4 Pharmacology and Biochemistry
4.1 MeSH Pharmacological Classification

Adjuvants, Immunologic

Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity. (See all compounds classified as Adjuvants, Immunologic.)


Coloring Agents

Chemicals and substances that impart color including soluble dyes and insoluble pigments. They are used in INKS; PAINTS; and as INDICATORS AND REAGENTS. (See all compounds classified as Coloring Agents.)


Food Coloring Agents

Natural or synthetic dyes used as coloring agents in processed foods. (See all compounds classified as Food Coloring Agents.)
