Single-cell RNA seq developed to accurately quantify cell-specific drug effects in pancreatic islets
by CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences The pancreas is an abdominal organ that produces digestive enzymes as well as hormones that regulate blood sugar levels. This hormone-producing function is localized to the islets of Langerhans, which constitute clusters of different endocrine cell types. Among those are beta cells,...

Scientists discover new compound which could improve photodynamic therapy for cancer
UNIVERSITY OF SHEFFIELD PDT does not always kill cells deep within a cancerous tumour, allowing tumours to grow back again. The new compound uses penetrating infrared light to damage cells directly and potentially improve the success rate of PDT Researchers at the University of Sheffield have synthesized a new compound which could improve the success...

A Unique Amino Acid for Brain Cancer Therapy
Photodynamic therapy is often used to treat brain tumors because of its specificity—it can target very small regions containing cancerous cells while sparing the normal cells around it from damage. It works by injecting a drug called a photosensitizer into the bloodstream, where it gathers in cells, and then exposing the drug-filled cells to light....
