  • ALS Toponome Analyzes of cell surfaces of immune cells in the blood have shown that ALS has a specific abnormal topon. An essential feature is the existence of aberrant T-lymphocytes, which in addition to the CD8 receptor also express the CD16 receptor complex. Exactly the same cell forms are found in the morphologically well-preserved ALS postmortem tissue within postcapillary venules of the spinal pyramidal tract ( Figure 1 a, b; Box).
  • CD8 / CD16 complexes are required by "forward transport" for the transmigration of these cells through the endothelial cell layer via vesicle budding in the cell surface to promote transmigration as part of an abnormal "homing code” (CD16)

  • CD16 is necessary to control the abnormal homing aberrant CD8 cells into the pyramidal tract, and when this homing process is complete, the cells degrade (lose) the CD16 complex, then migrate as CD8 + CD16 cells between the cells
  • This process is obviously primarily autonomous, as the cells are never observed in the context of ZeH "debris," which is a sign of primary neuronal degradation, so the cells play a primary pathogenetic role supported by the fact that downregulation of CD16 leads to a halt of disease progression: when CD16 is no longer available as in Figure 1f, the endothelial homing process can no longer be performed are therefore described as a disease of the Immunzelltoponoms that by means of a highly selective "homing codes" the ALS speci fish pyramidal tract lesions (axotomy) generated. Many genetic findings and protein aggregations described in ALS have also been described in experimental axotomy, so that immunocelltoponomically-mediated axotomy explains these findings.

All of these proteins thus represent therapeutic target structures (targets) individually or in combination with CD8 and / or CD16, since switching off these proteins-for example by means of appropriate antibodies / ligands and / or genetic engineering methods-leads to a collapse of the intracellular information flow and thus to a loss of function of the aberrant cells.
