Cytokines and Periodontal Diseases. In inflammatory processes (Periodontal Disease), the over-expression of cytokines (IL-1; TNF) is extremely detrimental for the host. Our approach to reduce deleterious effects associated with the over-expression of these cytokines consisted in identifying molecular factors controlling cytokine gene expression in inflammatory processes and particularly in gingivitis and in periodontitis. Recently, we have cloned a novel transcription factor capable of repressing significantly TNF gene expression.
Wound Healing and Periodontal Regeneration. My group has been interested in the identification and characterization of cells and extracellular matrix macromolecules involved in periodontal wound healing. Particularly, our effort has focused on the identification of critical factors involved in driving periodontal wounds into the regeneration of periodontal structures after periodontal diseases.
