Immunostimulatory activity of QD assemblies. A human microglia-like cell line (hμglia) was transfected, and cell supernatants were collected 24 h later. Levels of hIL-1β, hIL-6, hIL-8, and hIFN-β were assessed by ELISA. Bars denote mean ± SEM of n = 3 independent repeats. Statistically significant results are indicated with asterisks (**** = P-value < 0.0001, *** = P-value < 0.001, and * = P-value < 0.05).
