New Study Identifies Key Immune Cells Behind Itchy Mosquito Bites

Research reveals how GD3 cells and IL-3 molecules trigger nerve responses, offering potential for new allergy treatments.

Scientists found that GD3 immune cells produce IL-3 molecules, which prime sensory neurons to react to allergens.
Blocking IL-3 or removing GD3 cells in mice prevented allergic reactions and itchiness.
The study suggests a pathway that could be targeted to treat chronic itch disorders.
Researchers emphasize the need to verify these findings in human cells.
The findings highlight how immune and nervous systems interact in allergic responses.
