Abstract: Chimeric G-protein linked receptors are constructed which retain ligand binding specificity yet gain the ability to elevate intracellular free calcium as a result of agonist binding. This easily assayed function is provided by the insertion of or replacement with sequences substantially homologous to the i3 loop of a second G-protein-linked receptor. Such receptors are employed, for example, in methods of screening for compounds capable of acting as agonists or antagonists of G-protein-linked receptors.

Abstract: An apparatus and method are disclosed for culturing cells by flowing a medium through a packed bed of biocompatible macroporous ceramic particles disposed in a cell-culture reactor. In one embodiment, oxygen and other nutrients in the medium are transported significantly by convective flow through pores of the biocompatible macroporous ceramic particles to cells disposed within the pores. Oxygen can be introduced to the cell-culture reactor by sparging oxygen gas into the cell-culture reactor. Oxygen content in the medium can also be increased by increasing the solubility of oxygen in the medium, such as by adding perfluorocarbon or other oxygen carriers to the medium. The oxygen capacity of the reactor can be further increased by sparging oxygen-containing gas into the medium at a plurality of points in the packed bed, or by introducing oxygen gas to the medium through a solid-phase oxygen gas-permeable membrane disposed in the packed bed.

Methods of producing the mammalian monokines are taught. The monokines are implicated in immunological and inflammatory processes, as are other members of the platelet factor 4 family of cytokines.

Abstract: The present invention relates to nucleic acid sequences encoding brain derived neurotrophic factor (BDNF), as well as BDNF protein produced in quantity using these nucleic acid sequences, as well as fragments and derivatives thereof. In addition, the invention relates to pharmacologic compositions and therapeutic uses of BDNF, having provided, for the first time, the means to generate sufficient quantities of substantially pure BDNF for clinical use. In a specific embodiment, BDNF may be used to promote the survival of substantia nigra dopaminergic neurons and basal forebrain cholinergic neurons, thereby providing a method for treating, respectively, Parkinson's disease and Alzheimer's disease. The invention also relates to antibodies directed toward BDNF or fragments thereof, having provided a method for generating sufficient immunogen.

Abstract: A method for the mass growth of cells (2) which consists in growing the cells (2) in a thin film, e.g. a bubble or foam, of nutrient medium (4), which is continuously recirculated to the bulk medium (1) for replenishing. Growth rate and yields obtained with this method in large scale cell culturing are far superior to those obtained by know methods, due to the increased metabolic exchange of the cells (2) with the environment.
