Multifunctional Neutrophil Nanovesicles Induce Remodeling of Tumor Immune Microenvironment and Synergistic Multimodal Tumor Therapy

open access: yesAdvanced Functional Materials, EarlyView.
Schematic illustration of the engineered RN@FDT for multimodal tumor therapy. a) Fabrication of FD&DOX/TFA‐loaded RGD‐NNV (RN@FDT) and the light‐triggered disassemble of RN@FDT. b) After internalized by tumor cells, RN@FDT are disintegrated under NIR‐II laser irradiation to boost PTT and induce cell apoptosis.

Topically Delivered Treg‐Attracting Microparticle‐Hydrogel Composites Recruit Regulatory T Cells and Limit Cardiac Injury After Severe Ischemia

open access: yesAdvanced Healthcare Materials, EarlyView.
CCL22‐releasing PLGA microparticles (MP) suspended in topically applied hydrogels (HEART) establish a sustained chemokine gradient at the injured myocardium. HEART recruits CCR4+ regulatory T cells, reduces infarct size and graft fibrosis, and improves cardiac function.

Safety and immunogenicity of H1/IC31®, an adjuvanted TB subunit vaccine, in HIV-infected adults with CD4+ lymphocyte counts greater than 350 cells/mm3: a phase II, multi-centre, double-blind, randomized, placebo-controlled trial. [PDF]

open access: yes, 2014
BACKGROUND: Novel tuberculosis vaccines should be safe, immunogenic, and effective in various population groups, including HIV-infected individuals. In this phase II multi-centre, double-blind, placebo-controlled trial, the safety and immunogenicity of ...

Advanced Materials for Biologics Delivery to Brain Tumors

open access: yesAdvanced Materials, EarlyView.
Material innovation is central to unlocking the therapeutic potential of biologics against many central nervous system diseases, including brain cancer. By engineering carriers with controlled transport, targeting, and release properties, advanced materials can overcome the blood–brain barrier and tumor microenvironment, improving the delivery of ...

The role of ICOS in the development of CD4 T cell help and the reactivation of memory T cells [PDF]

open access: yes, 2007
We have addressed the role of the inducible costimulator (ICOS) in the development of T cell help for B cells and in the generation, survival and reactivation of memory CD4 T cells and B cells.

Photoacoustic Nanotagging for In Vivo Tracking and Optimization of Macrophage Immunotherapy in Solid Tumors

open access: yesAdvanced Materials, EarlyView.
Macrophage‐based immunotherapy for solid tumors is limited by poor tracking of cell localization and persistence. This study introduces nanotagged macrophages enabling near‐infrared photoacoustic imaging for real‐time monitoring. IFNγ‐conjugated tags enhance antitumor polarization without harming viability.

Complete Multilineage CD4 Expression Defect Associated With Warts Due to an Inherited Homozygous CD4 Gene Mutation

open access: yesFrontiers in Immunology, 2019
Idiopathic T-CD4 lymphocytopenia (ICL) is a rare and heterogeneous syndrome characterized by opportunistic infections due to reduced CD4 T-lymphocytes (<300 cells/μl or <20% T-cells) in the absence of HIV infection and other primary causes of ...

Bacteria‐Trained, MnO2‐Armored Dendritic Cells for Immunotherapy

open access: yesAdvanced Materials, EarlyView.
MnO2‐armored, bacteria‐trained dendritic cells undergo tumor‐responsive mechanical and immunological transformation. The nanocoating masks immune ligands and maintains a mechanically stiff, quiescent state during circulation, while the tumor microenvironment removes the armor and restores cellular deformability and immune accessibility.
