Mesenchymal Stem Cell‐Derived Apoptotic Micro‐Vesicles Repaired Sciatic Nerve Defect by Regulating Early Inflammatory Microenvironment and Promoting Angiogenesis

Advanced Healthcare Materials, EarlyView.
HUCMSC‐Apo‐mvs enhance peripheral nerve repair by modulating the inflammatory microenvironment (IME), primarily through coordinated actions on three functional cells. They recruit macrophages and promote their polarization from pro‐inflammatory M1 to anti‐inflammatory M2 phenotypes, increasing secretion of IL‐10 and VEGF.

AIF1+CSF1R+ MSCs, induced by TNF‐α, act to generate an inflammatory microenvironment and promote hepatocarcinogenesis

Hepatology, EarlyView., 2022
Mesenchymal stem cells subset, educated by TNF‐α, are involved to generate inflammatory microenvironment and promote hepatocarcinogenesis Abstract Background and Aims Increasing evidence suggests that mesenchymal stem cells (MSCs) home to injured local tissues and the tumor microenvironment in the liver.

Regulation of the immune response: III. The role of macrophages in the potentiation of the immune response by Fc fragments.

Journal of Immunology, 1981
The Fc fragment-induced enhancement of the anti-SRBC response was found to be dependent upon the presence of functional macrophages. Fc fragments derived from human immunoglobulin were unable to enhance either the in vivo or in vitro anti-SRBC response ...

Macrophages Mediate Mesoscale Brain Mechanical Homeostasis

Advanced Materials, EarlyView.
We investigated the role of infiltrating immune cells in sculpting the developing brain. Using Brillouin microscopy and active microrheology, we found microglia actively maintain tissue viscoelasticity. Moreover, colony stimulating factor one receptor (CSF1R)‐driven stromal remodeling alters brain mechanics in vivo. These findings link immune activity,

Structural Characterization and AI‐Enhanced Modeling of a Broadly Neutralizing Camelid Antibody Against SARS‐CoV‐2 Variants

Advanced Therapeutics, EarlyView.
This study characterizes a camelid antibody (B10) with potent neutralizing activity against SARS‐CoV‐2 Wildtype and Omicron variants. Through binding assays, epitope mapping, pseudovirus neutralization, and AI‐driven modeling, the antibody is shown to target conserved RBD regions in a closed Spike conformation.

Hierarchical Formation of Disulfide Bonds in the Immunoglobulin Fc Fragment Is Assisted by Protein-disulfide Isomerase [PDF]

Journal of Biological Chemistry, 2004
Antibodies provide an excellent system to study the folding and assembly of all beta-sheet proteins and to elucidate the hierarchy of intra/inter chain disulfide bonds formation during the folding process of multimeric and multidomain proteins. Here, the folding process of the Fc fragment of the heavy chain of the antibody MAK33 was investigated.

Predicting Immunotherapy Outcomes in NSCLC Using RNA and Pathology from Multicenter Clinical Trials

Advanced Science, EarlyView.
LIRA, a machine learning‐based model, is developed using transcriptomic data from 891 NSCLC patients in the OAK and POPLAR cohorts. Its predictive performance is validated in multiple external cohorts. Patients stratified by LIRA‐score exhibit distinct clinical characteristics and tumor microenvironment profiles.

Icaritin Ameliorates Cisplatin‐Induced Mitochondrial Metabolic Dysfunction‐Associated Nephrotoxicity and Synergistically Potentiates Its Antitumor Efficacy

Advanced Science, EarlyView.
In this study, scRNA‐seq and chemoproteomics are integrated to characterize CDDP‐bound proteins at single‐cell resolution in tumor‐bearing mice. Additionally, the research demonstrates that ICA alleviates CDDP‐induced nephrotoxicity while enhancing its chemotherapeutic efficacy.

Protective effects of an Fc-engineered PD-L1 fusion protein in a spontaneous abortion model and a Th17 cell–induced pregnancy loss model

Frontiers in Pharmacology
The binding of programmed death-ligand 1 (PD-L1) with its receptor PD-1 has been proven to negatively regulate immune responses. Here, we assessed the therapeutic effects of Fc-fused PD-L1 protein on foetomaternal tolerance using a murine spontaneous ...
