Rag-GTPases play roles in sensing nutrient availability, and it is not fully known how they contribute to energy-consuming immunological processes such as the B cell response. Here authors show that genomic deletion fo RagA/RagB distrupts both T-dependent and T-independent humoral immune responses, independent of mechanistic target of rapamycin complex 1 but involving the transcription factors TFEB and TFE3.
