Alisol A inhibits and stabilizes atherosclerotic plaques by protecting vascular endothelial cells.

Background And Aims: Dysfunction of endothelial cells represents a crucial aspect in the pathogenesis of atherosclerosis. The aim of this study was to explore the protective effects of alisol A on vascular endothelial cells and its possible mechanisms.

Methods: An atherosclerosis model was established by feeding ApoE-/- mice with high-fat chow.

Cabozantinib-encapsulated and maytansine-conjugated high-density lipoprotein for immunotherapy in colorectal cancer.

Advanced colorectal cancer (CRC) responds poorly to current adjuvant therapies, partially due to its immunosuppressive intestinal microenvironment. We found that myeloid-derived suppressor cells (MDSCs) were enriched in orthotopic tumors due to treatment-induced succinate release, which activated tuft cells and upregulated interleukin 25 (IL-25) and interleukin 13 (IL-13). We engineered a cabozantinib (Cabo)-encapsulated and maytansine (DM1)-conjugated synthetic high-density lipoprotein (CD-sHDL) to modulate the tumor microenvironment.

Novel RGD-decorated micelles loaded with doxorubicin for targeted breast cancer chemotherapy.

Nanotechnology has emerged as a promising innovative avenue for therapeutic intervention in cancer research. However, achieving satisfactory accumulation of nanoparticles in the tumor and fabricating optimized nanoparticles remain challenging. In this work, we developed a novel polymeric micelle system to actively target integrin receptors, which are usually overexpressed in breast cancer.

Microfluidic-Enabled Assembly of Multicomponent Artificial Organelle for Synergistic Tumor Starvation Therapy.

Artificial organelles (AOs) encapsulating enzymes are engineered to facilitate biocatalytic reactions for exerting therapeutic effects in various diseases. Exploiting the confinement effect, these catalytic properties exhibit significant enhancements without being influenced by the surrounding medium, enabling more efficient cascade reactions. In this study, we present a novel approach for synergistic tumor starvation therapy by developing multicomponent artificial organelles that combine enzymatic oncotherapy with chemotherapy.

Frontiers of Plant-derived Exosomes from Research Methods to Pharmaceutical Applications in Plant-based Therapeutics.

Exosomes have emerged as critical mediators of intercellular communication and various physiological processes between cells and their environment. These nano-sized vesicles have been extensively investigated and confirmed to exhibit multifunctionality in animal systems. In particular, they participate in intercellular signaling, influence disease progression, and exhibit biological activity.

Lipid nanoparticles as the drug carrier for targeted therapy of hepatic disorders.

The liver, a complex and vital organ in the human body, is susceptible to various diseases, including metabolic disorders, acute hepatitis, cirrhosis, and hepatocellular carcinoma. In recent decades, these diseases have significantly contributed to global morbidity and mortality. Currently, liver transplantation remains the most effective treatment for hepatic disorders.

Enhancing precision medicine: Bispecific antibody-mediated targeted delivery of lipid nanoparticles for potential cancer therapy.

The precise delivery of therapeutic agents to specific cell populations, including cancer cells, remains a target in modern medicine, to enhance treatment efficacy, while minimizing unintended side effects. This study presents a strategy utilizing bispecific antibodies for the targeted delivery of nucleic acid drugs to the surface of glucose-regulated protein 78 (GRP78)-overexpressing cancer cells. Strong binding affinity of the bispecific antibodies to GRP78-overexpressing cancer cells, including HEPG2 cells, confirmed the tumor-targeting potential of this platform.

Adenosine-modulating synthetic high-density lipoprotein for chemoimmunotherapy of triple-negative breast cancer.

Adenosine (ADO) is a common chemotherapy-associated immune checkpoint that hinders anti-tumor immunity-mediated efficacy of chemotherapy. Herein, we created a synthetic high-density lipoprotein (sHDL) by co-assembly of a doxorubicin (DOX)-apolipoprotein A1 mimetic peptide conjugate, PSB-603 (an A2BR inhibitor), phospholipid, and cholesterol oleate with a microfluidic-based method. The obtained DP-sHDL showed a self-promoted drug delivery to cancer cells via remodeling tumor microenvironment.

ATP-citrate lyase controls endothelial gluco-lipogenic metabolism and vascular inflammation in sepsis-associated organ injury.

Sepsis involves endothelial cell (EC) dysfunction, which contributes to multiple organ failure. To improve therapeutic prospects, elucidating molecular mechanisms of vascular dysfunction is of the essence. ATP-citrate lyase (ACLY) directs glucose metabolic fluxes to de novo lipogenesis by generating acetyl-Co-enzyme A (acetyl-CoA), which facilitates transcriptional priming via protein acetylation.

Creation of a ready-to-use brexpiprazole suspension and the inflammation-mediated pharmacokinetics by intramuscular administration.

Brexpiprazole (BPZ), which is approved for the treatment of schizophrenia and major depressive disorder, has the potential to meet diverse clinical needs. This study aimed to develop a long-acting injectable (LAI) formulation of BPZ that could provide sustained therapeutic benefits. A library of BPZ prodrugs was screened through esterification, and BPZ laurate (BPZL) was identified as an optimal candidate.

Silver-dendrimer nanocomposite as emerging therapeutics in anti-bacteria and beyond.

To develop next-generation nanomedicine, theranostic nanotherapeutic strategies are increasingly being emphasized. In recent years, it is observed that the effective lifetime of anti-bacterial and anti-cancer agent is diminishing, which undermines the economic incentives necessary for clinical development and therapeutic applications. Thus, novel formulations ought to not only kill drug resistant strains and cancerous cells but also inhibit their formation.

Multifunctional ROS-Responsive and TME-Modulated Lipid-Polymer Hybrid Nanoparticles for Enhanced Tumor Penetration.

Purpose: To enhance tumor penetration by formulation design and tumor microenvironment (TME) modulation, herein a novel reactive oxygen species (ROS)-responsive size/shape transformable lipid-polymer hybrid nanoparticle (LPN) has been fabricated for the co-delivery of an anticancer and collagen-inhibition drug.

Methods: A ROS-responsive poly(D, L-lactide)-thioketal-polyethylene glycol (PLA-TK-PEG) co-polymer was synthesized. LPNs were then fabricated by encapsulation of losartan (LST)-loaded micelles as the core to support paclitaxel (PTX)-loaded liposomes.
