Percentage fatty acid composition of plasma membrane phospholipids of Treg cells purified from the mice spleen

Fatty Acids (% of Total)	Cells from Mice Fed Standard Diet	Cells from Mice Fed DHA Diet
C16:0	1.99 ± 0.31	2.16 ± 0.39
C16:1	27.01 ± 0.37	27.37 ± 0.20
C18:0	18.79 ± 0.25	18.31 ± 0.67
C18:1	13.15 ± 0.56	12.78 ± 0.75
C18:2n-6	11.12 ± 0.75	10.19 ± 0.11
C20:4n-6 (AA)	25.67 ± 0.98	13.12 ± 0.28*
C20:5n-3 (EPA)	0.41 ± 0.05	6.09 ± 0.15*
C22:6n-3 (DHA)	1.77 ± 0.06	9.99 ± 0.41*

The cells were purified from the spleen of mice fed a standard diet or DHA diet for 6 weeks. Values are mean ± SEM, n = 10 mice per group of diet. *P < 0.01, significant differences between DHA diet group and standard diet group. The distribution of the percentage of the fatty acid composition was statistically identical in Treg and Teff cells.
