Clonal deletion that removes lymphocytes that recognize any self antigens that are present is known as

Type ___________ hypersensitivity is generally called a cytolytic or cytotoxic reaction because it results in the destruction of host cells, either by lysis or toxic mediators.

The inability of a virus to bind to its target cell as a result of antibody binding to the virus is referred to as
