New study suggests way to slow skin fibrosis in scleroderma

The prognosis for sufferers recognized with scleroderma -- an autoimmune illness characterised by fibrosis of the pores and skin -- is just not usually a rosy one. With restricted therapy choices accessible, these affected by the dysfunction can face disabling hardening and tightening of their pores and skin. Scleroderma also can have an effect on the blood vessels, lungs and different inner organs.
New and ongoing analysis at Hospital for Particular Surgical procedure in New York Metropolis has recognized a attainable mechanism behind the fibrosis that happens in scleroderma -- a mechanism that will someday result in a therapy for the illness.
Revealed within the Journal of Scientific Investigation on October 10, the research stories that in laboratory analysis, a inhabitants of stem cells referred to as "adipose-derived stromal cells (ADSCs)" is lowered in quantity within the layer of fats sitting underneath the pores and skin. It seems that lack of these ADSCs might contribute to the pores and skin fibrosis attribute of scleroderma.
Furthermore, the research authors discovered that the survival of these ADSCs that do stay beneath the pores and skin in scleroderma are depending on immune cells referred to as "dendritic cells." Dendritic cells launch a compound referred to as lymphotoxin B that promotes ADSC survival; when antibodies that stimulate the lymphotoxin B receptor had been administered with ADSCs to replenish the misplaced ADSCs, ADSC survival was discovered to be elevated, suggesting a method for reversing the fibrosis of the pores and skin.
"Injecting ADSCs is being tried in scleroderma; the potential for stimulating the lymphotoxin B pathway to extend the survival of those stem cells could be very thrilling," says lead research creator Theresa T. Lu, MD, PhD. "By uncovering these mechanisms and focusing on them with remedies, maybe someday we are able to higher deal with the illness."
Dr. Lu additionally feels this technique could possibly be used to focus on stem-cells from different tissue sources so as to deal with rheumatological and different situations -- resembling lupus and rheumatoid arthritis -- and likewise to facilitate bone and cartilage restore.
Within the coming years, Dr. Lu and her colleagues hope to check the applicability of their work in human cells, which might present scleroderma sufferers with a welcome therapy choice if confirmed protected and efficient. "Enhancing ADSC remedy could be a serious profit to the sphere of rheumatology and to sufferers affected by scleroderma," she says.

Scientists show how mutation causes incurable premature aging disease

The study findings provide a drug target for the disease, said lead study author Jayakrishnan Nandakumar, assistant professor of molecular, cellular and developmental biology at the University of Michigan. The mutation compromises the function of an enzyme known as telomerase , which fuels stem cell division, he said. Stem cells must divide to repair old tissue. This mutation, which occurs in the telomere protein TPP1, causes stem cells to slow or stop dividing in people with this rare, incurable disease. This can cause tissue breakdown, premature aging, bone marrow failure, cancer and even death. Nandakumar and his U-M colleagues are believed to be the first to use genome editing technology called CRISPR/CAS9 to introduce a dyskeratosis congenita mutation into human cells. This gene editing technology is often described as a pair of molecular scissors, because it cuts DNA in precise locations to allow for additions, deletions and replacements of DNA near the cut. The acronym...

Breakthrough in production of dopamine neurons for Parkinson's disease

"In our preclinical assessments of stem cell-derived dopamine neurons we noticed that the outcome in animal models varied dramatically, even though the cells were very similar at the time of transplantation. This has been frustrating and puzzling, and has significantly delayed the establishment of clinical cell production protocols," says Malin Parmar, who led the study conducted at Lund University as part of the EU network NeuroStemcellRepair . The Lund experiments use modern global gene expression studies to better understand the path from a stem cell to a dopamine neuron. The data has been generated in close collaboration with a team of scientists at Karolinska Institute lead by Professor Thomas Perlmann, and is closely linked with a second study from the same cluster of scientists. The second study sheds new light on how dopamine neurons are formed during development, and what makes them different from other similar and neighbouring neurons. This new insight has ena...
