Understanding the mechanism of Adenovirus endosomal escape

, 2020
Adenoviruses (AdV) are non-enveloped dsDNA viruses that cause respiratory and gastrointestinal diseases and are commonly used as vaccine and gene therapy vectors. In order to replicate inside a host cell, AdV must first penetrate the endosomal membrane and gain access to the cytosol. A highly conserved amphiphilic alpha helix within AdV protein VI (pVI)

Dynamic Shifts in ER–Plasma Membrane Junctions Signaling Define Pro‐Metastatic N‐Glycosylation and Predict Prostate Cancer Progression

Advanced Science, EarlyView.
Prostate cancer remains a leading cause of male cancer death, yet screening cannot reliably identify aggressive disease, underscoring the need for tissue biomarkers. It is shown that primary tumors increase ER–plasma membrane junction signaling via STIM1/ORP5, whereas metastasis features their loss, Golgi dispersal, and rapid conversion of high‐mannose

A biomimetic membrane platform for predictive screening and rational engineering of endosomally escaped lipid nanoparticle-CpG oligodeoxynucleotides delivery systems [PDF]

PeerJ
The efficient delivery of CpG oligodeoxynucleotides (CpG ODN) adjuvants is constrained by the limited endosomal escape capability of lipid nanoparticles (LNPs).

A Nanobody‐LNP Platform for Targeting and Relicensing Dendritic Cells for Potent Cancer Immunotherapy

Advanced Science, EarlyView.
Plastin‐2 (PLS2) is identified as a dual‐function receptor on DCs that mediates both nanoparticle uptake and immunomodulation. A nanobody‐LNP platform is engineered to integrate antigen delivery with relicensing DCs. The therapeutic strategy elicits potent anti‐tumor T cell responses and leads to significant inhibition of established tumors in vivo ...

Regulation of NKG2D-Dependent NK Cell Functions: The Yin and the Yang of Receptor Endocytosis. [PDF]

, 2017
Natural-killer receptor group 2, member D (NKG2D) is a well characterized natural killer (NK) cell activating receptor that recognizes several ligands poorly expressed on healthy cells but up-regulated upon stressing stimuli in the context of cancer or ...

Tumor‐Induced Splenic Remodeling: Mechanisms of Systemic Immunosuppression and Emerging Therapeutic Opportunities

Advanced Science, EarlyView.
ABSTRACT Despite the transformative impact of cancer immunotherapies such as immune checkpoint blockade, durable clinical responses remain limited. Increasing evidence indicates that antitumor immunity is governed not only by the tumor microenvironment, but also by systemic immune regulation mediated by peripheral immune organs. Among these, the spleen

ANXA2‐mediated Phagocytosis Generates AR+ Macrophages to Confer Enzalutamide Resistance in Prostate Cancer

Advanced Science, EarlyView.
A novel resistance mechanism is mediated through phagocytosis of cancer cells by AR+ TAMs. This process, dependent on ANXA2, enables macrophages to acquire AR protein from engulfed tumor cells. The internalized AR translocates into the macrophage nucleus, where it binds directly to the IL‐6 promoter, augmenting IL‐6 transcription and secretion ...

Reprogramming Antitumor Immunity: NK Cell Strategies to Navigate the Immunosuppressive Tumor Microenvironment

Advanced Science, EarlyView.
ABSTRACT Tumor immune escape is a major barrier to durable cancer immunotherapy, as advanced malignancies create a tumor microenvironment (TME) that preferentially exhausts and disables T cell responses. While most approved cell therapies are T cell‐based, this limitation motivates the exploration of an alternative effector cell platform.
