Platelets promote epileptic seizures by modulating brain serotonin level, enhancing neuronal electric activity, and contributing to neuroinflammation and oxidative stress.

The drugs currently available for treating epilepsy are only partially effective in managing this condition. Therefore, it is crucial to investigate new pathways that induce and promote epilepsy development. Previously, we found that platelets interact with neuronal glycolipids and actively secrete pro-inflammatory mediators during central nervous system (CNS) pathological conditions such as neuroinflammation and traumatic brain injury (TBI).

Fresh evidence for major brain gangliosides as a target for the treatment of Alzheimer's disease.

Although it was suggested that gangliosides play an important role in the binding of amyloid fragments to neuronal cells, the exact role of gangliosides in Alzheimer's disease (AD) pathology remains unclear. To understand the role of gangliosides in AD pathology in vivo, we crossed st3gal5-deficient (ST3) mice that lack major brain gangliosides GM1, GD1a, GD3, GT1b, and GQ1b with 5XFAD transgenic mice that overexpress 3 mutant human amyloid proteins AP695 and 2 presenilin PS1 genes. We found that ST3 5XFAD mice have a significantly reduced burden of amyloid depositions, low level of neuroinflammation, and did not exhibit neuronal loss or synaptic dysfunction.
