Real-time imaging of Leishmania mexicana-infected early phagosomes: a study using primary macrophages generated from green fluorescent protein-Rab5 transgenic mice [PDF]

, 2009
The small GTPase Rab5 is a key regulator of endosome/phagosome maturation and in intravesicular infections marks a phagosome stage at which decisions over pathogen replication or destruction are integrated.

Inhalability and Bioactivity of Spray‐Dried versus Pressurized Gas eXpanded Liquid Technology‐Processed Yeast Beta‐Glucan Microparticles for Anti‐Fibrotic Therapies

Advanced Healthcare Materials, EarlyView.
PGXTEC) liquid technology is utilized to develop highly respirable yeast beta‐glucan (YBG) microparticles for the treatment of pulmonary fibrosis. Compared to conventionally processed spray‐dried YBG, PGXTEC‐YBG exhibits greatly improved aerodynamic properties, enhanced pro‐fibrotic macrophage uptake, and effective downregulation of pro‐fibrotic ...

A phosphatidylinositol-3-kinase-dependent signal transition regulates ARF1 and ARF6 during Fcgamma receptor-mediated phagocytosis.

PLoS Biology, 2006
Fcgamma receptor (FcgammaR)-mediated phagocytosis of IgG-coated particles is regulated by 3'-phosphoinositides (3'PIs) and several classes of small GTPases, including ARF6 from the ADP Ribosylation Factor subfamily.

Integrin β4‐Enriched Small Extracellular Vesicle as Drug Delivery Vehicle for Targeting Pulmonary Metastasis of Hepatocellular Carcinoma

Advanced Healthcare Materials, EarlyView.
The expression of integrin β4 (ITGβ4) on small extracellular vesicle (sEV) correlates with lung‐tropism. Enrichment of ITGβ4 on sEVs enhances their lung‐targeting ability. The sEVs loaded with doxorubicin exhibit superior therapeutic efficacy in a lung metastasis mouse model.

Shedding Light on the Cellular Uptake Mechanisms of Bioactive Glass Nanoparticles as Controlled Intracellular Delivery Platforms: A Review of the Recent Literature

Advanced Healthcare Materials, EarlyView.
This review summarizes the main uptake pathways of bioactive glass nanoparticles (BGNs) and their intracellular localization, highlighting that BGNs are mainly internalized and entrapped within endosomes/lysosomes. Strategies for controlled intracellular ion release, with implications for targeted modulation of cell behavior, are discussed. The need to

Strategies to Improve the Lipophilicity of Hydrophilic Macromolecular Drugs

Advanced Healthcare Materials, EarlyView.
Hydrophilic macromolecular drugs can be successfully lipidized by covalent attachment of lipids, by hydrophobic ion pairing with negatively or positively charged surfactants, and by dry or wet reverse micelle formation. Lipophilicity enhancement of hydrophilic macromolecules has several benefits including stability and bioavailability improvement ...
