Conventional dendritic cells are playing a pivotal role at the interface of innate and adaptive immunity, but they are a heterogenous group regarding function and regulation. Here, the authors show that although Bcl6-deficiency does not regulate general DC subset identity, Bcl6 expression is required for a specific subset of type 2 DCs in mice, resulting in impaired T helper cell responses and further clarifying molecular players driving DC subset heterogeneity.
