Abstract: 

Changes in the cerebral microenvironment caused by acute ischemic stroke-reperfusion are the main obstacle to the recovery of neurological function and an important cause of stroke recurrence after thrombolytic therapy. The intracerebral microenvironment after ischemia-reperfusion reduces the neuroplasticity of the penumbra and ultimately leads to permanent neurological damage. To overcome this challenge, we developed a triple-targeted self-assembled nanodelivery system, which combines the neuroprotective drug rutin with hyaluronic acid through esterification to form a conjugate, and then connected SS-31, a small peptide that can penetrate the blood brain barrier and target mitochondria. Brain targeting, CD44-mediated endocytosis, hyaluronidase 1-mediated degradation, and the acidic environment synergistically promoted the enrichment of nanoparticles and drug release in the injured area. Results demonstrate that rutin has a high affinity for ACE2 receptors on the cell membrane and can directly activate ACE2/Ang1-7 signaling, maintain neuroinflammation, and promote penumbra angiogenesis and normal neovascularization. Importantly, this delivery system enhanced the overall plasticity of the injured area and significantly reduced neurological damage after stroke. The relevant mechanism was expounded from the aspects of behavior, histology, and molecular cytology. All results suggest that our delivery system may be an effective and safe strategy for the treatment of acute ischemic stroke-reperfusion injury.

Abstract: 

Environmental factors may alter the fetal genome to cause metabolic diseases. It is unknown whether embryonic immune cell programming impacts the risk of type 2 diabetes in later life. We demonstrate that transplantation of fetal hematopoietic stem cells (HSCs) made vitamin D deficient in utero induce diabetes in vitamin D-sufficient mice. Vitamin D deficiency epigenetically suppresses Jarid2 expression and activates the Mef2/PGC1a pathway in HSCs, which persists in recipient bone marrow, resulting in adipose macrophage infiltration. These macrophages secrete miR106-5p, which promotes adipose insulin resistance by repressing PIK3 catalytic and regulatory subunits and down-regulating AKT signaling. Vitamin D-deficient monocytes from human cord blood have comparable Jarid2/Mef2/PGC1a expression changes and secrete miR-106b-5p, causing adipocyte insulin resistance. These findings suggest that vitamin D deficiency during development has epigenetic consequences impacting the systemic metabolic milieu.

Abstract: 

Stress-induced β2-adrenergic receptor (β2AR) activation in B cells increases IgG secretion; however, the impact of this activation on antibody affinity and the underlying mechanisms remains unclear. In the current study, we demonstrate that stress in mice following ovalbumin (OVA) or SARS-CoV-2 RBD immunization significantly increases both serum and surface-expressed IgG binding to the immunogen, while concurrently reducing surface IgG expression and B cell clonal expansion. These effects were abolished by pharmacological β2AR blocking or when the experiments were conducted in β2AR -/- mice. In the second part of our study, we used single B cell sorting to characterize the monoclonal antibodies (mAbs) generated following β2AR activation in cultured RBD-stimulated B cells from convalescent SARS-CoV-2 donors. Ex vivo β2AR activation increased the affinities of the produced anti-RBD mAbs by 100-fold compared to mAbs produced by the same donor control cultures. Consistent with the mouse experiments, β2AR activation reduced both surface IgG levels and the frequency of expanded clones. mRNA sequencing revealed a β2AR-dependent upregulation of the PI3K pathway and B cell receptor (BCR) signaling through AKT phosphorylation, as well as an increased B cell motility. Overall, our study demonstrates that stress-mediated β2AR activation drives changes in B cells associated with BCR activation and higher affinity antibodies.

Abstract: 

Inflammatory bowel disease (IBD) is a chronic condition with a high recurrence rate. To date, the clinical treatment of IBD mainly focuses on inflammation and gastrointestinal symptoms while ignoring the accompanying visceral pain, anxiety, depression, and other emotional symptoms. Evidence is accumulating that bi-directional communication between the gut and the brain is indispensable in the pathophysiology of IBD and its comorbidities. Increasing efforts have been focused on elucidating the central immune mechanisms in visceral hypersensitivity and depression following colitis. The triggering receptors expressed on myeloid cells-1/2 (TREM-1/2) are newly identified receptors that can be expressed on microglia. In particular, TREM-1 acts as an immune and inflammatory response amplifier, while TREM-2 may function as a molecule with a putative antagonist role to TREM-1. In the present study, using the dextran sulfate sodium (DSS)-induced colitis model, we found that peripheral inflammation induced microglial and glutamatergic neuronal activation in the anterior cingulate cortex (ACC). Microglial ablation mitigated visceral hypersensitivity in the inflammation phase rather than in the remission phase, subsequently preventing the emergence of depressive-like behaviors in the remission phase. Moreover, a further mechanistic study revealed that overexpression of TREM-1 and TREM-2 remarkably aggravated DSS-induced neuropathology. The improved outcome was achieved by modifying the balance of TREM-1 and TREM-2 via genetic and pharmacological means. Specifically, a deficiency of TREM-1 attenuated visceral hyperpathia in the inflammatory phase, and a TREM-2 deficiency improved depression-like symptoms in the remission phase. Taken together, our findings provide insights into mechanism-based therapy for inflammatory disorders and establish that microglial innate immune receptors TREM-1 and TREM-2 may represent a therapeutic target for the treatment of pain and psychological comorbidities associated with chronic inflammatory diseases by modulating neuroinflammatory responses.

