We have isolated a human genomic clone that encodes the glucose-responsive protein GRP78 and have used this cloned gene probe, together with a cloned HSP70 gene, to study the expression of both stress-induced genes in response to inhibitors of cellular metabolism. On the basis of the effects of this group of chemicals on GRP78 and HSP70 expression, we have identified three classes of stress gen...
We studied the effect of protein-bound polysaccharide PSK on the activation of the human natural killer cell line NKL. We observed an increased natural killer cytotoxic activity against different tumor cells (K562, Daudi, and U937) when a standard 2- to 3-h 51chromium release assay was performed. The results parallel those obtained after treatment of the NKL cell line with interleukin-2. The hi...
The serine/threonine kinase LKB1 has a conserved role in Drosophila and nematodes to co-ordinate cell metabolism. During T lymphocyte development in the thymus, progenitors need to synchronize increased metabolism with the onset of proliferation and differentiation to ensure that they can meet the energy requirements for development. The present study explores the role of LKB1 in this process a...
We have herein studied the effect of pentoxifylline (PTX) on the adhesion and activation of human T lymphocytes. We found that PTX inhibited the adhesion of T cells to the beta1 and beta2 integrin ligands VCAM-1 and ICAM-1; this inhibitory activity was dose dependent, with a maximal effect from 12 to 24 h. We also found that PTX was able to interfere with the activation of beta1 integrins induc...
