Piezo1 Channel Mediates Mechanically Programmable Drug Delivery to Potentiate Intravesical Chemotherapy

open access: yesAdvanced Science, EarlyView.
This study utilizes programmable mechanical pressure as a therapeutic enhancer to establish a mechano‐chemotherapy strategy. Controlled pressure activates the mechanosensitive ion channel Piezo1 in bladder cancer, triggering a calcium ion cascade that transiently and reversibly amplifies membrane permeability to chemotherapeutics.

Light‐Harvesting Photothermal Hotspots Enabled by NIR Scattering‐Absorption Coupling

open access: yesAdvanced Science, EarlyView.
By coupling the broadband scattering of nanodiamonds with the plasmonic absorption of gold nanostars, this work proposes a novel strategy for the active modulation of photon transport. This strategy creates localized photothermal hotspots in turbid media and achieves a supra‐additive heating efficiency, thereby providing a universal platform for low ...

Astrocytic Mitochondria Transplantation Rescues Neuron Loss and Dendritic Injuries in Acute Cerebral Ischemic Stroke Mouse Model by Flexibly Regulating Mitochondria Dynamics

open access: yesAnnals of Neurology, EarlyView.
Objective Cerebral ischemic stroke causes neuronal oxygen/energy deprivation, disrupting mitochondrial function including reduced membrane potential and bioenergetics, exacerbating neuronal injury. Mitochondrial defects are, therefore, a central neuropathological node and potential therapeutic target.

Mucin Glycoprotein Nanoparticles Enable a Selective Antisense Therapy for Oncogenic MicroRNAs

open access: yesAdvanced NanoBiomed Research, EarlyView.
Mucin glycoproteins are turned into nanoparticles by employing synthetic DNA strands, which have a dual function: they stabilize the nanoparticles and act as binding sites for intracellular miRNA‐21. Thus, upon internalization into tumor cells, these mucin nanoparticles can deplete miRNA‐21 from the cytosol, which induces apoptosis in vitro and in vivo.

SNX5 is essential for efficient macropinocytosis and antigen processing in primary macrophages

open access: yesBiology Open, 2012
Summary Macropinocytosis mediates the bulk endocytosis of solute molecules, nutrients and antigens. As this endocytic pathway is considered important in functions associated with immune responses, the molecular mechanisms regulating this pathway in ...

SLIT2/ROBO1-signaling inhibits macropinocytosis by opposing cortical cytoskeletal remodeling

open access: yesNature Communications, 2020
Macrophages survey their surroundings using macropinocytosis, but its regulation is unclear. Here, the authors report that SLIT2, a known inhibitor of Rac GTPases, is an endogenous inhibitor of macropinocytosis, and that SLIT2 limits the uptake of NOD2 ...

An Engineered Extracellular Vesicle With Enhanced Tumor and Lymph Nodes Targeting as siRNA Delivery System for Robust Tumor Immunotherapy. [PDF]

open access: yesMedComm (2020)
Simple incubation with DP7‐C enables the generation of extracellular vesicles (DP‐EVs) with enhanced both tumor and lymph nodes targeting properties. DP‐EVs/siPD‐L1 can effectively inhibit tumor growth and greatly prolong the survival of tumor bearing mice through immune response activation and tumor microenvironment reprogramming.

Calcium-sensing receptors signal constitutive macropinocytosis and facilitate the uptake of NOD2 ligands in macrophages

open access: yesNature Communications, 2016
Macropinocytosis can be induced in several cell types by growth factors to promote nutrient acquisition. Here the authors find that constitutive macropinocytosis, unique to dendritic cells and macrophages, requires the activity of calcium-sensing ...
