WebThey engulf the pathogen to form a vesicle, known as a phagosome. Lysosomes move toward the vesicle and fuse with it. Enzymes called lysozymes are present within the lysosomes. They destroy injested bacteria by hydrolysis of their cell walls. The soluble products from the breakdown of the pathogen are absorbed into the cytoplasm of the … WebVirally infected cells produce more viruses by synthesizing large quantities of viral proteins. Thus, by reducing protein synthesis, a cell becomes resistant to viral infection. Figure 23.4. Interferons are cytokines that are released by a cell infected with a virus. Response of neighboring cells to interferon helps stem the infection.
