INTRODUCTION Microchimerism- beneficial or adverse effects 10 noiembrie 2015 - Timșoara, România INTRODUCTION Microchimerism- beneficial or adverse effects Real-time quantitative PCR detects and quantifies male DNA in multiple brain regions of women AD more prevalent in parous then in nulliparous Higher number of pregnancies correlates with a younger age of AD onset

Subjects and specimens 26 deceased women without neurological disease and 33 women with AD Age of death ranged from 32 to 101 Age of AD onset in those who had it ranged between 64 and 93 years, 77 median Frontal lobe, parietal lobe, temporal lobe, occipital lobe, cingulate gyrus, hippocampus, amygdala, caudate, putamen, globus pallidus, thalamus, medulla, pons, cerebellum and spinal cord

STATISTICS Association was reported as an odds ratio (OR) along with p value to indicate significance Rate ratio - RR of 0.30 could be interpreted to say that the rate of Mc detection in subjects with AD was 70% lower than the rate of Mc detection in subjects without neurological disease

RESULTS Mc Prevalence and Concentration According to Brain Regions Prevalence and Concentration of Male Mc in Human Brain: Women without Neurologic Disease or with AD Prevalence and Concentration of Male Mc in Brain Regions Affected by AD

The origin of male Mc in female brain is: from pregnancy with a male fetus from an abortion or a miscarriage from a recognized or vanished male twin, an older male sibling or through non-irradiated blood transfusion
