Document Summary
Interferon: synthesized by virus-infected cells, binds to interferon receptor of nearby uninfected cells. Induces them to eliminate viral genome (rna) and black viral protein synthesis and replication: does not protect the original infected cell, does not prevent viruses from invading the protected cells. Interferon is not virus-specific: synthesis in response to one virus will also protect against other viruses, side effects. Interferon as a drug- it"s not a very successful drug at this level immunity or adaptive. Immunological memory: cellular (t cells, humoral (b cells) Antigens (ag) are substances that induce a specific immune response and subsequently react with the products of a specific immune response. Antibodies (ab, immunoglobulins, ig) are protein molecules that are produced by plasma cells in response to an antigen and can bind specifically to that antigen. Antibodies recognize foreign pathogens and help to destroy them http://www. northland. cc. mn. us/biology/bluetick/microbiology/online/animations/adaptive.
