Autophagy promotes phagocytosis and clearance of Treponema pallidum via the NLRP3 inflammasome in macrophages

Journal of the European Academy of Dermatology and Venereology, 2020
Elucidating the mechanism of the macrophage phagocytic response will improve our knowledge of host defence against Treponema pallidum.

Treponema, Iron and Neurodegeneration

Current Alzheimer Research, 2018
Spirochetes are suspected to be linked to the genesis of neurological diseases, including neurosyphillis or neurodegeneration (ND). Impaired iron homeostasis has been implicated in loss of function in several enzymes requiring iron as a cofactor, formation of toxic oxidative species, inflammation and elevated production of beta-amyloid proteins. This

A Lipopolysaccharide Antigen of the Treponema

Nature, 1958
IMMUNOCHEMICAL studies carried out by D'Alessandro et al. 1 on a non-pathogenic, culturable treponeme, the so-called Reiter treponeme, revealed the presence of four antigenic components: (1) a thermolabile protein; (2) a specific, thermostable antigen with polysaccharide characteristics; (3) a lipoid, corresponding to the ubiquitous lipidic antigen ...

Identification of Glycosylated Protein Antigens of Treponema pallidum and Treponema phagedenis

Zentralblatt für Bakteriologie, Mikrobiologie und Hygiene. Series A: Medical Microbiology, Infectious Diseases, Virology, Parasitology, 1985
Comparison of autoradiographies of intrinsically [35S] methionine and [14C] glucosamine labeled Treponema pallidum (Nichols strain) after sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) revealed four glycosylated proteins with molecular weights 30,500, 33,000, 35,000, and 59,000.

Albumin requirement of Treponema denticola and Treponema vincentii

Canadian Journal of Microbiology, 1983
Treponema denticola and Treponema vincentii were found to require albumin, oleic acid, and thiamine pyrophosphate (TPP) for growth. Previous studies indicated that commercial human alpha globulin, which is 50% albumin, was the only serum fraction that supported growth of these two oral treponemes.

Fatty acid requirement of Treponema denticola and Treponema vincentii

Canadian Journal of Microbiology, 1982
Treponema denticola and Treponema vincentii were cultured in a medium supplemented with either 0.2 or 0.4% (w/v) alpha globulin in place of serum. The active factor(s) in alpha globulin was stable at pH 7.0 to autoclaving and was nondialyzable. Extraction of lipids from alpha globulin showed that both protein and lipid, supplied by the alpha globulin,

The Genus Treponema

1992
Treponemes are helically coiled bacteria that are found in man and animals. Some of these host-associated organisms are pathogens, while many others can be found as part of the normal flora. They can be found in the oral cavity and intestinal tract and on the genitalia of man (Bowden and Hardie, 1971; Hanson and Cannafax, 1964; Rosebury, 1962).

THE ULTRASTRUCTURE OF CULTIVABLE TREPONEMES.

Acta Pathologica Microbiologica Scandinavica Section B Microbiology and Immunology, 1974
Treponema phagedenis, Treponema vincentii, and Treponema refringens were studied in the electron microscope by means of negative staining and sectioning techniques. The length and width of the cells were within the same limits for all three strains examined.
