Not all acne is equal: Scientists reveal strains of C. acnes that promote skin health

Added: 09.11.2021 19:52 | 303 views | 0 comments

Researchers reveal correlation between ribotype (RT) strains of Cutibacterium acnes, which are found in human skin, and the lifespan of the nematode Caenorhabditis elegans. Strains RT4 and 8, which are associated with acne in human skin, shortened the lifespan of the nematode, while RT6, which are predominantly found in healthy human skin, did not. Also, it was found that the healthy skin-related RT6 strain of C. acnes improved C. elegans resistance to the pathogenic organism Staphylococcus aureus.

Mechanism behind ineffective psoriasis drugs identified

Added: 09.11.2021 19:52 | 309 views | 0 comments

Interleukin-12 -- a messenger molecule of immune cells -- was long considered to trigger the development of psoriasis. Now, researchers have shown that interleukin-12 does not actually cause the skin disease but protects against it. This also explains why common psoriasis drugs that block the messenger show insufficient treatment efficacy.

New, promising opportunities for treating skin fibrosis

Added: 09.11.2021 19:52 | 322 views | 0 comments

Collagen, the main component of the skin's extracellular matrix, can cause a pathological condition if it is in excess. Applying an electric field to the skin affects collagen pathways, temporarily reducing collagen production and increasing its degradation. These results open new therapeutic perspectives for the topical treatment of skin fibrosis characterized by excessive collagen deposition.

Skin stem cells get moving for enhanced skin regeneration

Added: 09.11.2021 19:52 | 318 views | 0 comments

Researchers have found that the ability of skin stem cells to heal wounds is linked with their ability to move towards the injury. Their study identified the signalling pathway of EGFR and COL17A1 as a key player in the regulation of motility. Understanding mechanisms that underlie the age-associated reduction in regenerative capacity is the first step to develop targeted treatments for age-associated chronic nonhealing disorders, such as diabetic ulcers.

Stem cell transplant: How skin-derived T cells can damage other organs

Added: 09.11.2021 19:52 | 382 views | 0 comments

More than 40,000 allogeneic hematopoietic stem cell transplants are carried out worldwide every year, mostly for patients suffering from leukemia or other diseases of the hematopoietic system. Very often, the so-called graft-versus-host reaction occurs, an inflammatory disease that can affect different organs and is caused by an unwanted defense reaction of the donor cells and the body's own T cells. Scientists now show how these endogenous, tissue-derived T cells enter other organs, such as the intestine, via the blood and contribute to inflammation there. The study provides important approaches to better therapy in stem cell transplantation and new diagnostic options.

Unraveling the mystery of touch

Added: 09.11.2021 19:52 | 306 views | 0 comments

Researchers uncover mechanism that underlies the exquisite sensitivity of certain skin surfaces. The analysis, conducted in mice, reveals that the higher sensitivity of certain regions of the skin stems from a greater number of and stronger connections between neurons in these regions and corresponding brain areas that receive signals from them. The findings set the stage for better understanding the mechanisms that underlie abnormalities of touch seen in certain neurodevelopmental disorders in humans.

An international agreement to protect the ozone layer is expected to prevent 443 million cases of skin cancer and 63 million cataract cases for people born in the United States through the end of this century, according to new research. The research team developed a computer modeling approach that revealed the effect of the Montreal Protocol and subsequent amendments on stratospheric ozone, the associated reductions in ultraviolet radiation, and the resulting health benefits.

Tracking muscle activity with clothes on your back

Added: 09.11.2021 19:52 | 299 views | 0 comments

Researchers have developed a bioelectrical sensor that is convenient and low-cost. The sensor measures electromyography signals that are generated in muscles when they contract and are useful for studying muscle fatigue and recovery, and they have the potential to inform diagnosis and treatment of neuromuscular diseases. The biosensor, made of silver paste with a layer of gold nanoparticles on top, is directly integrated onto a piece of clothing. The result was a detector that was both conductive and nonirritating to the skin.

Natural killer cells do not just kill cancer cells or cells infected with viruses, they also mediate a trade-off between wound healing and bacterial defense in skin wounds. If the healing process is accelerated, the immune defense is weakened, researchers have now shown.
