Nasal or Oral Immunization with GroEL Attenuates Porphyromonas gingivalis-Induced Atherosclerosis

Nasal immunization with Porphyromonas gingivalis outer membrane protein decreases P. gingivalis-induced atherosclerosis and inflammation in spontaneously hyperlipidemic mice.

Porphyromonas gingivalis has been shown to accelerate atherosclerotic lesion development in hyperlipidemic animals. We assessed the potential of a nasal vaccine against P. gingivalis infection for the prevention of atherosclerosis. Apolipoprotein E-deficient spontaneously hyperlipidemic (Apoe(shl)) mice were nasally immunized with the 40-kDa outer membrane protein (OMP) of P. gingivalis plus ch...

C . A . Genco - accelerated Atherosclerosis Porphyromonas gingivalis

Oral immunization with recombinant Streptococcus gordonii expressing porphyromonas gingivalis FimA domains.

Porphyromonas gingivalis, a gram-negative anaerobe, is implicated in the etiology of adult periodontitis. P. gingivalis fimbriae are one of several critical surface virulence factors involved in both bacterial adherence and inflammation. P. gingivalis fimbrillin (FimA), the major subunit protein of fimbriae, is considered an important antigen for vaccine development against P. gingivalis-associ...

Immunization with Porphyromonas gingivalis capsular polysaccharide prevents P. gingivalis-elicited oral bone loss in a murine model.

The capsular polysaccharide (CPS) of the periodontal pathogen Porphyromonas gingivalis is an important virulence factor for this organism. We purified P. gingivalis CPS, immunized mice with this antigen, and assessed the vaccine potential of P. gingivalis CPS by using the murine oral challenge model. Animals immunized with P. gingivalis CPS developed elevated levels of immunoglobulin M (IgM) an...

Antibody Titer Against Porphyromonas Gingivalis in Rats with Experimentally Induced Periodontitis

Background and Aim: This study aimed to assess the antibody titer against Porphyromonas gingivalis (P. gingivalis) in rats with experimentally induced periodontitis. Materials and Methods: Thirty-three Surrey rats were randomly divided into three groups (n=11). Group 1 was vaccinated with formalin-killed whole cell (FKWC) P. gingivalis with incomplete Freund's adjuvant as vaccine carrier and o...
