Article
Translating genome-wide association study (GWAS) loci into causal variants and genes requires accurate cell-type-specific enhancer-gene maps from disease-relevant tissues. Building enhancer-gene maps is essential but challenging with current experimental methods in primary human tissues. Here we developed a nonparametric statistical method, SCENT (...

Tuberculosis (TB) caused by Mycobacterium tuberculosis ( Mtb ) infects up to a quarter of the world’s population. Although immune responses can control Mtb infection, 5%–10% of infected individuals can progress to active TB disease (progressors). A myriad of host factors regulate disease progression in TB and a better understanding of immune correl...

Influenza is a highly contagious, acute respiratory disease that causes significant public health and economic threats. Influenza infection induces various inflammatory mediators, IFNs, and recruitment of inflammatory cells in the host. This inflammatory “cytokine storm” is thought to play a role in influenza-induced lung pathogenesis. Empagliflozi...
Article
The human leukocyte antigen (HLA) locus plays a critical role in complex traits spanning autoimmune and infectious diseases, transplantation and cancer. While coding variation in HLA genes has been extensively documented, regulatory genetic variation modulating HLA expression levels has not been comprehensively investigated. Here we mapped expressi...

The ADP ribosyl transferases (PARPs 1-17) regulate diverse cellular processes, including DNA damage repair. PARPs are classified based on their ability to catalyze poly-ADP-ribosylation (PARylation) or mono-ADP-ribosylation (MARylation). While PARP9 mRNA expression is significantly increased in progressive human tuberculosis (TB), its participation...
