Advanced Science, EarlyView.ARHGEF3 is broadly downregulated across human cancers and correlates with patient prognosis. Tumor‐intrinsic ARHGEF3 activates the RHOA–ROCK–PTEN cascade to inhibit AKT signaling, thereby promoting chemokine‐driven T‐cell infiltration and relieving lipid‐mediated myeloid immunosuppression.

Optimization of B Cell Responses in Human Immune System Mice Through Organoid Based Screening
Advanced Science, EarlyView.Human immune system (HIS) mice show limited B cell responses to immunization. Using HIS mouse spleen organoids, this study identifies cytokine combinations and innate immune signals that drive human B cell expansion, differentiation, and class‐switch. Applying these signals in vivo through temporal separation enables antigen‐specific IgG responses and ...

Endogenous Engineering Reprograms Extracellular Vesicles for Enhanced Therapeutic Function
Advanced Science, EarlyView.This review explains how Extracellular vesicles‐producing cells can be endogenously engineered to load therapeutic proteins and nucleic acids. We summarize physiological and genetic strategies that harness native sorting pathways for selective cargo loading.

Advanced Science, EarlyView.We developed a RhPd‐H nanozyme that integrates enhanced POD‐mimetic catalytic activity with thermally triggered H2 release. H2 shields and reprograms mitochondria to continuously leak endogenous ·O2−. This dual‐path ROS spatially and temporally disrupts redox homeostasis, inducing persistent oxidative stress for tumor suppression and antitumor immunity,

DO11.10 CD4 T Cell Cross-Reacts with Trypanosoma cruzi Antigens
ParasitologiaAcute Trypanosoma cruzi infection induces an exuberant immune response; however, the host is unable to clear the parasite, and the infection progresses to a chronic phase. T and B cells play a crucial role in controlling infections. Although the parasite

Identification of CD4+T-Cell-Stimulating Antigens by Expression Cloning
Methods, 1996 The antigens recognized by CD4(+) T cells are key to rational vaccine design, but have been difficult to identify due to limitations of conventional methods. A novel strategy for identifying CD4(+) T-cell-stimulating antigen genes is described here. Using antigen-specific, lacZ-expressing T cells as single-cell probes, a DNA library was screened as ...

CD4 T cells inhibit the CD8 T cell response during low-dose virus infection.
, 2006 CD4 T cells are not thought to play a significant role in generating an effective primary CD8 T cell response to most viral infections. We have challenged this view by demonstrating that antigen-specific CD4 T cells can indeed suppress the proliferation ...

Engineering Microbial Particles for Next‐Generation Biomedical Platforms
Advanced Science, EarlyView.Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

Characterisation of Mycobacterium tuberculosis specific T cell immunity with HLA class II tetramers
, 2014 Includes bibliographical references.Tuberculosis (TB) remains a global health burden, with an estimated 1.3 million people dying from the disease in 2012. Protective immunity against TB is thought to depend on specific T cells.
