The National Library of Medicine (NLM), on the campus of the National Institutes of Health in Bethesda, Maryland, is the world's largest medical library. The Library collects materials and provides information and research services in all areas of biomedicine and health care.
1) A system of organs and tissues that process and transport immune cells and lymph.
2) The tissues and organs that produce, store, and carry white blood cells that fight infections and other diseases. This system includes the bone marrow, spleen, thymus, lymph nodes, and lymphatic vessels (a network of thin tubes that carry lymph and white blood cells). Lymphatic vessels branch, like blood vessels, into all the tissues of the body.

1) A theoretical representative nucleotide or amino acid sequence in which each nucleotide or amino acid is the one which occurs most frequently at that site in the different sequences which occur in nature. The phrase also refers to an actual sequence which approximates the theoretical consensus. A known conserved sequence set is represented by a consensus sequence. Commonly observed supersecondary protein structures (amino acid motifs) are often formed by conserved sequences.
2) A sequence pattern derived from the alignment of multiple sequences that represents the nucleotide or amino acid most likely to occur at each position in a sequence.

1) A tripeptide with many roles in cells. It conjugates to drugs to make them more soluble for excretion, is a cofactor for some enzymes, is involved in protein disulfide bond rearrangement and reduces peroxides.
2) Tripeptide composed of gamma-glutamate, cysteine, and glycine; an important endogenous reducing agent involved in oxidative respiration and free radical scavenging.
3) The peptide gamma-glutamylcysteinylglycine.
4) A tripeptide present in most cells comprised of three amino acids (cysteine, glutamic acid, and glycine) acting as an antioxidant, enhancing free radical scavenging, a detoxifying agent, binding to and transforming chemicals into excretable forms, a co-factor for some enzymes, and to boost the immune system.(NCI)

1) A tumor made up of nerve cells and nerve fibers. (Dorland, 27th ed)
2) This is a tumor that grows from a nerve or is composed of nerve cells and nerve fibers. - 2002

1) A tumor that has spread from its original (primary) site of growth to another site, close to or distant from the primary site. Metastasis is characteristic of advanced malignancies, but in rare instances can be seen in neoplasms lacking malignant morphology. -- 2004
2) The spread of cancer from one part of the body to another. A tumor formed by cells that have spread is called a "metastatic tumor" or a "metastasis." The metastatic tumor contains cells that are like those in the original (primary) tumor. The plural form of metastasis is metastases.
Industry:Health care
1) A type of biological response modifier (a substance that can improve the body's natural response to disease). It slows the rate of growth and division of cancer cells, causing them to become sluggish and die.
2) A biological response modifier (a substance that can improve the body's natural response to infections and other diseases). Interferons interfere with the division of cancer cells and can slow tumor growth. There are several types of interferons, including interferon-alpha, -beta, and -gamma. The body normally produces these substances. They are also made in the laboratory to treat cancer and other diseases.
Industry:Health care
1) A type of protein made by certain white blood cells in response to a foreign substance (antigen). Each antibody can bind to only a specific antigen. The purpose of this binding is to help destroy the antigen. Antibodies can work in several ways, depending on the nature of the antigen. Some antibodies destroy antigens directly. Others make it easier for white blood cells to destroy the antigen.
2) An antibody is a protein component of the immune system that circulates in the blood, recognizes foreign substances like bacteria and viruses, and neutralizes them. After exposure to a foreign substance, called an antigen, antibodies continue to circulate in the blood, providing protection against future exposures to that antigen.
Industry:Health care
1) A type of white blood cell.
2) A large white blood cell with finely granulated chromatin dispersed throughout the nucleus that is formed in the bone marrow, enters the blood, and migrates into the connective tissue where it differentiates into a macrophage.
Industry:Health care
1) A type of white blood cell. Lymphocytes have a number of roles in the immune system, including the production of antibodies and other substances that fight infection and diseases.
2) A lymphocyte is a type of white blood cell that is part of the immune system. There are two main types of lymphocytes: B cells and T cells. The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins. The T cells destroy the body's own cells that have themselves been taken over by viruses or become cancerous.
