Nanoparticle Chomps away Plaques that cause Heart Attacks

The dotted line outlines the atherosclerotic artery and the green represents our nanoparticles, which are in the plaque. The red indicates macrophages, which is the cell type that the nanoparticles are stimulating to eat the debris.

Michigan State University and Stanford University scientists have invented a nanoparticle that eats away – from the inside out – portions of plaques that cause heart attacks.

Bryan Smith, associate professor of biomedical engineering at MSU, and a team of scientists created a “Trojan Horse” nanoparticle that can be directed to eat debris, reducing and stabilizing plaque. The discovery could be a potential treatment for atherosclerosis, a leading cause of death in the United States.

The results, published in the current issue of Nature Nanotechno...

Parkinson’s Disease may start Before Birth

Stem cell study finds malfunctioning brain cells in patients who were diagnosed before age 50; researchers test potential new treatment. People who develop Parkinson’s disease before age 50 may have been born with disordered brain cells that went undetected for decades, according to new Cedars-Sinai research. The research points to a drug that potentially might help correct these disease processes.

Parkinson’s occurs when brain neurons that make dopamine, a substance that helps coordinate muscle movement, become impaired or die...

New Light Shed on Damaging Impact of Infrared and Visible Rays on Skin

Professor Mark Birch-Machin in the lab

The damage visible and infrared light can do to our skin has been revealed for the first time in new research by scientists at Newcastle University, UK.

The detrimental effects of exposure to the sun’s rays are well documented, and the main aim of sunscreens is to protect the skin against dangerous ultraviolet radiation (UV).

However, experts at Newcastle University have now scientifically proven that UV rays are not the only type that can penetrate deep into the skin, as visible and infared light can also harm our skin’s cells.

The study, published online today in The FASEB Journal, reveals that the deeper dermal layer of the skin is damaged by UV, visible and infared light and that it may be beneficial for anti-ageing to protect our s...

Novel Communication between Intestinal Microbes and developing Immune Cells in the Thymus

Early life entero-thymic communication: Complex interplay between intestinal microbes, host TLR2, pDCs and developing cells in the thymus 

Regulation of thymic immune development by intestinal microbes in early life. Researchers discover microbes regulate the development of specialized immune cells in the thymus that play a critical role in mucosal tolerance.

Newborns face unique immunological challenges immediately after birth. As they depart a relatively sterile fetal environment, they are abruptly exposed to a multitude of foreign antigens, the major burden of which is in the form of the microbiota newly colonizing the gastrointestinal tract...
