Summary
Synaptamide therapy effectively reduces brain damage biomarkers and reactive astrogliosis after traumatic brain injury (TBI). This treatment promotes anti-inflammatory astrocyte activation and neurotrophin synthesis, offering a promising therapeutic approach for TBI recovery.
Area of Science:
- Neuroscience
- Neuropharmacology
- Traumatic Brain Injury Research
Background:
- Traumatic brain injury (TBI) management often overlooks glial activation, a key factor in long-term cognitive decline.
- Endogenous lipid messengers, like N-acylethanolamines, are increasingly recognized for their role in neuropathologies.
- Synaptamide (N-docosahexaenoylethanolamine) exhibits anti-inflammatory, gliotropic, and neuroprotective properties crucial for brain repair.
Purpose of the Study:
- To investigate the effects of synaptamide on reactive astrogliosis in the cortex and thalamus following cerebral cortex injury in mice.
- To evaluate synaptamide's potential to mitigate TBI-induced neuropathology and promote neuroprotection.
Main Methods:
- Cerebral cortex injury model in mice.
- Administration of synaptamide (10 mg/kg/day for 7 days).
- Assessment of reactive astrogliosis, biomarker expression, astrocyte activation (A1/A2), and neurotrophin synthesis (Clcf1, BDNF) in brain tissue and blood.
Main Results:
- Synaptamide therapy significantly reduced expression of brain damage biomarkers in blood.
- Inhibition of reactive astrogliosis development was observed in treated mice.
- Synaptamide promoted the activation of anti-inflammatory A2 astrocytes and stimulated synthesis of neurotrophins (Clcf1, BDNF).
Conclusions:
- Synaptamide demonstrates significant therapeutic efficacy in reducing neuropathology associated with TBI.
- The compound's ability to modulate glial response and promote neurotrophic factors makes it a promising candidate for TBI treatment.
- Targeting glial activation with synaptamide offers a novel strategy for improving outcomes in patients with traumatic brain injury.

01:37Neural Regulation
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
01:05Long-term Depression
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

01:29Drugs Affecting Neurotransmitter Synthesis
Drugs affecting neurotransmitter synthesis can impact the adrenergic neuron and the synthesis of neurotransmitters. For example, α-methyltyrosine and carbidopa target specific enzymes involved in catecholamine synthesis. α-methyltyrosine inhibits the enzyme tyrosine hydroxylase, which converts tyrosine into dopamine. By blocking this enzyme, α-methyltyrosine reduces dopamine production and other catecholamines. Carbidopa, on the other hand, inhibits the enzyme dopa decarboxylase, which converts...
01:29Hepatic Encephalopathy
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
01:25Secondary Spinal Cord Injury llI: Pathophysiology
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
