Phosphoproteomic Analysis Reveals the Predominating Cellular Processes and the Involved Key Phosphoproteins Essential for the Proliferation of Toxoplasma gondii.

Purpose: To explore the essential roles of phosphorylation in mediating the proliferation of T. gondii in its cell lytic life.

Methods: We profiled the phosphoproteome data of T.

Toxoplasma gondii rhoptry protein (TgROP18) enhances the expression of pro-inflammatory factor in LPS/IFN-γ-induced murine BV2 microglia cells via NF-κB signal pathway.

Toxoplasma gondii, an opportunistic pathogenic protozoan, exhibits a strong predilection to infect the brain, causing severe neurological diseases, such as toxoplasmic encephalitis (TE), in immunocompromised patients. Microglia, the resident immune cells in the brain, is reported to play important roles in regulating the neuroinflammation mediated by T. gondii infection.

Light and Magnetic Dual-Responsive Pickering Emulsion Micro-Reactors.

Emulsion droplets can serve as ideal compartments for reactions. In fact, in many cases, the chemical reactions are supposed to be triggered at a desired position and time without change of the system environment. Here, we present a type of light and magnetic dual-responsive Pickering emulsion microreactor by coadsorption of light-sensitive titania (TiO) and super paramagnetic iron oxide (FeO) nanoparticles at the oil-water interface of emulsion droplets.

Polymer-Protein Conjugate Particles with Biocatalytic Activity for Stabilization of Water-in-Water Emulsions.

Water-in-water (w/w) emulsions are attractive microcompartmentalized platforms due to their outstanding biocompatibility. To address the main disadvantage of poor stability that hampers their practical application, here we report a novel type of polymer-protein conjugate emulsifier obtained by Schiff base synthesis to stabilize w/w emulsions. In particular, the proposed mild approach benefits the modification of proteins of suitable size and wettability as particulate emulsifiers retaining their bioactivity.

Light-Triggered Release from Pickering Emulsions Stabilized by TiO2 Nanoparticles with Tailored Wettability.

In this work, a new strategy for developing light-triggered Pickering emulsions as smart soft vehicles for on-demand release is proposed. Initially, UV-induced tailored wettability allows anchoring of TiO2 nanoparticles at the interface to prepare stable water in oil emulsions. Such emulsions show the efficacy of microencapsulation and controlled release by demulsification due to the hydrophilic conversion of the TiO2 nanoparticles using a noninvasive light irradiation trigger.

Switchable Pickering Emulsions Stabilized by Awakened TiO2 Nanoparticle Emulsifiers Using UV/Dark Actuation.

In this work, switchable Pickering emulsions that utilize UV/dark manipulation employ a type of smart TiO2 nanoparticle as emulsifiers. The emulsifiers can be awakened when needed via UV-induced degradation of grafted silanes on TiO2 nanoparticles. By tuning the surface wettability of TiO2 nanoparticles in situ via UV/dark actuation, emulsions stabilized by the nanoparticles can be reversibly switched between the water-in-oil (W/O) type and oil-in-water (O/W) type for several cycles.
