A new study published in Biological Psychiatry suggests that autism is associated with reductions in the level of cellular adhesion molecules in the blood, where they play a role in immune function.
Cell adhesion molecules are the glue that binds cells together in the body. Deficits in adhesion molecules would be expected to compromise processes at the interfaces between cells, influencing tissue integrity and cell-to-cell signaling. In the brain, deficits in adhesion molecules could compromise brain development and communication between nerve cells.
Over the years, deficits in neural cell adhesion molecules have been implicated in schizophrenia and other psychiatric disorders. One adhesion molecule, neurexin, is strongly implicated in the heritable risk for autism.
