The role of nuclear factor kappa B (NF-κB) in filarial pathology

摘要

The transcription factor NF-κB promotes immunity by controlling the expression of genes involved in inflammation. Cytokines and pathogen-associated molecular patterns stimulate cell surface receptors, including toll-like receptors, to initiate a signalling cascade resulting in the activation of NF-κB. NF-κB drives the expression of target genes that mediate cell proliferation and release antimicrobial molecules and cytokines to activate an immune response. Filariasis is one of the most complex infections of humans. The actual causes of the heterogeneity in infection are not well understood. However, they have been attributed to differences in inflammatory processes that are immune-mediated, secondary bacterial infections, and host immune-genetics. Elevated production of angiogenic molecules (VEGFs, CEACAM and MMPs) in filarial pathology has been shown to be dependent on phosphorylation and intracellular activation of NF-κB. This review examines the role of NF-κB in filarial pathology and its potential therapeutic options for individuals with the disease.
