The immune system can work in two ways: the innate immune system reacts to any foreign invaders that are identified by immune cells that look for such pathogens; but the acquired or adaptive immune ...

The body’s innate immune system senses damage signals, like heat shock proteins (HSP70), and sounds the alarm, mobilizing dendritic cells to fan the flames of inflammation.

However, recent research has challenged this belief, showing that the innate immune system can be trained. This emerging principle, known as trained innate immunity, enables the innate immune system ...

How does the immune system respond to a pathogen? The immune system has two main arms: innate and adaptive. The innate immune system recognizes broad molecular patterns, such as molecules that certain ...

Now, researchers from Penn’s School of Dental Medicine and international collaborators have investigated the effects of training the innate immune system in experimental models of two chronic ...

Studies have shown that the innate immune system can respond more strongly when challenged again with the same or different stimulus—in other words, it can be “trained.” ...

By studying the innate immune system, scientists have found connections between the immune systems of bacteria and those of humans. “We only started sequencing large numbers of genomes about 20 years ...

The novel coronavirus 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 ...

Meyer and her team continue to dissect the complicated lives of immune system agents such as innate-like T cells. The findings pave the way for future research and may help to advance immunotherapies.
