Complement component C3: A structural perspective and potential therapeutic implications

Seminars in Immunology, 2022
As the most abundant component of the complement system, C3 and its proteolytic derivatives serve essential roles in the function of all three complement pathways. Central to this is a network of protein-protein interactions made possible by the sequential proteolysis and far-reaching structural changes that accompany C3 activation.

The Renal Activity Index for Lupus Identifies Active Renal Disease and Treatment Response in Adult Patients With Systemic Lupus Erythematosus and Lupus Nephritis

Arthritis Care &Research, EarlyView.
Objective We evaluated the ability of the Renal Activity Index for Lupus (RAIL) to discriminate active lupus nephritis (LN) in adult patients with active systemic lupus erythematosus (SLE) and differentiate LN treatment response. Methods Urine samples from adults with biopsy‐proven active class III and IV LN from TULIP‐LN (active LN group ...

Complementing antibody profiles: Assessing antibody function on antigen microarrays [PDF]

, 2012
Antibody effector functions other than neutralization depend on interactions with soluble and cellular components of the immune system. Antigen recognition is usually oligoclonal, with the different clones of antibodies belonging to different ...

Role of Prednisone and 25‐Hydroxyvitamin D on Bone Mineral Density and Osteoporosis in Systemic Lupus Erythematosus

Arthritis Care &Research, EarlyView.
Objective We evaluated the role of 25‐hydroxyvitamin D (25[OH]D), prednisone, and other risk factors for bone mineral density (BMD) loss and osteoporosis in systemic lupus erythematosus (SLE). Methods We calculated the association between 25(OH)D levels and other potential risk factors and BMD measures (spine T scores) and osteoporosis (defined as a T ...

Kidney Diseases Caused by Complement Dysregulation: Acquired, Inherited, and Still More to Come

Clinical and Developmental Immunology, 2012
Inherited and acquired dysregulation of the complement alternative pathway plays an important role in multiple renal diseases. In recent years, the identification of disease-causing mutations and genetic variants in complement regulatory proteins has ...

Cutaneous vasculitis and recurrent infection caused by deficiency in complement factor I [PDF]

, 2018
Cutaneous leukocytoclastic vasculitis arises from immune complex deposition and dysregulated complement activation in small blood vessels. There are many causes, including dysregulated host response to infection, drug reactions, and various autoimmune ...

Rheumatologic Manifestations of Patients With Type B Insulin Resistance

Arthritis Care &Research, EarlyView.
Objective The objectives of this study were to identify laboratory and clinical features associated with type B insulin resistance (TBIR), a rare condition caused by autoantibodies that inhibit the insulin receptor, most frequently occurring in the setting of systemic lupus erythematosus (SLE), and to increase awareness of this rare, life‐threatening ...

C1q acts in the tumour microenvironment as a cancer-promoting factor independently of complement activation [PDF]

, 2015
Complement C1q is the activator of the classical pathway. However, it is now recognized that C1q can exert functions unrelated to complement activation.
