Anti-Inflammatory Activity of Immunoglobulin G Resulting from Fc Sialylation

Immunoglobulin G (IgG) mediates pro- and anti-inflammatory activities through the engagement of its Fc fragment (Fc) with distinct Fcg receptors (FcgRs). One class of Fc-FcgR interactions generates pro-inflammatory effects of immune complexes and cytotoxic antibodies. In contrast, therapeutic intravenous gamma globulin and its Fc fragments are anti-inflammatory. We show here that these distinct...

Comparative analysis of rosacea and cutaneous lupus erythematosus: histopathologic feat...
Journal of the American Academy of Dermatology; Brown TT, Choi EY et. al.

Mar 24th, 2014 - Distinction of rosacea and cutaneous lupus erythematosus (LE) can be challenging because of significant clinical and histologic overlap. A controlled study comparing these conditions is lacking. We compared the histologic features, T-cell subsets, and plasmacytoid dendritic cells in rosacea and LE. Biopsy specimens of rosacea (n = 27) and facial LE (n = 30) were retrospectively reviewed and rea...

Two clinical phenotypes in polycythemia vera.
The New England Journal of Medicine; Spivak JL, Considine M et. al.

Aug 27th, 2014 - Polycythemia vera is the ultimate phenotypic consequence of the V617F mutation in Janus kinase 2 (encoded by JAK2), but the extent to which this mutation influences the behavior of the involved CD34+ hematopoietic stem cells is unknown. We analyzed gene expression in CD34+ peripheral-blood cells from 19 patients with polycythemia vera, using oligonucleotide microarray technology after correctin...
