Immunoglobulin molecules that have an antigen-specific amino acid sequence and are synthesized by the humoral immune system (produced from B-cells) in response to exposure to a specific antigen, the purpose of which is to attack and destroy molecules of this antigen.
antibody
A substance, usually a protein, that is foreign to a host (e.g., human) and which causes the formation of an antibody and reacts specifically with that antibody. Examples include bacterial exotoxins and viruses...even allergens.
antigen
A more specific term for antiviral drugs that work against retroviruses such as human immunodeficiency virus (HIV).
antiretroviral agent
A general term for any drug that destroys viruses either directly or indirectly by suppressing their replication.

The cell-mediated immune system is one of two major parts of the immune system. It is mediated primarily by T-lymphcytes (T-cells) and other immune system cells (e.g., monocytes, macrophages, neutrophils) other B-cells. T-cells mount their immune response through such activities as release of cytokins (chemicals that stimulate other protective immune functions), as well as more direct action such as phagocytosis (eating) of antigens. Also called nonspecific immune response because it does not involve antibodies that are specific for a given antigen.
