SARS-CoV-2 infection affects energy stores in the body
An international research team found that SARS-CoV-2 infection alters mitochondria on a genetic level, leading to widespread “energy outages” throughout the body and its major organs. …
Clinics continue marketing unproven stem cell interventions as treatments for COVID-19 and Long COVID
Researchers have identified 38 businesses engaged in direct-to-consumer marketing of unproven stem cell treatments and exosome therapies for preventing and treating COVID-19. …
Viral persistence and serotonin reduction can cause long COVID symptoms
Components of the SARS-CoV-2 virus remain in the gut of some long COVID patients, causing persistent inflammation, serotonin reduction, vagus nerve dysfunction, and neurological symptoms. …
SARS-CoV-2 infects coronary arteries, increases plaque inflammation
SARS-CoV-2 can directly infect the arteries of the heart and cause the fatty plaque inside arteries to become highly inflamed, increasing the risk of heart attack and stroke. …
New material captures coronavirus particles and could transform face mask efficiency
A new material that captures coronavirus particles could make face masks approximately 93% more efficient, with little impact on breathability. …
Clues from patients with rheumatic diseases point to a potential driver of long COVID
Prior infection with a pre-pandemic coronavirus that causes the common cold may help set the stage for the development of long COVID. …
COVID-19 may trigger new-onset high blood pressure
An analysis of electronic medical records for more than 45,000 people found that COVID-19 infection was significantly associated with the development of high blood pressure in adults with preexisting heart conditions or those who were older, Black or male. …
Severe COVID-19 may lead to long-term innate immune system changes
New research finds severe COVID-19 may cause long-lasting alterations to the innate immune system, the first line of defense against pathogens, underscoring the importance of vaccinations. …
Surprise COVID-19 discovery helps explain how coronaviruses jump species
Unexpected new insights into how COVID-19 infects cells may help explain why coronaviruses are so good at jumping from species to species and will help scientists better predict how COVID-19 will evolve. …
Stress enhances antibody response after vaccination, but impairs immunological memory
Study shows that acute stress in mice after vaccination increases antibody response, but this comes at the price of reduced antibody breadth, which results in diminished protection against the pathogen’s variants. …
