Abstract: This invention describes a novel means of introducing foreign genes and/or viruses, wildtype or recombinant, into plant cells via a seed treatment method using recombinant or wildtype furoviruses and their natural fungal vectors. Because of its ease of application, longevity of the seed treatment product, minimal risk of transmission to subsequent seed generations, specificity, and universality within a species, it offers a significant improvement over prior art techniques for viral mediated gene delivery techniques. The unique and critical aspect of the invention is the use of seed treatment technology for delivering foreign genes or viruses into plants for, for example, the enhancement of agronomic traits and production of desirable products such as pharmaceuticals.

Abstract: A therapeutic method of modulating the immune response, by administering to a patient an amount of IL-4 effective to promote peripheral blood lymphocyte adhesion to microvascular endothelial cells in lymphoid organs. The IL-4 is preferably coadministered with IL-1.beta..An improved method of screening a cell line for the production of a binding partner that binds with a cell adhesion molecule, by contacting the binding partner with IL4-activated and nonactivated microvascular endothelial cells, and selecting binding partners that bind to the IL4-activated microvascular endothelial cells but not to the nonactivated microvascular endothelial cells. The selected binding partners may thereafter be tested for the ability to block lymphocyte binding to cytokine-activated endothelial cells. The binding partners are preferably also characterized by binding to human VCAM-1 and to IL4- or TNF.alpha.-activated bone marrow stromal cells. A representative embodiment is mAb 6G10 produced by hybridoma ATTC No. HB 10519.

Abstract: A gene, flanking 5' and 3' sequences and derived cDNA encoding a rat D.sub.4 dopamine receptor that is predominantly located in the cardiovascular and retinal systems is disclosed. The cDNA has been expressed in transfected mammalian cells and demonstrated to preferentially bind dopamine antagonists such as clozapine. The cDNA is useful as a probe for related D.sub.4 dopamine receptors. Expressed in appropriate cell lines, it is useful as an in vitro screen for drugs which specifically bind to the receptor. Drugs that specifically bind to the receptor are then screened using standard methodology in rats, mice or dogs, for the physiological effects. Amino acids deduced from the determination of cDNA can be used to generate either polyclonal or monoclonal antibodies which recognize the D.sub.4 receptor sequence but do not recognize D.sub.1, D.sub.2, D.sub.3 or D.sub.5 dopamenergic receptors, for use in immunocytochemical studies, and for identification and isolation via flow sorting of D4 expressing cell types.
