dysregulation is involved in the pathogenesis of various central nervous system (CNS) diseases. Beyond their canonical functions such as vascular regulation, the constituents of the RAS, particularly angiotensin (Ang) II, exert inflammatory and oxidative injury on neurons in the brain. Meanwhile, the non-classical pathway angiotensin-converting enzyme (ACE)2/Ang-(1-7) axis shows beneficial effects against CNS diseases. Activation of cerebral ACE2/Ang-(1-7) exerts regulatory effects on neurons, endothelial cells, glial cells, and other kinds, thereby comprehensively optimizing the blood-brain barrier (BBB), neurovascular unit, and cerebral microenvironment, and ultimately modulating memory, cognition, and emotion. This review, through comprehensive literature retrieval from PubMed and Web of Science, focuses on elucidating the critical regulatory role of the ACE2/Ang-(1-7) axis in CNS diseases and provides an in-depth exploration of its associated physiological and pathological mechanisms. Future research directions will primarily concentrate on novel drug development strategies targeting the ACE2/Ang-(1-7) axis, aiming to optimize drug development potential from multiple perspectives-including BBB penetration, targeted delivery to specific lesion sites, and regulation of pathological microenvironments and targets-to achieve early intervention, precision medicine, and efficient treatment for long-term CNS diseases.
BACKGROUND:Annexin A1 (ANXA1) can be activated by ischemia/reperfusion (I/R) events or inflammatory processes, but its specific regulatory mechanisms need further investigation. METHODS:ANXA1 in BV-2 cells was knocked down or overexpressed, and OGD/R induced injury, while 740YP and LY294002 were used for intervention. Microglia polarization phenotype and marker levels were assessed through flow cytometry, RT-qPCR and western blot. Autophagic flux and lysosomal function were evaluated by mCherry-GFP-LC3B, acridine orange (AO) staining and LysoTracker staining. ANXA1 and PI3K/Akt/mTOR proteins were detected by western blot. The tMCAO/R mouse model was established. Longa score, behavioral test and pathological staining to assess the extent of nerve injury, and microglia polarization and autophagy indicators were detected. RESULTS:ANXA1 expression was decreased in OGD/R-treated microglia. ANXA1 overexpression facilitated the transformation of microglia phenotype from M1-like phenotype to M2-like phenotype, increased CD206 and IL-10 expression, reduced the GFP/mCherry ratio and LysoTracker positive cells, and increased the red fluorescence of AO staining. ANXA1 overexpression also significantly reduced PI3K, Akt and mTOR phosphorylation. Moreover, ANXA1 overexpression markedly decreased Longa score, brain water content and infarct size, improved motor and neurological impairment in tMCAO/R mice, elevated Nissl bodies and Iba-1+CD206+ positive area, and reduced necrotic neuron numbers, inflammatory factor content and autophagy protein levels. In addition, 740YP significantly inhibited the improvement of ANXA1 overexpression, and LY294002 significantly enhanced the improvement of ANXA1 overexpression. CONCLUSION:Overexpression of ANXA1 regulated microglia polarization and autophagic flux via regulating PI3K/Akt/mTOR pathway, and improved cerebral I/R inflammatory injury.
BACKGROUND:Neuronal pyroptosis is involved in neuronal cell death and neurological damage after cerebral ischemia-reperfusion. 14,15-Epoxyeicosatrienoic acid (14,15-EET) can reduce neuronal loss induced by cerebral ischemia-reperfusion by regulating mitochondrial biological processes. However, it remains unclear how 14,15-EET regulates mitochondrial homeostasis, inhibits neuronal pyroptosis, and promotes neurological functional recovery after cerebral ischemia-reperfusion. METHODS:Mice with middle cerebral artery occlusion and reperfusion were used as an animal model to study the cerebral ischemia-reperfusion disease. The neurological function of mice was performed at 1, 3, and 5 days to test the therapeutic effects of 14,15-EET. Transmission electron microscope imaging and Nissl staining were used to analyze neuronal morphological structure, mitophagy, and neuronal pyroptosis. Western blot and transcriptome were used to detect the levels of mitophagy and neuronal pyroptosis signaling pathway-related molecules. HT22 cells were used in in vitro studies to detect the mechanism by which 14,15-EET reduces neuronal pyroptosis after oxygen-glucose deprivation/reoxygenation treatment. RESULTS:14,15-EET treatment reduced cerebral infarct volumes and improved neurological functional recovery in mice after cerebral ischemia-reperfusion. 