Knochenheilung
Knochen ist ein sehr interessantes Gewebe, da es zur Regeneration fähig ist, nachdem es eine Verletzung erlitten hat. Trotzdem kommt es auch heute noch und auch bei guter medizinischer Versorgung, bei 5-20% aller Frakturen zu einer für den Patienten unbefriedigenden verspäteten Heilung oder die Heilung bleibt sogar vollständig aus. Für diese Patienten eine sinnvolle Lösungsstrategie zu finden ist Ziel unserer Forschung.

Titel:Individual Effector/Regulator T Cell Ratios Impact Bone Regeneration
There is increasing evidence that T lymphocytes play a key role in controlling endogenous regeneration. Regeneration Using adoptive TReg transfer, bone healing was consistently improved in mice possessing an inexperienced immune system with low amounts of CD8+ TEFF. In contrast, mice with an experienced immune system (high amounts of CD8+ TEFF) showed heterogeneous bone repair with regeneration being dependent upon the individual TEFF/TReg ratio. Thus, the healing outcome can only be improved by an adoptive TReg therapy, if an unfavorable TEFF/TReg ratio can be reshaped; if the individual CD8+ TEFF percentage, which is dependent on the individual immune experience can be changed toward a favorable ratio by the TReg transfer.

Titel:Experience in the Adaptive Immunity Impacts Bone Homeostasis, Remodeling, and Healing
Bone formation is substantially reduced in aged individual owing to the experience of the adaptive immunity. Thus, immune-aging in addition to chronological aging is a potential risk factor, with an experienced immune system being recognized as more pro-inflammatory. In metaphyseal bone, immune-aging affects bone homeostasis by impacting bone formation capacity and thereby influencing mass and microstructure of bone trabeculae leading to an overall reduced mechanical competence as found in bone torsional testing. Bone formation is impacted during bone regeneration in terms of a diminished healing capacity observed in young animals who have an experienced human immune system. Considering the immune system's experience level will likely allow a more effective differentiation (stratify) and treatment (immune-modulate) of patients .
