The first is that activated microglia have an increased capability to uptake scrapie agents and to present them to neurons, implying that microglia act as bridge to reach neurons.
On the other hand, capability to uptake FITC-Daxtran of BMDCs was not affected by FC-98, suggesting that FC-98 might influence BMDCs maturation via other ways not the endocytosis.
The capability of Meiothermus to uptake DNA fragments is noticeably weaker than that of Thermus.
The administration of 100 μM Fe2 + (as ferrous ammonium sulfate; FAS) to fura-2 loastrocytescytes promoted a fast and marked fluorescence quenching (~ 30% reduction, 15 min after iron addition), comparable to neuronal counterpart [15], thus indicating the capability of astrocytes to uptake Fe2 +.
Of note, this competence pertains solely to DMT1 since acid-sensing ion channels are reported not to be expressed in the plasma membrane of hippocampal astrocytes [58,59] while the activation of TRP vanilloid 1 (TRPV1) nocisensors [60] with capsaicin did not modulate the capability of astrocytes to uptake iron (not shown).
Surprisingly, results clearly show that insoluble salts enhance the water progression and thereby increase the capability of the material to uptake water.
By tuning the number of amino-PEG molecules attached at the rod surface and thus by manipulating the resulting surface charge at different pHs, we tuned the capability of Hydra ectodermal cells to uptake QRs, from very high at acidic pH to zero at neutral pH.
The multi-Leu peptide, a PACE4-specific inhibitor, was further generated and its capability to be uptaken by tumor xenograft was demonstrated with regard to its PACE4 expression status.
Although S. aureus strains depending on external thiamine supply have been observed [35], there are no reports of thiamine uptake capabilities to date, which would – in additional to de novo synthesis - feed the intracellular thiamine pool in S. aureus.
PCL-NPs were selected for their biocompatibility, lipophilicity, cost-effectiveness and capability to support passive uptake processes, as compared with other polyesters, and were prepared by the nanoprecipitation technique.
