New research conducted in monkeys reveals that T cells are not critical for the recovery of primates from acute COVID-19 infections.
An international team of researchers from the Max Planck Institute for Plant Breeding Research and the University of Åarhus in Denmark have discovered that bacteria from the plant microbiota are adapted to their host species. In a newly published study, they show how root-associated bacteria have a competitive advantage when colonizing their native host, which allows them to invade an already established microbiota.
Researchers at Cornell have developed a way to analyze how individual immune cells react to the bacteria that cause tuberculosis. It could pave the way for new vaccine strategies and provide insights into fighting other infectious diseases.
Over the last few decades, neurodegenerative diseases became one of the top 10 global causes of death. Researchers worldwide are making a strong effort to understand neurodegenerative diseases pathogenesis, which is essential to develop efficient treatments against these incurable diseases. A team of researchers found out the implication of lysosomes in the spread of Parkinson's disease.
Replication of SARS-CoV-2, the virus responsible for COVID-19, depends on a series of interactions between viral proteins and different cellular partners such as nucleic acids (DNA or RNA). Characterizing these interactions is crucial to elucidate the process of viral replication and identify new drugs for treating COVID-19.
Infection with dengue virus makes mosquitoes more sensitive to warmer temperatures, according to new research led by Penn State researchers. The team also found that infection with the bacterium Wolbachia, which has recently been used to control viral infections in mosquitoes, also increases the thermal sensitivity of the insects. The findings suggest that global warming could limit the spread of dengue fever but could also limit the effectiveness of Wolbachia as a biological control agent.
Two recently published studies indicate Epstein-Barr virus (EBV) reactivation may play a role both in the development of long COVID symptoms, as well as severe COVID-19 cases. A study in Pathogens found over 73% of COVID-19 patients who were experiencing long Covid symptoms were also positive for EBV reactivation. A study in Scientific Reports by Nature found EBV reactivation was also associated with COVID-19 severity.
In a new study, researchers have uncovered how cytolysins from Enterococcus faecalis destroys bacterial and mammalian cells.
The tiny organisms living in soil may have a greater effect on the yield and pest and disease resistance of crop plants grown in that soil than previously known.
Natto, a fermented soybean dish often served for breakfast in Japan, originated at the turn of the last millennium but may hold an answer to a modern problem: COVID-19, according to a new study based on cell cultures.
