Specific mode electroacupuncture stimulation opens the blood-brain barrier of the infarcted border zone in rats during MCAO/R recovery via modulation of tight junction protein expression by VEGFA and NF-κB.

The blood-brain barrier (BBB) strictly limits the entry of most exogenous therapeutic drugs into the brain, which brings great challenges to the drug treatment of refractory central diseases, including the treatment of ischemic stroke. Our previous studies have shown that specific mode electroacupuncture stimulation (SMES) can temporarily open the BBB, but with the mechanisms largely unknown. This study explored whether SMES opens the BBB in the infarcted border zone of rats during middle cerebral artery occlusion/reperfusion recovery, and whether this is related to p65 or vascular endothelial growth factor A (VEGFA) modulation of tight junction protein expression through in vivo and in vitro studies.

Disulfiram/copper complex improves the effectiveness of the WEE1 inhibitor Adavosertib in p53 deficient non-small cell lung cancer via ferroptosis.

Cancer cells lacking functional p53 exhibit poor prognosis, necessitating effective treatment strategies. Inhibiting WEE1, the G2/M cell cycle checkpoint gatekeeper, represents a promising approach for treating p53-deficient NSCLC. Here, we investigate the connection between p53 and WEE1, as well as explore a synergistic therapeutic approach for managing p53-deficient NSCLC.

Albumin nanoparticles are widely used in biomedicine due to their safety, low immunogenicity, and prolonged circulation. However, incorporating therapeutic molecules into these carriers faces challenges due to limited binding sites, restricting drug conjugation efficiency. We introduce a universal nanocarrier platform (X-UNP) using polyphenol-based engineering to incorporate phenolic moieties into albumin nanoparticles.

Electroacupuncture stimulation enhances the permeability of the blood-brain barrier: A systematic review and meta-analysis of preclinical evidence and possible mechanisms.

An important cellular barrier to maintain the stability of the brain's internal and external environment is the blood-brain barrier (BBB). It also prevents harmful substances from entering brain tissue through blood circulation while providing protection for the central nervous system. It should be noted, however, that the intact BBB can be a barrier to the transport of most drugs into the brain via the conventional route of administration, which can prevent them from reaching effective concentrations for the treatment of disorders affecting the central nervous system.

Roles of immune microenvironment in the female reproductive maintenance and regulation: novel insights into the crosstalk of immune cells.

Female fertility decline is an accumulative consequence caused by complex factors, among them, the disruption of the immune profile in female reproduction stands out as a crucial contributor. Presently, the effects of immune microenvironment (IME) on the female reproductive process have attracted increasing attentions for their dynamic but precisive roles. Immunocytes including macrophages, dendritic cells, T cells, B cells and neutrophils, with diverse subpopulations as well as high plasticity functioned dynamically in the process of female reproduction through indirect intercellular communication via specific cytokine release transduced by molecular signal networks or direct cell-cell contact to maintain the stability of the reproductive process have been unveiled.

Signatures of tumor-associated macrophages correlate with treatment response in ovarian cancer patients.

Ovarian cancer (OC) ranks as the second leading cause of death among gynecological cancers. Numerous studies have indicated a correlation between the tumor microenvironment (TME) and the clinical response to treatment in OC patients. Tumor-associated macrophages (TAMs), a crucial component of the TME, exert influence on invasion, metastasis, and recurrence in OC patients.

Effects of microRNA-320 on learning and memory in mice with vascular cognitive impairment caused via cerebral ischemia.

We aimed to explore microRNA (miR)-320's impacts on learning and memory in mice with vascular cognitive impairment induced via cerebral ischemia. After establishment of a cerebral small vessel disease (CSVD) cognitive impairment model, application of corresponding treatment methods was in the model mice to inject miR-320 antagomir/agomir and their negative controls to the lateral ventricles: Test of the learning and memory abilities of mice was conducted; Detection of oxidative stress, inflammation, miR-320, Vascular endothelial growth factor (VEGF) and endostatin (ES) was implemented; Taking mouse hippocampal neuron cells was to detect the cell advancement. MiR-320 was elevated in the CSVD model; MiR-320 was negatively linked with the learning and memory abilities of mice; Repressing miR-320 was available to memorably elevate the learning and memory abilities of CSVD mice; Depressing miR-320 clearly drove CSVD mouse neovascular protein VEGF, but reduced inflammation, oxidative stress response and ES; Restraining miR-320 was available to contribute to mouse neuronal cell advancement.
