However, adaptive immune cells—so-named because they can recognize, respond to, and remember specific microbes—require four to seven days to mount a tailor-made defensive. 1 Meanwhile, innate immune ...

SARS-CoV-2 has an enzyme that can counteract a cell's innate defense mechanism against viruses, explaining why it is more infectious than the previous SARS and MERS-causing viruses. The discovery may ...

Scientists generally agree that eukaryotes, the domain of life whose cells contain nuclei and that includes almost all multicellular organisms, originated from a process involving the symbiotic union ...

Filoviruses are negative-sense and single-stranded ribonucleic acid (RNA) viruses. The most well-known human-infecting filoviruses are marburgviruses and ebolaviruses. Infection can result in ...

A new review by Dr. Ruyuan Wang and an international team of researchers explores the complex interactions between the innate and adaptive immune systems, shedding light on regulatory mechanisms in ...

If the COVID-19 pandemic has done one thing, it’s made us all more familiar with some of the important players in the immune system. Antibodies, B cells, and T cells are among the best known parts of ...

Researchers have discovered the molecular mechanism by which the innate immune system recognizes HIV-1, potentially contributing to the development of future treatments. HIV-1 is a virus that actively ...

For decades, dogma dictated that the immune system consisted of two separate branches. Cells of the innate system respond rapidly to molecular patterns shared by a broad array of pathogens. Meanwhile, ...

Two proteins ensure that cells can take up iron when needed. If both control proteins are switched off in mice, the animals develop severe anemia, as expected. At the same time, surprisingly, a cell ...
