as an anti-infective vitamin
A in maintaining the structural and functional integrity of mucosal epithelial cells through its actions on gene expression
a) cell proliferation
b)oxidative metabolism of various tissues
c) alter cell-mediated immune functions in children as well as in pregnant women
d) Circulating T-cell numbers were found to be significantly impaired in children having iron deficiency and anemia.
e) Increased susceptibility to predominantly intracellular microbial infections and also raise concerns about the success of immunization programs among children living in communities having widely prevalent iron deficiency
function by quenching singlet oxygen and other reactive oxygen species, including free radicals.
killing of bacteria
human PMN incubated with -carotene and bacteria, the bacteria were killed efficiently and the PMN were not damaged or destroyed by the free radicals.
*T helper cell numbers were significantly increased in individuals given -carotene supplementation.
*A large body of epidemiological evidence has shown
that diets rich in carotenoids have been associated with
lower risk of developing many types of cancer
*it was shown that human natural killer cells killed significantly more tumor cells when incubated with -carotene than human cells not exposed to -caroten