Abstract:

Ferroptosis is an emerging antitumor treatment modality with the superiority for evading apoptotic cell death pathway. However, how to elevate catalytic efficacy of Fe2+-mediated Fenton reaction and efficiently elicit ferroptosis remain enormously challenging. Herein, inspired by hyperthermia-enhanced Fenton reaction kinetics, we firstly designed iron-polyphenol-aspirin-coordinated nanochelates for photothermal-enhanced ferroptosis antitumor immunotherapy. Specifically, we modulated optimal mass feeding ratio of gallic acid (GA), aspirin (ASA), Fe (II) and polyvinylpyrrolidone (PVP) to construct novel nanofibrous GA-ASA-Fe (II) metalchelates named GAFs. The variations in size and structure allowed the nanomedicines to avoid the risk of premature renal clearance in vivo, compared with the reported ultrasmall GA-Fe (II) nanocomplexes (GFs). Under NIR laser irradiation, GAFs could constantly amplify toxic hydroxyl radicals (radical dotOH) generation and deplete excessive GSH to induce more accumulation of lethal lipid peroxidation (LPO), thereby triggering ferroptosis pathway in vitro and in vivo. Besides, the introduction of ASA could inhibit cyclooxygenase-2 (COX-2) and prostaglandin E2 (PGE2), in combination with photothermal-enhanced ferroptosis tumor therapy to induce immunogenic cell death (ICD), promote maturation of dendritic cells (DCs) and activate cytotoxic T cells for synergistic antitumor immunotherapy. GAFs with laser irradiation exhibited the capacity of inhibition of pulmonary metastasis. This work presented a strategy for incorporating small molecule immunomodulator into the metal-polyphenolic coordination to ameliorate its deficiencies, thereby inspiring a new design concept for tumor treatment.

Abstract:

Smart hydrogel dressings capable of simultaneously highly effective antimicrobial, anti-inflammatory, and promoting re-epithelialization and angiogenesis are urgently needed for the management of diabetic wounds. Herein, a H2S-releasing multifunctional hydrogel was developed by utilizing the dynamic Schiff base reaction between carboxymethyl chitosan (CMC) and polyhexamethylene guanidine (PHMG)-modified aldehyde F108 (PFC). Diallyl trisulfide (DATS) was encapsulated into the PFC nanoparticles. Apart from possessing the essential properties necessary for an idealized hydrogel dressing, such as excellent injectability, tissue adhesion, self-healing, and stimulus–response degradation, the DATS@PFC&CMC also utilized the synergistic effect of the PHMG and DATS to provide an efficient antimicrobial effect; the H2S was slowly released from the DATS under the action of GSH and exerted excellent anti-inflammatory effects, by inhibiting the expression of p-ERK and p-STAT3 in activated macrophages, and promoting macrophage polarization to the M2 phenotype. Strikingly, following the completion of the efficient antimicrobial and anti-inflammatory effects, the continuously generated H2S further significantly accelerated the proliferation, migration, and vascularization of endothelial cells by extending the activation of the p-p38 and p-ERK1/2. Owing to superior performances, DATS@PFC&CMC significantly promoted the healing of diabetic wounds induced by streptozotocin with good biocompatibility. This study demonstrates that DATS@PFC&CMC is a versatile hydrogel dressing with great potential for the management of diabetic wounds.

Abstract:

Biosensors are rapid and portable detection devices with great potential for the instant screening of infectious diseases. Receptors are the critical element of biosensors. They determine the specificity, sensitivity and stability. However, current receptors are mainly limited to antibodies and aptamers. Herein, we developed a glycosylated extracellular vesicle-like receptor (GlycoEVLR) for the rapid detection of virus antigens, specifically using SARS-CoV-2 as a model. The human angiotensin-converting enzyme 2 (ACE2)-overexpressed and heparin-functionalized HEK-293T cell membrane-cloaked Fe3O4 nanoparticles (NPs) were prepared as functionalizing GlycoEVLR. They were characterized as spherical core–shell structures with a diameter of around 100 nm, which were perfectly comparable to natural extracellular vesicles. Binding affinities between GlycoEVLR and spike1 (S1) antigen were demonstrated using surface plasmon resonance (SPR). The GlycoEVLR was fixed on magnetic electrodes to construct electrochemical biosensors. Using electrochemical impedance spectroscopy (EIS) as a measurement technique, the S1 antigen was detected down to 1 pg/mL within 20 min and showed a good linearity range from 1 pg/mL to 1 ng/mL. Also, the GlycoEVLR-based electrochemical biosensors showed excellent antifouling performance and stability. Overall, our work provides a useful methodology for developing extracellular vesicle-like receptors for biosensors. Combining the inherit natural receptor proteins and antifouling lipids from the host cells with engineered glycan motifs to target and sense viral antigens will open a new avenue for biosensors.
