A full complement of receptors in immune complex diseases

A full complement of receptors in immune complex diseases.

In this issue of the JCI, Shushakova et al. (1) describe experimental results that provide a direct link between the C5a anaphylotoxin and the IgG Fc receptors (FcγRs) in mediating immune complex–triggered (IC-triggered) inflammatory disease. Using a murine lung model of IC-induced inflammation, the authors demonstrate that C5a, acting through the C5a receptor (C5aR), exacerbates inflammation i...

Immune Environment in a B Cell Complement Receptors

Serum complement profile in human leprosy and its comparison with immune complex diseases.

In the present study we have estimated the serum levels of early, middle, and distal complement components, e.g., Clq, C3, C4, C5, C8, and C9 along with C1-inactivator and CH50 in patients with tuberculoid and lepromatous leprosy and have compared these results with the levels in healthy subjects as well as with levels in patients with other immune complex diseases. We have also analyzed the cr...

The role of complement in cryoglobulin-induced immune complex glomerulonephritis.

Many forms of glomerulonephritis are triggered by Ab localization in the glomerulus, but the mechanisms by which this induces glomerular inflammation are not fully understood. In this study we investigated the role of complement in a mouse model of cryoglobulin-induced immune complex glomerulonephritis. Several complement-deficient mice on a C57BL/6 and BALB/c genetic background were used and c...

Vitiligo and auto immune diseases: A survey of 100 patients

Vitiligo is an autoimmune skin disease which is characterized by depigmented patches due to loss of pigment cells. Evidence suggests that cell-mediated immunity plays a role in melanocyte destruction while some patients have antibodies to melanocytes or melanocytic proteins. Vitiligo is strongly associated with a number of autoimmune disorders. Autoimmune thyroiditis is the most prevalent disea...
