This thesis investigated the influence of mast cells (HMC-1) on proliferation and survival of irradiated keratinocytes (HaCaT cell line) as well as its effects on the expression of key genes of apoptosis and cell adhesion. Irradiating cells up to 5 Gy, we found that the addition of mast cells significantly increased HaCaT cell proliferation and survival, indicating that mast cells can improve cellular repair and radio resistance in irradiated keratinocytes. Furthermore, it could be demonstrated on mRNA and protein level, that mast cells modulate relevant apoptotic signaling proteins and adhesion molecules.
These effects of mast cells may be a basis for new therapeutic approaches in the treatment of the cutaneous radiation syndrome.
