We investigate an analysis of channel estimation using an interpolation technique in orthogonal frequency division multiplexing systems. Then a criterion for the adaptive interval of pilot subcarriers is derived. The mean-square error (mse) of comb-type estimators is dominated by the length of channel delay and the interval of pilot subcarriers. Analysis(More)
Adipocyte differentiation is a complex developmental process forming adipocytes from various precursor cells. The murine 3T3-L1 preadipocyte cell line has been most frequently used in the studies of adipocyte differentiation. Differentiation of 3T3-L1 preadipocytes includes a medium containing fetal bovine serum (FBS) with hormonal induction. In this study,(More)
T cells are central players in the regulation of adaptive immunity and immune tolerance. In the periphery, T cell differentiation for maturation and effector function is regulated by a number of factors. Various factors such as antigens, co-stimulation signals, and cytokines regulate T cell differentiation into functionally specialized effector and(More)
Microbial metabolites, such as short-chain fatty acids (SCFAs), are highly produced in the intestine and potentially regulate the immune system. We studied the function of SCFAs in the regulation of T-cell differentiation into effector and regulatory T cells. We report that SCFAs can directly promote T-cell differentiation into T cells producing(More)
Progesterone, a key female sex hormone with pleiotropic functions in maintenance of pregnancy, has profound effects on regulation of immune responses. We report in this work a novel function of progesterone in regulation of naive cord blood (CB) fetal T cell differentiation into key T regulatory cell (Treg) subsets. Progesterone drives allogeneic(More)
α(4) and β(7) integrins, such as α(4)β(1), α(4)β(7), and α(E)β(7), are major integrins required for migration of leukocytes into mucosal tissues. The mechanisms responsible for coordinated expression of these three integrins have been poorly elucidated to date. We report that expression of the Itg-α(4) subunit by both CD4(+) and CD8(+) T cells requires the(More)
