Brain tissue yields clues to causes of PTSD

A post-mortem analysis of brain tissue from people who had been diagnosed with post-traumatic stress disorder (PTSD) may help explain enduring mysteries about the disorder, such as why women are more susceptible to it and whether a dampened immune system response plays a role in dealing with stress, a team headed by Yale University researchers

Virus that causes COVID-19 puts a plug in cellular defenses

One of the novel coronavirus’ most insidious tricks is that it can block the ability of cells to produce protective proteins without hindering its own ability to replicate. Now, a multidisciplinary team of Yale researchers has discovered how SARS-CoV-2, the virus that causes COVID-19, accomplishes this trick by blocking production of cellular proteins, including immune

Overactive enzyme causes hereditary hypertension

A Turkish family from a village near the Black Sea caught the attention of medical researchers in the early 1970s, when a physician discovered that many members of this large family had both unusually short fingers and astronomically high blood pressure, sometimes twice as high as that of healthy people. Those affected die around the

Missing protein in brain causes behaviors mirroring autism

Scientists at Rutgers University-Newark have discovered that when a key protein needed to generate new brain cells during prenatal and early childhood development is missing, part of the brain goes haywire—causing an imbalance in its circuitry that can lead to long-term cognitive and movement behaviors characteristic of autism spectrum disorder. “During brain development, there is

Parkinson’s disease: Evidence suggests this common complaint may be an early warning sign

Parkinson’s disease is a degenerative brain disease that causes body tremors, rigid muscles, and difficulty walking and talking. The disease disrupts the body’s autonomic nervous system, which controls spontaneous body processes such as heart rate, digestion, salivation, and bowel function. People tend to experience symptoms later in the course of the disease, but a common
