antidiuretic hormone

DEFINITION:

See vasopressin.

arginine vasopressin

DEFINITION:

Vasopressin containing arginine, as that from most mammals, including man.

AVP

DEFINITION:

Arginine vasopressin.

cyclic AMP

DEFINITION:

Cyclic adenosine monophosphate.

immunofluorescence

DEFINITION:

The labeling of antigens or antibodies with fluorescent dyes
for the purpose of demonstrating the presence of corresponding antibodies or antigens in a
tissue preparation or smear.

cAMP

DEFINITION:

Cyclic AMP (cyclic adenosine monophosphate).

antidiuretic

DEFINITION:

1. Suppressing the rate of urine formation.

2. An agent that suppresses urine formation.

cultured

DEFINITION:

Having induced the propagation of microorganisms or living tissue cells in media conducive to their growth.

epithelial cells

DEFINITION:

Cells that cover the surface of the body and line its cavities.

transport

DEFINITION:

The movement of materials in biological systems, particularly into and out of cells and across epithelial layers.

aquaporin-2

DEFINITION:

Also called WCH-CD, this water channel makes the principal cells of the inner medullary collecting duct in the kidneys more permeable to water. Lack of functional aquaporin-2 gene leads to a rare form of nephrogenic diabetes insipidus.

AQP2

DEFINITION:

Aquaporin-2.

vesicles

DEFINITION:

1. Small bladders or sacs containing liquid.
2. Small circumscribed epidermal elevations, usually containing a clear fluid.

subsequent

DEFINITION:

Following after; succeeding.

fusion

DEFINITION:

1. The act, process, or result of melting.

2. The merging or coherence of adjacent parts or bodies.

3. The coordination of the separate images of the same object in the two eyes into one.

4. The operative formation of an ankylosis or arthrodesis.

plasma membrane

DEFINITION:

The structure enveloping a cell, enclosing the cytoplasm, and forming a selective permeability barrier; it consists of lipids, proteins, and some carbohydrates, the lipids thought to form a bilayer in which integral proteins are embedded to varying degrees.

AVP

DEFINITION:

Arginine vasopressin.

AVP

DEFINITION:

Arginine vasopressin.

exocytosis

DEFINITION:

1. The discharge from a cell of particles that are too large to diffuse through the wall; the opposite of endocytosis.

2. The aggregation of migrating leukocytes in the epidermis as part of the inflammatory response.

confined

DEFINITION:

1. Held within a location; also, imprisoned.

2. Kept within limits.

analysis

DEFINITION:

1. Separation into component parts or elements; the act of determining the component parts of a substance.

2. Psychoanalysis.
