摘要:
There is disclosed a polypeptide (CD40-L) and DNA sequences, vectors and transformed host cells useful in providing CD40-L polypeptides. More particularly, this invention provides isolated human and murine CD40-L polypeptides that bind to the extracellular binding region of a CD40 receptor. Also disclosed are methods of simulating hybridoma cells to increase monoclonal antibody production by administering a CD40 ligand polypeptide that stimulates B cell proliferation.

More particularly, this invention provides isolated human and murine CD40-L polypeptides that bind to the extracellular binding region of a CD40 receptor. Also disclosed are methods of inhibiting undesirable immune responses, preventing T cell interaction with B cells by blocking CD40L binding to CD40 sites on B cells and other target cells.

摘要:
There is disclosed a method of detecting a mutation in a CD40 ligand gene, comprising isolating nucleic acid from an individual, selectively amplifying nucleic acid derived from the CD40 ligand gene, and analyzing the amplified nucleic acid to determine if there is a mutation (or mutations) in the CD40 ligand gene. The ability of a CD40 ligand protein expressed from the gene may be determined. Methods of treating individuals exhibiting a defective CD40 ligand gene (i.e., X-linked hyper IgM patients and certain individuals afflicted with combined variable immunodeficiency) are also disclosed. Also disclosed are non-human animals that lack functional CD40 ligand as a result of gene targeting technology.

Methods of treating a syndrome that results in elevated levels of serum IgM and diminished levels of all other isotypes of immunoglobulins are also disclosed. Also disclosed are non-human animals that lack functional CD40 ligand as a result of gene targeting technology.
