Imunitní odpověď jednotlivých subpopulací dendritických buněk na probiotický kmen E. coli O83:K24:H31

Gorelová, Miroslava

Allergy, as one of the worldwide most frequent pathologies, belongs to illnesses with constantly growing incidence among young children. Identification of prognostic markers pointing to increased risk of allergy development, allows introduction of early preventive measures. Probiotic supplementation could be one the preventive measure. It has been shown that introduction of selected probiotic strains or mixtures can prevent development of allergy. In this diploma thesis, the capacity of probiotic strain Escherichia coli O83:K24:H31 (E. coli O83) to support maturation of dendritic cells and polarization of immune responses was tested. Introduction of this probiotic vaccine called Colinfant Newborn appears to be suitable preventive measure, lowering allergy incidence in children with predisposition to development of allergy. The capacity of E. coli O83 to support maturation of the two main subpopulations of dendritic cells (myeloid dendritic cells - mDC and plasmacytoid dendritic cells - pDC) in cord blood of newborns of healthy mothers (children with relatively low risk for allergy development) and allergic mothers (children with relatively high risk for allergy development) was measured by flow cytometry. The presence of cytokines and transcription factors characteristic for particular...
