Complement comprises a group of plasma and membrane proteins that provide an effective bridging function for innate and adaptive humoral immunity. Understanding complement pathophysiology is fundamental given that inappropriate complement function in host defence can lead to infectious diseases and inefficient disposal of altered, damaged or senescent cells can lead to or enhance autoimmune neurological processes. Although the rising number of approved drugs targeting complement pathways remains...

$100 million program to ensure water for industry overlooks shortage’s root causes, critics say

Duke University’s 850,000 specimens will move to the University of North Carolina at Chapel Hill

UCLA researchers have discovered two powerful influences that help guide how the human brain forms before birth. Radial glia, stem cells responsible for producing much of the cerebral cortex, change their behavior depending on how they process glucose and on physical contact with signals arriving from the thalamus. Those signals can alter which types of neurons are produced, including upper-layer neurons that are especially prominent in humans.

Duke researchers developed an injectable scaffold that helped stroke-damaged brains grow new blood vessels, support nerve regrowth, and recover movement in mice. The treatment appears to work partly by recruiting the body’s own immune cells, including neutrophils that may switch from damaging to helpful under the right conditions.

The proposed ban would come with tough penalties, but the path through Congress is uncertain

Iberian orcas have been ramming boats off the coast of Portugal and Spain. But what looks like vengeance may have a more benign explanation

Scientists discovered that more than 500 species of vesper bats possess two separate sets of antibody genes, an immune arrangement never before found in mammals. The surprising system could help explain how bats tolerate so many viruses without becoming seriously ill.
