Method of treating multiple sclerosis and related t-cell initiated tissue destruction by administering HSA/CD24
View Patent ↗Methods for blocking autoreactive T cell-initiated destruction of tissues in a mammal are provided. In one embodiment, the methods involve administering an HAS/CD24 polypeptide or fragment thereof. In some embodiments, the polypeptide or fragment is glycosylated.
1. A method for treating a human patient suspected of having, known to have, or predisposed to having multiple sclerosis, said method comprising:
administering to said patient a pharmaceutical composition comprising an isolated human HSA/CD24 polypeptide fusion and a physiologically acceptable carrier,
wherein the HSA/CD24 polypeptide fusion comprises a HSA/CD24 core region,
wherein the HSA/CD24 fusion comprises the HSA/CD24 polypeptide linked by a peptide bond to the hinge-CH2- CH3 region of human immunoglobulin G1, and
wherein the HSA/CD24 polypeptide fusion is glycosylated.
2. The method of claim 1 , wherein the HSA/CD24 polypeptide fusion is produced by expression in a mammalian host cell.
3. The method of claim 1 , wherein the pharmaceutical composition is administered when the patient has clinical symptoms of multiple sclerosis.
4. The method of claim 1 , wherein the pharmaceutical composition is administered when the patient is in temporary remission from symptoms of multiple sclerosis.
5. The method of claim 1 , wherein the HSA/CD24 polypeptide fusion further comprises the N-terminal HSA/CD24 signal peptide.
6. The method of claim 2 , wherein the host cell is a CHO cell.
