    Chronic periodontal disease(PD) is one of the most frequent inflammatory diseases affecting 11.2% of the world’s population and representing a prominent public health burden. Risk factors for developing PD are cigarette smoking, diabetes, osteoporosis, and infections with periodontal pathogens(i.e. Porphyromonas gingivalis). The pathogenesis of PD is associated with an over-reactive host inflammatory response to P.gingivalis. Current literature implicates hyper-reactive neutrophils as the main immune cell type responsible for the tissue damage and the disease progression. Neutrophils have very short lifespan, controlled by the Bcl-2 family proteins, but it can be significantly prolonged during the infection. Therefore, I hypothesize that hyper-activity and prolonged survival of neutrophils induced by P.gingivalis through the increased expression of pro-survival members of the Bcl-2 family proteins is a novel, yet uncharacterized mechanism strongly contributing to the development of PD.

    La maladie parodontale chronique (PD) est l’une des maladies inflammatoires les plus fréquentes qui touche 11,2 % de la population mondiale et représente un fardeau important pour la santé publique. Les facteurs de risque de développement de la maladie sont le tabagisme, le diabète, l’ostéoporose et les infections parodontales (p. ex. Porphyromonas gingivalis). La pathogenèse de la DP est associée à une réponse inflammatoire de l’hôte surréactif à P.gingivalis. Dans la littérature actuelle, les neutrophiles hyperréactifs sont le principal type de cellules immunitaires responsables des lésions tissulaires et de la progression de la maladie. Les neutrophiles ont une durée de vie très courte, contrôlée par les protéines de la famille Bcl-2, mais elles peuvent être significativement prolongées pendant l’infection. Par conséquent, j’imagine que l’hyperactivité et la survie prolongée des neutrophiles induites par P.gingivalis par l’expression accrue des membres pro-survivaux des protéines de la famille Bcl-2 sont un mécanisme nouveau, mais non caractérisé, contribuant fortement au développement de la PD.

    Chronische Parodontalerkrankung (PD) ist eine der häufigsten entzündlichen Erkrankungen, die 11,2 % der Weltbevölkerung betreffen und eine hohe Belastung für die öffentliche Gesundheit darstellen. Risikofaktoren für die Entwicklung von PD sind Zigarettenrauchen, Diabetes, Osteoporose und Infektionen mit Parodontalpathogenen (d. h. Porphyromonas Gingivalis). Die Pathogenese von PD ist mit einer überreaktiven Wirtsentzündungsreaktion auf P.gingivalis assoziiert. Die aktuelle Literatur bezieht sich auf hyperreaktive Neutrophilen als Haupt-Immunzelltyp, der für den Gewebeschaden und den Krankheitsverlauf verantwortlich ist. Neutrophilen haben eine sehr kurze Lebensdauer, die von den Proteinen der Familie Bcl-2 kontrolliert wird, aber sie können während der Infektion erheblich verlängert werden. Daher gehe ich davon aus, dass Hyperaktivität und verlängertes Überleben von Neutrophilen, die durch P.gingivalis durch die erhöhte Expression pro-survivaler Mitglieder der Bcl-2-Familienproteine induziert werden, ein neuartiger, aber nicht charakterisierter Mechanismus ist, der stark zur Entwicklung von PD beiträgt.

    Chronische parodonttale ziekte (PD) is een van de meest voorkomende inflammatoire ziekten die 11,2 % van de wereldbevolking treffen en een prominente volksgezondheidslast vertegenwoordigen. Risicofactoren voor het ontwikkelen van PD zijn het roken van sigaretten, diabetes, osteoporose en infecties met periodontale pathogenen (d.w.z. Porphyromonas gingivalis). De pathogenese van PD wordt geassocieerd met een overreactieve gastheer ontstekingsreactie op P.gingivalis. De huidige literatuur houdt hyperreactieve neutrofielen in als belangrijkste immuunceltype dat verantwoordelijk is voor de weefselschade en de ziekteprogressie. Neutrofielen hebben een zeer korte levensduur, gecontroleerd door de Bcl-2-eiwitten, maar het kan aanzienlijk worden verlengd tijdens de infectie. Daarom stel ik voor dat hyperactiviteit en langdurige overleving van neutrofielen geïnduceerd door P.gingivalis door de verhoogde expressie van pro-overlevingsleden van de Bcl-2-familieproteïnen een nieuw, maar niet gekarakteriseerd mechanisme is dat sterk bijdraagt aan de ontwikkeling van PD.

    La malattia parodontale cronica (PD) è una delle malattie infiammatorie più frequenti che colpiscono l'11,2 % della popolazione mondiale e rappresenta un importante onere per la salute pubblica. I fattori di rischio per lo sviluppo della PD sono il fumo di sigarette, il diabete, l'osteoporosi e le infezioni con patogeni parodontali (vale a dire Porphyromonas gingivalis). La patogenesi della PD è associata a una risposta infiammatoria dell'ospite iper-reattiva a P.gingivalis. La letteratura attuale implica neutrofili iperreattivi come il principale tipo di cellule immunitarie responsabili del danno tissutale e della progressione della malattia. I neutrofili hanno una durata di vita molto breve, controllata dalle proteine della famiglia Bcl-2, ma può essere significativamente prolungata durante l'infezione. Pertanto, ipotizzo che l'iperattività e la sopravvivenza prolungata dei neutrofili indotti da P.gingivalis attraverso l'aumentata espressione dei membri pro-sopravvival delle proteine della famiglia Bcl-2 sia un meccanismo nuovo, ma non caratterizzato, che contribuisce fortemente allo sviluppo della PD.
