TNO Preventie en Gezondheid (author), Bayley, J.P. (author), Bakker, A.M. (author), Kaijzel, E.L. (author), Wierenga, E.A. (author), van der Pouw-Kraan, T.C.T.M. (author), Huizinga, T.W.J. (author), Verweij, C.L. (author)The occurrence of monoallelic expression of cytokine genes in single cells has been convincingly demonstrated, but there have been few reports of this phenomenon in T cell clones. Here we describe studies on the expression of alleles of the human genes encoding IL-2, IL-3, IL-4, and IL-13 in human CD4+ T cell clones. In contrast to the results...article 2003

To eliminate campylobacter from the pig population, a top-down approach, involving the breeding and reproduction farms, seems appropriate.
