The microenvironment of tumors is a mix of cell types, mostly comprised of inflammatory cells. White blood cells, recruited from the blood and bone marrow, represent a significant portion of these inflammatory cells and influence nearly all steps of tumor progression.

State mandates requiring commercial health plans to cover the cost of services for children with autism spectrum disorder (ASD) have resulted in an increased number of children being diagnosed and treated for ASD, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

Three military veterans who are enrolled as graduate students at the University of Pennsylvania, John Schippert, Jonathan Wood and Matthew Miclette, have been appointed as 2016 Tillman Scholars through the Pat Tillman Foundation.

The growing trend of "do-it-yourself" transcranial direct current stimulation (tDCS) poses hidden risks to healthy members of the public who seek to use the technique for cognitive enhancement.

Despite increasing legalization of euthanasia and physician-assisted suicide (PAS) worldwide, the practice remains relatively rare and, when carried out, is primarily motivated by psychological factors such as loss of autonomy or enjoyment of life, rather than physical pain.

In a study with potentially major implications for the future treatment of autoimmunity and related conditions, scientists from the Perelman School of Medicine at the University of Pennsylvania have found a way to remove the subset of antibody-making cells that cause an autoimmune disease, without harming the rest of the immune system.

University of Pennsylvania engineers have developed a rapid, low-cost genetic test for the Zika virus. The $2 testing device, about the size of a soda can, does not require electricity or technical expertise to use. A patient would simply provide a saliva sample. Color-changing dye turns blue when the genetic assay detects the presence of the virus.

Adult stem cells represent a sort of blank clay from which a myriad of different cell and tissue types are molded and as such are of critical importance to health, ageing and disease.  In tissues that turn over rapidly, such as the intestines, the self-renewing nature of stem cells and their susceptibility to cancer-causing mutations has led researchers to postulate that

Switching to reduced nicotine content (RNC) cigarettes may not necessarily reduce harm to smokers, according to new research conducted by Penn’s Center for Interdisciplinary Research on Nicotine Addiction (CIRNA). Smokers also tend to ignore cautions contained in warning box labels, the authors found in a separate study.
