Evaluation of intracellular cytokines in covid-19 vaccinated individuals
Coronavirus disease 2019 (COVID-19) has infected over 500 million people and has caused 6 million deaths worldwide. Many studies have reported that the “cytokine storm” is associated with poor outcomes and severe complications in this infection. COVID-19 vaccine should be suppressed cytokine stor...

| description |
Coronavirus disease 2019 (COVID-19) has infected over 500 million people
and has caused 6 million deaths worldwide. Many studies have reported that the
“cytokine storm” is associated with poor outcomes and severe complications in this
infection. COVID-19 vaccine should be suppressed cytokine storm at least hamper its
deleterious impact by stimulation of the immune system. This study is important to
provide preliminary data on the intracellular cytokines among vaccinated individual
for the future study related to COVID-19 vaccination. The study aimed to determine
the level of IL-2, IL-4, IFN-γ and TNF-α in COVID-19 vaccinated individuals as well
as expression of surface antigens CD3/CD4, CD3/CD8. In this study, peripheral
mononuclear blood cell (PBMC) was stimulated using PepTivator SAR-CoV-2 Pot S1
peptide. Stimulated PBMC were stained, and cells were acquired by a flow cytometer.
The results showed that IL-2, IL-4, IFN-γ and TNF-α were secreted by CD4+ and CD8+
in all individuals following vaccination. In this study, these intracellular cytokines
were consistently produced after second dose and booster vaccination. In conclusion,
the sample size in this study is small and does not represent the entire population. As
a result, more research is needed to determine the level of IL-2, IL-4, IFN-γ and TNF-
α expression on CD4+ or CD8+ T cells after vaccination and their role in the prevention
of cytokine storm in COVID-19 infections and protection against infection. |
