Tailoring the Properties of Functional Materials With N‐Oxides

Advanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.

Inter-individual and inter-regional variability of breast milk antibody reactivity to bacterial lipopolysaccharides

Frontiers in Immunology
Breast milk is a vital source of nutrients, prebiotics, probiotics, and protective factors, including antibodies, immune cells and antimicrobial proteins. Using bacterial lipopolysaccharide arrays, we investigated the reactivity and specificity of breast

Bimetallic Nanoreactor Activates cGAS‐STING Pathway via mtDNA Release for Cancer Metalloimmunotherapy

Advanced Functional Materials, EarlyView.
A bimetallic Mn–Ca nanoreactor (MCC) is developed as a non‐nucleotide STING nanoagonist for cancer metalloimmunotherapy. MCC induces Ca2+ overload and hydroxyl radical generation, resulting in mitochondrial damage and mtDNA release. The released mtDNA cooperates with Mn2+ to robustly activate cGAS–STING signaling.

Dynamics of Mycobacterium tuberculosis Ag85B Revealed by a Sensitive Enzyme-Linked Immunosorbent Assay

mBio, 2019
Secretion of specific proteins contributes to pathogenesis and immune responses in tuberculosis and other bacterial infections, yet the kinetics of protein secretion and fate of secreted proteins in vivo are poorly understood. We generated new monoclonal

A Single‐Metal‐Doped Nanoplatform for Ferroptosis‐Driven cGAS‐STING Pathway Activation in Hepatocellular Carcinoma Immunotherapy

Advanced Functional Materials, EarlyView.
The cGAS‐STING pathway boosts HCC antitumor immunity but lacks specific activation. Nanoplatform ZMRPF induces HCC ferroptosis via lipid ROS, releasing mtDNA. It synergizes with ZMRPF‐released Mn2⁺ to activate cGAS‐STING, amplifies antigen‐presenting cell activity, reverses HCC immunosuppression, and enables robust systemic antitumor immunity ...

Development of monoclonal antibodies against P. gingivalis Mfa1 and their protective capacity in an experimental periodontitis model

mSphere
Porphyromonas gingivalis (P. gingivalis), a gram-negative, black-pigmented anaerobe, is a major etiological agent and a leading cause of periodontitis. Fimbriae protein Mfa1 is a key virulence factor of P. gingivalis and plays a crucial role in bacterial
