Abstract

The purpose of this study was to investigate and compare adjuvant effects of soluble ß-glucans from barley and Saccharomyches cerevisia in induction of antigen specific humoral immune responses. Mice were immunized with conalbumin at a relatively low con- centration in the presence of beta glucans. Anti-conalbumin antibodies in the sera of immunized and control mice were quantified by ELISA. At high doses, both of glucans increased effectively levels of circulating IgM and IgG antibodies which were specific for conalbumin. However, coadministration of glucan from barley at 1 µg dose resulted in lower yield in IgG1, IgG2a, IgG2b, and IgA le- vels in comparison to that of yeast-derived glucan at the same dose. We also found that antigen (conalbumin) specific antibody le- vels enhanced by ß-glucan from Saccharomyches cerevisia were always higher than those of the glucan from barley. Based on the- se findings, we concluded that (1,3),( 1,6)-ß-D-glucan from yeast cell wall might have superior immunostimulant activity in induction of antigen specific humoral immune responses over (1,3),( 1,4)- ß-D-glucan from barley.

Özet

Bu çalışmanın amacı antijene özgül hümoral immün cevabın oluşması sırasında arpa ve Saccharomyches cerevisia’dan elde edilen çözünebilir ß-glukanların adjuvan etkilerinin araştırılmasıdır. Fareler beta glukan varlı¤ında göreceli olarak düşük dozlarda konalbümin ile immünize edildi. immünize edilmiş ve edilmemiş kontrol fare serumunda anti-konalbumin antikorları ELISA yöntemi ile tayin edildi. Yüksek dozlarda uygulandığı zaman her iki glukan konalbümine özgül IgM ve IgG antikor seviyelerini etkin bir şekilde arttırdı. Ancak, aynı dozda maya (Saccharomyches cerevisia) kökenli glukan ile karşılaştırıldı¤ında, konalbümin ve 1 µg arpadan elde edilen glukanın birlikte enjeksiyonu, daha düşük seviyelerde IgG1, IgG2a, IgG2b, and IgA üretimine neden oldu. Saccharomyches cerevisia köken- li glukan tarafından arttırılan antijene özgül antikor seviyeleri, arpa kökenli glukan tarafından arttırılan antijene özgül antikor seviyelerin- den daima daha fazla oldu. Bu sonuçlar temel alınarak antijene özgül hümoral immün yanıt oluşmasında, mayadan elde edilen (1,3),( 1,6)-ß-D-glukanın, arpadan elde edilen (1,3),( 1,4)- b-D-glukan’a göre daha fazla immünostimülan aktiviteye sahip oldu¤u düşünüle- bilir.
