Fuente: WIPO "biotechnology" The immunoadhesions of the present invention are useful in treating rhinovirus infections. The immunoadhesions contain a chimeric ICAM molecule and may optionally also contain J chain and secretory compounds. The chimeric ICAM molecule is a fusion protein that has a rhinovirus receptor protein linked to an immunoglobulin protein. This invention also includes the greatly increased and improved method of producing immunoadhesions in plants. Each of the components of an immunoadhesin is produced in a plant cell and thereby assembles within the plant cell. This method of producing the immunoadhesions of the present invention results in the efficient and economic production of these molecules. The present invention also contemplates the production of immunoadhesions in a variety of eukaryotic cells including plants and mammalian cells. The immunoadhesions of the present invention are useful as a therapeutic against the common cold in humans which is caused by rhinoviruses.
