Conclusion
HSV-1 seropositive individuals showed elevated dim CD56 NK cells and CD56+ T-cells, consistent with lymphocyte activities during viral activation. CD16 expression on CD56+ T-cells suggests their involvement in viral defence, emphasizing the need for further investigation into immune responses against HSV-1.
Methods
This study employed a cross-sectional research design to examine the levels of CD56+ T-cells and CD16+ among individuals seropositive for herpes simplex virus type 1 (HSV-1) in Taif city. A total of 112 participants were enrolled, with HSV-1 serostatus determined via ELISA, and cellular evaluation conducted using flow cytometry. The study was performed between January 2023 to July 2023.
Results
Our study found 36% HSV-1 seropositivity, contrasting with higher rates in Saudi Arabia. No significant age or gender differences were observed. HSV-1 seropositive individuals showed elevated dim CD56 NK cells and CD56+ T-cells, aligning with prior research on lymphocyte infiltration during HSV-1 activation. Further investigation is warranted for CD56- T-cells and bright NK cells.
