<br/><br/> Macrophages and ganglioside-specific immunoglobulin G (IgG) are involved in the pathogenesis of guillain - barre syndrome (GBS). Leukocyte IgG receptors (FcÞR) confer potent cellular effector functions to the specificity of IgG. The efficacy of IgG - mediated cellular inflammatory responses is determined by functional polymorphisms of three FcÞR subclasses (FcÞRIIA: H131/R131; FcÞRIIIA: V158 / F158; FcÞRIIIB: NA1/NA2). FcÞR genotype distributions were determined in some cohorts of GBS patients and controls. The purpose of our study was mainly to investigate the role of the host immunogenetic factors like high affinity FcÞR polymorphism in the development of GBS compared to controls and their association with commonly described antecedent infections, electrophysiological subtypes, severity and outcome of GBS
