In vitro Induction of primary antibody responses to particulate and soluble protein antigens in T cell—replaced murine spleen cell cultures

Specific antibody responses could be induced in serumfree condition.Specific anti-SRBC or anti-SRBC ghost antibody were induced from anti-Thy treated (T-depleted) murine spleen cells in serum-free culture in the presence of Con A conditioned medium.This induction system may facilitate the study of lymphokine functions on antigen triggered B cells. In T cell-replaced cultures,the antibody responses of B cells could be successfully induced when soluble SRBC membrane proteins were used as antigens.It thus indicates that antigen together with lymphokines are sufficient to drive B cells to become antibody secreting cells in the absence of T cells.The T cell-replaced system provides a more stable way for in vitro immunization and may be applied to monoclonal antibody production when in vivo immunization is difficult to be carried out.
