antigen p.The mechanism by which foreign antigens are taken into antigen-presenting cells (APCs) and broken up. Part of the antigen is then displayed (presented) on the surface of the APC next to a histocompatibility or self-antigen, activating T lymphocytes and cell-mediated immunity. T lymphocytes are unable to recognize or respond to most antigens without APC assistance.

SEE: antigen; macrophage processing; self.

daylight p.An automatic system that accepts radiographic film, inserts it into the processor, and refills the cassette without the need for a darkroom.

extended p.In mammography, an increase of the development time or developer temperature to enhance image contrast and /or lower the radiation dose to the patient.

image p.Any of the computer-aided improvements in a radiological image to highlight some of its features and /or improve its contrast or definition.

macrophage p.The mechanism by which foreign antigens are taken into the macrophage by phagocytosis and broken up. Part of the antigen is then displayed on the surface of the macrophage next to a histocompatibility or self-antigen activating T lymphocytes and the specific immune response. T lymphocytes are unable to recognize or respond to most antigens without macrophage assistance.
