The presence of cathelicidin antimicrobial peptides provides an important mechanism for prevention of infection against a wide variety of microbial pathogens. The activity of cathelicidin is controlled by enzymatic processing of the proform (hCAP18 in humans) to a mature peptide (LL-37 in human neutrophils). In this study, elements important to the(More)
Metastatic progression depends on genetic alterations intrinsic to cancer cells as well as the inflammatory microenvironment of advanced tumours. To understand how cancer cells affect the inflammatory microenvironment, we conducted a biochemical screen for macrophage-activating factors secreted by metastatic carcinomas. Here we show that, among the cell(More)
IkappaB kinase alpha (IKKalpha), one of the two catalytic subunits of the IKK complex involved in nuclear factor kappaB (NF-kappaB) activation, also functions as a molecular switch that controls epidermal differentiation. This unexpected function requires IKKalpha nuclear translocation but does not depend on its kinase activity, and is independent of(More)
The calcipotriol/betamethasone dipropionate fixed-combination gel is widely used for topical treatment of psoriasis vulgaris. It has been hypothesized that calcipotriol counteracts glucocorticoid-induced skin atrophy which is associated with changes in the extracellular matrix (ECM). To elucidate the combined effects of calcipotriol and betamethasone on key(More)
