    摘要: The present disclosure describes, in part, methods for treating a degenerative and vascular disease of the retina and/or posterior segment of the eye in a subject, the method comprising administering to a subject an effective amount of an antibody or fragment thereof that binds to the same epitope as an antibody comprising a heavy chain variable region and a light chain variable region, wherein: (a) the heavy the heavy chain variable region comprises a sequence having at least 85% sequence identity to SEQ ID NO: 4 and the light chain variable region comprises a sequence having at least 85% sequence identity to SEQ ID NO: 5 wherein the antibody inhibits TREM2 cleavage; or (b) the heavy the heavy chain variable region comprises a sequence having at least 85% sequence identity to SEQ ID NO: 6 and the light chain variable region comprises a sequence having at least 85% sequence identity to SEQ ID NO:7, and wherein the antibody inhibits TREM2 cleavage; or (c) the heavy the heavy chain variable region comprises a sequence having at least 85% sequence identity to SEQ ID NO: 8 and the light chain variable region comprises a sequence having at least 85% sequence identity to SEQ ID NO:9 or to SEQ ID NO:87, and wherein the antibody inhibits TREM2 cleavage; or (d) the heavy the heavy chain variable region comprises a sequence having at least 85% sequence identity to SEQ ID NO: 10 and the light chain variable region comprises a sequence having at least 85% sequence identity to SEQ ID NO:11 or to SEQ ID NO:12 or to SEQ ID NO:13 or to SEQ ID NO:14, and wherein the antibody inhibits TREM2 cleavage. and methods of screening for a molecule which specifically binds to and inhibits cleavage of human TREM2 between His157 and/or Ser158 on the surface of retinal microglial cells by ADAM10 and/or ADAM17.
