    摘要: In a method for preparing an animal model for the human immune system in a non-human mammal, human stem cells with hematopoietic potential are transplanted into a non-human mammal. The non-human mammal is conditioned with cell culture supernatant of a culture of human cell lines, cells and/or tissue. The cell culture supernatant is derived from cell lines producing cytokines and other molecular mediators.

    摘要: The present invention relates to, among others, an in vitro method of modifying a cell graft containing immune cells comprising the steps of incubating a cell graft containing immune cells with an anti CD4 antibody wherein said incubating is carried out for from 1 minute to 7 days, b) removing unbound antibody from said graft; as well as to corresponding modified grafts and uses. The invention further relates to the modification of antibodies reactive to the CD4 human leukocyte antigen to provide anti-CD4 antibodies that have a reduced number of potential T-cell epitopes but retain the ability to bind to CD4, such as to an anti human CD4-antibody comprising a heavy chain immunoglobulin variable domain (VH) and a light chain immunoglobulin variable domain (VL), wherein at least one T cell epitope located outside the CDRs of said immunoglobulin variable domains is removed from said immunoglobulin variable domains. Preferably, the specificity and mode of action of the anti-CD4 antibodies are not affected by the modification(s).

    摘要: The invention concerns the 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 certain cell populations which comprise CD4-bearing cells in human individuals.In addition the invention concerns a composition which comprises a labelled ligand having specificity for the CD4 molecule and CD4-bearing cells or particles, and a method for determining the extent and progression of diseases in which human CD4-bearing cells are of clinical importance.
