Tumor‐Derived Alpha‐1 Antitrypsin Promotes Liver Metastasis of Colorectal Cancer Through the Neutrophil Extracellular Traps–CCDC25 Pathway

Advanced Science, EarlyView.
ABSTRACT Liver metastasis is a leading cause of mortality in colorectal cancer (CRC), where the inflammatory tumor microenvironment, specifically neutrophil infiltration, significantly promotes metastatic colonization. This study reveals a pro‐metastatic role for alpha‐1 antitrypsin (A1AT) in CRC liver metastasis via a dual mechanism involving ...

Distinct plasmablast developmental intermediates produce graded expression of IgM secretory transcripts

Cell Reports
Summary: Differentiation into plasma cells (PCs) enables secretion of ∼10,000 immunoglobulin molecules per second. This extraordinary capacity requires the upregulation of PC transcriptional determinants that specify PC fate, increase immunoglobulin mRNA

Androgen Receptor‐Induced Lactoferrin Accelerates Prostate Tumorigenesis Through Modulating Ferroptosis

Advanced Science, EarlyView.
This study demonstrates that transcription factor androgen receptor (AR) directly binds the LF promoter, driving lactoferrin overexpression to promote ferritin (FTH1/FTL) upregulation and inhibit p53‐ALOX12‐mediated ferroptosis in prostate cancer. Lactoferrin could be a new potential therapeutic target in prostate cancer.

Prevalence and association of sIgA in saliva and Pseudomonas aeruginosa infection in TB patients: a cross-sectional study

Türk Biyokimya Dergisi, 2023
Pseudomonas aeruginosa is pathogenic in immunocompromised individuals. It has several complex mechanisms for evading human immunity. The objective of the study was to examine the secretory immunoglobulin A (sIgA) mediated immune response in saliva to ...

Legumain Restrains Granuloma Formation by Inhibiting mTORC1/STAT1‐Mediated M1 Macrophage Polarization in Sarcoidosis

Advanced Science, EarlyView.
Legumain (LGMN) is upregulated in macrophages during sarcoid‑like granuloma formation. Macrophage‑derived LGMN binds to integrin αvβ3 and suppresses mTORC1/STAT1 signaling to restrain M1 macrophage polarization. Intratracheal delivery of lipid nanoparticles carrying Lgmn plasmid DNA (pDNA) elevates LGMN expression and effectively attenuates pulmonary ...

Endogenous mammalian lectin localized extracellularly in lung elastic fibers. [PDF]

, 1984
An affinity-purified antibody preparation raised against a beta-galactoside-binding lectin from bovine lung was used to localize a similar lectin in rat lung by immunofluorescence and by electron microscopy after on-grid staining visualized with ...

Antigen Binding Properties of Purified Immunoglobulin A and Reconstituted Secretory Immunoglobulin A Antibodies [PDF]

Journal of Biological Chemistry, 1996
The hybridoma cell line ZAC3 expresses Vibrio cholerae lipopolysaccharide (LPS)-specific mouse IgA molecules as a heterogeneous population of monomeric (IgAm), dimeric (IgAd), and polymeric (IgAp) forms. We describe a gentle method combining ultrafiltration, ion-exchange chromatography, and size exclusion chromatography for the simultaneous and ...

Profiling Localized Immunomodulation and Drug Biodistribution within a Subcutaneous Vascularized Niche for Cell Transplantation

Advanced Science, EarlyView.
We studied how five common immunosuppressants behave when delivered directly to a transplant site instead of systemically. Using a vascularized implant for islet transplantation, we show that local delivery protects grafts, limits drug spread to the rest of the body, and produces distinct immune signatures.
