Act1: A Psoriasis Susceptibility Gene Playing its Part in Keratinocytes
Unchecked inflammation, impaired keratinocyte differentiation, and heightened host defense responses typify psoriasis. Lambert et al. make clever use of psoriasis patient genetics and whole transcriptome RNA-Seq analysis to implicate Act1 in these seemingly variegated processes by keeping IL-17 receptor signaling in check while supporting differentiation and limiting innate immune responses in human keratinocytes.
