In a large-animal model study, researchers have found that heart attack recovery is aided by injection of heart muscle cell spheroids derived from human induced pluripotent stem cells, or hiPSCs, that overexpress cyclin D2 and are knocked out for human leukocyte antigen classes I and II. This research used a pig model of heart attacks.

Cells degrade components that are no longer needed through autophagy. New results show that a weak molecular interaction is essential for this process. By modifying this interaction, it is possible to artificially trigger autophagy, which could then enable the degradation of deposits in neurodegenerative diseases such as Alzheimer's, or support cancer therapies.

Knowing who may progress along the disease pathway is critical for early diagnosis and intervention, improved treatment and better disease management, according to a team that has developed a new method to predict the progression of autoimmune disease among those with preclinical symptoms. The team used artificial intelligence (AI) to analyze data from electronic health records and large genetic studies of people with autoimmune disease to come up with a risk prediction score. When compared to existing models, this methodology was between 25% and 1,000% more accurate in determining whose symptoms would move to advanced disease.
