The innate immune system plays a crucial role in regulating host-microbe interactions, and especially in providing protection against pathogens that invade the mucosa. Using an intestinal infection ...

Research reveals that T cells from the adaptive immune system can manipulate the memory of innate immune cells. Previously, it was believed that the memory of innate immune cells operated ...

Human immunodeficiency virus 1, more commonly known as HIV-1, is known for its uncanny ability to evade the immune system. Scientists at Scripps Research and collaborators have now uncovered how our ...

Innate Immunity is a nonspecific host defense mechanism against foreign antigens. It is the first line of defense in a host and occurs immediately or within hours after exposure. This type of immunity ...

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 ...

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 ...

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, ...

The more severe the COVID-19 infection, the slower the recovery of immune cells, such as the dendritic cells, which are necessary for the activation of the immune system. This is shown by researchers ...

Pioneering research led by Brazilians describes the immune system's reactions in detail in the first living patient to receive a genetically modified pig kidney transplant.
