Recent advances in the therapeutic uses of chondroitinase ABC.

Recent advances in the therapeutic uses of chondroitinase ABC. Exp Neurol. 2019 Aug 06;:113032 Authors: Muir E, De Winter F, Verhaagen J, Fawcett J Abstract Many studies, using pre-clinical models of SCI, have demonstrated the efficacy of chondroitinase ABC as a treatment for spinal cord injury and this has been confirmed in laboratories worldwide and in several animal models. The aim of this review is report the current state of research in the field and to compare the relative efficacies of these new interventions to improve outcomes in both acute and chronic models of SCI. We also report new methods of chondroitinase delivery and the outcomes of two clinical trials using the enzyme to treat spinal cord injury in dogs and disc herniation in human patients. Recent studies have assessed the outcomes of combining chondroitinase with other strategies known to promote recovery following spinal cord injury and new approaches. Evidence is emerging that one of the most powerful combinations is that of chondroitinase with cell transplants. The particular benefits of each of the different cell types used for these transplant experiments are discussed. Combining chondroitinase with rehabilitation also improves outcomes. Gene therapy is an efficient method of enzyme delivery to the injured spinal cord and circumvents the issue of the enzyme's thermo-instability. Other methods of delivery, such as via nanoparticles or synthetic scaffolds, have shown promise; howeve...

In this study, researchers studied 438,952 participants in the UK Biobank, who had a total of 24,980 major coronary events - defined as the first occurrence of non-fatal heart attack, ischaemic stroke, or death due to coronary heart disease. They used an approach called Mendelian randomisation, which uses naturally occurring genetic differences to randomly divide the participants into groups, mimicking the effects of running a clinical trial. People with genes associated with lower blood pressure, lower LDL cholesterol, and a combination of both were put into different groups, and compared against those without thes...

In this study we show, for the first time, significant alterations in cholesterol efflux capacity in adolescents throughout the range of BMI, a relationship between six circulating adipocyte-derived EVs microRNAs targeting ABCA1 and cholesterol efflux capacity, and in vitro alterations of cholesterol efflux in macrophages exposed to visceral adipose tissue adipocyte-derived EVs acquired from human subjects. These results suggest that adipocyte-derived EVs, and their microRNA content, may play a critical role in the early pathological development of ASCVD.

Conclusion The expression of the components of the PTN-MK-RPTPβ/ζ axis in immune cells and in inflammatory diseases suggests important roles for this axis in inflammation. Pleiotrophin has been recently identified as a limiting factor of metainflammation, a chronic pathological state that contributes to neuroinflammation and neurodegeneration. Pleiotrophin also seems to potentiate acute neuroinflammation independently of the inflammatory stimulus while MK seems to play different -even opposite- roles in acute neuroinflammation depending on the stimulus. Which are the functions of MK and PTN in chronic neuroinfla...

In conclusion, this is the first report to show that pyroptotic cell death occurs in the aging brain and that the inflammasome can be a viable target to decrease the oxidative stress that occurs as a result of aging. Reducing Levels of Protein Manufacture Slows Measures of Aging in Nematodes https://www.fightaging.org/archives/2018/12/reducing-levels-of-protein-manufacture-slows-measures-of-aging-in-nematodes/ Researchers here demonstrate that an antibiotic slows aging in nematode worms, providing evidence for it to work through a reduction in protein synthesis. Beyond a slowing of aging, one of the con...

In this study, we analyzed FGF21 levels and alterations in the expression of genes encoding components of the FGF21-responsive molecular machinery in adipose tissue from aged individuals so as to ascertain whether altered FGF21 responsiveness that develops with aging jeopardizes human health and/or accelerates metabolic disturbances associated with aging. We studied a cohort of 28 healthy elderly individuals (≥70 years) with no overt signs of metabolic or other pathologies and compared them with a cohort of 35 young healthy controls (≤40 years). Serum FGF21 levels were significantly increased in elderly indiv...

CONCLUSION: The high rate of muscle-invasive bladder cancer and aggressive patterns justify neuro-urological follow-up, even before 15 years of neurogenic bladder. LEVEL OF EVIDENCE: 4. PMID: 29174817 [PubMed - as supplied by publisher]

Over 100 million Americans ― close to a third of the total population ― suffer from neurological diseases such as Alzheimer’s, multiple sclerosis, migraines, epilepsy and spinal cord injury.  These conditions put an enormous financial strain on the health care system, totaling nearly $800 billion in annual costs, according to a new report published in the journal Annals of Neurology. To put that into perspective, the figure exceeds the U.S. military budget by over $100 billion.  That number reflects the total cost of the nine most common neurological diseases, but the total costs related to th...

In this study, a PET camera was used to examine individual differences in the D2 system in a group consisting of 181 healthy individuals between the age of 64 and 68. All participants also had to take part in an all-inclusive performance test of the long-term episodic memory, working memory and processing speed along with an MRI assessment (which was used to measure the size of various parts of the brain). Researchers could see that the D2 system was positively linked to episodic memory, but not to working memory or to processing speed by relating PET registrations to the cognitive data. Researchers could also see that the...
