Patients with alcohol‐associated hepatitis (AH) and alcohol‐cirrhosis (AC) show perturbations in complement. Complement activation pathways are perturbed in the urine of patients with AH and AC, and distinguish severe AH from AC. Complement perturbations can help physicians and researchers to understand the liver–kidney crosstalk in severe AH and AC ...

Abstract Background and Purpose Overactivation of the alternative pathway (AP) underlies several diseases. Iptacopan is an oral, first‐in‐class, highly potent specific inhibitor of factor B, a key AP protease. Experimental Approach The analysis included data from two phase 1 randomised, volunteer‐blinded, placebo‐controlled studies: Study 1, a single ...

Complement C3 is the central component of the human complement system. It is ~186 kDa in size, consisting of an α-chain (~110 kDa) and a β-chain (~75 kDa) that are connected by cysteine bridges. C3 in its native form is inactive. Cleavage of C3 into C3b (

Complement activation leads to C3 & C5 dependent prothrombotic alterations of fibrin clots
Alterations of the fibrin network structure with thin fibrin fibers, increased fiber density, small pores, and hypofibrinolysis are associated with an increased risk of cardiovascular diseases.

Activation of the Lectin Pathway Drives Persistent Complement Dysregulation in Long COVID
The complement cascade, a series of blood proteins that assists in the recognition and neutralisation of pathogens, either independently or in conjunction with antibodies, is persistently activated in patients with long COVID. We found that blood plasma samples from patients with long COVID contained elevated concentrations of the mannan‐binding lectin‐

Principles of novel complement convertase assay.
Classical complement convertases are assembled on sheep erythrocytes sensitized with antibodies and incubated with C3 or C5-depleted serum. The lack of a particular component allows the complement cascade to proceed only to the stage of classical C3 ...

Abstract Ischemia‐reperfusion injury (IRI) is a prevalent condition that predominantly afflicts hospitalized patients, inducing acute kidney injury (AKI). In recent years, complement 5 (C5) and its anaphylatoxin receptor C5aR1 have been implicated in driving kidney IRI and loss of function.

Staphylococcal complement inhibitor modulates phagocyte responses by dimerization of convertases.
The human pathogen Staphylococcus aureus produces several complement-evasion molecules that enable the bacterium to withstand the host immune response. The human-specific staphylococcal complement inhibitor (SCIN) blocks the central C3 convertase enzymes

Borrelia burgdorferi sensu lato Employs Several Escape Mechanisms to Bypass the Human Defense System
Integrated overview of host defense and immune evasion in Lyme Borreliosis. Bbsl evades immunity through tick saliva‐mediated suppression of innate defenses, TLR2/NOD2‐driven cytokine dysregulation, and interference with JAK/STAT and CIITA‐dependent antigen presentation.
