PROTAC‐Engineered Protein/DNA Nanoantigen is a Potent Booster for Dendritic Cell Vaccines in Cancer Immunotherapy

Advanced Science, EarlyView.
A PROTAC‐functionalized protein/DNA‐integrated nanoantigen platform is developed to enhance dendritic cell vaccine potency. By combining a VHL‐recruiting peptide‐modified antigen with a sustained expression plasmid within CaCO3 nanoparticles, this system amplifies cross‐presentation, promotes DC maturation, and elicits robust Th1 and CTL responses ...

Nicotinamide Metabolism Constrains Memory CD8+ T Cell Formation Through a Putative HS1BP3‐SIRT1‐FOXO3‐BCL6 Axis

Advanced Science, EarlyView.
ABSTRACT Memory T cells exhibit long‐term persistence, a defining feature that underpins durable clinical responses to adoptive immunotherapies. The mechanisms that integrate metabolic cues with transcriptional control of memory fate remain undetermined. Here, we identify HS1‐binding protein 3 (HS1BP3) is preferentially expressed in memory CD8+ T cells.

Salvinorin A inhibits ovalbumin‐stimulated allergic rhinitis and RBL‐2H3 cells degranulation

FEBS Open Bio, 2021
Allergic rhinitis (AR) is a long‐term noncommunicable inflammatory disease of the nasal mucosa mediated by immunoglobulin E and is mainly caused by exposure of genetically susceptible individuals to environmental allergens.

Intrasplenic Thymus Organogenesis from Injectable Tissue Fragments Restores Functional T‐Cell Immunity

Advanced Science, EarlyView.
Clinical intramuscular thymus transplantation yields only short‐lived efficacy and marginal therapeutic benefits. Benefiting from the spleen's intrinsic strengths—rapid vascular perfusion, abundant developmental factors, and resident progenitors—the intrasplenic thymic grafts achieve robust thymic regeneration and substantial T‐cell reconstitution ...

The alleviated symptoms in ovalbumin‐allergic mice treated with selenium‐enriched tea polysaccharide by modulation of intestinal flora and gut metabolites

Food Frontiers
Ovalbumin (OVA) in egg is one of the predominant causes of food allergy around the world. In the present study, the alleviating effect of selenium‐enriched tea polysaccharide (Se‐TPS) on OVA allergy was evaluated, and the underlying mechanistic insights ...

An Engineered HR1‐Stem Helix‐HR2 Trimeric Platform for Developing Broad‐Spectrum Coronavirus Vaccines

Advanced Science, EarlyView.
Sun et al. report a self‐assembling trimeric subunit vaccine platform termed RHS, which integrates the JN.1 receptor‐binding domain (RBD) with the heptad repeat 1 (HR1), stem helix (SH), and heptad repeat 2 (HR2) regions. The SARS‐CoV‐2 RHS vaccine elicits variant‐reactive RBD‐specific antibodies and cross‐reactive SH‐specific antibodies against ...

Macrophage Trogocytosis of Tumor Cells Drives the Immunosuppression of Tumor Microenvironment

Advanced Science, EarlyView.
Trogocytosis efficiency varies significantly among different tumor cells and is inversely related to their cortical stiffness; this efficiency dictates the extent of immunosuppression via upregulation of CXCL5 and Arg‐1, ultimately driving CD8+T cell exhaustion and tumor escape.

The effects of ovalbumin as a protein source during the in vitro production of bovine embryos

Revista Brasileira de Zootecnia, 2011
Embryo quality is influenced by the culture conditions that affect in vitro maturation (IVM), fertilization (IVF) and culture (IVC) rates. The present study investigated the feasibility of producing bovine embryos after the replacement of fetal calf ...

Non‐Invasively Quantitative Raman Imaging for Calculation of Lymphatic Transport Kinetics of Micelles in Mice

Advanced Science, EarlyView.
Non‐invasively quantitative Raman imaging with stacking‐induced charge transfer‐enhanced Raman scattering (SICTERS) enables accurate measurement of concentrations and pharmacokinetic modeling of lymphatic transport of micelles in mice. This platform allows dynamic analysis of nanoparticle transport and underpins the design of effective lymph node ...

Immune Checkpoint Inhibitor as a Fifth Component of Lipid Nanoparticles Enables Lymph Node‐Targeting and Augments mRNA Vaccine Efficacy

Advanced Science, EarlyView.
Here, a PDL1 inhibitor is employed as a fifth component to modify lipid nanoparticles (LNPs). PDL1 inhibitor‐loaded LNPs show enhanced lymph node targeting, resulting in greater lymph node expansion, immune cell infiltration, and improved mRNA vaccine efficacy. This fifth component LNP could be a novel platform for mRNA vaccines.
