In order to fight pathogens, mast cells regulate inflammatory reactions of the immune system. Both mast cells and neutrophils are white blood cells and are critical for the body's immune defense.
Ultra-small nanomedicines of approximately 18 nm were fabricated by dynamic ion-pairing between Y-shaped block copolymers and nucleic acid drugs, such as siRNA and antisense drugs.
To mark Allergy Awareness Week (19-25 October), two leading allergy charities are urging parents and teachers to ‘Check It, Don’t Chance It’ to ensure pupils and young adults with allergies are safe in schools.
