Unraveling profibrotic pathways in the kidney
Fibrosis is a hallmark of chronic kidney disease that is characterized by accumulation of extracellular matrix and an influx of immune cells. Autophosphorylation of serine residues within the type II TGF-β receptor (TβRII) following activa...

MicroRNA-regulated network promotes pulmonary hypertension
Pulmonary hypertension is a complex disease that affects multiple vascular cell types, and mircoRNAs (miRNAs) have been implicated in the pathogenesis of this condition. In this episode, Stephen Chan discusses how his group used network theory to id...

Examining RASA1 in vascular malformation
Capillary malformation-arteriovenous malformation (CM-AVM) results from inactivating mutations in the gene encoding RAS p21 protein activator (RASA1); however, RASA1 is expressed in multiple tissues, and it is not clear how RASA1 m...

Dendritic cell-dependent inhibition of malaria immunity
Induction of type I interferon (IFN) signaling is critical for host defense against most viruses; however, for some pathogens, including the parasite that causes malaria, induction of type I IFN-mediated pathways enhances host susceptibility to dise...

Broadly neutralizing HIV-1 antibody identified in a lupus patient
Broadly neutralizing antibodies (BnAbs) represent a promising strategy for targeting rapidly mutating viruses, such as HIV-1. BnAbs recognize conserved epitopes and display unique characteristics that suggest that their development may be limited by...

Pancreatic cancer properties describe gemcitabine response
Pancreatic ductal adenocarcinoma (PDAC) is one of the most deadly forms of cancer, primarily due to the resistance of PDAC tumors to current therapeutic strategies. Several lines of evidence suggest that ineffective delivery of chemotherapy agents t...
