AB  - Introduction Fibronectin (FN) can interact with immunoglobulin G (IgG) molecules affecting the process of physiological elimination and causing abnormal deposition of immune complexes. The aim of the study was to analyze interaction between FN fragments and IgG molecules with different glycosylation profiles in gingival crevicular fluid (GCF) of patients with periodontal disease and healthy controls. Material and Methods The study included 30 patients with moderate and advanced periodontitis and 22 healthy subjects. IgG and FN content in GCF were measured as well as the presence of FN and galactose expression on IgG molecules. Results IgG content in GCF was five times higher in patients with moderate (p lt 0.01) and eight time higher in patients with advanced periodontitis (p lt 0.001) compared to healthy subjects. Also, hypogalactosylated forms of IgG were found in higher concentration in GCF of patients with advanced periodontitis compared to moderate periodontitis and healthy subjects (p lt 0.05). FN fragments of molecular mass 48 - 53 kDa were the most commonly found fragments in all three groups. Furthermore, in patients with advanced periodontitis, fibronectin fragments were attached to IgG molecules. Conclusion IgG and FN fragments form complexes in GCF in patients with periodontal disease and healthy subjects.
AB  - Uvod Fibronektin može da interreaguje s molekulima imunoglobulina G (IgG) i utiče na normalan klirens ili poremećeno deponovanje imunskih kompleksa. Cilj ovog rada je bio da se ispita veza između fibronektina i IgG različitih glikoformi u gingivalnoj tečnosti osoba obolelih od parodontopatije i parodontalno zdravih ispitanika. Materijal i metode rada U studiju je uključeno 30 pacijenata s umerenom i uznapredovalom parodontopatijom i 22 parodontalno zdrave osobe. U gingivalnoj tečnosti određivan je sadržaj IgG i fibronektina dot blot i imunoblot tehnikama. IgG iz gingivalnih tečnosti su afinitetno izolovani i analizirani na prisustvo fibronektina i ekspresiju galaktoze. Rezultati Sadržaj IgG u gingivalnoj tečnosti osoba s umerenom parodontopatijom bio je oko pet puta veći u odnosu na sadržaj IgG kod zdravih osoba (p lt 0,01), dok je kod uznapredovalih oblika bio oko osam puta veći (p lt 0,001). Takođe, hipogalaktozilovane forme IgG su većoj meri postojale kod osoba sa uznapredovalom parodontopatijom u odnosu na zdrave i osobe s umerenom parodontopatijom (p lt 0,05). U sve tri analizirane grupe dominirali su fibronektinski fragmenti od 48 do 53 kDa. Uočeno je da su IgG izolovani iz gingivalne tečnosti vezani za fragmente fibronektina, pri čemu su IgG osoba sa uznapredovalom parodontopatijom, imali najveću količinu ovih vezanih fragmenata. Zaključak Dobijeni rezultati pokazuju da IgG gingivalne tečnosti zdravih i osoba s parodontopatijom formiraju komplekse sa fibronektinom.

AB  - Background: Fibronectin (FN) can bind to immunoglobulins (Ig), influencing both the normal clearance and abnormal deposition of circulating immune complexes. This study focuses on the possible interaction between FN and IgG present in gingival crevicular fluid (GCF) of periodontitis patients and periodontally healthy controls, with the aim to determine whether such interaction may be connected with the glycosylation profile of IgG and, thus, consequentional in accumulation of proinflammatory IgG in periodontal pockets. Methods: The study included 30 patients with initial or advanced periodontitis, and 13 periodontally healthy subjects. GCF IgG was purified and analyzed for the presence of FN and its fragments and for galactose expression. Results: IgG isolated from GCF contained FN, which was bound to the IgG heavy chains. IgG from GCF of advanced periodontitis patients contained high levels of hypogalactosylated IgG, and bound more FN than IgG from GCF of the other two groups, which contained low levels of this glycoform. FN was in a degraded form in GCF from all studied patients, and a fragment of 48- to 53-kDa molecular mass seemed to be the sole one linked to IgG. Conclusions: IgG and the FN fragment of 48 to 53 kDa in GCF of periodontitis patients and periodontally healthy subjects are physically connected. This fragment was linked to the heavy chains of IgG and the reaction seemed to be particularly intensive with IgG from advanced periodontitis, which contained significantly less galactose in its sugar chains.

AB  - Background: Altered glycosylation of immunoglobulin G (IgG) has been found to affect certain immunological activities of IgG and to correlate with increased inflammation in various disease states. This work deals with the changes in distribution and galactosylation of IgG subclasses present in saliva and gingival crevicular fluid (GCF) of patients with initial and advanced periodontitis and of normal controls. Methods: IgG subclasses were quantified by dot-blot assay, and the degrees of expression of galactose in the total IgG and its individual subclasses were estimated by lectin immunoblot assay after sodium dodecyl sulfate - polyacrylamide gel electrophoresis (SDS-PAGE) separation of IgG and by capture enzyme-linked immunosorbent assay (ELISA), using biotinylated Ricinus communis (RCA-1) and Bandeiraea simplicifolia (BS-II) lectins. Results: The distribution of IgG subclasses in both fluids was found to differ in periodontal patients compared to normal controls. In the periodontitis saliva and GCF, the IgG2 subclass dominated quantitatively, regardless of periodontal status. However, galactose was found to be expressed in IgG heavy chains in normal controls and patients with initial periodontitis but not, or at barely detectable levels, in advanced periodontitis. Conclusion: The results suggest that the shift toward hypo-galactosylated glycoforms may occur during the process of inflammation of the gingiva.

Aim: This work analyses the distribution of IgG subclasses and the content of thermal galactose in them, in saliva and gingival fluid of the patients with periodontal disease and different gum inflammatory level. Materials and methods: It was used saliva and gingival fluid of 30 adults with clinical picture of periodontal disease and 20 persons with healthy periodontium. The qualification of IgG was done by “dot-blot” procedure and the, and thermal galactose was determined by lectin immunoblot procedure. Results: The division of IgG subclasses in both fluids was different in the patients with periodontal disease and in control samples. In saliva and gingival fluid of the diseased quantitatively dominated IgG2 subclasses, independently from periodontal status. In IgG of both fluids, thermal galactose was exprimated at the healthy periodontium persons (control) and with the person with initial periodontal disease, while at the person with increased periodontal disease the expression of this saccharide wasn’t registered in neither of fluids. Conclusion: The results showed that there is a shift towards hypogalactosyled IgG glikoforms during the process of gum inflammation at the periodontal disease patients.
