As we observed the changes in gene expression pattern which shifted the cell population dynamics from parasite-eliminating group to parasite survival cell subset starting at 6 h post-infection, we analyzed the chromatin accessibility of IL-10, IL-12p40, SHP-1, and NFAT5 and used B-actin and GAPDH as housekeeping gene control. The gene discussed is PTPN6; the disease is infection.
