Lung cancer is one of the deadliest cancers in various populations. Apart from the effects that anticancer drugs such as paclitaxel (PTX) have on cancer cells, they also have many side effects on healthy cells. Interferon gamma (IFN-γ) is also one of the cytokines used in the treatment of cancer. Current research is focused on providing new drug carriers to find new therapeutic goals. After synthesis of nanogels and loading of PTX and IFN-γ, the cytotoxicity of these nanogels on A549 and HEK293 healthy cell line was measured by MTT assay and flow cytometry analysis. Finally, the expression of STAT1 gene was investigated using Real time-PCR. The results of MTT assay showed that the survival rate of healthy cells treated with PTX and IFN-γ-loaded nanogels was 2.15 and 2.39 times higher than cancer cells, respectively. The results also showed that the gene expression STAT1 in A549 cells exposed to these nanogels was higher than healthy cells (p < 0.05). Based on flow cytometry results, the death rate of healthy cells treated with the mentioned nanogels was lower than cancer cells (p < 0.05). Therefore, Studies showed that synthesized nanogels have positive effects on cancer cells and also have fewer side effects on healthy cells.
