Double negative T cells mediate Lag3-dependent antigen-specific protection in allergic asthma

Abstract

Allergic asthma symptoms may be controlled, but currently no effective therapy exist to address the underlying pathology. Here the authors show, using mouse model of adoptive cell transfer, that CD4-CD8- T cells can suppress the function of dendritic cells and T follicular helper cells via Lag3 to provide allergen-specific protection from asthma.
