CD103+ dendritic cell - fibroblast crosstalk via TLR9, TDO2, and AHR signaling drives lung fibrogenesis.

Idiopathic pulmonary fibrosis (IPF) is characterized by progressive scarring and loss of lung function. With limited treatment options, patients succumb to the disease within 2 to 5 years. The molecular pathogenesis of IPF regarding the immunologic changes that occur is poorly understood.

Dengue and Zika virus NS4B proteins differ in topology and in determinants of ER membrane protein complex dependency.

Flaviviruses utilize the cellular endoplasmic reticulum (ER) for all aspects of their lifecycle. Genome replication and other viral activities take place in structures called replication organelles (ROs), which are invaginations induced in the ER membrane. Among the required elements for RO formation is the biogenesis of viral nonstructural proteins NS4A and NS4B.
