Why should the immune system not be “boosted,” but instead supported through consistent, healthy habits? Learn how the immune ...

Different pathways within the cell are activated or silenced dependent on the external signals acting on a cell. One such pathway includes the stimulator of interferon genes (STING) pathway which acts ...

The immune system has two separate responses, which are orchestrated to optimize protection against pathogens. The first response is known as innate immunity. This first wave of protection provides ...

Innate immunity, orchestrated by pattern recognition receptors (PRRs) including TLRs, NLRs, and the cGAS–STING pathway, forms the foundation of host ...

When pathogens attack the body, the innate immune system goes to work protecting against the invading disease. The innate immune system is the first line of defense. It detects precisely what the ...

Dozens of new discoveries reveal that defenses evolved by bacteria and viruses billions of years ago still define our own ...

When a transplanted organ arrives, it’s like a controlled burn that risks becoming a wildfire. The body’s innate immune system senses damage signals, like heat shock proteins (HSP70), and sounds the ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American The very first line of defence against any ...

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 ...