14,15-EET treatment maintained the morphological structure of neurons in the ischemic penumbra area as well as the dendritic spine density in mice after cerebral ischemia-reperfusion. The upregulation of NLRP1 (NOD-like receptor thermal protein domain associated protein 1), IL (interleukin)-1β, caspase-1, and GSDMD (gasdermin D) induced by cerebral ischemia-reperfusion was inhibited, and the expression of mitophagy proteins Parkin and LC3B (microtubule-associated protein 1 light chain 3 B) was increased by 14,15-EET treatment. Transcriptome profiling found that 14,15-EET exerts a neuroprotection role in promoting neural function recovery by activating the WNT (wingless-type mouse mammary tumor virus integration site family) signaling pathway. We found that 14,15-EET upregulated the WNT pathway proteins such as WNT1, WNT3A, β-catenin, and p-GSK-3β (phosphorylation of glycogen synthase kinase 3β) in vivo and in vitro. The WNT signaling pathway inhibitor XAV-939 reduced the expression of mitophagy protein Parkin and upregulated the expression of caspase-1 and GSDMD in HT22 cells with oxygen-glucose deprivation/reoxygenation and 14,15-EET treatment. CONCLUSIONS:14,15-EET regulates mitochondrial homeostasis to inhibit neuronal pyroptosis, thereby promoting the recovery of neurological function in mice after cerebral ischemia-reperfusion. These results provide new ideas for maintaining mitochondrial homeostasis and inhibiting neuronal pyroptosis after cerebral ischemia-reperfusion.
The p110β isoform of the PI3 kinase (PI3K) family plays a key role in tumorigenesis and PTEN loss-driven multidrug resistance (MDR). Herein, we describe the design, synthesis, and structure-activity relationship studies of a series of small-molecule PI3K/110β PROTACs degraders by combining the selective inhibitor TGX221 of PI3K/110β with VHL ligands. Among them, J-6 and J-9 exhibited rapid and efficient degradation ability for the target proteins in MDR cells. Meanwhile, the expression and activity of P-glycoprotein were significantly inhibited, leading to a strong synergistic antitumor effect with adriamycin or cisplatin. Further studies confirmed that the two degraders can induce endoplasmic reticulum stress-mediated mitochondrial apoptosis by the AKT/Bcl-2 inhibition-mediated PERK/CHOP-unfolded protein reaction. In vivo studies also verified that the two degraders inhibited the growth of MCF-7/ADM xenograft tumors with high safety. Hence, this study and further optimization of these PI3K/110β PROTAC degraders have broad prospects for the development of new cancer therapies.
This study aims to explore the neuroprotective effect of bilobalide(BB) and the mechanisms such as inhibiting inflammatory response in macrophage/microglia, promoting neurotrophic factor secretion, and interfering with the activation and differentiation of peripheral CD4~+ T cells. BB of different concentration(12.5, 25, 50, 100 μg·mL~(-1)) was used to treat the RAW264.7 and BV2 cells for 24 h. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) assay and cell counting kit-8(CCK-8) were employed to detect the cytotoxicity of BB and appropriate concentration was selected for further experiment. Lipopolysaccharide(LPS) was applied to elicit inflammation in RAW264.7 and BV2 cells, mouse bone marrow-derived macrophages(BMDMs), and primary microglia, respectively. The effect of BB on cell proliferation and secretion of inflammatory cytokines and neurotrophic factors was detected by enzyme-linked immunosorbent assay(ELISA). Spleen monocytes of C57BL/6 female mice(7-8 weeks old) were isolated, and CD4~+ T cells were separated by magnetic beads under sterile conditions. Th17 cells were induced by CD3/CD28 and the conditioned medium for eliciting the inflammation in BMDMs. The content of IL-17 cytokines in the supernatant was detected by ELISA to determine the effect on the activation and differentiation of CD4~+ T cells. In addition, PC12 cells were incubated with the conditioned medium for eliciting inflammation in BMDMs and primary microglia and the count and morphology of cells were observed. The cytoto-xicity was determined by lactate dehydrogenase(LDH) assay. The result showed that BB with the concentration of 12.5-100 μg·mL~(-1) had no toxicity to RAW264.7 and BV2 cells, and had no significant effect on the activity of cell model with low inflammation. The 50 μg·mL~(-1) BB was selected for further experiment, and the results indicated that BB inhibited LPS-induced secretion of inflammatory cytokines. The experiment on CD4~+ T cells showed that the conditioned medium for LPS-induced inflammation in BMDMs promoted the activation and differentiation of CD4~+ T cells, while the conditioned medium of the experimental group with BB intervention reduced the activation and differentiation of CD4~+ T cells. In addition, BB also enhanced the release of neurotrophic factors from BMDMs and primary microglia. The conditioned medium after BB intervention can significantly reduce the death of PC12 neurons, inhibit neuronal damage, and protect neurons. To sum up, BB plays a neuroprotective role by inhibiting macrophage and microglia-mediated inflammatory response and promoting neurotrophic factors.

