Nanogel‐Mediated Immunotherapy to Tackle Cancer and Inflammatory Diseases

ChemistryEurope, EarlyView.
Nanogels formed through self‐assembly, microemulsion, or precipitation polymerization method enable precise delivery of immunotherapeutic factors and immune cell targeting, thus effectively modulating immune responses. This review highlights recent advances in stimuli‐responsive nanogel design, underlying mechanisms, and their potentials to tackle ...

Role of (p)ppGpp in Viability and Biofilm Formation of Actinobacillus pleuropneumoniae S8. [PDF]

, 2015
Actinobacillus pleuropneumoniae is a Gram-negative bacterium and the cause of porcine pleuropneumonia. When the bacterium encounters nutritional starvation, the relA-dependent (p)ppGpp-mediated stringent response is activated.

ARC Expands the DAAM1 Microexon‐Mediated Actin–RHOA/ROCK Interplay

Cytoskeleton, EarlyView.
ABSTRACT Actin cytoskeleton and its dynamics play a crucial role in synaptic function, influencing dendritic spines' structural and functional plasticity. Recent findings unveiled the significance of alternative splicing of a neural‐specific microexon in DAAM1 in modulating actin's role in synaptic processes.

Nucleotide-, chemotactic peptide- and phorbol ester-induced exocytosis in HL-60 leukemic cells [PDF]

, 1990
Undifferentiated and differentiated HL-60 leukemic cells possess nucleotide receptors which functionally couple to phospholipase C via pertussis toxin-sensitive guanine nucleotide-binding proteins (G-proteins).

Hypoxanthine-guanine phosphoribosyltransferase and inosine 5’-monophosphate dehydrogenase activities in three mammalian species: aquatic (Mirounga angustirostris), semiaquatic (Lontra longicaudis annectens) and terrestrial (Sus scrofa)

Frontiers in Physiology, 2015
Aquatic and semiaquatic mammals have the capacity of breath hold (apnea) diving. Northern elephant seals (Mirounga angustirostris) have the ability to perform deep and long duration dives; during a routine dive, adults can hold their breath for 25 min ...

Nano‐plastics disrupt systemic metabolism by remodeling the bile acid–microbiota axis and driving hepatic–intestinal dysfunction

iMeta, EarlyView.
The pervasiveness of microplastic pollution poses a growing health risk, yet its long‐term metabolic consequences remain poorly defined. Here, we exposed mice to polyethylene terephthalate nanoparticle (NP) and combined histopathology, biochemistry, metabolomics, and metagenomics to resolve their interactions.

Flexoelectric Polarization‐Enhanced Gd‐Based Nanoflowers for Efficient Phosphatase‐Mimicking Dephosphorylation

Small Structures, EarlyView.
Flexoelectric polarization is harnessed to dynamically enhance phosphatase‐mimicking catalysis in Gd‐based nanoflowers, enabling ultrasound‐responsive and efficient biophosphate ester hydrolysis through strain‐induced electronic modulation. Phosphatase‐mimicking nanozymes provide highly stable enzyme‐like activity but remain limited by their static ...

Evolution of the bacterial nucleosidase PpnN and its relation to the stringent response

Microbial Cell, 2019
In our recent publication (Zhang et al., 2019), we demonstrate an interesting mode of regulation of purine metabolism unique to Proteobacteria. In this microreview, we would like to reflect on the ideas put forward, with special focus on protein domain ...

An engineered epididymal cell line provides a sustainable source of functional extracellular vesicles for in vitro sperm preservation: A multi‐omics and functional study

VIEW, EarlyView.
ABSTRACT This study investigated the function of epididymal extracellular vesicles (EVs) in overcoming sperm post‐testicular modification deficiencies. Although EVs derived from the epididymis play a crucial role in intercellular communication and molecular exchange, there is limited research addressing how EVs released by in vitro cultured epididymal ...
