USE OF A LABELLED LIGAND HAVING SPECIFICITY FOR THE HUMAN CD4 MOLECULE TO PRODUCE A DIAGNOSTIC AGENT FOR ANALYSING MIGRATION AND/OR DISTRIBUTION PATTERNS OF CELL POPULATIONS

摘要

The invention relates to the use of a labeled ligand having human CD4specificity for producing a diagnostic used in the analysis of migrationand/or distribution patterns of certain cell populations that comprise CD4carrying cells in human individuals. The invention further relates to acomposition that comprises a labeled ligand that is specific for the CD4molecule and for CD4 carrying cells or particles, and to a method fordetermining the extent and the progression of diseases in which human CD4carrying cells have a clinical significance.
