In vitro Effects of L-Ascorbic Acid and Acrylamide on Lymphocyte Proliferation in Young and Aged Mice

  • Published : 2010.03.31


This study examined the effects of Acrylamide (ACR) and L-ascorbic acid (AsA) on the proliferation of splenocytes and the mitogen-stimulated lymphocyte proliferation in young (8 weeks) and aged (82 weeks) C57BL/6male mice in vitro. AsA increased splenocyte proliferation in both groups; however, this effect was higher in old mice, while the proliferation of lymphocyte was decreased except for treatment at $1\;{\mu}g/mL$ low concentration in both mice. In addition, ACR treatment resulted in decreased LPS-induced B lymphocyte proliferation and ConA-induced T lymphocyte proliferation in both groups. However, AsA increased LPS/ConA-induced lymphocyte proliferation in young groups and had no effects in old mice except at $0.5\;{\mu}g/mL$ Thus, the present data indicate that there is no difference effect of ACR and AsA on lymphocyte proliferation, whereas the effect of AsA on mitogen-induced cell proliferation was reduced in old mice. Overall, our results suggest that various immunomodulators have differing effects of lymphocytic proliferation on young versus aged mice.
