The rational design of self-assembled compounds is crucial for the highly efficient development of carrier-free nanomedicines. Herein, based on computer-aided strategies, important physicochemical properties are identified to guide the rational design of self-assembled compounds. Then, the pharmacophore hybridization strategy is used to design self-assemble nanoparticles by preparing new chemical structures by combining pharmacophore groups of different bioactive compounds.

Triple-negative breast cancer lacks enough immune cell infiltration, and adjuvant therapy is necessary to prime anti-tumor immunity. However, the improvement in efficacy is unsatisfactory with concern about inducing systemic immunotoxicity.

Compared to traditional microbiota regulation methods, prebiotics and probiotics demonstrate significant advantages in terms of safety and patient adaptability. Their synergy not only improves the intestinal environment but also enhances the host's anti-tumor immune response.

The physicochemical properties and unique behaviors of nanofilaments that are associated with multivalent interaction with protein are poorly understood. Here, peptide-based nanofilaments containing different homotetrapeptidic inserts are reported and their protein adsorption and biological fates are tested.

This transition facilitates the enhancement of efficiency in the preclinical discovery pipeline of nanomaterials, particularly in improving the hit rate of nanomaterials and the optimization efficiency of promising candidates. Herein, we describe a directed evolution mode of nanomedicines driven by data to accelerate the discovery of nanomaterials with high delivery efficiency.

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.

Combination of systemic chemotherapy and immune checkpoint blockade is effective but of limited benefit due to insufficient intratumoral infiltration of cytotoxic T lymphocytes (CTLs) and the accumulation of immunosuppressive cells. Herein, we designed a lenvatinib- and vadimezan-loaded synthetic high-density lipoprotein (LV-sHDL) for combinational immunochemotherapy of metastatic TNBC.

Objectives: The current study explored: (a) which alcohol-specific antecedents are the most salient predictors for alcohol use intentions, (b) whether any mediational relationships exist among these alcohol-specific antecedents, and (c) whether gender-based differences exist among these relationships.
