 | Rutgers researchers have uncovered a new way to stimulate activity of immune cell opiate receptors, leading to efficient tumor cell clearance. The researchers have been able to take a new pharmacological approach to activate the immune cells to prevent cancer growth through stimulation of the opiate receptors found on immune cells. ...> Full Article |
Scientists have discovered an Achilles heel within our cells that bacteria are able to exploit to cause and spread infection.

A new study helps to resolve an ongoing controversy about whether Langerhans cells (LCs) in human skin function to suppress the immune response and promote tolerance to normal human skin and its "friendly" microbial flora or mobilize a lethal attack against harmful foreign invaders. The research, published online May 3 in the journal Immunity by Cell Press, reveals that, depending on the situation, these versatile immune cells can perform either function.

Having a virtual copy of a patient's blood in a computer would be a boon to researchers and doctors. They could examine a simulated heart attack caused by blood clotting in a diseased coronary artery and see if a drug like aspirin would be effective in reducing the size of such a clot.

UCLA bioengineering researchers have taken advantage of cell physical properties for the development of a new instrument that slams cells against a wall of fluid and quickly analyzes the physical response, allowing identification of cancer and other cell states without chemical tags. The deformability cytometer consists of a miniaturized microfluidic chip that sequentially aligns cells so that they hit a wall of fluid at rates of thousands per second.

Researchers at Brigham and Women's Hospital could change the playing field of man versus bacteria. Charles Serhan, Ph.D., director of the BWH Experimental Therapeutics and Reperfusion Injury Center, has identified pathways of naturally occurring molecules in our bodies that can enhance antibiotic performance.

A team of chemical engineers led by Paul J. Dauenhauer of the University of Massachusetts Amherst has discovered a new, high-yield method of producing the key ingredient used to make plastic bottles from biomass. The process is inexpensive and currently creates the chemical p-xylene with an efficient yield of 75-percent, using most of the biomass feedstock, Dauenhauer says. The research is published in the journal ACS Catalysis.
