Plants that are rich in vitamin A, vitamin E, vitamin D, vitamin C, and vitamin B6 have suppressed anti-dsDNA autoantibody production, Th17 cells, interleukin-17A (IL-17A)-producing T cells, lipid peroxidation, active inflammation, and IL-6 secretion and increased Treg percentages in CD4+ T cells in patients with SLE [28, 122]. This evidence concerns the gene CD4 and systemic lupus erythematosus.
