The Role of CD3 and CD8 in Preterm Preeclamptic women by using Immunohistochemical technique

Preterm birth (PTB) and PE are the two major causes of perinatal mortality, morbidity, and long-range neurological disability. PTB defined as delivery before 37 weeks gestation, has become an epidemic in developed countries, Indeed PTB and PE are leading causes of maternal and neonatal death worldwide. The immunohistochemical study show: - The staining intensity for PE immunohistochemical showed the greatest (+2) intensity was recorded at 52% for anti-CD3 lymphocyte biomarker. Also, followed by 28% of (+1) Intensity was comparable biomarkers. (12%) of +3 and 8% for 0 intensity when compared with Tonsil control positive and placental tissue control negative. On the other hand, the staining intensity for PE immunohistochemical shows the greatest frequency of (0) intensity was recorded for anti-CD8 cytotoxic T-cell biomarker with 52 % then +1 (28%) and 20% for +2 when compared with skin control positive and negative.
