Nasal Mucosa‐Derived Extracellular Vesicles as a Systemic Antiaging Intervention

Advanced Science, EarlyView.
This study shows that nasal mucosa‐derived extracellular vesicles (nmEVs) exert systemic anti‐ageing effects in mice by restoring circadian rhythm, suppressing cellular senescence, and improving cognitive function. In aged human bone marrow mesenchymal stem cells, nmEVs reverse senescence‐associated phenotypes and reactivate core clock gene expression.

Fragments of Bacterial Endoglycosidase S and Immunoglobulin G Reveal Subdomains of Each That Contribute to Deglycosylation

Journal of Biological Chemistry, 2014
Background: Endoglycosidase S (EndoS) is an immune evasion factor from Streptococcus pyogenes that impedes IgG effector functions by deglycosylation. Results: Analysis of fragments of enzyme and substrate identify components of each that contribute to ...

Chronic ER Stress Triggers Cell‐Surface Chaperones as the Therapeutic Targets of CAR Cells in Acute Myeloid Leukemia

Advanced Science, EarlyView.
Acute myeloid leukemia (AML) remains a therapeutic challenge due to its heterogeneity and limited targets. Here, multi‐omics analyses are utilized, and it is revealed that AML cells, particularly the FLT3‐ITD+ subtype, undergo chaperone‐mediated ER stress, inducing surface translocation of ER chaperones.

Fc Engineering for Developing Therapeutic Bispecific Antibodies and Novel Scaffolds

Frontiers in Immunology, 2017
Therapeutic monoclonal antibodies have become molecules of choice to treat autoimmune disorders, inflammatory diseases, and cancer. Moreover, bispecific/multispecific antibodies that target more than one antigen or epitope on a target cell or recruit ...

Punicalagin Enhances Autophagy Through Sirtuin 1/FoxO3a Axis to Inhibit Intracellular Mycobacterium Abscessus Infection

Advanced Science, EarlyView.
Punicalagin, a pomegranate molecule, helps the body fight Mycobacterium abscessus. It preferentially boosts interstitial macrophages in the lung, stabilizing mitochondria and switching on the autophagy via SIRT1/FoxO3a, which lowers bacterial load without directly killing bacteria.

Erucic Acid, Derived by Lactobacillus Crispatus, Induces Ferroptosis in Cervical Cancer Organoids Through the PPAR‐δ Signaling Pathway

Advanced Science, EarlyView.
Utilizing PDO, cell lines and cervical cancer xenograft (CDX) models, the study demonstrate both in vitro and in vivo that the metabolite of L. crispatus, erucic acid, can modulate the proliferation, migration and invasion of cervical cancer by activating the PPAR‐δ pathway.

Intestinal Neutral Ceramidase Deficiency Triggers Regulatory T Cell Response via Gd3 to Protect the Host from Intestinal Inflammation

Advanced Science, EarlyView.
Deletion of ASAH2 in intestinal epithelial cells induces the accumulation of ganglioside GD3 via regulating ST8SIA1. GD3 is identified as the glycolipid ligand for the inhibitory receptor Siglec‐E on macrophages. GD3/Siglec‐E ligation polarizes macrophages and promotes the proliferation of colonic ST2+ T regulatory cells via the induction of IL‐33. The

Biochemical and structural characterization of the human gut microbiome metallopeptidase IgAse provides insight into its unique specificity for the Fab' region of IgA1 and IgA2.

PLoS Pathogens
Human immunoglobulin A (IgA), comprising the isotypes IgA1 and IgA2, protects ~400 m2 of mucosal surfaces against microbial infections but can also lead to aberrant IgA deposits that cause disease. Certain bacteria have evolved peptidases that cleave the
