Relative avidities of human immunoglobulin G antibodies for streptococcal pyrogenic exotoxins A and B.
نویسندگان
چکیده
In this pilot study, we investigated the relative avidities for streptococcal pyrogenic exotoxin A (SPE-A) and SPE-B of antibodies in sera from patients with fatal streptococcal toxic shock-like syndrome and from healthy individuals and in intravenous immunoglobulin (IVIG) preparations. We observed a great variation in the relative avidities of patient, control, and IVIG immunoglobulin G (IgG) (values estimated to be between 10(-7) and 10(-11) M), with mean values for patient IgG about 10-fold lower than those of control IgG.

Group A streptococcal pyrogenic exotoxin (scarlet fever toxin) type A and blastogen A are the same protein.
Group A streptococcal pyrogenic exotoxins A, B, and C (also known as scarlet fever toxins and erythrogenic toxins) were evaluated for relatedness to another streptococcus-derived lymphocyte mitogen, blastogen A. Streptococcal pyrogenic exotoxin A and blastogen A were immunologically cross-reactive and shared the same molecular weight, N-terminal amino acid sequence, and capacity to stimulate ra...

Group A streptococcal pyrogenic exotoxins types A, B, and C and staphylococcal pyrogenic exotoxin were shown to be potent nonspecific T-lymphocyte mitogens. Adherent cell populations did not significantly affect the nonspecific mitogenicity.
متن کاملCloning of the gene, speB, for streptococcal pyrogenic exotoxin type B in Escherichia coli.
The structural gene encoding streptococcal pyrogenic exotoxin type B, designated speB, was cloned in Escherichia coli and localized onto a 4.5-kilobase BamHI-BglII DNA fragment. Streptococcal pyrogenic exotoxin type B, partially purified from E. coli clones, was immunologically related to streptococcus-derived toxin. Also, toxin derived from either E. coli or Streptococcus pyogenes had similar ...
متن کاملGanglioside and monosaccharide inhibition of nonspecific lymphocyte mitogenicity by group A streptococcal pyrogenic exotoxins.
Group A streptococcal pyrogenic exotoxins (SPE) types A, B, and C are potent nonspecific lymphocyte mitogens. The mitogenicity of these exotoxins was inhibited by gangliosides and sialic acid, whereas concanavalin A was unaffected. The capacity of both concanavalin A and SPE-A to stimulate lymphocytes was suppressed by alpha-methyl-D-mannopyranoside. Galactose reduced the activity of SPE-C. The...
متن کاملThe superantigenic activity of streptococcal pyrogenic exotoxin B is independent of the protease activity.
The nature of the mitogenic activity of pyrogenic streptococcal exotoxin B, also known as streptococcal cysteine protease, has been debated in the literature. Streptococcal exotoxin B has been shown to cleave interleukin-1beta precursor and create biologically active interleukin-1beta, a major cytokine mediating inflammation and shock. This activity could mimic the mitogenicity and cytokine rel...
