Implication du système télomères/télomérase au cours de la mastocytose.

Abstract : Mastocytosis is a heterogeneous disease characterized by an accumulation of mast cells. Children and adults hold different c-Kit mutations. In a first work, we showed that only adult forms are associated with reactivation of telomerase whereas pediatric forms are not. This seems to be linked to the differential c-Kit mutations observed between adults and children and could explain why only pediatric mastocytosis spontaneously regress in comparison with adult forms. These results help to better elucidate the pathophysiology of mastocytosis. In a second work, we studied the link between the telomere length and the psychological features of adults with mastocytosis and showed that negative emotionality correlated negatively to telomere length and that telomere shortening was strongly predicted by emotion regulation deficits. We hypothesize that in psychological disorders, mast cell may represent the link between brain and periphery and induce telomere shortening. Key words:
