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, ...

Tiny immune cells called microglia protect the central nervous system (CNS) in a multitude of ways: They provide innate ...

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 ...

Our immune system is divided into two main branches: innate and adaptive. Innate immune cells act as a first line of defense, quickly responding to invaders, while adaptive immune cells take a longer ...

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 ...

What keeps some immune systems youthful and effective in warding off age-related diseases? In a new paper published in Cellular & Molecular Immunology, USC Stem Cell scientist Rong Lu and her ...

In several disease conditions, including infections and cancers, innate immune activation and nutrient scarcity occur ...

Regulatory T cells (Treg cells), a specialized type of immune cell, are usually seen as "peacekeepers" that prevent excessive ...

When fighting disease, our immune cells need to reach their target quickly. Researchers have now discovered that immune cells actively generate their own guidance system to navigate through complex ...

YOU MIGHT KNOW them as the “powerhouses of the cell,” but that’s selling mitochondria short—these microscopic MVPs play a ...
