The Department of Biology at the College of Science, University of Mosul, discussed a Master’s thesis on Sunday, 28 June 2026, entitled:

“Evaluation of Lymphocyte and Macrophage Function in Individuals with Vitamin D Deficiency in Nineveh Province”

The thesis was presented by Amira Ibrahim Hussein, a Master’s student in Microbiology, in the presence of a number of faculty members from the College.

The research investigated the impact of vitamin D deficiency on selected immunological and hematological parameters by measuring the levels of the immune cytokines IL-10, IL-12, and TNF-α, in addition to evaluating lymphocyte and macrophage functions and several hematological and clinical variables among the study participants.

The study aimed to determine the effect of vitamin D deficiency on immune system efficiency, examine its role in regulating the immune response, and identify the relationship between vitamin D levels and various demographic, clinical, and hematological factors.

The findings revealed significant alterations, including elevated levels of the anti-inflammatory cytokine IL-10 and reduced levels of the pro-inflammatory cytokines IL-12 and TNF-α compared with the control group. The study also demonstrated significant associations between vitamin D levels and several immunological and hematological indicators. Furthermore, factors such as sunlight exposure, sleeping hours, age, gender, and certain clinical symptoms were found to influence both vitamin D status and immune responses.

The examination committee was chaired by Prof. Dr. Anmar Ahmed Dawood Suleiman, with membership of:

• Assist. Prof. Dr. Duha Jassim Mohammed Yaseen
• Lect. Dr. Eman Mahmoud Khudair Ahmed

The thesis was supervised by Prof. Dr. Mahmoud Abduljabbar Hussein, who also served as a member of the examination committee.

The committee commended the scientific quality of the thesis and highlighted its significance in demonstrating the vital role of vitamin D in maintaining immune homeostasis and regulating immune cell functions.

The College of Science extends its sincere congratulations to the researcher and wishes all its students continued excellence and success in their academic careers.
