Migratory dermal γδ T cells determine the balance between lung immunity and tissue damage during helminth infection.

Migratory dermal γδ T cells orchestrate lung immune responses and prevent tissue damage during helminth infection, with IL-17 production linked to their migration.

• Why it matters: Understanding how immune signals are transmitted across tissues during parasitic infections is crucial for developing interventions that protect vital organs like the lungs from damage while controlling parasites.
• What they did: The study used a percutaneous infection model with Nippostrongylus brasiliensis and analyzed dermal γδ T cell activation, migration, and their role in lung immunity, focusing on IL-17 and IFN-γ responses.
• The result: Blocking dermal γδ T cell migration reduced lung IL-17 levels, increased IFN-γ, and led to greater lung tissue damage, revealing a skin-lung axis vital for balancing immunity and tissue integrity.
