Journal ArticleDOI
Anchoring and length regulation of Porphyromonas gingivalis Mfa1 fimbriae by the downstream gene product Mfa2.
Yoshiaki Hasegawa,Jun Iwami,Keiko Sato,Yoonsuk Park,Kiyoshi Nishikawa,Tatsuo Atsumi,Keiichi Moriguchi,Yukitaka Murakami,Richard J. Lamont,Hiroshi Nakamura,Norikazu Ohno,Fuminobu Yoshimura +11 more
TL;DR: Co-immunoprecipitation demonstrated that Mfa2 and Mfa1 are associated with each other in whole P. gingivalis cells, and immunogold microscopy confirmed that MFA2 was located on the cell surface and likely associated with Mfa 1 fimbriae.
Journal ArticleDOI
Analysis of major virulence factors in Porphyromonas gingivalis under various culture temperatures using specific antibodies
Yukitaka Murakami,Takashi Masuda,Masashi Imai,Jun Iwami,Hiroshi Nakamura,Toshihide Noguchi,Fuminobu Yoshimura +6 more
TL;DR: The tendency for expression of major virulence factors to decrease at higher temperatures may enable P. gingivalis to survive under hostile conditions.
Journal ArticleDOI
Energy filtering transmission electron microscopy immunocytochemistry and antigen retrieval of surface layer proteins from Tannerella forsythensis using microwave or autoclave heating with citraconic anhydride
Keiichi Moriguchi,Y Mitamura,Jun Iwami,Yoshiaki Hasegawa,Naoya Higuchi,Yukitaka Murakami,Hatsuhiko Maeda,Fuminobu Yoshimura,Hiroshi Nakamura,Norikazu Ohno +9 more
TL;DR: The three-window method for electron spectroscopic images of nitrogen by the EFTEM reflected the presence of moieties demonstrated by the DAB reaction with horseradish peroxidase-conjugated secondary antibodies instead of immunogold particles, and the mapping patterns of net nitrogen were restricted to the outermost cell surface.
Journal ArticleDOI
Immunocytochemical approach for surface layer proteins of freeze-substituted Tannerella forsythensis by energy-filtering transmission electron microscopy.
Keiichi Moriguchi,Takamichi Jogahara,Takayuki Kurihara,Jun Iwami,Naoya Higuchi,Yukitaka Murakami,Hatsuhiko Maeda,Fuminobu Yoshimura,Hiroshi Nakamura,Norikazu Ohno +9 more
TL;DR: The relation between high molecular weight proteins and S-layer in energy-filtering transmission electron microscopy (EF-TEM) to visualize 3,3'-diaminobenzidene, tetrahydrochloride (DAB) reaction was examined and mapping patterns of net N element were restricted to the outermost cell surface.
