Evaluation of the plethora from the receptors over the cell surface area uncovered that AgNP treatment considerably reduced the current presence of Msr1, Compact disc33, Ager and Compact disc36 receptors (6 and 24 h), whereas CdTeQD elevated the degrees of Msr1 and Compact disc36 (24 h). In summary, we demonstrated that AgNP uptake competes using a uptake by microglial cells and therefore can impair removing the aggregates. Subsequently, CdTeQD treatment resulted in the deposition of proinflammatory Cd36 protein within the cell surface. and The reaction was carried out using Applied Biosystem 7500 Real-Time PCR System (Foster City, CA, USA). Reaction conditions were as follows: 95 C for 10 min, and then 40 cycles of 95 C for 15 s, followed by 60 C for 1 min. Data acquirement and analysis were performed using the Relative Quantification Software version 3.2.1-PRC-build1, (Thermo Fisher Medical, Waltham, MA, USA.) 2.8. Statistical Analysis Data are demonstrated as means SD of at least three self-employed experiments. Statistical variations between means were determined by one-way ANOVA, followed by Tukeys multiple assessment test or by combined value was 0.05. 3. Results 3.1. The Uptake of A and NP by Microglial Cells Uptake of A by microglia was visible as soon as 5 min after the addition of A, and its accumulation constantly improved during the 2-h observation period (Number 1). Similarly, the cells were able to uptake CdTeQD and AgNP (Number 2, Number 3, respectively). A and CdTeQD preferentially accumulated in the cytoplasm (Number 1 and Number 2).

BV-2 cells were incubated with A-HiLyte Fluor 488 (0.1 M) for 0, 5, 15, 30, 60 and 120 min. Fluorescence intensity at 528 nm was measured in six randomly selected cells using confocal microscope.

Localization of A in the cells organelles was visualized using fluorescent markers specific for mitochondria or lysosomes and confirmed by calculation of the Pearsons correlation coefficient (PCC) of both fluorescence distributions [25]. Colocalization between A and mitochondria (Number 4) was poor (PCC = 0.14 0.16, for 10 randomly selected cells). On the contrary, localization of A and the lysosome marker exposed significant similarities (Number 5) (PCC = 0.694 0.06, for 14 randomly selected cells).

Analysis of Gene Manifestation in BV-2 Cells Treated having a or NP RT PCR was used to assess the effect of NP within the manifestation of genes coding receptors of interest, i.e., and manifestation took place, whereas in the concentration of 10 g mL?1, a slight but significant increase in this genes manifestation was observed. Interestingly, treatment with 10 g mL?1 CdTeQD resulted in an almost four-fold increase in expression of gene (Table 1).
