Article Title: Dual-Ligand Targeted Nanoparticles Enhance In Vitro Delivery and Efficacy of Investigational Drug Candidate GAT211.
Article Snippet: We present a dual-ligand polymeric nanoparticle system engineered via coassembly of two distinct ligand-functionalized polymers, one conjugated with gambogic acid (GA) as a targeting ligand, and the other conjugated with naringenin (NAR), which functions dually as a therapeutic agent and targeting ligand.. This design enables simultaneous and synergistic targeting of transferrin receptors (TfR) and folate receptors (FR).. In vitro studies using fluorescently labeled nanoparticles revealed significantly enhanced cellular uptake and receptor colocalization for dual-ligand nanoparticles compared to their corresponding singleligand or nontargeted controls.

Impact of HBM on FHs74 Int cells. ( A ) Representative β-galactosidase staining of FHs74. cells exposed or not to NonCyt or Cyt-HBM. ( B ) Flow cytometry cell counts of viable (7-AAD negative) FHs74 cells recovered after exposure to different HBM samples. ( C ) Flow cytometry expression of Annexin V. Data are presented as Mean ± standard error of the mean (SEM); * p ≤ 0.05, ** p ≤ 0.01. n = 4–5 different HBM samples. Note: The difference in sample size between the FHs74-only condition (n = 4) and the HBM-treated conditions (n = 5) is due to the experimental design, in which multiple HBM donors were tested simultaneously against a single FHs74Int control within the same experiment. FHs74 = FHs74 intestinal cells alone; HBM = Human breast milk; FHs74 + FM = FHs74 intestinal cells exposed to formula milk; FHs74 + HBM = FHs74 intestinal cells exposed to human breast milk.

Techniques:

Toxoplasma gondii arrests primary human and bovine cells in the S-phase 24 h p.i. Three isolates of HUVEC, HFF, FHs74, BSIEC and BCEC were infected with T. gondii tachyzoites, and the samples were collected 24 h p.i. Fixed samples were stained with propidium iodide (PI) and analysed using FACS. Gating was performed by first selecting the cell population according to the shape and granularity. Then, the cell cycle phases were analysed using a histogram of the number of cells versus the PI signal. Cells in the first peak correspond to those in the G1-phase, the second peak to cells in the G2/M-phase, and cells in between the two peaks were cells in the S-phase. The results showed that all human cells were arrested in the S-phase ( A ), whilst only one bovine cell showed no effect on cell cycle progression before T. gondii infection ( B ). Graph bars represent the median ± SD of three biological replicates

Cell cycle arrest in T. gondii -infected cells is independent of the mitosis checkpoint protein control cyclin B1. Three donors of HUVEC, HFF, FHs74, BSIEC and BCEC were infected with T. gondii tachyzoites and fixed 24 h p.i. Cells were stained against cyclin B1 and an isotype control and analysed using FACS. Gating was done first by choosing the cell population and then selecting the same number of cells in each sample ( A ). The cyclin B1 signal was analysed as the mean of fluorescence (MOF) and plotted for non-infected and T. gondii- infected cells. The results showed that cyclin B1 was not affected after infection in any of the cell types studied ( B , C ). Graph bars represent the median ± SD of three biological replicates

Toxoplasma gondii infection affects the mitosis rate and the chromosome segregation at the mitosis phase. HUVEC, HFF, FHs74, BSIEC and BCEC were infected with T. gondii tachyzoites, and were fixed 24 h p.i. with PFA and stained against DAPI (chromosome marker, blue), γ-tubulin (centrosome marker, magenta) and T. gondii (green, asterisks). The mitosis index was counted as the total number of cells facing mitosis (see scheme) related to the total number of cells in the field of view. This percentage was calculated for the bovine ( A ) and human cell lines ( B ). The results showed that no bovine cell line studied here modified its mitosis rate after infection with T. gondii. However, FHs74 and HFF showed an increased proportion of mitotic cells . C The mitosis phases were followed by chromosome segregation, and the results showed that all cell lines developed chromosome segregation errors mainly due to an abnormal number of centrosomes (white arrows). Thereafter, the proportion of aberrant mitosis was determined in both bovine and human cells by counting the total number of aberrant mitoses relative to the total mitotic cells (normal and aberrant). The scale bar represents 5 µm

Toxoplasma gondii induces cytokinesis failure in human and bovine host cells. HUVEC, HFF, FHs74, BSIEC and BCEC were infected with T. gondii tachyzoites, and fixed 24 h p.i. with PFA and stained against DAPI (nuclear marker, blue), β-catenin (membrane marker, green) and T. gondii (red).
