Immune cells may heal bleeding brain after strokes

By studying rodents, researchers showed that instead of attacking germs, some neutrophils may help heal the brain after an intracerebral hemorrhage, a form of stroke caused by ruptured blood vessels. The study suggests that two neutrophil-related proteins may play critical roles in protecting the brain from stroke-induced damage and could be used as treatments for intracerebral hemorrhage.

Small intestine permeable peptides facilitate digestive tract absorption

Biopharmaceuticals, medium- and high-molecular weight biologically active macromolecules, are not easily absorbed by the small intestine, the main organ responsible for gastrointestinal absorption, resulting in a bottleneck for oral administration type biopharmaceutical development. Now, researchers have found a new small intestine permeable peptide that can facilitate digestive tract absorption of biopharmaceutical products. The discovery should make it possible for oral administration of drugs that were previously only available by injection.
