Demonstrating the immunostimulatory and cytokine-augmentation effects of bacterial ghosts on natural killer cells and Caenorhabditis Elegans

  •  7 December 2023

Graphical Abstract

Description unavailable

Bacterial ghosts (BGs) from Staphylococcus aureus cells were derived through a simple pH-driven culture protocol. In NK-92 cells, the BGs exhibited significant activity as immuno-stimulants and as IL-12 adjuvant, influencing the gene expression of perforin, granzyme-B, Fas-L, and interferon-gamma, signifying heightened NK cell functionality. indicative of enhanced NK cell functionality. Innate response markers viz., lys-2 and ilys-3 were found to be upregulated in Caenorhabditis elegans following the ingestion of BGs, supporting their immuno-modulatory potential in this model organism.

Genome‐wide CRISPR/Cas9 knockout screening to mitigate cell growth inhibition induced by histone deacetylase inhibitors in recombinant CHO cells

  •  28 November 2023

Graphical Abstract

Description unavailable

Histone deacetylase inhibitors, such as CI994, enhance therapeutic protein production, but hinder cell proliferation in recombinant CHO cell cultures. Here, knockout target genes conferring CI994 resistance were identified via virus-free genome-wide clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 knockout cell library. These target genes were subsequently validated through knockout experiments.
