an inflammation of the brain or tissues of the upper CNS
|
encephalitis
|
|
|
a group of proteins (cytokines) secreted by virus-infected and certain other cells that act to induce a specific set of cellular antiviral and intitumor responses in other cells

|
|
|
virus particles that are normal in appearance but cannot initiate a productive replication cycle
|
