"A pathological and very complex autoimmune reaction of the skin": This is the definition doctors and scientists use to describe psoriasis, a disease that affects one to three percent of the population. It is characterized by accelerated cell division in the upper dermal layers with proliferated skin cells and an inflammation of the skin beneath. Many different cells are involved in the complex processes: skin cells (keratinocytes) and cells of the immune system, among others T lymphocytes, macrophages, mast cells and others.

Understanding the underlying mechanisms that lead to psoriasis

Added: 25.01.2020 19:20 | 3 views | 0 comments

Psoriasis is an inflammatory skin condition that affects some 125 million people worldwide. It is characterized by itchy, scaly skin plaques. The exact cause of psoriasis is unclear. But mounting evidence implicates the immune system in the overproduction of cell-signalling molecules called cytokines, which stimulate skin cells called keratinocytes to express genes that maintain an inflammatory microenvironment. Now, scientists have found more evidence that a cytokine called IL-17A is especially critical in this process.

One of the causes of breast cancer may be inflammation triggered by harmful bacteria suggest researchers. Scientists advise consuming natural yogurt, which contains beneficial bacteria which dampens inflammation and which is similar to the bacteria found in breastfeeding mothers. Their suggestion is that this bacteria is protective because breast feeding reduces the risk of breast cancer. The consumption of yogurt is also associated with a reduction in the risk of breast cancer.
