Although it is well established that the streptococcal M protein extends from the surface of the streptococcal cell as an alpha-helical coiled-coil dimer with structural homology to myosin and other alpha-helical coiled-coil molecules (16, 17), no studies have investigated the role of M protein in an animal model of valvular heart disease, the most serious sequela of RF.

Läs hela texten Se hela listan på verywellhealth.com The conformation and molecular dimensions of purified type 6 streptococcal M proteins establish the close structural relationship of these molecules to tropomyosin. Ultracentrifuge studies reveal that the M molecules exist as stable dimers; circular dichroism spectra indicate that the molecules contain about 70% alpha helix; and fiber x-ray diffraction diagrams show the characteristic After serologic confirmation as GAS, isolates were emm genotyped (emm encodes the M protein) at the Streptococcal Research Laboratory of the Centers for Disease Control and Prevention (Atlanta, GA) . Concordance between serologic and genotypic results has been demonstrated [ 26 ].

Specific regions of M protein also serve as shared antigens … The M protein gene (emm) encodes the cell surface M virulence protein responsible for at least 100 Streptococcus pyogenes M serotypes. emm typing is based on sequence analysis of the portion of the emm gene that dictates the M serotype.

This response is significantly increased in the presence of neutrophil-derived heparin-binding protein (HBP), which costimulates monocytes by interacting with CD11/CD18. Keywords:Rheumatic fever, rheumatic heart disease, Streptococcus pyogenes, T cell response, autoimmunity, molecular mimicry, M protein, heart proteins. Abstract: Molecular mimicry between streptococcal and human proteins has been proposed as the triggering factor leading to autoimmunity in rheumatic fever (RF) and rheumatic heart disease (RHD).
