Moreover, because of the different antigen
sensitivities, a therapy-limiting response from one antigen
will occur while other antigens
in the same treatment vial will remain at far-from-optimal dosages.
Immune cells that recognize IE antigens
destroyed the infected cells.
Tests to determine the amount of prostate-specific antigen
(PSA), a protein produced by the cells of the prostate gland, in the blood along with a digital rectal exam is used to help initially detect prostate cancer and is also used to monitor patients with a history of prostate cancer to see if the cancer has come back, or recurred.
The response against uninfected antigenic preparations was always above background, reducing the sensitivity of the assay (data not shown); therefore, the commercially available antigens
were used in subsequent experiments.
Suppression of cellular and humeral immunity to T-dependent antigens
by calorie restriction.
Injected vaccines place antigens
directly in the bloodstream, which becomes the site of most of the protective antibody and cellular immune response.
Based in Freiburg, Germany, DIARECT is a privately-held company that specializes in the development and manufacture of antigens
through sophisticated expression and purification systems.
A total of 1,494 small mammals of different Czech regions were screened with ELISA for hantavirus antigen
in the lungs.
To eliminate this frustrating inconsistency, the investigators primed the dendritic cells with a unique tumor antigen
from the cancer cells of each patient.
Thanks to Thomas Ksiazek for providing recombinant SNV antigen
and positive serum and to Robert Shope for his assistance.
Caspi has found that low doses of a retinal protein known as retinal S antigen
prevent the inflammatory eye disease uveitis in mice.
Western blotting procedures using unheated antigens
were performed (4).
Drawing on the idea that individuals can sometimes develop a tolerance to antigens
-- substances that cause an immune reaction -- by eating them, Czerkinsky's team fed its animals sample antigens
linked to B chains.
Although the precise function of M cells has not yet been established, recent studies indicate that they are involved in uptake, transport, processing, and possibly presentation of processing, and possibly presentation of microbial antigens
Antibodies are Y-shaped molecules that bind to specific foreign proteins, or pieces of protein, called antigens
