Researchers have discovered a new population of macrophages, important innate immune cells that populate the lungs after injury caused by respiratory viruses. These macrophages are instrumental in repairing the pulmonary alveoli. This groundbreaking discovery promises to revolutionize our understanding of the post-infectious immune response and opens the door to new regenerative therapies.

Known for their role in allergic reactions, mast cells have long been recognised as key players in our immune system. When they encounter allergens, they release chemicals that trigger typical allergy symptoms such as tissue swelling and inflammation. Now, researchers have discovered a hidden talent of mast cells: they can capture and use another type of immune cell called neutrophils. This surprising discovery sheds new light on how our immune system works, particularly during allergic reactions.
