“Latent viruses, the kind we don't even know we have, can have subtle effects like being associated with the development of cancer (in the case of herpes simplex almost everyone carries one form of the virus). That's why it's very interesting that we may actually have a future in which these viruses can be removed from our genome, thanks to CRISPR.”

“As the COVID-19 global pandemic enters its second year, scientists now have data on some of the long-term effects of the infection, which is caused by the SARS-CoV-2 virus. A new report details the efficacy of the immune response months after beating the active infection.”

“The disease was eradicated, however, in 1980, after a global effort of vaccination, testing, and containment. Many deadly viruses remain, including Ebola virus and human immunodeficiency virus, and new viruses will likely emerge in the future.”

“Then, they exposed the cells to the SARS-CoV-2 virus and observed changes. The authors found that the SARS-CoV-2 virus infects adipose tissue from multiple depots around the body, but that macrophages were the main cell type infected.”

“Gut bacteria use flavonoids (found in fruits, teas, etc.) to control the immune response and protect against severe damage from the influenza virus (in mice). The specific human-associated gut microbe that protected against the influenza virus is called Clostridium orbiscindens.”

“Another concern is the risk of mother-to-child transmission of disease, also known as vertical transmission, which can occur during pregnancy. Several viruses, including hepatitis B, herpes varicella-zoster (chickenpox), and human immunodeficiency virus, can be passed via vertical transmission.”

“Finally, they found that the centenarians' gut viruses possessed an abundance of auxiliary metabolic genes involved in sulfate metabolism, the byproducts of which promote gut integrity and pathogen resistance.”

“Findings from a new study demonstrate that the SARS-CoV-2 virus targets the cardiomyocytes of the heart in the setting of COVID-19, causing myocarditis. SARS-CoV-2, the virus that causes COVID-19, exploits the ACE2 receptor to gain entry into cells.”

“A critical factor in containing SARS-CoV-2, the virus that causes COVID-19, is understanding how quickly the virus spreads. Findings from a new study indicate that the SARS-CoV-2 spreads quickly due to its short serial interval, often before carriers are symptomatic.”

“A commonly held theory was that previous exposure to an influenza virus conferred no immunological protection against subsequent exposure. However, new data suggest that immunological imprinting due to exposure to subtypes of influenza viruses during childhood may provide partial lifelong protection against other subtypes.”
