WebCytopathogenic definition, of or relating to a substance or microorganism that is pathologic for or destructive to cells. See more. WebClassical examples of the cytopathic effect. A well-known virus-induced CPE is cell death (check out a video of a dying cell in [1]). Many viruses kill cells either by lysis or by inducing apoptosis. For example, HIV is known for killing CD4+ T lymphocytes, which is the main reason why infected individuals become immunocompromised. sick cell phone backgrounds https://theinfodatagroup.com
