The role of soluble intercellular adhesion molecules in neurodegenerative disorders

The presence of high s-ICAM values may be related to immunological processes involved in pathogenetic mechanisms of AD. The not statistically significant values of s-E selectin, a glycoprotein considered an exclusive marker of endothelial activation, seem to suggest the neural rather than the endothelial s-ICAM origin in patients with AD. The low values of s-ICAM-1 and sE-selectin in the serum of ALS patients do not exclude the presence of an unconventional immunological abnormality in this disorder.
