Guarding the frontiers: the biology of type III interferons

Nature Immunology, 2015
Type III interferons (IFNs) or IFN-λs regulate a similar set of genes as type I IFNs, but whereas type I IFNs act globally, IFN-λs primarily target mucosal epithelial cells and protect them against the frequent viral attacks that are typical for barrier ...

A new type of identification problems: optimizing the fractional order in a nonlocal evolution equation [PDF]

, 2016
In this paper, we consider a rather general linear evolution equation of fractional type, namely a diffusion type problem in which the diffusion operator is the $s$th power of a positive definite operator having a discrete spectrum in $\R^+$.

TGF-β inhibitor SB431542 suppresses SARS-CoV-2 replication through multistep inhibition

Journal of Virology
The coronavirus disease 2019 (COVID-19) pandemic highlighted the critical need for broad-spectrum antivirals with high resistance barriers. Here, we demonstrate that SB431542, a selective TGF-β receptor I (ALK5) inhibitor, exhibits potent antiviral ...
