Epstein Barr virus antigen-induced autoantibodies against complement C1q exacerbate renal disease in lupus-prone mice [PDF]
Frontiers in ImmunologyBackground and AimsSystemic Lupus Erythematosus (SLE) is a complex autoimmune disease characterized by the development of autoantibodies against multiple antigens, including complement C1q, starter molecule of the classical pathway.

Engineering C1q single-chain globular head variants for enhanced IgM binding [PDF]
BMC BiologyBackground The initiation of the classical complement pathway begins with the binding of the globular head of complement component 1q (C1q) to antigen-bound immunoglobulin M (IgM).

Clinical and Experimental Immunology, 2003 SUMMARY Anti-C1q autoantibodies are present in the serum of patients with different autoimmune diseases such as systemic lupus erythematosus (SLE). The occurrence of these autoantibodies correlates with renal involvement. In the present study we examined whether injection of rabbit antimouse C1q antibodies in mice leads to deposition in ...

C1q Is Recognized as a Soluble Autoantigen by Anti-C1q Antibodies of Patients with Systemic Lupus Erythematosus [PDF]
AntibodiesBackground and Aims: C1q is an autoantigen in different autoimmune disorders, Systemic Lupus Erythematosus (SLE) and Lupus Nephritis (LN) among them. The two functional domains of C1q, the collagen-like region (CLR) and the globular head region (gC1q ...

The role of complement component C1q in angiogenesis
Exploration of Immunology, 2023 The complement component C1q plays a role as a pro-angiogenic factor in different contexts, acting in a complement-independent way. For example, this molecule is able to foster the remodeling of the spiral arteries for a physiological pregnancy and to ...

Change in C1q deposition in C1q nephropathy [PDF]
Pediatric Nephrology, 2009 Sirs, We read with interest the article entitled “A single-center study of C1q nephropathy in children” by Roberti et al. in the latest issue of this journal [1]. They reviewed the records of 14 children with C1q nephropathy (C1qN) and found a high incidence in pediatric patients (14/264, 5.3%), with variable clinical presentation.

A non-redundant role of complement protein C1q in normal and adverse pregnancy
Exploration of Immunology, 2022 Complement component 1q (C1q) is the recognition molecule of the classical pathway of the complement system that can bind to an array of closely spaced antigen-bound immunoglobulin G (IgG) and IgM antibodies.
