Flow cytometry analysis of natural killer (NK) cells. Bar graphs of statistical analysis of NK cell present in patient samples (a) and functionality as measured by Interferon gamma (INFg) from patients with Euthyroid Hashimoto Thyroiditis (EHT) (n = 8) and Graves disease (GD) (n = 8) (b). Flow cytometry raw data sample of NK cells in EHT or GD and bar graph statistical quantification based on production of cytotoxic enzymes: Granulysin, Granzyme B and Perforin (c). Statistical significance was determined by using t-test: two samples assuming unequal variance. a b depicts the difference (P < 0.05) between the groups
