The importance of long-lived IgE plasma cells for protracted allergies

Key Points

• This research highlights the crucial role of long-lived IgE plasma cells in sustaining allergic responses.
• Utilized genetic fate mapping to trace cell origins.
• Applied single-cell sequencing to analyze IgE expression in selected populations.
• Identified long-lived IgE plasma cells as key contributors to sustained IgE levels.
• Confirmed type 2 memory B cells as another source of IgE.
• Highlighted the rarity and significance of both cell types in allergy.
