A Critical Call for Mechanistic Investigations of Metal‐Bacteria Interactions

Advanced Materials, EarlyView.
It is well established that the antibacterial properties of metals have tremendous importance for bioengineering applications. What is not as appreciated, however, is the reproducibility crisis in this field's vast literature. In this perspective, we highlight this reproducibility problem, discuss its sources, and suggest solutions towards focused ...

Natural Killer Cells Suppress T Cell-Associated Tumor Immune Evasion

Cell Reports, 2019
Summary: Despite the clinical success of cancer immunotherapies, the majority of patients fail to respond or develop resistance through disruption of pathways that promote neo-antigen presentation on MHC I molecules.

Synchronized Ablation of Multifocal Tumors Enabled by Multi‐Channel Lanthanide Nanocomposites

Advanced Materials, EarlyView.
A multi‐channel lanthanide nanocomposite enables orthogonal monitoring of tumor pH, glutathione, and temperature to guide customized therapy. Real‐time luminescence readouts determine a single irradiation protocol that synchronizes drug release and photothermal treatment, allowing efficient ablation of multifocal tumors while minimizing overtreatment ...

Natural killer cell-derived exosome-based cancer therapy: from biological roles to clinical significance and implications

Molecular Cancer
Natural killer (NK) cells are important immune cells in the organism and are the third major type of lymphocytes besides T cells and B cells, which play an important function in cancer therapy.

Activation mechanisms of invariant natural killer T cells (iNKTs)

Iatreia, 2016
A great amount of knowledge on natural killer T cells (iNKTs) is now available, but a consensus about their activation mechanisms has not been reached. These cells recognize different glycolipid antigens through the CD1d molecule.

Bacteria‐Trained, MnO2‐Armored Dendritic Cells for Immunotherapy

Advanced Materials, EarlyView.
MnO2‐armored, bacteria‐trained dendritic cells undergo tumor‐responsive mechanical and immunological transformation. The nanocoating masks immune ligands and maintains a mechanically stiff, quiescent state during circulation, while the tumor microenvironment removes the armor and restores cellular deformability and immune accessibility.

Proteasome inhibition induces apoptosis in primary human natural killer cells and suppresses NKp46-mediated cytotoxicity

Haematologica, 2009
Background Bortezomib is a selective and potent inhibitor of the proteasome and has prominent effects in vitro and in vivo against tumors. Very recently, cytotoxic effects of bortezomib on immune-competent cells such as T cells and dendritic cells were ...

Biomass DNA: An Emerging Building Block for Advanced Materials

Advanced Materials, EarlyView.
Biomass DNA is rapidly emerging from its traditional role as a genetic blueprint to serve as a versatile abundant, highly programmable polymeric building block. This review highlights the transformation of macroscopic bulk biomass DNA into next generation of functional materials, spanning from dynamic hydrogels, sustainable bioplastics, and high ...

GaSex Nanoparticles Modulate Neutrophil Function and Mitigate NET‐Driven Osteogenic Impairment in Osteomyelitis Therapy

Advanced Materials, EarlyView.
Neutrophil extracellular traps (NETs) emerge as a critical repair‐limiting factor in osteomyelitis, driving osteoblast mitochondrial dysfunction and excessive PINK1/Parkin‐mediated mitophagy. Gallium–selenium nanoparticles (GaSex) scavenge reactive oxygen species, redirect neutrophils from NETosis toward bactericidal phagocytosis, eliminate methicillin‐
