Pesquisadores na Suécia criaram células produtoras de insulina a partir de células-tronco humanas que reverteram os sintomas do diabetes após serem transplantadas em camundongos. As células amadureceram após serem colocadas no olho e mantiveram a regulação da glicose por meses. O trabalho foi publicado na Stem Cell Reports.

Cientistas do Karolinska Institutet desenvolveram um protocolo aprimorado para derivar ilhotas pancreáticas a partir de várias linhagens de células-tronco pluripotentes humanas. O método utiliza condições de cultura refinadas e aglomerados tridimensionais para reduzir tipos celulares indesejados e aumentar a resposta à glicose.

Health ministry panel conditionally approves iPS cell products

A health ministry expert panel has conditionally approved two regenerative medicine products derived from induced pluripotent stem (iPS) cells for treating Parkinson's disease and severe heart disease. This marks a potential world first in commercializing Nobel Prize-winning stem cell technology. The approval, based on small-scale clinical trials confirming safety and presumed efficacy, requires post-market verification within seven years.

Researchers advance two-part therapy for type 1 diabetes

A team led by Leonardo Ferreira at the Medical University of South Carolina is developing a novel therapy combining lab-made insulin-producing cells with engineered immune cells to protect them. Funded by $1 million from Breakthrough T1D, the approach aims to restore beta cell function without immunosuppressive drugs. This strategy builds on prior research and targets all stages of the disease.

Scientists explain high altitude's protection against diabetes

21 de fevereiro de 2026 Reportado por IA

Researchers have identified why living at high altitudes reduces diabetes risk: red blood cells absorb excess glucose in low-oxygen conditions. This metabolic shift lowers blood sugar levels, as shown in mouse experiments. A new drug mimicking this effect reversed diabetes in mice, suggesting potential treatments.

Trojan horse obesity drug boosts weight loss in mice

Scientists have developed a hybrid obesity treatment that uses GLP-1 and GIP signals to deliver a metabolic enhancer directly into cells. Early tests in mice showed greater weight loss and better blood sugar control than standard therapies. The approach aims to reduce side effects by limiting the drug's action to targeted areas.

UC Riverside researchers report battery-powered oxygen gel that sped healing in diabetic mouse wounds

22 de fevereiro de 2026 Reportado por IA Verificado

Researchers at the University of California, Riverside say they have developed a flexible, battery-powered gel patch that generates oxygen inside hard-to-heal wounds—an approach aimed at countering deep-tissue oxygen deprivation that can stall recovery and contribute to amputations. In experiments in diabetic and older mice, the team reported that wounds that often remained open—and were sometimes fatal—closed in about 23 days when treated with the oxygen-generating patch.
