| abstract |
A polypeptide comprising a crystallizable fragment (Fc) region of IgG for use in prevention or treatment of a disease, particularly a disease affecting the central nervous system. The polypeptide is administered locally to the affected compartment, in particular to the central nervous system. The Fc region bears a modification resulting in reduced affinity to the neonatal Fc receptor (FcRn), resulting in an increased brain to serum concentration of the polypeptide. |
