Proteome study of cutaneous lupus erythematosus (CLE) and dermatomyositis skin lesions reveals IL-16 is differentially upregulated in CLE.

Background: The objective of the study was to explore the disease pathways activated in the inflammatory foci of skin lesions in cutaneous lupus erythematosus (CLE) and dermatomyositis (DM).

Methods: Skin biopsies acquired from active CLE and DM lesions, patient (PC), and also healthy controls (HC) were investigated. Biopsy sections were examined by a pathologist, inflammatory foci were laser micro-dissected and captured, and proteins within captured tissue were detected in an unbiased manner by mass spectrometry.

Goltz syndrome in males: A clinical report of a male patient carrying a novel variant and a review of the literature.

Here, we report a novel mosaic mutation in the gene in a male Goltz syndrome patient. We also compare the phenotypes of all reported males with a confirmed molecular diagnosis. This report serves to further clarify the phenotype of Goltz syndrome and suggests that expression in males varies.

The host defense peptide LL-37 a possible inducer of the type I interferon system in patients with polymyositis and dermatomyositis.

The type I interferon (IFN) system has recently been suggested to play important and essential roles in the pathogenesis of myositis. However, a clarification of how type I IFNs could function as triggering factor(s) in the pathogenesis of myositis has yet failed. Through activation of the type I IFN system, the host defense peptide LL-37 carries numerous immunomodulatory properties and is implicated in the pathogenesis of several other autoimmune diseases, including systemic lupus erythematosus (SLE).
