B cells are the immune cells responsible for creating antibodies, and most B cells, known as B2 cells, produce antibodies in response to a pathogen or a vaccine, providing defense and immunity against infections. But a small subset of long-lived B cells, known as B1 cells, are quite different fromContinuar Leyendo

Curiosity is the motivational drive for exploring and investigating the unknown and making new discoveries. It is as essential and intrinsic for survival as hunger. Until recently, the brain mechanisms underlying curiosity and novelty seeking behavior were unclear. However, researchers from the Netherlands Institute for Neuroscience have now discovered aContinuar Leyendo

Epidemic. Pandemic. These terms have become second nature to us, popping up in everyday conversation, and for good reason — COVID-19 is the latest pandemic to pose a threat to humanity. Blacksburg, May 14, 2021.- But in recent months, far less attention has been paid to another widely spread problemContinuar Leyendo

Neurodegenerative diseases such as Alzheimer’s, Parkinson’s and ALS affect millions of adults, but scientists still do not know what causes these diseases, which poses a significant roadblock to developing treatments or preventative measures. Gainesville, May 08, 2021.- Recent research suggests that people with these conditions exhibit changes in the bacterialContinuar Leyendo

Next-generation gene sequencing (NGS) technologies — in which millions of DNA molecules are simultaneously but individually analyzed — theoretically provides researchers and clinicians the ability to noninvasively identify mutations in the blood stream. Identifying such mutations enables earlier diagnosis of cancer and can inform treatment decisions. Johns Hopkins Kimmel CancerContinuar Leyendo

A new study is drawing the most detailed picture yet of SARS-CoV-2 infection in the lung, revealing mechanisms that result in lethal COVID-19, and may explain long-term complications and show how COVID-19 differs from other infectious diseases. New York, May 03, 2021.- Led by researchers at Columbia University Vagelos CollegeContinuar Leyendo

A multidisciplinary team of researchers from Duke-NUS Medical School and the Agency for Science, Technology and Research (A*STAR) in Singapore discovered a new mitochondrial peptide called MOCCI that plays an important role in regulating inflammation of blood vessel and immunity. The study, published in the journal Nature Communications, revealed howContinuar Leyendo

For reasons not yet clear, pregnant women infected with the virus that causes COVID-19 are more likely to experience preterm births, pre-eclampsia, and other neonatal problems than non-infected women. New Haven, CT, April 24, 2021.- A team of Yale scientists decided to investigate whether the virus could be affecting placentalContinuar Leyendo

In a worldwide study of 2,100 pregnant women, those who contracted COVID-19 during pregnancy were 20 times more likely to die than those who did not contract the virus. Oxford, April 23, 2021.- UW Medicine and University of Oxford doctors led this first-of-its-kind study, published today in JAMA Pediatrics. TheContinuar Leyendo
