STATE OF ACTIN POLYMERIZATION IN B LYMPHOCYTES FROM DIFFERENT DEVELOPMENT STAGES OF BURSA OF FABRICIUS OF PEKING DUCK / 解剖学报

ABSTRACT

In this study we have examined the state of actin polymerization in B cells from different development stages in bursa of Fabricius of Peking duck by indirect immunofluorescence technique using antibody against actin. In B cells from bursa of Fabricius of 26th day embryo and 3th week after hatching, the polymeric actin was the main form in the actin pool. In B cells from bursa of Fabricius of 12th week after hatching, however, the monomeric actin was the main form, which might be a result of the shift from the polymeric actin pool to the monomeric pool. We concluded that the state of actin polymerization might be an important factor in the cellular functions of B cells of bursa of Fabricius.
