Tissue Paper Made of Various Organs for Use in Wound Healing, Regenerative Medicine, Hormone Production
If you thought sheepskin paper, also known as vellum, is gross, get ready for “tissue paper” from Northwestern University. The material, made from organs mixed with a polymer in a multi-step process, may have a number of uses that are obvious, such as wound repair, and others that will have to be discovered. The tissue paper is...

Transforming skin cells to insulin
Researchers at the University of Bergen have transformed skin puncture cells from diabetes patients into insulin producing cells, using stem cell techniques. The researchers’ aim is to transplant these cells under the skin of people with diabetes. “This study is a step towards discovering how “stand-in” cells can secrete insulin in the body,” says Professor...

Azithromycin tied to poor airflow decline-free survival after HSCT
(HealthDay)—For patients after allogeneic hematopoietic stem cell transplant (HSCT), early administration of azithromycin is associated with worse airflow decline-free survival, according to a study published in the Aug. 8 issue of the Journal of the American Medical Association. Anne Bergeron, M.D., Ph.D., from the Hôpital Saint-Louis in Paris, and colleagues randomized patients to receive azithromycin or placebo three...

Scientists make critical insights into T-cell development
Mutations in the gene encoding the enzyme protein tyrosine phosphatase N2 (PTPN2) have been associated with the development of autoimmune disease including Type 1 diabetes, Crohn’s Disease and rheumatoid arthritis. In important fundamental research, Monash University researchers have identified a crucial part of the enzyme’s role in early T-cell development, and have shown that decreased levels...

New insight into how immune cells are formed
In contrast to what has been previously believed, development of blood stem cells to mast cells, a type of specialised immune cell, does not depend on a growth factor called stem cell factor. This has been demonstrated in a new collaborative study by researchers at Karolinska Institutet and Uppsala University, and published in the scientific...

Checkpoint inhibitors fire up different types of T cells to attack tumors
Anti-CTLA-4 and anti-PD-1 immunotherapies expand distinct immune infiltrates against cancer Cancer immunotherapies that block two different checkpoints on T cells launch immune attacks on cancer by expanding distinct types of T cell that infiltrate tumors, researchers from The University of Texas MD Anderson Cancer Center report in the journal Cell. “The mechanisms these two therapies use mostly...

New type of blood cells work as indicators of autoimmunity
A team from Instituto de Medicina Molecular Lisboa, led by Luis Graça, has analyzed blood samples from patients with Sjögren syndrome, an autoimmune disease that affects the mucous membranes and moisture-secreting glands of the eyes and mouth, and found that these patients have a significant increase in a specific immune cell type called T follicular...
