Diabetes is acknowledged by a disease in which the ability of the body to produce or respond to the hormone insulin is impaired, leading to abnormal metabolism of carbohydrates and elevated levels of glucose in the blood. The study will be done by testing blood of 12 individuals by collecting blood samples from them and test natural killer cells in the diabetic patients and healthy people. The aim of this study is determining the relation between natural killer cells and diabetes and its role in control group, diabetic patients and complicated diabetic patients and its relation to infection. Lastly, results shown that natural killer cells are less in diabetic patients than normal people. This decrease in the natural killer cells makes diabetic patients susceptible to infections more than normal ones.enجامعة أكتوبر للعلوم الحديثة والآدابOctober University for Modern Sciences and ArtsUniversity for Modern Sciences and ArtsMSA UniversityType 2 DiabetesNatural killer (NK) cellsFlow cytometerinfectionCD3, CD16, and CD56.Other
