Viral subversion of B-cell tolerance: mechanisms linking infection to autoimmunity

EMBO Reports
Viral infections are increasingly recognized as triggers of autoimmunity, yet the mechanisms linking viral infection to breakdown of B-cell tolerance remain incompletely understood. B-cell tolerance is maintained through sequential central and peripheral

Silk Fibroin Nanofiber–Immobilized Horseradish Peroxidase Enables Continuous Preparation of Injectable Hydrogels With Negligible Residual Enzyme for Drug Delivery

Advanced Materials Technologies, EarlyView.
Overcoming the immunogenicity challenges of enzyme‐mediated crosslinking, a flow‐through reactor utilizing SFNF‐HRP enables the continuous production of injectable hydrogels. This continuous platform ensures homogeneous crosslinking while minimizing residual HRP in the resulting hydrogels.

Dietary nucleic acids promote oral tolerance through innate sensing pathways in mice

Nature Communications
Oral tolerance is essential for intestinal homeostasis and systemic immune function. However, our understanding of how oral tolerance is maintained is inadequate.

Region‐Specific Profiling of the Gut Microbiome and Metabolite Landscape in Response to Dietary Intervention Using Electronics‐Free Ingestible Smart Sampling Capsules

Advanced Materials Technologies, EarlyView.
Region‐specific profiling of the gut microbiome is achieved non‐invasively using electronics‐free ingestible sampling capsules that activate at defined intestinal sites through stimuli‐responsive coatings. Deployed in a porcine dietary intervention model, the capsules resolve spatially distinct, fiber‐driven shifts in microbial composition and short ...

Regulatory T cell proliferative potential as novel marker to investigate immune tolerance and clinical progression in Multiple Sclerosis [PDF]

, 2011
In autoimmune disorders such as Multiple Sclerosis (MS) one of the determining alteration is the breakdown of self-antigen immune-tolerance. Peripheral immune tolerance is maintained, at least in part, by Regulatory T cells (Treg).

Systemic Immunological Tolerance to Ocular Antigens Is Mediated by TRAIL-Expressing CD8+ T Cells

, 2011
Systemic immunological tolerance to Ag encountered in the eye restricts the formation of potentially damaging immune responses that would otherwise be initiated at other anatomical locations.

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

Advanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

Intelligent Sky Guardians (InSkyGuard): An Aerial Robotic Swarm for Autonomous Detection and Entrapment of Rogue Multirotors

Advanced Robotics Research, EarlyView.
Intelligent Sky Guardians (InSkyGuard) is introduced as a four‐drone swarm that autonomously detects, tracks, and safely captures rogue drones using a coordinated net system. Computer vision and leader–follower control architecture enable synchronized enclosure, while integrated failsafes enhance system reliability. Validated through closed‐environment

GDF15 is dispensable for the insulin-sensitizing effects of chronic exercise

Cell Reports
Summary: Growth and differentiation factor 15 (GDF15) has recently emerged as a weight loss and insulin-sensitizing factor. Growing evidence also supports a role for GDF15 as a physiological, exercise-induced stress signal.
