Researchers investigated SARS-CoV-2 responses in 222 donors from Central Africa, Europe and East Asia. They found disparities in immune responses due to blood cell composition, latent cytomegalovirus infection and human genetic factors. These population differences may help improve patient management in future epidemics.
Researchers at University of Bristol found that Long Covid is not caused by an immune inflammatory reaction to COVID-19. Instead, persistent immune activation and inflammation may persist for months after COVID-19, correlating with severe disease. The study suggests a new direction for understanding and potentially treating this debili...
The study found that the number of babies born in Minnesota with CMV decreased from 1 in every 200 births to 1 in every 1,000 births between August 2020 and December 2021. This decline is attributed to strict hygienic precautions such as masking, hand-washing, and infection prevention behaviors.
Researchers found that mothers who didn't transmit HCMV to their infants had higher levels of antibody-dependent cellular phagocytosis, suggesting a non-neutralizing immunity mechanism. This finding has implications for the development of effective HCMV vaccines.
Researchers at Gladstone Institutes have developed a novel class of therapeutics called feedback disruptors that target viral proteins' negative feedback loops. These drugs break the genetic feedback circuits, causing infected cells to self-destruct and stopping infection in its tracks.
Researchers at the University of Córdoba discovered that cytomegalovirus (CMV) accelerates immune system decline in all ages, not just the elderly. CMV reactivation leads to pro-inflammatory cell expansion, increasing cardiovascular disease risk by 20%.
Infants who contract cytomegalovirus (CMV) before age 12 months are at a significantly higher risk of developing TB later in their childhood. The study found that babies infected with CMV were more than three times more likely to develop TB after age 1 than children who had not become infected with CMV.
A new saliva test for congenital cytomegalovirus (cCMV) has been shown to be feasible and well-received by parents, with high uptake and accuracy rates. The test could lead to early diagnosis and treatment of cCMV-related hearing loss and neurodevelopmental disorders.
Researchers discover that cytomegalovirus enters a dormant state by varying protein levels in viral particles, allowing the virus to survive and persist for life. This 'bet-hedging' strategy enables the virus to balance between infectiousness and latency.
A new study has found that cystic fibrosis patients who have a common virus may experience faster disease progression. Cytomegalovirus infection was the most important factor linked to disease progression, with patients having the virus referred for lung transplants at a much younger age and dying ten years earlier on average.
Researchers identified a potential pathway for creating effective treatments against CMV, a common viral infection that can be deadly for stem cell transplant patients. A serum containing antibodies matched to the infecting viral strain prevented CMV reactivation after periods of dormancy.
