The role of resveratrol (can be extracted from grape, veratrum album which commonly known as the False Helleborine, also known as White Hellebore, European White Hellebore, White Veratrum) and curcumin (extracted from Turmeric, also known as yellow ginger) is well documented in cancer, inflammation, diabetes and various other diseases. However, their immuinnosuppressive action on T cells, B cells and macrophages is not well documented. In the present study, we have ascertained the effect of resveratrol and curcumin on T and B cells and macrophages. The most striking findings were that both resveratrol and curcumin suppressed the activity of T and B cells and macrophages, as evidenced by significant inhibition in proliferation, antibody production and lymphokine secretion. Interestingly, curcumin imparted immunosuppression by mainly down-regulating the expression of CD28 and CD80 and up-regulating CTLA-4. Resveratrol also functioned by decreasing the expression of CD28 and CD80, as well as by augmenting the production of interleukin (IL)-10.
