CD28‐Targeted Enzyme‐Responsive Conformation‐Switching Peptide Self‐Assembly for Selective T‐Cell Acute Lymphoblastic Leukemia (T‐ALL) Therapy

open access: yesAdvanced Science, EarlyView.
We developed the enzyme‐responsive peptide SAp‐CD28 to selectively target CD28‐overexpressing T‐ALL cells. Following phosphatase‐mediated activation, SAp‐CD28 undergoes conformational switching and nanooligomerization, resulting in the disruption of CD28 downstream signaling.

Mitochondria in DRG neurons undergo hyperglycemic mediated injury through Bim, Bax and the fission protein Drp1

open access: yesNeurobiology of Disease, 2006
Dorsal root ganglia (DRG) neurons degenerate in diabetic neuropathy (DN) and exhibit mitochondrial damage. We studied mitochondria of cultured DRG neurons exposed to high glucose as an in vitro model of DN.

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.

Dynamin-like proteins are essential for vesicle biogenesis inMycobacterium tuberculosis

open access: yes, 2020
ABSTRACTMycobacterium tuberculosis (Mtb)secretes pathogenicity factors and immunologically active molecules via membrane vesicles. However, nothing is known about the mechanisms involved in mycobacterial vesicle biogenesis. This study investigates molecular determinants of membrane vesicle production inMtbby analyzingMtbcells under conditions of high ...

Mitochondrial Enzymes Mimetic Ultrasmall Palladium Nanozymes Prevent Senescence and Neurodegeneration Through Metabolic Reprogramming

open access: yesAdvanced Science, EarlyView.
Simply constructed polyvinylpyrrolidone (PVP) modified palladium nanoparticles (PdP NPs) as cytochrome c oxidase (CcO) and superoxide dismutase (SOD) mimic are promising multifunctional nanoreactors to boost mitochondrial respiration chain function and refine homeostasis via regulation of mitochondrial dynamics and proteostasis sensor UPRmt, which ...

Capsaicin protects neuromuscular junctions from the inhibitory effects of botulinum neurotoxin A [PDF]

open access: yes, 2008
Within 24 hrs after injecting botulinum neurotoxin A (BoNT/A) into the hindlimb, mice lost the toe spread reflex and developed progressive muscle weakness. At the same time, the compound muscle action potential amplitude decreased. Injection of capsaicin

Synthesis and Biological Characterization of a New Norbormide Derived Bodipy FL-Conjugated Fluorescent Probe for Cell Imaging [PDF]

open access: yes, 2018
Background: Norbormide (NRB) is a selective rat toxicant endowed with vasoconstrictor activity confined to the rat peripheral arteries. In a recent work we used a fluorescent derivative of NRB (NRB-AF12), obtained by coupling the NBD fluorophore to the ...

Adversarial Erasing Enhanced Multiple Instance Learning (siMILe): Discriminative Identification of Oligomeric Protein Structures in Single Molecule Localization Microscopy

open access: yesAdvanced Intelligent Systems, EarlyView.
Hallgrimson et al. introduce a machine learning algorithm, siMILe, that takes features of single‐molecule localization microscopy localization clusters (e.g., size and sphericity) and finds the clusters that are associated with certain cell conditions (such as differential protein expression or drug treatment).

Protein trafficking through the endosomal system prepares intracellular parasites for a home invasion [PDF]

open access: yes, 2013
Toxoplasma (toxoplasmosis) and Plasmodium (malaria) use unique secretory organelles for migration, cell invasion, manipulation of host cell functions, and cell egress. In particular, the apical secretory micronemes and rhoptries of apicomplexan parasites

Akt/PKB Controls the Activity-Dependent Bulk Endocytosis of Synaptic Vesicles [PDF]

open access: yes, 2012
Activity-dependent bulk endocytosis (ADBE) is the dominant SV endocytosis mode during intense neuronal activity. The dephosphorylation of Ser774 on dynamin I is essential for triggering of ADBE, as is its subsequent rephosphorylation by glycogen synthase
