Mutations in the alternative complement pathway in multiple myeloma patients with carfilzomib-induced thrombotic microangiopathy [PDF]

, 2023
Thrombotic microangiopathy (TMA) has been reported to occur in multiple myeloma (MM) patients in association with treatment with carfilzomib, an irreversible proteasome inhibitor (PI).

Bloqueo del complemento: promesas terapéuticas y retos pendientes en la práctica clínica

Nefrología
Resumen: La comprensión del complemento en las glomerulopatías ha avanzado notablemente, mostrando que este sistema, más allá de la inmunidad innata, es un mediador clave del daño renal en un amplio espectro de nefropatías, desde las mediadas por ...

Components of the alternative complement pathway in patients with psoriasis

Acta Dermatovenerologica Alpina Pannonica et Adriatica, 2017
Psoriasis is a chronic inflammatory skin disease. Adipose tissue plays important roles in the events that regulate body metabolism. This study determined the levels of complement 3 ( C3), acylation-stimulating protein (ASP), and adipsin, which take part in the alternate complement pathway, and are synthesized in and secreted by adipose tissue.Thirty ...

Methylprednisolone inhibits the alternative and amplification pathways of complement [PDF]

Infection and Immunity, 1982
Methylprednisolone sodium succinate limited the ability of zymosan or lipopolysaccharide to activate complement in normal serum by the alternative amplification pathways. Methylprednisolone limited B consumption in a reaction mixture which contained purified C3b, D, and B, indicating that soluble steroid directly inhibited the amplification pathway ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

PolySialic Acid Nanoparticles Actuate Complement-Factor-H-Mediated Inhibition of the Alternative Complement Pathway: A Safer Potential Therapy for Age-Related Macular Degeneration

Pharmaceuticals
The alternative pathway of the complement system is implicated in the etiology of age-related macular degeneration (AMD). Complement depletion with pegcetacoplan and avacincaptad pegol are FDA-approved treatments for geographic atrophy in AMD that, while

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Small-molecule factor D inhibitors selectively block the alternative pathway of complement in paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome

Haematologica, 2017
Paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome are diseases of excess activation of the alternative pathway of complement that are treated with eculizumab, a humanized monoclonal antibody against the terminal complement ...

Activation of the alternative complement pathway by Trichomonas vaginalis [PDF]

Infection and Immunity, 1981
The mechanism underlying the lysis of Trichomonas vaginalis by normal human or guinea pig serum was investigated. The involvement of the complement system was demonstrated by the failure of human serum deficient in C3 or C8 to mediate parasite killing and by the ablation of lytic activity observed when fresh sera were heated at 56 degrees C or treated ...
