bacterial antigen

Before lunchtime, the lab had its answer: the lizard blood showed no significant reactivity to any viral or bacterial antigen.

These antigen-antibody complexes are thought to be caused by excessive exposure to bacterial antigens (especially peptidoglycans).

Globulins - increased due to shunting of bacterial antigens away from the liver to lymphoid tissue.

Agglutination is commonly used as a method of identifying specific bacterial antigens, and in turn, the identity of such bacteria.

Bacterial antigens stimulate white blood cells to release MIF into the blood stream.

In response to bacterial antigens, Paneth cells release their secretory granules into the lumen of intestinal crypts.

Their failure to include suitable controls with other small intestinal disorders or to perform assays for other bacterial antigens, however, makes interpretation of their results difficult.

Odontoblasts, (the cells that form dentin) have cellular processes that extend into dentinal tubules and are the first to encounter the caries bacterial antigens.

The molecular mimicry hypothesis is similar, however it suggests that cross reactivity between some bacterial antigens and self peptide can break tolerance and lead to autoimmunity.

She is most famous for her serological classification of beta-hemolytic streptococcal bacteria, which is based on the carbohydrate composition of bacterial antigens found on their cell walls.

Synovial fluid cultures are negative, suggesting that reactive arthritis is caused either by an over-stimulated autoimmune response or by bacterial antigens which have somehow become deposited in the joints.

SP-D increases bacterial antigen presentation by dendritic cells whereas SP-A blocs differentation of the immature dendritic cells.

When exposed to bacteria or bacterial antigens, Paneth cells secrete some of these compounds into the lumen of the intestinal gland, thereby contributing to maintenance of the gastrointestinal barrier.

During a Streptococcus infection, mature antigen presenting cells such as B cells present the bacterial antigen to CD4-T cells which differentiate into helper T cells.

Chowdhry, IA., Kowal, C, Hardin, J., Zhou, Z., and Diamond B. Autoantibodies that bind glomeruli: cross-reactivity with bacterial antigen.

Assays for detection of bacterial antigens or evidence by molecular biology techniques are important for the diagnostic evaluation of HIV-infected children in whom unusual pathogens might be involved or difficult to identify or culture by standard techniques.

Oral tolerance, the specific suppression of cellular and/or humoral immune reactivity to an antigen by prior administration of the antigen by the oral route, probably evolved to prevent hypersensitivity reactions to food proteins and bacterial antigens present in the mucosal flora.

In addition, chronic arthritis secondary to S. flexneri infection, called Reiter syndrome, may be caused by a bacterial antigen; the occurrence of this syndrome is strongly linked to HLA-B27 genotype, but the immunologic basis of this reaction is not understood.

Dellabona P, Casorati G, Friedli B, Angman L, Sallusto F, Tunnacliffe A, Roosnek E, Lanzavecchia A. In vivo persistence of expanded clones specific for bacterial antigens within the human T cell receptor a/b CD4-8- subset.

He returned to England in 1938 to take up a position as Reader of Biochemistry at the Lister Institute, continuing to work on bacterial antigens before the outbreak of World War II forced him to stop his research due to the perceived risk of large bacterial cultures possibly being exposed to the atmosphere by bombing.
