Abstract

Nesfatin-1 has been demonstrated to possess anti-inflammatory and anti-apoptotic effects in the rat brain with subarachnoid hemorrhage. The study was designed to investigate the influence of nesfatin-1 on inflammatory responses and neuronal cell apoptosis after traumatic brain injury. Wistar rats were subjected to 5, 10 or 20 μg/kg of nesfatin-1 at designed time points (0.5, 2, 4 or 8h after head trauma) intraperitoneally. Rats were sacrificed at hours 2, 6 and 12, as well as day 1, 2, 3 and 5 after head trauma. The administration of 10 or 20 μg/kg of nesfatin-1 at hour 0.5 after head trauma could significantly suppress gene expressions of nuclear factor kappa-B, lessen concentrations of tumor necrosis factor-alpha, interleukin-1beta and interleukin-6, diminish caspase-3 activity as well as reduce number of apoptotic neuronal cells in traumatic rat brain tissues (P<0.05), but the administration of 5 μg/kg of nesfatin-1 not (P>0.05). Moreover, 20 μg/kg nesfatin-1 also significantly suppressed the inflammation and neuronal cell apoptosis when applied 2, 4 or 8h after head trauma. However, a clear concentration-response or time-response relationship was not found. These findings suggest that nesfatin-1 may inhibit nuclear factor k...Continue Reading

Anorexia nervosa (AN) is a psychiatric condition characterized by severe weight loss and secondary problems associated with malnutrition. Here is the latest research on AN.

Anti-inflammatory Treatments

A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Blood Brain Barrier

The blood brain barrier is a border that separates blood from cerebrospinal fluid. Discover the latest search on this highly selective semipermeable membrane here.

Blood Brain Barrier Chips

The blood brain barrier (BBB) is comprised of endothelial cells that regulate the influx and outflux of plasma concentrations. Lab-on-a-chip devices allow scientists to model diseases and mechanisms such as the passage of therapeutic antibodies across the BBB. Discover the latest research on BBB chips here.

Blood Brain Barrier & Cytokines

Some cytokines are able to cross the blood brain barrier through transport systems and enter the cerebrospinal fluid and interstitial fluid spaces. Here is the latest research on cytokines crossing the blood brain barrier and how this can affect tissues within the CNS.

Brain Injury & Trauma

brain injury after impact to the head is due to both immediate mechanical effects and delayed responses of neural tissues.
