Abstract: Low doses of IL-2 are administered to potentiate an immune response after antiviral treatment. IL-2 is also administered in conjunction with immunotherapy to enhance the immune response to infection.

Abstract: A method of activating the immune system of a subject comprises the chronic administration of low doses of an agent having cytokine activity, including natural and recombinant cytokines, fragments, analogues, fusion proteins, and derivatives thereof, that are pharmaceutically acceptable, and their mixtures with other biologically active agents and formulation ingredients. The agent is provided as a unit dosage form, in systemic and topical product form, as an implant, inhalant, transdermal delivery device, and ultrasound and electrotransport devices, as well as in the form of a kit for self-administration.

Abstract: A method for producing a complementary DNA (cDNA) library enriched in ligand-inducible genes of a cell is described. The method includes activating a cellular ligand receptor for a predetermined period of time in the presence of labelled RNA precursors and a substance which enhances the level of RNA in the cell. The RNA precursors are incorporated into the RNA synthesized by the cell in response to receptor activation. The labelled RNA is separated from unlabelled RNA and used to prepare cDNA. The cDNA is cloned into host cells to provide a cDNA library of cDNA-containing clones, which is then screened for clones containing ligand-induced genes. Also described are several novel ligand-induced genes identified using the method of the invention.

Abstract: A new cellular protein produced by activated T cells and involved in the high affinity binding of interleukin-2 has been discovered. This protein has a molecular weight of about 75,000 (Mr) and is further characterized as having an affinity for IL-2 (in the absence of other receptor proteins) of about 10.sup.-9 molar and is substantially unreactive with anti-Tac antibodies. This new cellular protein, referred to herein as the ".alpha. chain," is believed to interact with the previously isolated 55,000 dalton receptor protein (referred to herein as the ".beta. chain") to form the high affinity interleukin-2 receptor which triggers the growth and mitosis of T cells during an immune response. Methods for isolating and purifying the .alpha. chain protein are disclosed herein as well as techniques for cloning and expressing the protein and related materials. Techniques for raising monoclonal antibodies to such proteins are also disclosed.

Abstract: Method and apparatus for increasing the effective data storage transfer rate in a system to permit the recording of a rapid sequence of high resolution images by eliminating and hence not transferring designated portions of each image in the sequence.

Abstract: A method of emission tomography using a gamma camera and a rotating collimator having an array of a large number of slanted, small diameter holes. A planar projection corresponding to each angular orientation assumed by the collimator is recorded. From these series of planar projections, a three-dimensional simulation model is reconstructed by an iterative algorithm which approximates the emitting object. The simulated model comprises multiple separable planes.
