The microstructure of secondary lymphoid organs that support immune cell trafficking

Archives of Histology and Cytology, 2010
Immune cell trafficking in the secondary lymphoid organs is crucial for an effective immune response. Recirculating T cells constantly patrol not only secondary lymphoid organs but also the whole peripheral organs. Thoracic duct lymphocytes represent an ideal cell source for analyzing T cell trafficking: high endothelial venules (HEVs) allow ...

CCL3 and IL‐7 Synergistically Enhance CAR‐T Efficacy in Solid Tumors

Advanced Science, EarlyView.
Synergistic delivery of CCL3 and IL‐7 by CAR‐T cells overcomes the immunosuppressive tumor microenvironment by enhancing cell infiltration, survival, and local immune reprogramming. This also establishes positive feedback that amplifies anti‐tumor activity and memory responses in both CAR‐T and endogenous T cells, presenting a robust therapeutic ...

Tumor‐Specific Delivery of CD28 siRNA via Lyso‐PC C‐16 Modified Lipid Nanoparticles Overcomes Anti‐PD‐1 Resistance by Remodeling Tumor Microenvironment

Advanced Science, EarlyView.
This study develops 16:0 LPC‐modified lipid nanoparticles (LPC‐LNPs) with cancer cell specificity by exploiting altered tumor lipid metabolism. LPC‐LNPs encapsulating Cd28 small interfering RNA (LPC‐LNP‐Cd28) knock down cancer cell CD28 without affecting T cells, inflame the tumor microenvironment, and overcome anti‐PD‐1 resistance.

Skin matrix meets immunomatrix—Implications for genetic and acquired diseases

JEADV Clinical Practice
An extracellular matrix (ECM) is essential for multicellular life. Apart from being a scaffold, it is an actively signalling unit, orchestrating homo‐ and heterocellular communication to uphold tissue homeostasis or elicit an appropriate regenerative ...

Antigen Spreading via Localized Administration Enhances Adoptive TCR‐T Cell Therapy in Pancreatic Cancer

Advanced Science, EarlyView.
Cancer vaccines face limitations in pancreatic cancer due to insufficient tumor antigens. This ionic liquid ILvax via local tumor delivery triggers robust cDC1‐dependent systemic anti‐tumor immunity. It boosts endogenous CD8+ T cells and optimizes adoptive TCR‐T function, providing a promising synergistic therapeutic strategy.

Integrin-Alpha IIb Identifies Murine Lymph Node Lymphatic Endothelial Cells Responsive to RANKL.

PLoS ONE, 2016
Microenvironment and activation signals likely imprint heterogeneity in the lymphatic endothelial cell (LEC) population. Particularly LECs of secondary lymphoid organs are exposed to different cell types and immune stimuli.

Inhibition of KDEL Receptors Remodels the Tumor Microenvironment for T Cell Independent Tumor Regression

Advanced Science, EarlyView.
Inhibition of KDELR2 in a small fraction of tumor cells generates sustainable immunogenic cell death conditions within the tumor microenvironment. These conditions promote the regression of tumors in a T cell independent manner. During regression, macrophages prime T cells that subsequently provide systemic protection against recurrence. The potency of

Biomimetic Macrophage Cell Membrane‐Based Nanoparticles for Effective Treatment of Glioblastoma Through Boron Neutron Capture Therapy Combined With Immunotherapy

Advanced Science, EarlyView.
ABSTRACT Glioblastoma multiforme (GBM) remains largely incurable due to the blood‐brain barrier (BBB) and immunosuppressive microenvironment. While boron neutron capture therapy (BNCT) selectively eradicates tumor cells via 10B(n, α)‐7Li reactions, its clinical potential in GBM is unrealized because of the suboptimal pharmacokinetics of conventional ...

Material‐Encoded Synchronization of Immunogenic Cell Death With Adenosine A2A Receptor Blockade Reprograms the Tumor Microenvironment

Advanced Science, EarlyView.
A bismuth–copper diselenide–based nanoplatform (BSCS@PHY) coordinates immunogenic cell death with local A2A receptor blockade in 4T1 tumors. Thermally triggered shell melting exposes catalytic surfaces for glutathione depletion and chemodynamic ROS generation, while co‐delivering an A2AR antagonist and yeast‐wall adjuvant to enhance dendritic‐cell ...
