In Silico Destruction of Porphyromonas gingivalis Fimbriae by Streptomyces sp. Strain GMY02 [PDF]

BIO Web of Conferences, 2023
Porphyromonas gingivalis, a keystone pathogen in chronic periodontitis, has fimbria as one of the most important virulence factors because it plays a vital role in the pathogenesis of P. gingivalis infection.

Giant honeybees (Apis dorsata) trade off defensiveness against periodic mass flight activity. [PDF]

PLoS ONE
The giant honeybee Apis dorsata (Fabricius, 1793) is an evolutionarily ancient species that builds its nests in the open. The nest consists of a single honeycomb covered with the bee curtain which are several layers of worker bees that remain almost ...

Porphyromonas gingivalis Suppresses Interferon-Gamma Signaling in Macrophages Through a Contact-Dependent, Gingipain-Mediated Mechanism. [PDF]

Microbiologyopen
This study reveals that Porphyromonas gingivalis suppresses IFN‐γ signaling by downregulating STAT1 in macrophages. Gingipain protease activity and the Type IX Secretion System are essential for this immune evasion mechanism. These findings identify a novel bacterial strategy for host immune suppression and suggest new therapeutic targets for P ...

cAMP-independent Crp homolog adds to the multi-layer regulatory network in Porphyromonas gingivalis [PDF]

Frontiers in Cellular and Infection Microbiology
IntroductionPorphyromonas gingivalis encodes three CRP/FNR superfamily proteins: HcpR, PgRsp, and CrpPg, with CrpPg similar to cAMP-sensing proteins but not classified into known families.