Subarachnoid hemorrhage (SAH) is one of the common clinical neurological emergencies. Its incidence accounts for about 5–9% of cerebral stroke patients. Even surviving patients often suffer from severe adverse prognoses such as hemiplegia, aphasia, cognitive dysfunction and even death. Inflammatory response plays an important role during early nerve injury in SAH. Toll-like receptors (TLRs), pattern recognition receptors, are important components of the body’s innate immune system, and they are usually activated by damage-associated molecular pattern molecules. Studies have shown that with TLR 4 as an essential member of the TLRs family, the inflammatory transduction pathway mediated by it plays a vital role in brain injury after SAH. After SAH occurrence, large amounts of blood enter the subarachnoid space. This can produce massive damage-associated molecular pattern molecules that bind to TLR4, which activates inflammatory response and causes early brain injury, thus resulting in serious adverse prognoses. In this paper, the process in research on TLR4-mediated inflammatory response mechanism in brain injury after SAH was reviewed to provide a new thought for clinical treatment.
Insomnia can cause damage to function and other medical and mental illnesses, and it is also a risk factor for increasing medical care costs. Although simple behavior intervention is feasible in primary medical institutions, the lack of corresponding technical training has obviously restricted its use, patients' autonomy dependence is generally poor, and early missions have some difficulties. Relatively speaking, acupuncture in traditional therapy is more likely to be accepted, but the mechanism is still unclear. In this study, a model of insomnia was constructed using chlorophenylalanine (PCPA) in 6-week-old male SD rats. Electroacupuncture was used to stimulate Baihui (DU20), Shenmen (HT7), and Sanyinjiao (SP6), and the behavior, histopathology, cAMP/CREB/BDNF, PI3K/Akt pathways and the expression of sleep-related factors were observed. Our study showed that IL-1β, PGD2, MT, IL-10, IL-6, TNF-α, IFN-γ and CORT in rats could be regulated after electroacupuncture stimulation. The expression of TrkB, PI3K, Akt, P-TrkB, p-Akt, cAMP, CREB, and BDNF can also be up- or downregulated. Apoptosis-related Bax, Bad and Caspase-3, as well as the monoamine neurotransmitters 5-HT, DA, NE and EPI, were also modulated by electroacupuncture. Taken together, these data illustrate the potential of DU20, HT7 and SP6 as a multitargeted therapy for insomnia in rats. The novelty of the study lies in the description of the Traditional Chinese Medicine stimulation methods different from Chinese Herbs: electroacupuncture stimulates acupoints of sleep factors, cAMP/CREB/BDNF, PI3K/Akt pathways and the multipath and multitarget body response regulation mechanism of apoptosis.

Neuroinflammation is considered as an important mechanism of vascular dementia (VaD). Our primary study showed that the bisindole analogue (2-(2-(bis(5-chloro-1H-indol-3-yl)methyl)phenoxy)aniline, compound 4ae) had great anti-inflammation in zebrafish. Rat model of permanent occlusion of the bilateral common carotid arteries (2-vessel occlusion, 2VO) was utilized to evaluate the neuroprotective effect of 4ae. Our results showed that 4ae treatment effectively reduced Iba-1 positive microglia cells in cerebral cortex and hippocampus after cerebral ischemia. Compared with the model group, neuroinflammation characterized by Interleukin (IL)-6 and tumor necrosis factor (TNF)-α, oxidative stress characterized by reactive oxygen species (ROS) and superoxide dismutase (SOD) were both improved significantly after treatment with 4ae. Moreover, 4ae treatment significantly reversed ischemia-induced ACE enhancement, while notably increased the level of ACE2. To further elucidate the role of 4ae on neuroinflammation, we investigated the effects of 4ae on lipopolysaccharide (LPS)-induced inflammation in BV2 microglia cells, a kind of innate immune cells in central nervous system. The results demonstrated that the expressions of CD11b, TNFα and IL-6 and the level of ROS were up-regulated after treatment with LPS. More importantly, 4ae was able to block the activation of BV2 by reducing ROS production and the expression of inflammatory cytokines. In addition, our results suggested that 4ae inhibited the inflammatory response mediated by microglia cells by inhibiting NF-κB. This anti-inflammatory effect on microglia may be a potential mechanism for the neuroprotective effect of 4ae in VaD.
