Fig. 1From: Natural killer cells and their exosomes in viral infections and related therapeutic approaches: where are we?Viral infections have different ways of evading the immune response by the NK cells. A They can alter the proportion of ligands on the cell surface of infected cells to change the NK cell response after interacting with the infected cells from activation to inhibition. BÂ Also, they can use cytokines and viral proteins to send inhibitory signals to the NK cells. CÂ Some viruses can also directly infect the NK cells and induce apoptosisBack to article page
