Abstract
Gold nanoparticles have been widely used in engineering, material chemistry, and biomedical applications owing to their ease of synthesis and functionalization, localized surface plasmon resonance (LSPR), great chemical stability, excellent biocompatibility, tunable optical and electronic property. In recent years, the decoration and modification of gold nanoparticles with small molecules, ligands, surfactants, peptides, DNA/RNA, and proteins have been systematically studied. In this review, we summarize the recent approaches on stimuli-triggered self-assembly of gold nanoparticles and introduce the breakthrough of gold nanoparticles in disease diagnosis and treatment. Finally, we discuss the current challenge and future prospective of stimuli-responsive gold nanoparticles for biomedical applications.

Spinal cord injury-activated C/EBPβ-AEP axis mediates cognitive impairment through APP C586/Tau N368 fragments spreading. Prog Neurobiol 2023; 227:102467. [PMID: 37257680 DOI: 10.1016/j.pneurobio.2023.102467] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2023] [Accepted: 05/25/2023] [Indexed: 06/02/2023]
Abstract
Spinal cord injury (SCI) leads to mental abnormalities such as dementia and depression; however, the molecular mechanism of SCI-induced dementia remains a matter of debate. Asparagine endopeptidase (AEP) mediated dementia by enhancing amyloid plaque and Tau hyperphosphorylation, indicating that it played an important role in neurodegeneration. Here we revealed that SCI stimulated AEP activation in mice with T9 contusion injury. Activated-AEP cleaved APP and Tau, resulting in APP C586 and Tau N368 formations, and consequentially accelerated Aβ deposit and Tau hyperphosphorylation, respectively. At 9 months following injury, mice demonstrated a severe deterioration in cognitive-behavioral function, which was corroborated by the presence of accumulated AD-specific pathologies. Surprisingly, activated AEP was found in the brains of mice with spinal cord injury. In contrast, AEP knockout reduced SCI-induced neuronal death and neuroinflammation, resulting in cognitive-behavioral restoration. Interestingly, compared to the full-length proteins, truncated Tau N368 and APP C586 were easier to bind to each other. These AEP-processed fragments can not only be induced to pre-formed fibrils, but also amplified their abilities of spreading and neurotoxicity in vitro. Furthermore, as a critical transcription factor of AEP, C/EBPβ was activated in injured spinal cord. Elevated C/EBPβ level, as well as microglia population and inflammatory cytokines were also noticed in the cortex and hippocampus of SCI mice. These neuroinflammation pathologies were close related to the amount of Tau N368 and APP C586 in brain. Moreover, administration with the AEP-specific inhibitor, compound #11, was shown to decelerate Aβ accumulation, tauopathy and C/EBPβ level in both spinal cord and brain of SCI mice. Thus, this study highlights the fact that spinal cord injury is a potential risk factor for dementia, as well as the possibility that C/EBPβ-AEP axis may play a role in SCI-induced cognitive impairment.

Abstract
The cysteine protease legumain (also known as asparaginyl endopeptidase or δ-secretase) is the only known mammalian asparaginyl endopeptidase and is primarily localized to the endolysosomal system, although it is also found extracellularly as a secreted protein. Legumain is involved in the regulation of diverse biological processes and tissue homeostasis, and in the pathogenesis of various malignant and nonmalignant diseases. In addition to its proteolytic activity that leads to the degradation or activation of different substrates, legumain has also been shown to have a nonproteolytic ligase function. This review summarizes the current knowledge about legumain functions in health and disease, including kidney homeostasis, hematopoietic homeostasis, bone remodeling, cardiovascular and cerebrovascular diseases, fibrosis, aging and senescence, neurodegenerative diseases and cancer. In addition, this review addresses the effects of some marketed drugs on legumain. Expanding our knowledge on legumain will delineate the importance of this enzyme in regulating physiological processes and disease conditions.

Abstract
Gold nanoparticles (AuNPs) present unique physicochemical characteristics, low cytotoxicity, chemical stability, size/morphology tunability, surface functionalization capability, and optical properties which can be exploited for detection applications (colorimetry, surface-enhanced Raman scattering, and photoluminescence). The current challenge for AuNPs is incorporating these properties in developing more sensible and selective sensing methods and multifunctional platforms capable of controlled and precise drug or gene delivery. This review briefly highlights the recent progress of AuNPs in biomedicine as bio-sensors and targeted nano vehicles.

The Asparaginyl Endopeptidase Legumain: An Emerging Therapeutic Target and Potential Biomarker for Alzheimer’s Disease. Int J Mol Sci 2022; 23:ijms231810223.

Abstract
Alzheimer’s disease (AD) is incurable dementia closely associated with aging. Most cases of AD are sporadic, and very few are inherited; the pathogenesis of sporadic AD is complex and remains to be elucidated. The asparaginyl endopeptidase (AEP) or legumain is the only recognized cysteine protease that specifically hydrolyzes peptide bonds after asparagine residues in mammals. The expression level of AEPs in healthy brains is far lower than that of peripheral organs. Recently, growing evidence has indicated that aging may upregulate and overactivate brain AEPs. The overactivation of AEPs drives the onset of AD through cleaving tau and amyloid precursor proteins (APP), and SET, an inhibitor of protein phosphatase 2A (PP2A). The AEP-mediated cleavage of these peptides enhances amyloidosis, promotes tau hyperphosphorylation, and ultimately induces neurodegeneration and cognitive impairment. Upregulated AEPs and related deleterious reactions constitute upstream events of amyloid/tau toxicity in the brain, and represent early pathological changes in AD. Thus, upregulated AEPs are an emerging drug target for disease modification and a potential biomarker for predicting preclinical AD. However, the presence of the blood–brain barrier greatly hinders establishing body-fluid-based methods to measure brain AEPs. Research on AEP-activity-based imaging probes and our recent work suggest that the live brain imaging of AEPs could be used to evaluate its predictive efficacy as an AD biomarker. To advance translational research in this area, AEP imaging probes applicable to human brain and AEP inhibitors with good druggability are urgently needed.
