Contribución de variantes funcionales y cuantitativas del Factor H y las proteínas FHRs (Factor H-Related proteins) del Complemento en patología renal

Nefrología, 2022
Resumen: El sistema del Complemento protege al organismo frente a procesos infecciosos, tumorales y autoinmunes, y requiere una regulación muy estricta para evitar una activación excesiva o inespecífica.

Reference Intervals of Factor H and Factor H-Related Proteins in Healthy Children

Frontiers in Immunology, 2018
Complement is activated as part of the innate immune defense against invading pathogens. Also, it helps to remove apoptotic debris and immune complexes from the circulation.

Truncated forms of human complement factor H [PDF]

Biochemical Journal, 1989
By the use of Western-blot analyses with polyclonal anti-(Factor H) antibodies, two low-Mr protein species of Mr 41,000 and 37,000 under non-reducing conditions and 43,000 and 40,000 under reducing conditions are consistently detected together with the well-known 155,000-Mr Factor H in human plasma and serum. These two additional species are also found

Human complement factor H. Two factor H proteins are derived from alternatively spliced transcripts [PDF]

, 1991
The human complement factor H is an important component in the control of the alternative pathway of complement activation. We have previously shown that at least three factor H homologous mRNA species of 4.3 kb, 1.8 kb and 1.4 kb in length are ...

Complement factors (H) into thrombosis [PDF]

Blood, 2017
In this issue of Blood, Ueda et al demonstrate that a mutation in factor H (FH) disrupts host cell interactions, leading to dysregulation of complement, systemic thrombotic angiopathy, and hemolytic uremic syndrome ...

The complement factor H‐related proteins

Immunological Reviews, 2016
SummaryThe role of the complement factor H‐related (FHR) proteins in homeostasis, pathogen defense, and autoimmune disease has recently attracted considerable interest. We highlight the exciting research that has contributed to our understanding of the FHR protein family. Unlike factor H, a potent negative regulator of complement C3 activation, the FHR

Factor H Family Proteins in Complement Evasion of Microorganisms

Frontiers in Immunology, 2017
Human-pathogenic microbes possess various means to avoid destruction by our immune system. These include interactions with the host complement system that may facilitate pathogen entry into cells and tissues, expression of molecules that defuse the ...
