Osteoimmunology And The Reconstruction Of Host Immunological Status In Treponemal Infection: Effect Of Activated Immune Cells By Oral Pathogens And Treponema Pallidum On Osteoclastogenesis., Michayla Gatsos

College of Arts & Sciences Senior Honors Theses

Syphilitic infection caused by bacterium Treponema pallidum pallidum (Tp) offers an excellent model to study the long-lasting interplay between the immune and skeletal systems and could be used to reconstruct host immunological status. We propose that a hyper-inflammatory phenotype developed during acquired syphilis will have a systemic impact on most bone microenvironments involving inflammatory processes, such as the one developed in periodontal disease (PD). Using osteoimmunological in vitro protocols, we explore whether immune activation by Tp antigens and PD pathogens can impact osteoclastogenesis (OCG), ultimately helping to understand the bone alterations caused by systemic inflammatory processes in skeletal material. We …
