Leveraging Organ‐on‐Chip Models to Investigate Host–Microbiota Dynamics and Targeted Therapies for Inflammatory Bowel Disease

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 10, April 15, 2025.
The challenges of studying inflammatory bowel disease (IBD), highlighting limitations of traditional 2D cell cultures and animal models are discussed here. It introduces human intestine organ‐on‐chip (OoC) models as a promising alternative, capable of more accurately mimicking the intestinal microenvironment.

Single-Cell RNA Sequencing Reveals T Helper Cells Synthesizing Steroids De Novo to Contribute to Immune Homeostasis

open access: yesCell Reports, 2014
T helper 2 (Th2) cells regulate helminth infections, allergic disorders, tumor immunity, and pregnancy by secreting various cytokines. It is likely that there are undiscovered Th2 signaling molecules.

Dirac Theory in Space-Time without Torsion [PDF]

open access: yesarXiv, 1994
It is proven that the usual quadratic general-covariant Lagrangian for the Dirac field leads to a symmetric, divergence-free energy-momentum tensor in the standard Riemannian framework of space-time without torsion, provided the tetrad field components are the only quantities related to gravitation that are varied independently.

Radiation‐Resistant Bacteria Deinococcus radiodurans‐Derived Extracellular Vesicles as Potential Radioprotectors

open access: yesAdvanced Healthcare Materials, EarlyView.
Deinococcus radiodurans‐derived extracellular vesicles (R1‐EVs) provide radioprotection against total‐body irradiation‐induced acute radiation syndrome in mice. R1‐EVs mitigate oxidative damage by scavenging free radicals, promoting intestinal repair, enhancing hematopoietic function, and modulating immune responses. This study highlights the potential

The host immune response to gastrointestinal nematode infection in sheep [PDF]

open access: yes, 2015
non peer reviewedGastrointestinal nematode infection represents a major threat to the health, welfare and productivity of sheep populations worldwide. Infected lambs have a reduced ability to absorb nutrients from the gastrointestinal tract, resulting in

Novel Less Toxic, Lymphoid Tissue‐Targeted Lipid Nanoparticles Containing a Vitamin B5‐Derived Ionizable Lipid for mRNA Vaccine Delivery

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
The top‐performing lipid nanoparticle, incorporating a novel ionizable lipid derived from vitamin B5, demonstrates high mRNA transfection efficiency, low toxicity, favorable stability, targeted delivery to lymphoid tissues, and high immunogenicity, showing promise as a carrier for mRNA vaccines for infectious diseases and cancer.

T follicular helper cells differentiate from Th2 cells in response to helminth antigens

open access: yesJournal of Experimental Medicine, 2009
The relationship of T follicular helper (TFH) cells to other T helper (Th) subsets is controversial. We find that after helminth infection, or immunization with helminth antigens, reactive lymphoid organs of 4get IL-4/GFP reporter mice contain ...

Enhancement of OVA-induced murine lung eosinophilia by co-exposure to contamination levels of LPS in Asian sand dust and heated dust. [PDF]

open access: yes, 2014
BackgroundA previous study has shown that the aggravation of Asian sand dust (ASD) on ovalbumin (OVA)-induced lung eosinphilia was more severe in lipopolysaccharide (LPS)-rich ASD than in SiO2-rich ASD.

Co‐Delivery of Multiple Toll‐Like Receptor Agonists and Avian Influenza Hemagglutinin on Protein Nanoparticles Enhances Vaccine Immunogenicity and Efficacy

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 10, April 15, 2025.
This research highlights a novel application of protein nanoparticles to effectively modulate the strength, breadth, and bias of an immune response against influenza virus. Nanoparticles precisely co‐delivering antigen (H5) and multiple adjuvants (CpG and FliCc) present a way to improve and direct prophylactic immune responses which can be applicable ...

Delayed Activation Kinetics of Th2- and Th17 Cells Compared to Th1 Cells

open access: yesCells, 2017
During immune responses, different classes of T cells arise: Th1, Th2, and Th17. Mobilizing the right class plays a critical role in successful host defense and therefore defining the ratios of Th1/Th2/Th17 cells within the antigen-specific T cell ...
