Staphylococcus aureus inhibits contact sensitivity to oxazolone by activating suppressor B cells in mice. 1984

G Benedettini, and G De Libero, and L Mori, and M Campa

Killed Staphylococcus aureus strain Cowan I cells inhibit contact sensitivity to oxazolone in mice, when given intravenously 24-72 h before sensitization. With transfer experiments it was found that the cells responsible for the suppression are antigen-specific, nylon-adherent, resistant to antitheta serum + C, and sensitive to anti-mouse Ig serum + C. These suppressor B cells bear anti-oxazolone immunoglobulins and appear to exert their suppressive activity by preventing the contact sensitizer from reaching the specific reactive T cells.

UI MeSH Term Description Entries
D007108 Immune Tolerance The specific failure of a normally responsive individual to make an immune response to a known antigen. It results from previous contact with the antigen by an immunologically immature individual (fetus or neonate) or by an adult exposed to extreme high-dose or low-dose antigen, or by exposure to radiation, antimetabolites, antilymphocytic serum, etc. Immunosuppression (Physiology),Immunosuppressions (Physiology),Tolerance, Immune
D007111 Immunity, Cellular Manifestations of the immune response which are mediated by antigen-sensitized T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role.

D008213 Lymphocyte Activation Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D008810 Mice, Inbred C57BL One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D003877 Dermatitis, Contact A type of acute or chronic skin reaction in which sensitivity is manifested by reactivity to materials or substances coming in contact with the skin.
