摘要
The outbreak of coronavirus disease 2019(COVID-19)is a significant challenge for clinicians,especially for immunocompromised cancer patients.By analyzing the impact of COVID-19 on the immune microenvironment of colorectal cancer(CRC)patients at the tissue level and single-cell level,we found that CRC patients are more easily infected by severe acute respiratory syndrome coronavirus-2(SARSCoV-2),but promotion of infiltration and differentiation of monocytes makes them more likely to develop severe COVID-19.Because of the continuing activation of nuclear factor(NF)-κB and C-C chemokine receptor type 5(CCR5)signaling pathways in monocytes,imbalance of macrophage polarization can aggravate the cytokine release syndrome.Therefore,regulating the infiltration and differentiation of monocytes is helpful for the treatment of COVID-19 in CRC patients.
