Ultraviolet B exposure expands proenkephalin+ regulatory T cells with a healing function

Ultraviolet B (UVB) is used as an effective therapy for individuals with psoriasis and atopic dermatitis because it has an immunosuppressive effect. The immune system develops to protect the body from infection or cancer. Its activation affects many physiological functions. Regulatory T (Treg) cells, expressing CD25 and Foxp3, constitute about 5-10% of peripheral CD4+T cells and work as brake on […]

Adult stem cells/glaucoma drug combo promotes diabetic wound healing in mice

A new study released today in Stem Cells Translational Medicine shows promise of a major breakthrough in healing chronic foot ulcers resulting from diabetes. The study, by researchers at the University of California, Davis, is the first to demonstrate how a bioengineered scaffold made up of human mesenchymal stem cells (MSCs) combined with timolol—a drug commonly used to treat glaucoma—improved […]

Here’s how cancer hijacks wound healing to create its own blood supply

Researchers at the University of Virginia School of Medicine have shed light on how cancers hijack the body’s natural wound-healing response to grow and spread. The researchers have identified specific processes within endothelial cells – the cells that line blood vessels – that tumors use to build out their own blood supply. These processes are normally used by the body […]

Do essential oils have any healing benefits, or are they just a fad?

Using the essential oils of plants and flowers to improve one's health or mood has been practised since ancient Egyptian times. But aromatherapy, as we now call it, is currently having a boom. Hundreds of thousands of Australians are buying and using these botanic compounds in a bid to improve health and wellbeing. Vara Maranda, who has practised and taught […]

Mechanism of impaired wound healing in diabetes identified

Researchers at Karolinska Institutet in Sweden have identified a mechanism that can explain the impaired wound healing in diabetes which can lead to diabetic foot ulcers. The study is published in the scientific journal Proceedings of the National Academy of Sciences. In diabetic mice, wound healing improved when the identified signalling pathway was blocked. Diabetic foot ulcerations are a common […]

Stop cancer before it breaks out: researchers now know how that can go

In each cell the potential for renewal, even in cancer cells. That’s what makes them so dangerous, but also vulnerable. Researchers exploit the weaknesses of the individual tumor cells. You want to detect on and off, before the cancer occurs. Autophagy is a process by which each cell degrades in our body faulty molecules and their chemical components recycled, then […]
