When immune cells move throughout the brain, they act as the first line of defense against viruses, toxic materials and damaged neurons, rushing over to clear out them. Researchers at Indiana University School of Medicine have been investigating how these immune cells in the brain—microglia—relate to a gene mutation recently found in Alzheimer’s disease patients. They published their findings today […]

In a paper published recently in Pharmacological Reviews, Emory University School of Medicine researchers outlined the impact of inflammation on motivation as it relates to depression. The researchers propose that low grade inflammation affects brain chemicals and brain circuits that regulate motivation, ultimately leading to motivational deficits and a loss of interest or willingness to engage in usually pleasurable activities […]

A team of Massachusetts General Hospital (MGH) researchers has discovered how an important class of anti-cancer drugs called PARP inhibitors works, a finding that could help improve treatment and prolong survival for patients with breast cancer and other malignancies. PARP (poly[ADP-ribose] polymerase) inhibitors such as olaparib (Lynparza), rucaparib (Rubraca) and niraparib (Zejula) are used to treat patients with cancers of […]

A team of scientists from Loyola University Chicago’s Stritch School of Medicine have discovered a critical component for renewing the heart’s molecular motor, which breaks down in heart failure. Approximately 6.2 million Americans have heart failure, an often fatal condition characterized by the heart’s inability to pump enough blood and oxygen throughout the body. This discovery could represent a novel […]

University of Miami Miller School of Medicine researchers are the first to demonstrate that COVID-19 can be present in the penis tissue long after men recover from the virus. The widespread blood vessel dysfunction, or endothelial dysfunction, that results from the COVID-19 infection could then contribute to erectile dysfunction, or ED, according to the study recently published in the World […]
