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 …
In Vitro Immune Activation By Treponema Pallidum And The Effect On Osteoclastogenesis: First Experimental Step Towards An Integration Between Osteoimmunology And Paleopathology., Emily Ann Rich
College of Arts & Sciences Senior Honors Theses
The presence of pathogens in the human body influences the expression of pro-inflammatory cytokines by activated immune cells. These cytokines, and other factors, regulate osteoclastogenesis and osteoclast activity. Through experimental osteoimmunology, interactions between the inflammatory response and bone cell physiology may provide insight into how immune processes can be translated into the lesions or abnormalities observed in the osteological record. In this research, our objective was to determine if the cytokines produced by activated immune cells increase osteoclastogenesis and osteoclast activity. To evaluate this hypothesis, we used two main protocols, one for immune activation and one for osteoclastogenesis, that utilized …
