Cellular neuroinflammation in a lateral forceps compression model of spinal cord injury.

Postinjury inflammation has been implicated in secondary degeneration following injury to the spinal cord. The cellular inflammatory response to injury has not been described in the lateral compression injury model, although various types of compression injuries account for ∼20% of human spinal cord injuries (SCI). Here, we used forceps to induce a moderate compression injury to the thoracic spinal cord of female Sprague-Dawley rats.

Are there enhanced MBP autoantibodies in autism?

Autoantibodies to central nervous system antigens, such as myelin basic protein (MBP), may play a role in autism. We measured autoantibody titers to MBP in children with autism, both classic onset and regressive onset forms, controls (healthy age- and gender-matched) and individuals with Tourette syndrome via enzyme-linked immunosorbent assays. We found a significant difference in autoantibody titers to MBP, not accounted for by age or medication, between Tourette and classic autism (both significantly lower) when compared to regressive autism, but not when compared to controls.

How relevant are GFAP autoantibodies in autism and Tourette Syndrome?

Controversy exists over the role of autoantibodies to central nervous system antigens in autism and Tourette Syndrome. We investigated plasma autoantibody titers to glial fibrillary acidic protein (GFAP) in children with classic onset (33) and regressive onset (26) autism, controls (25, healthy age- and gender-matched) and individuals with Tourette Syndrome (24) by enzyme-linked immunosorbent assays. We found a significant difference in autoantibody titers to GFAP, not accounted for by age, between the Tourette (significantly lower) and regressive autism groups.
